When I saw that you posted this longer video, honestly got excited. Since I like your starlink content. Also I don't understand how people don't have the patience to watch a 10 minute video or more
The most significant fact about Starlink lasers, commercially, is that now they can get securities market price and transaction data across oceans (e.g. between New York and London or Hamburg) several milliseconds ahead of the same data on existing fiber. (This, BTW, has nothing to do with bandwidth.) Any investment bank / hedge fund with exclusive access to such data can rake in extra $billlions, so if SpaceX is not metering out access to that capability, or taking advantage exclusively themselves, they are walking away from $billions. There are also military applications for such latency benefits, so the US military is in the middle of constructing its own low-earth constellation. One such application is piloting remote-control aircraft from a desk in the Pentagon. Ground stations will not be going away, at all. _All_ traffic between literally anybody without a Starlink terminal and communicating with somebody who is on a Starlink terminal will be going through a ground station, forever. The fraction of traffic going directly between users both on Starlink terminals will be negligible. Placing a network operations center in orbit would offer Starlink no benefit, so is unlikely to happen: latency between a NOC and Starlink satellites is unimportant.
I thought so. Speaking with my wife in Tokyo from upper Michigan over ip has been simply amazing quality with none of the the delays where we talk over each other.
Keep doing what you do man. Short or long, your videos are some of the most informative videos out there. I appreciate your time and explanations with the content you put out. Don’t get caught up worrying about the few that just want the microwaveable version or quick answers. Those folks are not your target audience so don’t bother explaining why the vids need to be “long” so they don’t get their feelings hurt.
Hi JC. Love your channel. I'm a military satellite communications engineer. The math where you multiply the # of lasers by the speed of each laser, isn't how it works. Basically you want to compare the throughput of the system with and without lasers. You have the concept basically correct in that the "w/ laser" network transfers data faster than without. Without, you go from your house in Miami to a satellite, back down to ground station, terrestrially to a POP, then at the "speed of the internet" to the server you want to connect with, let's say in Los Angeles. Then in reverse. The satellite to satellite laser comms basically replaces the cross country terrestrial "internet" leg of journey. So basically, you simply compare the speed of terrestrial internet to the speed of the laser comms. With lasers, the journey would be from your house in Miami, up to Starlink satellite, THEN, at LASER COMM SPEEDS, to a Starlink satellite over LA, then down to ground station of POP, then via internet to the server in LA. If the laser comms is at 100 Gbps, you would compare that to the "speed of the internet" in the "w/out laser" scenario. The throughput in the "w/ laser" scenario is more, and the speed is more, but you don't multiply EACH laser link. The fastest you will be able to achieve is the 100 Gbps inherent in the laser comms speed. When talking about data comms, you also need to pay particular attention to the speed AND the throughput. A good anology is trucks on the interstate. Trucks carry your data from your house to mine. If the road has 4 lanes, and the trucks and drive 100 mph, and each truck carries 1 Byte of data, you get 4 Bytes at 100 mph. But if you have 1 lane but the trucks drive at 1,000 mph, you get a lot more data faster. Lasers are like 1,000 mph 18 wheelers on a 1 lane road.
I'm not sure what exactly was the big secret… Everyone has known about this for over a year. Star link has "space lasers" T-shirts for the employees that they've been wearing around publicly for over a year.
When you mentioned NOCs in space, it sparked this idea - How about a distributed database and blockchain network in space? Important global information could be permanently stored and retrieved by anyone - regardless of what any individual nation state or corporation tried to do to "block the internet". Even better, once subnets of satellites begin orbiting the moon and Mars, the same data could be consistently replicated to and from those places as well.
Theoretically if they can use laser comms all the way from New York to London then the route is actually faster than the fibre-optic cable connection which is worth a lot to traders (billions).
The really amazing thing about Starlink laser links is that it enables city-grade internet everywhere on the planet, which is a massive game changer. Hapag-Lloyd is rolling out Starlink to all their 258 massive container ships, for crew communications and vital operational comms, and it won't be long before this is compulsory for all modern shipping and fishing fleets (for compliance reasons as well as operational and crew). A really cool aspect for low density populations like NZ, Australia, mid-ocean etc.) is that Starlink is sized for the high density northern hemisphere, which means low density areas get consistently extreme performance.
Could you break down the whole starlink more even though I have it and watched about all of your videos lol... if possible use an Etch-A-Sketch ... Love your videos... people will complain about anything.. thank you always for the info you provide on SL.
The issue will still be the latency in the up/down from satellite to ground. The latency will not be able to be as fast as fiber. Yes the speed in orbit will be faster, but it’ll be throttle still beaming up and down.
Awesome update and excellent content. If I'm interpreting your math correctly eliminating ground stations cuts out 20% or so of the latency producing steps. Then using lasers reduces further cuts latency by 40%.
The biggest reason for this upgrade that you missed is that if you don’t have the lasers, you can only communicate if the satellite can see you AND a ground station. But now as long as you can see any satellite with a laser and that satellite can see more, and so on, until it hits one that can see a ground station, you are good. Realistically this allows you to cover the entire world with theoretically only one ground station. Obviously would still have more, but now if the ground station for Central America goes down because of a storm or for maintenance, the laser links just let you connect to a different station.
You spent the first 2 minutes talking about how you don't get to the point and people get upset at how long it takes you to get to the point. This is literally the first video I've ever seen from you and I am leaving now good job bud you're a genius!
