JC:
Off topic a little.
There are a lot of small satellites companies touting their ability to making smaller, more cost effective satellites capable of doing imaging of the earth-forest fires, methane gas emissions, pollution, etc. My feeling is space ex rules the sky and could easily implement this technology. I know this is not your field, but just wanted your views. Many thanks!
As you mentioned the higher frequency has a shorter wavelength and is absorbed more thus attenuating more but can carry more data. To compensate for this attenuation you need more power and bigger dish/antennas to focus all the signal energy to the destination (satellite).
The lower bands make more sense for links to and from home users where you don't want a big antenna.
The crazy high frequencies are better suited for the base station uplink/downlink(Multiple terminal data streams combined) where you can install huge antennas for the base stations to compensate for the attenuation of the signal and use more power.
Another interesting fact is that a big antenna/dish works in both directions, it focuses the transmitted energy and it listens like big ears. Obviously, for the strongest possible link, you want big antennas on both sides.
If you really want to go down the rabbit hole of RF/electromagnetic signals read up on Wifi-MIMO and spacial division multiplexing. In theory, a satellite can transmit to multiple users antennas on the same frequency at the same time as long as they are far enough apart, using its phased array to project/steer the volume of each data stream to the specific ground station. This would be equivalent to you speaking to two people at the same time by projecting each of the two sound waves at the specific person. Also works in the reverse direction where two(or more) people can talk to you at the same time but because the sound reaches you from slightly different directions your multiple ears/antennas can use the time-delay between the sounds reaching each of your ears/antennas to separate the two conversations/data streams.
@@pietersmit621 - thats good and interesting info bud. cheers :)
Without going to a different frequency, Starlink is very likely able to adjust the data rate downward when weather or anything else impedes their signal propagation. This kind of speed fallback is very common, and home users experienced a version of it on the old dialup modems: the 'bouncing' noises before settling down to just static was the modems on each end figuring out what the maximum useful speed was, until they agreed. Unlike Starlink, the old modems were not normally able to increase the speed afterward, if transmission conditions improved.
the old trick they used to do back in the 90's was this : they claimed these new high speeds of 2x, 4x, 6x or 8x etc but if you were smart you noticed that they throttled everybody's service WAY down and after you maxed out the new services, you'd get back to the same thing you used to have but your bill doubled.
Hopefully this won't increase our monthly cost.
doubtful..
Or result in caps.
While they have the Engineers to look at dual band ground antennas for the end user,it will be a feat. An example is Seatel antenna that can handle KU and C-Band. It requires a switching of LNBs. That means higher costs and larger antennas. C-Band is more reliable even in bad weather over a Ka or Ku. Ka and Ku will suffer in bad weather, so for home use, it might be a wash on the user end compared to the low earth antennas. Back haul, those have some advantages. I'm not a satellite expert, but use them in my work. We are using Starlink and a Ka system on our ships. Two separate systems. Sarlink at $1000, and a Seatel Ka at $30k or more. We have a KVH ka/ku receive antenna for DirecTv at $30k plus too. So I'm not sure if Starlink can make a dual antenna that is affordable for home users. If they can, Seatel, KVH, intellian, etc. will be hurting to compete.
after watching some of your videos I finally pulled the trigger, I got my kit today from bestbuy, I have it temporarily in the back yard, the set up was seamless, I have over 40 devices on my router, including 8 fullHD nest cameras, 3 PCs, phones, ipads etc, it is raining hard non stop, but I manage to get 270mbs down 40 up, I cant wait to do some testing after I mount it on the roof and clear skies.
Your intros are waaaaaaaaaaaaaaaaaaaaay to long. Get to it bro
Ugh yes. I just fast forward. Best YT channels have no intros.
Dude's gotta earn, so if you don't like his intros and ads, fast forward and send him a few bucks. Love the content and the tea Joe!
As always, great update and summary. For those that think SpaceX has hit a wall, let’s not forget All of the major hurdles they have encountered dating back to buying an ICBM shell from the Russians. This is just part of the iterative process. Sad it didn’t fully work this time, but it will. Patients grasshopper!!! Congrats SpaceX!
Before anyone responds, I know they didn’t end up buying the shell!
This is so awesome to watch! From a user to just a SpaceX fan. The tech being used is fantastic!