Thank you for your Starlink info videos, as a retired Navy Radioman I used alot of HF to transmit message traffic, for long distances ie Med Sea to Red Sea to hear 'Lasers' is AWESOME. THANK YOU for your explanation. PEACE
Agreed, it wouldn’t make sense to spend the significant sums of money to launch the satellites with non-redundant link capabilities (lasers in this case), I’d expect there are also cold standby lasers, and that any single satellite communicates with several others, thus requiring more than 2 lasers. Given that some of the Starlink capabilities are used by the US military, would be very unsurprising that there are aspects not made known to the public.
Light is just very high radio frequency. The visible window is between 300-750 THz (300,000 to 750,000 GHz). The higher the frequency (which produces shorter wavelength) the narrower the beam-width for a given antenna size. RF and Light travel at the speed of C in free space. Both slow down in air and slower still in water (RF is attenuated rather quickly in water). This is why fiber (laser based) is so much slower than laser in space (glass is much more dense). [Besides trying to hook two satellites together via fiber is an exercise in futility.] The main advantage of laser over lower frequency RF is the beam-width advantage of the laser. It is a much smaller "spot" for laser (making it harder to aim) but preserves the power density. At 14 GHz with a 1 meter dish the RF beam-width is 1.25 degrees. So at 1,000 miles (presumed distance between satellites) the half-power beam-width is almost 22 miles side. Even with the curvature of the earth and LEO, the possibility another satellite would be illuminated is fairly high. The laser though has a much narrower beam-width at .0716 degrees (presuming the laser exit hole is 1mm and not 1m as for the dish). At that same 1000 miles the half-power beam-width is 1.25 miles. Much harder to aim but more likely to illuminate only the target satellite. The power in the signal is spread over a much smaller area meaning the receiver will get a much higher percentage (power falls over at the square of the distance). BTW, hams are licensed for any frequency over 300 GHz
Fiber optic cables of course use lasers as well, but the light has to travel through the medium of glass, which slows it down. It also has to pass through multiple repeater stations to get to its destination if travelling any significant distance. Depending on the laser used, between multiplexing and using various frequencies of light, fiber might be able to transmit *more* data/sec but it will be slower. Having said that, there are quite possibly frequencies that cannot be used in fiber that can be used when just passing through “space”. Technically there is still a very sparse amount of atmosphere present at the altitude that Starlink orbits at, but likely presents negligible effects on the beam, especially beam dispersion.
thank you so much for all that you present for us ❤️ really it's very hard for you. I like them. I always follow your videos, especially related to Starlink .. Thank you so much .. best wishes for you from Iraq ❤
Are these lasers a visible wave length of light, or infrared or something else. So what if all satellites with a line of sight were to transmit their laser to one focal point on land?? Would that create enough energy to start a fire?
My guess is that each link uses 2 lasers: Transmit and confirm of the reception. for error correction. In this case your total network transfer capacity is half of what you calculated.
I’m wondering if SpaceX can shut down particular areas of say, certain Continents? Like do we really want our adversaries being able to use this technology against us?
@@fredbloggs5902or say they do but militarily they will attempt to use it. Like a burglar with a crowbar, but then the business has the key hidden under the Welcome mat.
Great Venting! You doing a great job J. and I subscribe to your channel because of all the content. Thanks for all the work you put into your content and channel. I'm thrilled about it and hoping for more speed up and down.
Great info! Always figured something like this was going to happen. But how are these going to be protected from enemies trying to stop this? Again great stuff and able to understand all of it. You the man!😊
What will be the performance for the lasers through rain/smoke? What will be the impact on latency…still faster than fiber, maybe an offset. Awesome video again!
Too long of a video? Nope. It was just over 10 minutes for me and I enjoyed every minute of it and am better informed because of it. Why? because you speak so clearly and accurately that I can listen at 2X speed and not miss a detail of your excellent presentation. Thank You! Subscribed.
It's not the subject of that video but I'd like to know something, maybe it don't apply to starlink, but it's a shared connexion , right ? What is the ratio ? I tried to find that information anywhere I could but I didn't find it ?
What you're really alluding to is - Verizon, T-Mobile, AT&T, Google Fi, Mint Mobile - will go the way of the type setting "Linotype" machine when the Macintosh 128K nicknamed the "thin Mac" industry disruptor was introduced in 1984 - "Because 1984 won't be like 1984"
I personally like all your contents thou i might not comment a lot but honestly i hear really commend you for taking the time out to research so that we can be enlightened and aware of whats going on out there. personally i dont mind how long your videos are cause they are very interesting. so thanks for all the hard work that you have put into all your contents. if you need an hour to get you information out then so be it. your viewer from the small Island of Jamaica
12:43 This really was a very informative video. Also very detailed, good video 👍. Also I also understand what you’re explaining. A router with access points was a good example. It is definitely going to speed up, This will help latency so much
so, the ground stations don't "go away", they get reduced/combined with pops. The biggest hurdle for latency has got to be the home satellite dish, which isn't changing with the laser mesh network is it? Also, wouldn't it make sense to incorporate the router functions directly into the new satellites?
You are my most watched content. You're greatly appreciated. Also I sent you an email telling you about what I found d out about starlink mesh routers. Thank you for what you do
If you think the video does not come fast enough - turn up the speed for the video to 1.25, 1.5, 1.75 or 2.0 X speed through the gear menu on the video interface. I do that for many videos. I find it easy to listen to most videos at 1.5X speed without loosing any information..,
How about the rounding at this around 500km above us in space? I mean lasers can not really shoot (piew piew) around the corner, can they ? So they should be relative close to each other right ? Thanks for the video by the way ...
As someone working in the telco industry this is my comment: You still have to enter the terrestrial internet at some point, and that point should be as close to the terrestrial destination as possible. So there still will have to be many terrestrial POPs across the globe, so there is really no point of doing NOC in LEO.
Base stations are necessary for the following reasons. When using the Internet in Europe, I use many websites with servers in Europe. If the base stations remained only in the USA (these satellites have to transmit data somewhere), the signal would be transmitted from Europe 8,000 km to the USA via a network of lasers (at best 26 ms because the speed of light is 300 km/ms). Then these packets would return via the terrestrial network from the USA to Europe. From my country I have 100-150 ms to servers in the US so the delay would be huge. Therefore, the base stations must remain regional, otherwise the delay will increase due to international routing, and the laser link system will be used over the oceans.
I watch RUclips channels mostly for long form content. If I wanted it condensed to 1 minute I'd watch some shorts. Just ditched my dual bonded CenturyLink DSL and switched to starlink and your content helped me make that informed decision!
Haha, I love picking on the dorks who don't know how to operate the basic features of a youtube video to skip ahead, adjust the volume, don't recommend for click bait channels, etc.. That being said, adding a couple chapter markers (if for some reason you ever feel bad for them) are very useful.
Joe: I think you missed a detail. The space resident Starlink mesh MUST connect to the terrestrial "backbone fiber" preferably at high bandwidth fiber locations SOMEHOW. That's why the Ghz microwave antennae are on each satellite to access customer ground terminals AND ground stations which may be close to a POP. I don;t know how many phased array antenna are on each satellite. Some Starlink satellites need to access a ground station near a POP. Starlink mesh will still need "Terabits" of microwave links to the ground. The POPs will certainly be encrusted with microwave "mushroom" antennae. Ground station relay points should disappear . POPs won't. Lasers don't do well in the atmosphere which is why microwaves are used. Microwaves DO get attenuated by rain, snow... especially in the higher Ghz range. Happens to me with my Starlink V2 "candybar. The satellite lasers may be fairly cheap in large quantities while ground stations aren't. I can't wait to see how much the Starlink network performance increases!
NOCs in space is an obvious evolution of Skyne... I mean Starlink. I can also foresee having parts of the internet mirrored on satellites. Did you just say 10 ms latency ways better than 7 ms latency?
I've watched two different starlink "constellations" apparently crossing paths at 90° to oneanother and seen laser/light momentarily pass between them at their closest point. I couldn't believe it at first, that I could see this phenomena(whatever it was) from the earth!
I just find it amazing how they are going to use lasers, but i wonder if having to find the next satellite 🛰️ before it beams will bottle neck the speed? Or it would be a constant stream of data without interruption?
The number of lasers on each satellite will always be small: initially two, maybe later four. They will be steered toward specific nearby satellites, initially the one ahead and the one behind in the same orbit. A second pair may be steered toward satellites in adjacent orbits, maybe switching quickly from one to another (in a ms or two) as they come into range on a scale of multiple seconds. The main use for lasers is, initially, to get traffic from a satellite not in range of a ground station, such as over a pole or out in the ocean, to one that is in range. They will dump traffic to ground stations as quickly as possible to minimize load on the sat-to-sat mesh. Later, the orbital mesh _might_ enable Starlink to get along with fewer ground stations. It is just possible Starlink will also start putting lasers in ground stations, enabling them to bypass radio transmission on that link, although weather would frequently but temporarily take out such a link, most places.
Wow, I went to sleep watching this video I woke up and you were still talking ... Just kidding GREAT video . I remember you saying lasers were coming . Love the chalk board , did you knock the dust out of the erasers ?
I game on my starlink all the time. This could be a game changer. I sit at about 50ms of ping on most of my games. To see that come down to even 20ms would be amazing.
I hope you're right about the elimination of the ground stations. I think that is what is keeping east Texas out of the available category. I would like to go back to the regular monthly price instead of the congested one. Keep on keepin' on, man!
It is almost certain to get some kind of NOC in space, eventually, but the cost of lifting it, and maintaining it, and the power requirements will limit the implementation, but it will come. Also, you talk about eliminating ground stations, there will always be a need to communicate with the terrestrial internet, that is done via connections to existing fiber networks. Lasers are great in the vaccuum of space, or through a glass fiber, but don't work nearly as well through an atmosphere. The connection to the terrestrial internet will always be via a radio, which requires a dish and a connection via a ground station to convert from radio to fiber or terrestrial based radio frequency, like cellular. The laser interconnects can go up to 100Mbps/ea, but terrestrial fiber goes at up to and over 100Gbps, and will be at 400Gbps soon in many areas, per strand.
For those who complain, keep in mind those are your viewers and perhaps they have a point to make . As a content creator I think it’s equally as important to provide badly content viewers will not complain about as well as content made the way you prefer…..Certainly apples and oranges but I’ve seen gaming channels die because the content creator played games they preferred be what the viewers preferred
One NO center might be better able to be neutralized should it come to that, than many diffuse terrestrial 23:20 centers. Just saying. Network speed/efficiency and network security in case of conflict are both important factors to consider.
Love this stuff... member here, you deserve more. Your subs will rocket just like the number of Starlink users. Keep it up... but do finish your bathroom.