J...your getting close...i expect we will hear at some point ... I have heard they are working a hybrid frequency setup to be able to penetrate buildings, planes and such...Eventually imagine that mesh network servicing most of communications. I believe that T-mobile is a stepping stone ....he will be in learning mode before he fills the gap and will not need the Cell companies (never mind that the cell companies would slow down the pace of his innovation). I also believe he learned from IPOing Tesla ...that it caused him some headaches to say the least! I think he will keep SpaceX private for now...once he goes to a public traded company...that opens him up to monopoly laws. If he stays private he can put the cell providers out of business in the next decade or less.
Amazing
best youtube channel for these subjects... thanks a lot
Another greatly informative conversational piece of work!
I do agree a protocol should be in place for a hybrid system that will have high and low band systems on bored for the satellites to communicate with ground stations during those weather changes. However, I still do think that some sort of space station hub that might carry parts of information to transfer back to the end user maybe something else that can be added on.
I could be mistaken in my thought process with that but I do think carrying some information nearby that can almost instantaneously be provided to the end user instead of the distance that must be traveled to exchange information might be doable. Now would it be financially reasonable to do and efficient is the next question. I'm not sure but it is something I would look at and consider
Ask AI
I’ve noticed in the last week or so we’ve had much less dropouts and buffering in the evenings. When I check speeds I’m seeing 120-300mbps (was 40-200 prior to last week). Is this because of the new band or more satellites?
Okay towards the end here. I don't want to sound like a dummy... But. If a ship is in the vacuum of space and it is relatively still. Not considering its revolution around the Earth. If it ignites its engines what does a push against to move forward?.
Can you give us an update on the Tesla Pi Starlink Phone? It has been a year. Lots must be happening. I want mine now, please!
I just had to add this comment. Today my son and I finally got our starlink satellite in its final position on a pole out in the middle of the yard and we ran the wire 75 ft underground in conduit to the house and up to the starlink router. It's more work than you would think. But it's worth it.
i also finished our isntallation today and it sure is much more work than you would think but the stability and speeeds are worth it
I’ll be ready to watch with my coffee in my hand. thanks for the video.
Oh ya!
Do you mean Gen 2 satellites or Gen 2 receivers?
Because I've gotten it from the very beginning.
Gen 2 Sats..
@@jcristina oh ok
Ok, first off, thank you, whoever that gave me a membership!
Today, Sedan Kansas, 218 down, 20 up 37ms. Not bad (better than Comcast cable!)!
glad have you with us brother :)
look for The Bomb for the membership.
them are great speeds. i'd be happy with 18 til i got a starlink lol..i only have junk trad sat options. 120 bux for a 700 ms ping....yuck lol
We're on the cusp of great things! - Thanks for informing us all Joe! - Cheers!

Like your way of thinking of hybrid band. Put on dish each one an when one isn't performing at peak speed it switches over an vice versus automatically.
yep! Would be cool
No good if starship doesn't fly
Tomorrow! 🍀
How are they producing so many satellites that size so quickly? They must have started making them a decade ago. I mean how many people know how to clean room assemble com satellites?
You don't need clean room for starlink satellite. The only thing that potentialy need clean room are the gyro and spacex source them from a supplier in a fully sealed module.
does this mean even more improvements to latency?
yep
Not much, about 1.3 millisecond.
This is awesome! However, spectrum also just got fiber out to my area in the middle of nowhere. So, as much as I’ve loved Starlink for the last few years, it looks like this is gonna do me no good! I can get the same speeds with much better upload and latency forless than half the price which makes it a no-brainer. But for those that stink, this is amazing to hear.
Personally it's been my experience that if you're somewhere where there is a so-called cable Monopoly. As in my case. I embraced competition. Not only to reduce the overcharge of the opposing company.... Okay I admit it. Screw them. I will gladly pay more for the same thing just to screw them. But I know starlink will improve. Not only the quality of my experience with them but the expansion of what they will provide. F Comcast Cable
Well, it should provide for a lot more data transmission in that band. Interesting that they made sure to remind them that Starlink won't "own" the band and may need to adjust when another satellite user also starts using the band. Just guessing, but I suspect that the FCC knows that the former SpaceX chief of satellite development, Rajeev Badyal, who is leading project Kuiper satellite systems, is looking to use that frequency band. If Starlink uses that band, they might very well get angry with the FCC, when a competitor also uses it,
It wouldn't be uncharacteristic of of Starlink/Musk, to over interpret an FCC approval as some indication of exclusivity. We've been there before!! It also seems consistent with Kuiper testing results and performance level predictions.