IDK 🤔...The big caveat with the lasers is they are only faster if they communicate over large distances. So if the Laser routs directly from a sat over California to a sat over NY yes it will be faster, but if the data routs through say 8 or 10 sats to get from California to NY it may not be. Because each sat will add latency as it receives and retransmits the laser.... Given the sats line of sight it's possible you could maybe cross the Atlantic in 2 or 3 steps. The big questions are, are the lasers capable of being aimed that accurately, are they powerful enough and collimated well enough to send a signal that far...To all those questions I'd say probably/maybe.
one point, how do you maintain capability if the sun does not behave and causes outages ? if all your eggs are in the one proverbial basket, fibre as a earth bound backup?
This I felt was always the plan, when New York to Ireland fiber optic was installed it shaved 1ms of latency from trading and made the company billions. I think I saw StarLink can shave 3ms off and would be the fastest London to New York communication for stock exchanges.
Going to make a huge difference for people in areas that have bad routing like Alberta Canada as soon as you route through Edmonton Alberta, ping times just fly out the window and they often have issues on the route to where your going. I'm already seeing these kinds of benefits just from it ground stationing from Seattle having lasers extending that further and faster will really make a huge difference in minimizing overhead point to point. . This is the future.
JC is excited... a great channel and one of the best on RUclips! I really enjoy the professionalism of the content. I did take your advice and installed Omada with 4 AC to create mesh in the yard - a game changer for sure...I recommend anyone to bypass the Starlink router and do your own...I gained a good bit of speed improvement, mostly reliability so devices are not dropped.
Your math is wrong. If you have data go from your boat to Sat A to Sat B to Sat C to Sat D to a ground station, each of those three inter-satellite laser links may be 100gbps, but you can't add them together to get a throughput of 300gbps. They are serial not parallel. The throughput from the first satellite to the last satellite in the chain is still 100mbps. Of course, it's a mesh so there may be some parallelism used, but the main point still stays the same.
NOC in space would be a literally parallel internet outside the jurisdiction of anyone/everyone. The weekness will be the FCC's of each country. The up/down spectrum will be the weak link
Nice!! So cool to hear about those lasers finally. I've been hoping to hear more information about those for quite a while now! Well those and that mini dish.... :) REALLY hoping for lower latency to any server around the globe with the addition of these lasers once they come online. From what I understand it could DRASTICALLY lower latency even for terrestrial connections across oceans too. I'm primarily interested in that for lower latency gaming as all the old games I like have only a few fans from all different countries.
I was right! After speculation for over a year, recently launched brand new advanced Starlink satellite lasers will change everything!

The most significant fact about Starlink lasers, commercially, is that now they can get securities market price and transaction data across oceans (e.g. between New York and London or Hamburg) several milliseconds ahead of the same data on existing fiber. (This, BTW, has nothing to do with bandwidth.) Any investment bank / hedge fund with exclusive access to such data can rake in extra $billlions, so if SpaceX is not metering out access to that capability, or taking advantage exclusively themselves, they are walking away from $billions.
There are also military applications for such latency benefits, so the US military is in the middle of constructing its own low-earth constellation. One such application is piloting remote-control aircraft from a desk in the Pentagon.
Ground stations will not be going away, at all. _All_ traffic between literally anybody without a Starlink terminal and communicating with somebody who is on a Starlink terminal will be going through a ground station, forever. The fraction of traffic going directly between users both on Starlink terminals will be negligible. Placing a network operations center in orbit would offer Starlink no benefit, so is unlikely to happen: latency between a NOC and Starlink satellites is unimportant.
Watching every minute and appreciating the quality of every video
I think you have a masculinity problem because you talk and sound like a 10 year old girl who is all exited about everything they say out loud .
I love how you "take the time" to explain everything so precisely!!! Keep doing what you're doing!!
I thought so. Speaking with my wife in Tokyo from upper Michigan over ip has been simply amazing quality with none of the the delays where we talk over each other.
Fantastic!
I appreciate how well you explain things. From a teacher's standpoint, you do a great job. Thank you for all your hard work.
Wow. That means a lot.
Keep doing what you do man. Short or long, your videos are some of the most informative videos out there. I appreciate your time and explanations with the content you put out. Don’t get caught up worrying about the few that just want the microwaveable version or quick answers. Those folks are not your target audience so don’t bother explaining why the vids need to be “long” so they don’t get their feelings hurt.
So very kind.
I always watch you stuff beginning to end. Your content is great please keep up the good work.
I appreciate that!
Hi JC. Love your channel. I'm a military satellite communications engineer. The math where you multiply the # of lasers by the speed of each laser, isn't how it works. Basically you want to compare the throughput of the system with and without lasers. You have the concept basically correct in that the "w/ laser" network transfers data faster than without.
Without, you go from your house in Miami to a satellite, back down to ground station, terrestrially to a POP, then at the "speed of the internet" to the server you want to connect with, let's say in Los Angeles. Then in reverse. The satellite to satellite laser comms basically replaces the cross country terrestrial "internet" leg of journey. So basically, you simply compare the speed of terrestrial internet to the speed of the laser comms. With lasers, the journey would be from your house in Miami, up to Starlink satellite, THEN, at LASER COMM SPEEDS, to a Starlink satellite over LA, then down to ground station of POP, then via internet to the server in LA. If the laser comms is at 100 Gbps, you would compare that to the "speed of the internet" in the "w/out laser" scenario.
The throughput in the "w/ laser" scenario is more, and the speed is more, but you don't multiply EACH laser link. The fastest you will be able to achieve is the 100 Gbps inherent in the laser comms speed.
When talking about data comms, you also need to pay particular attention to the speed AND the throughput. A good anology is trucks on the interstate. Trucks carry your data from your house to mine. If the road has 4 lanes, and the trucks and drive 100 mph, and each truck carries 1 Byte of data, you get 4 Bytes at 100 mph. But if you have 1 lane but the trucks drive at 1,000 mph, you get a lot more data faster. Lasers are like 1,000 mph 18 wheelers on a 1 lane road.
I'm not sure what exactly was the big secret… Everyone has known about this for over a year. Star link has "space lasers" T-shirts for the employees that they've been wearing around publicly for over a year.
When you mentioned NOCs in space, it sparked this idea - How about a distributed database and blockchain network in space? Important global information could be permanently stored and retrieved by anyone - regardless of what any individual nation state or corporation tried to do to "block the internet". Even better, once subnets of satellites begin orbiting the moon and Mars, the same data could be consistently replicated to and from those places as well.
I like it!
Wht will be the basic set up for starlink house three floors, top floor terrace, with full open sky. Appreciate your support in put. Thnaks. Jc
I would have an AP on each floor and even consider an OUTDOOR AP outside.
You will still need ground station as redundant connections. This allows to connect older slower internet systems to be online.
Theoretically if they can use laser comms all the way from New York to London then the route is actually faster than the fibre-optic cable connection which is worth a lot to traders (billions).
The really amazing thing about Starlink laser links is that it enables city-grade internet everywhere on the planet, which is a massive game changer. Hapag-Lloyd is rolling out Starlink to all their 258 massive container ships, for crew communications and vital operational comms, and it won't be long before this is compulsory for all modern shipping and fishing fleets (for compliance reasons as well as operational and crew). A really cool aspect for low density populations like NZ, Australia, mid-ocean etc.) is that Starlink is sized for the high density northern hemisphere, which means low density areas get consistently extreme performance.
Looks like a great future for starlink! I’m getting my equipment Monday 😃
Congrats!! That is really great!
Could you break down the whole starlink more even though I have it and watched about all of your videos lol... if possible use an Etch-A-Sketch ... Love your videos... people will complain about anything.. thank you always for the info you provide on SL.
😂 I will have to find my kids OLD Etch-A-Sketch.
The issue will still be the latency in the up/down from satellite to ground. The latency will not be able to be as fast as fiber. Yes the speed in orbit will be faster, but it’ll be throttle still beaming up and down.
Awesome update and excellent content. If I'm interpreting your math correctly eliminating ground stations cuts out 20% or so of the latency producing steps. Then using lasers reduces further cuts latency by 40%.
Every second the data can stay in orbit will certainly help reduce latency for sure.. Great points, Spencer!
The biggest reason for this upgrade that you missed is that if you don’t have the lasers, you can only communicate if the satellite can see you AND a ground station. But now as long as you can see any satellite with a laser and that satellite can see more, and so on, until it hits one that can see a ground station, you are good. Realistically this allows you to cover the entire world with theoretically only one ground station. Obviously would still have more, but now if the ground station for Central America goes down because of a storm or for maintenance, the laser links just let you connect to a different station.
You spent the first 2 minutes talking about how you don't get to the point and people get upset at how long it takes you to get to the point. This is literally the first video I've ever seen from you and I am leaving now good job bud you're a genius!
I'm about little kid level excited this will be a huge break through technologically being setup
🛰️🚀
Thank you for your Starlink info videos, as a retired Navy Radioman I used alot of HF to transmit message traffic, for long distances ie Med Sea to Red Sea to hear 'Lasers' is AWESOME. THANK YOU for your explanation. PEACE
I think there will be more than 2 lasers per satellite to hit that 8K target as I doubt the oldest satellites will have lasers
You could very well be right!
Agreed, it wouldn’t make sense to spend the significant sums of money to launch the satellites with non-redundant link capabilities (lasers in this case), I’d expect there are also cold standby lasers, and that any single satellite communicates with several others, thus requiring more than 2 lasers. Given that some of the Starlink capabilities are used by the US military, would be very unsurprising that there are aspects not made known to the public.
Tech days and long videos are my favorite! Never change! ❤
Light is just very high radio frequency. The visible window is between 300-750 THz (300,000 to 750,000 GHz). The higher the frequency (which produces shorter wavelength) the narrower the beam-width for a given antenna size. RF and Light travel at the speed of C in free space. Both slow down in air and slower still in water (RF is attenuated rather quickly in water). This is why fiber (laser based) is so much slower than laser in space (glass is much more dense). [Besides trying to hook two satellites together via fiber is an exercise in futility.] The main advantage of laser over lower frequency RF is the beam-width advantage of the laser. It is a much smaller "spot" for laser (making it harder to aim) but preserves the power density. At 14 GHz with a 1 meter dish the RF beam-width is 1.25 degrees. So at 1,000 miles (presumed distance between satellites) the half-power beam-width is almost 22 miles side. Even with the curvature of the earth and LEO, the possibility another satellite would be illuminated is fairly high.
The laser though has a much narrower beam-width at .0716 degrees (presuming the laser exit hole is 1mm and not 1m as for the dish). At that same 1000 miles the half-power beam-width is 1.25 miles. Much harder to aim but more likely to illuminate only the target satellite. The power in the signal is spread over a much smaller area meaning the receiver will get a much higher percentage (power falls over at the square of the distance).
BTW, hams are licensed for any frequency over 300 GHz
I don’t see ground stations going away but their traffic being reduced when communicating with other Starlink clients
I doubt ground stations will be eliminated. Thanks to them, satellites can connect to the internet.
Fiber optic cables of course use lasers as well, but the light has to travel through the medium of glass, which slows it down. It also has to pass through multiple repeater stations to get to its destination if travelling any significant distance. Depending on the laser used, between multiplexing and using various frequencies of light, fiber might be able to transmit *more* data/sec but it will be slower. Having said that, there are quite possibly frequencies that cannot be used in fiber that can be used when just passing through “space”. Technically there is still a very sparse amount of atmosphere present at the altitude that Starlink orbits at, but likely presents negligible effects on the beam, especially beam dispersion.
🚀
thank you so much for all that you present for us ❤️ really it's very hard for you. I like them. I always follow your videos, especially related to Starlink .. Thank you so much .. best wishes for you from Iraq ❤
Many blessings to you and your family!
Are these lasers a visible wave length of light, or infrared or something else. So what if all satellites with a line of sight were to transmit their laser to one focal point on land?? Would that create enough energy to start a fire?
My guess is that each link uses 2 lasers: Transmit and confirm of the reception. for error correction. In this case your total network transfer capacity is half of what you calculated.
I’m wondering if SpaceX can shut down particular areas of say, certain Continents? Like do we really want our adversaries being able to use this technology against us?
Yes, obviously, some countries have banned it anyway.
@@fredbloggs5902or say they do but militarily they will attempt to use it. Like a burglar with a crowbar, but then the business has the key hidden under the Welcome mat.
I am guessing it is location based and is encrypted.
The true fix to to calm ppl about getting to the point or not is to provide timestamps I just watch the whole thing though
Great Venting! You doing a great job J. and I subscribe to your channel because of all the content. Thanks for all the work you put into your content and channel. I'm thrilled about it and hoping for more speed up and down.
Thanks for the sub and being here!!
Great info! Always figured something like this was going to happen. But how are these going to be protected from enemies trying to stop this? Again great stuff and able to understand all of it. You the man!😊
I want to see a few large NOC in space that do a lot of the security while in space. Makes sense to me. We will see.
Lazers explain why the autoglass melts and the trees only dies is the fires that are happening all over the country. Cheers
Lost me Joy.
What will be the performance for the lasers through rain/smoke? What will be the impact on latency…still faster than fiber, maybe an offset. Awesome video again!
At 550KM there is no rain or smoke. It's simply the VACUUM of space.
Always good solid information. Thanks Pal
Thanks so much.
Too long of a video? Nope. It was just over 10 minutes for me and I enjoyed every minute of it and am better informed because of it. Why? because you speak so clearly and accurately that I can listen at 2X speed and not miss a detail of your excellent presentation. Thank You! Subscribed.
It's not the subject of that video but I'd like to know something, maybe it don't apply to starlink, but it's a shared connexion , right ?
What is the ratio ? I tried to find that information anywhere I could but I didn't find it ?
Great presentation! The pace was FINE! You ae reaching a wide audience! And thanks!! Oh yeah, how is the bathroom?? LOL PEW PEW!! Love it!
😂 the bathroom was pushed back because I hurt myself. 😔
You could cache data in the satellites themselves so they can respond faster.
100% exactly. Just like ISPs do today.
What you're really alluding to is - Verizon, T-Mobile, AT&T, Google Fi, Mint Mobile - will go the way of the type setting "Linotype" machine when the Macintosh 128K nicknamed the "thin Mac" industry disruptor was introduced in 1984 - "Because 1984 won't be like 1984"
I remember using a Vari-Type type setter when I first start at a magazine doing paste up and layout. 😂
I personally like all your contents thou i might not comment a lot but honestly i hear really commend you for taking the time out to research so that we can be enlightened and aware of whats going on out there. personally i dont mind how long your videos are cause they are very interesting. so thanks for all the hard work that you have put into all your contents. if you need an hour to get you information out then so be it. your viewer from the small Island of Jamaica
I appreciate that! Truly! Many blessings...
What a perfect tool for the A.C. to utilize, wow!!
Thank you for being here!
Absolutely sir! Very valuable info that everyone needs to see, on many levels.@@jcristina
12:43 This really was a very informative video. Also very detailed, good video 👍. Also I also understand what you’re explaining. A router with access points was a good example. It is definitely going to speed up, This will help latency so much
Awesome, thank you! Appreciate you being here!
@@jcristina no prob!
so, the ground stations don't "go away", they get reduced/combined with pops. The biggest hurdle for latency has got to be the home satellite dish, which isn't changing with the laser mesh network is it? Also, wouldn't it make sense to incorporate the router functions directly into the new satellites?
I’m guessing a.
Rattle on I can fast forward and cut out the crap parts. Slice and dice is soooo nice!
There you go!!! Play back at 1.5x or skip around as needed.
You are my most watched content. You're greatly appreciated. Also I sent you an email telling you about what I found d out about starlink mesh routers. Thank you for what you do
Thank you. You’re so very kind. I will check email tomorrow. Blessings.
i had a weird spike one late night in ph to over 800mbps and back in morning to 130 to 200 as we a distance from from north satilite. what was that?
I aimed a laser pointer at the first statilnk sats, one of them flashed a laser back at me! I saw it hit the clouds above me!
How could you see the satellite if there was clouds above you? fos
If you think the video does not come fast enough - turn up the speed for the video to 1.25, 1.5, 1.75 or 2.0 X speed through the gear menu on the video interface. I do that for many videos. I find it easy to listen to most videos at 1.5X speed without loosing any information..,
Great point.
How about the rounding at this around 500km above us in space? I mean lasers can not really shoot (piew piew) around the corner, can they ? So they should be relative close to each other right ?
Thanks for the video by the way ...
Yes. Straight lines. There are currently 4500 operational and at 550KM there is no issue keep the connection, it’s my understanding.
Very Very cool, this is Sci-Fi coming to real life, I will bet that the pops will be laser soon for up and down link
Absolutely.
As someone working in the telco industry this is my comment: You still have to enter the terrestrial internet at some point, and that point should be as close to the terrestrial destination as possible. So there still will have to be many terrestrial POPs across the globe, so there is really no point of doing NOC in LEO.
Thanks for the info on dns configuration it helps & thank you for all your advice!
Base stations are necessary for the following reasons. When using the Internet in Europe, I use many websites with servers in Europe. If the base stations remained only in the USA (these satellites have to transmit data somewhere), the signal would be transmitted from Europe 8,000 km to the USA via a network of lasers (at best 26 ms because the speed of light is 300 km/ms). Then these packets would return via the terrestrial network from the USA to Europe. From my country I have 100-150 ms to servers in the US so the delay would be huge. Therefore, the base stations must remain regional, otherwise the delay will increase due to international routing, and the laser link system will be used over the oceans.
Just don't know, Its still getting slower. Wish existing customer speeds would improve.
I watch RUclips channels mostly for long form content. If I wanted it condensed to 1 minute I'd watch some shorts. Just ditched my dual bonded CenturyLink DSL and switched to starlink and your content helped me make that informed decision!
Thank you for that.
Thanks for information. Been a Starlink customer in Flagstaff for a couple years now.
Likewise. Thank you for being here.
Haha, I love picking on the dorks who don't know how to operate the basic features of a youtube video to skip ahead, adjust the volume, don't recommend for click bait channels, etc.. That being said, adding a couple chapter markers (if for some reason you ever feel bad for them) are very useful.
Joe: I think you missed a detail. The space resident Starlink mesh MUST connect to the terrestrial "backbone fiber" preferably at high bandwidth fiber locations SOMEHOW.
That's why the Ghz microwave antennae are on each satellite to access customer ground terminals AND ground stations which may be close to a POP. I don;t know how many phased array antenna are on each satellite. Some Starlink satellites need to access a ground station near a POP. Starlink mesh will still need "Terabits" of microwave links to the ground. The POPs will certainly be encrusted with microwave "mushroom" antennae. Ground station relay points should disappear . POPs won't.
Lasers don't do well in the atmosphere which is why microwaves are used. Microwaves DO get attenuated by rain, snow... especially in the higher Ghz range. Happens to me with my Starlink V2 "candybar.
The satellite lasers may be fairly cheap in large quantities while ground stations aren't. I can't wait to see how much the Starlink network performance increases!
You always want a backup option if something takes out satellites. Solar storms, polar change, anti-satellites whatever. Always have a backup!
Absolutely. Just like a ground connection a satellite is a great backup.
NOCs in space is an obvious evolution of Skyne... I mean Starlink. I can also foresee having parts of the internet mirrored on satellites.
Did you just say 10 ms latency ways better than 7 ms latency?
110% Internet 2.0 in LEO
What you provide is great its ok to vent.
I'm the least technically sharp person you'll ever meet. So I appreciate simple explanations for these complex topics.
Blessings.
Dude, you just do a REALLY NICE job of explaining stuff of a highly technical nature - I appreciate you!
That really means a lot. Thank you.
I've watched two different starlink "constellations" apparently crossing paths at 90° to oneanother and seen laser/light momentarily pass between them at their closest point. I couldn't believe it at first, that I could see this phenomena(whatever it was) from the earth!
I’ve never heard of that before.
I just find it amazing how they are going to use lasers, but i wonder if having to find the next satellite 🛰️ before it beams will bottle neck the speed? Or it would be a constant stream of data without interruption?
I think they are all LOCKED IN to each.
The number of lasers on each satellite will always be small: initially two, maybe later four. They will be steered toward specific nearby satellites, initially the one ahead and the one behind in the same orbit. A second pair may be steered toward satellites in adjacent orbits, maybe switching quickly from one to another (in a ms or two) as they come into range on a scale of multiple seconds.
The main use for lasers is, initially, to get traffic from a satellite not in range of a ground station, such as over a pole or out in the ocean, to one that is in range. They will dump traffic to ground stations as quickly as possible to minimize load on the sat-to-sat mesh. Later, the orbital mesh _might_ enable Starlink to get along with fewer ground stations. It is just possible Starlink will also start putting lasers in ground stations, enabling them to bypass radio transmission on that link, although weather would frequently but temporarily take out such a link, most places.
Man don’t matter to the island people right here if long or short. You’re doing an awesome job, keep doing what you’re doing
Those 'knocks' might come real soon if the Government doesn't slow down Starships development.
We will soon see.
Wow, I went to sleep watching this video I woke up and you were still talking ... Just kidding GREAT video . I remember you saying lasers were coming . Love the chalk board , did you knock the dust out of the erasers ?
lol
😴 Thanks! :)
I game on my starlink all the time. This could be a game changer. I sit at about 50ms of ping on most of my games. To see that come down to even 20ms would be amazing.
110% fact
Video starts at 3:17
I hope you're right about the elimination of the ground stations. I think that is what is keeping east Texas out of the available category. I would like to go back to the regular monthly price instead of the congested one.
Keep on keepin' on, man!
It is almost certain to get some kind of NOC in space, eventually, but the cost of lifting it, and maintaining it, and the power requirements will limit the implementation, but it will come. Also, you talk about eliminating ground stations, there will always be a need to communicate with the terrestrial internet, that is done via connections to existing fiber networks. Lasers are great in the vaccuum of space, or through a glass fiber, but don't work nearly as well through an atmosphere. The connection to the terrestrial internet will always be via a radio, which requires a dish and a connection via a ground station to convert from radio to fiber or terrestrial based radio frequency, like cellular. The laser interconnects can go up to 100Mbps/ea, but terrestrial fiber goes at up to and over 100Gbps, and will be at 400Gbps soon in many areas, per strand.
I’m thinking more of a cache. Like what ISPs use today to FAKE their data rates.
Where do you think the next Gen ground station in Marshall, TX fits in? There are others like it too.
Thank you. If the video is too long I just skip it. But I don't. Never too long.
Yes
Way to GO JO 😎
I said ground stations in Canada would be obsolete thanks to Lasers
#facts Thanks Glen for all you do!
Then why is my starlink getting slower and slower?
it was usually 250ish Mbps now its almost always 70Mbps
For those who complain, keep in mind those are your viewers and perhaps they have a point to make .
As a content creator I think it’s equally as important to provide badly content viewers will not complain about as well as content made the way you prefer…..Certainly apples and oranges but I’ve seen gaming channels die because the content creator played games they preferred be what the viewers preferred
110% I try to provide what the majority is looking for and I am have legitimate interest in.
One NO center might be better able to be neutralized should it come to that, than many diffuse terrestrial 23:20 centers. Just saying. Network speed/efficiency and network security in case of conflict are both important factors to consider.
Why... My favorite word. My wife says I use it way too much. Thanks for the "why".
😂 me too
Love this stuff... member here, you deserve more. Your subs will rocket just like the number of Starlink users. Keep it up... but do finish your bathroom.
Thanks so much. Many blessings.
Very informative! Not too long, great content!! Thanks for the information. Your content is very concise. Makes everything clearer.
Thank you. 🚀
What does this mean? It means this battle star is fully operational now.
:)
I remember exactly when you predicted satellite to satellite without ground stations. You get a gold star from me!
Thank you. It was more than a year ago now. Kinda crazy. So glad it’s really starting blast off. So to speak.
Enjoyed it very much.. Thank you
So glad!🚀🚀
Very interesting. Thanks so much for great content and information!
Appreciate you being here b
IDK 🤔...The big caveat with the lasers is they are only faster if they communicate over large distances. So if the Laser routs directly from a sat over California to a sat over NY yes it will be faster, but if the data routs through say 8 or 10 sats to get from California to NY it may not be. Because each sat will add latency as it receives and retransmits the laser.... Given the sats line of sight it's possible you could maybe cross the Atlantic in 2 or 3 steps. The big questions are, are the lasers capable of being aimed that accurately, are they powerful enough and collimated well enough to send a signal that far...To all those questions I'd say probably/maybe.
👍🏻🚀
one point, how do you maintain capability if the sun does not behave and causes outages ?
if all your eggs are in the one proverbial basket, fibre as a earth bound backup?
Yes. Terrestrial and non-terrestrial is a good way to go.
love your channel. I'm using Starlink to watch you near Peterborugh Ontario Canada. Keep up the good work. Thank you
Awesome! Thank you!
the random disconnections the downtimes? will this eliminate the DOWNTIMES!??????
It will in time.
Thanjks for the tech review.
Thank you 👍🏾👍🏾
This I felt was always the plan, when New York to Ireland fiber optic was installed it shaved 1ms of latency from trading and made the company billions. I think I saw StarLink can shave 3ms off and would be the fastest London to New York communication for stock exchanges.
Going to make a huge difference for people in areas that have bad routing like Alberta Canada as soon as you route through Edmonton Alberta, ping times just fly out the window and they often have issues on the route to where your going.
I'm already seeing these kinds of benefits just from it ground stationing from Seattle having lasers extending that further and faster will really make a huge difference in minimizing overhead point to point. .
This is the future.
Absolutely. People that have ground stations that are far away will see a major improvement soon.
JC is excited... a great channel and one of the best on RUclips! I really enjoy the professionalism of the content. I did take your advice and installed Omada with 4 AC to create mesh in the yard - a game changer for sure...I recommend anyone to bypass the Starlink router and do your own...I gained a good bit of speed improvement, mostly reliability so devices are not dropped.
🚀😱
Q With all this Starlink capability, why is there very little coverage in southeast USA? Thanks for your keeping us informed.
Your math is wrong. If you have data go from your boat to Sat A to Sat B to Sat C to Sat D to a ground station, each of those three inter-satellite laser links may be 100gbps, but you can't add them together to get a throughput of 300gbps. They are serial not parallel. The throughput from the first satellite to the last satellite in the chain is still 100mbps. Of course, it's a mesh so there may be some parallelism used, but the main point still stays the same.
Thank you.
NOC in space would be a literally parallel internet outside the jurisdiction of anyone/everyone. The weekness will be the FCC's of each country. The up/down spectrum will be the weak link
Nice!! So cool to hear about those lasers finally. I've been hoping to hear more information about those for quite a while now! Well those and that mini dish.... :)
REALLY hoping for lower latency to any server around the globe with the addition of these lasers once they come online. From what I understand it could DRASTICALLY lower latency even for terrestrial connections across oceans too. I'm primarily interested in that for lower latency gaming as all the old games I like have only a few fans from all different countries.
Exciting for sure!