As for working around the weaknesses of the higher frequencies, I question that a "Hybrid" system would really be practical. Deliberately choosing to reduce throughput on demand seems like a disruptive approach to a solution. It might also take different antenna or at least very tunable antennas. And accommodating doppler shift may get more complex at changing frequencies. I think it may be more complicated than it sounds.
Weather related anomalies are essentially "local" conditions and a more robust and more distributed ground gateway network might get around the problem more effectively. Transmit power levels could help too, provided you didn't create interference for other users. (part of the FCC caveat in their approval). Increased power levels is one pretty easy counter measure to attenuation, but it could interfere with other users of the band.
Right now the experience level in that band use is low. Theory should be a good predictor of performance, but it isn't yet proven. I believe some testing results has gone into developing this band, but I think there are unknowns that only time will tell.
My Gen2 never lost communication during a Cat 4 Hurricane here in the Riviera Nayarit area near Puerto Vallarta México.
JC: Do you have any views on some of the small satellite companies? Many are touting the ability to create smaller sats at a substantially lower cost. These sats would be used for imaging of the earth...forest fires, methane gas, etc. My concern is that Space Ex could offer this technology with the snap of their fingers. They have the technology and money to do what they wish. They are the rulers of space. What are your thoughts?
Mr. Cristina, you are very much appreciated!
Not 4 times the people 4 times the bandwidth. It depends on what each person is doing of course. If I am downloading you are screwed lol.
I am certain that the Starlink engineers are very knowledgeable in dealing with the pitfalls of RF technology.
Wait? wasn't Gen 2.0 satellites that were waiting to be deployed once Starship became operational built with 10X capacity? I recall Elon stating this during his interview at Starbase with Tim Dodd.
I think this is part of that 10x figure. They originally said going from v1.5 to v2.0 would be a throughput increase of between 5x and 10x. If new spectrum approval was part of that prediction, it explains why the range was so large. They currently are launching V2 Minis which are only 4x faster than v1.5. Full v2.0 requires starship for the satellites to fit.
Named 2.0 and now we see the 2.0-minis going up.. The actual "2.0" full size that I call 2.0-maxi's may end up being called 3.0 when they actually are deployed via the Starship before the end of 2024.
60 ghz is impacted by rain and fog, 80 ghz does not
Gettung ready for 4X as many customers ?
Maybe!! We will see! 2.6 Million so far. 400K more with just 4 months.
i would imagine they already running your hybrid system.
They said the weather is not looking great for tomorrow in Texas. They will still try, but the weather on Friday looks better
The launch is scheduled a little bit too early, I wish they would push it back a bit.😔
When it is raining perhaps they divert to ground stations with good reception. They are all linked.
What they will do for your hybrid system is offer for sale a secondary antenna system along with an upgraded plan for the redundancy option.
Yet they can’t even get back to customer. Got a dish that’s not actitvated
Hope the weather doesn't mess up the launch.
Thanks for the update Joe!
🚀🚀🚀
FCC loves regulations, but the China satellites don't have to abide by the same rules.
The Chinese satellites will not be able to operate over the USA, as there will be no ground stations.
Oh ya.. Bunch of A$$ CLOWNS
@@jcristina lol
great video. thanks for the update.
I'm still getting ping over 50ms even tough I have great speed. Hopefully soon things will change for better!
The reduction of the orbit by 200 Km, reduces the signal's round trip by 400 Km. Look for about 1.3 millisecond improvement for that distance. I don't figure that many applications will benefit much from that small amount. Much of the latency is probably from the ground station to you and includes not only propagation time through whatever media the signal travels through but also through all of the electronics that is processing the signal in the satellite, the ground station and the equipment at your location.
Regarding your hybrid band idea, that wouldn't be necessary if the FCC would allow the satellites to increase their power output when beaming through bad weather. Broadcasting lower frequencies requires higher power anyway, so instead use higher power on higher frequencies as required.
For sat to ground they can just use larger and higher gain antenna.
Since when does FCC have jurisdiction of space?
For many many years when it involves U.S. companies and/or territory. It's the "Federal Communications Commission", not the "Federal Domestic Communications Commission". They regulate U.S. entities taking into account worldwide treaties per International Communications Regulations & Policy as do other countries for their territory and entities within their territory. So, the FCC regulates SpaceX launches and satellites, other countries regulate sale of services within their own territory. It isn't simple!
Wouldn't it be great if Starlinks had cameras? Real-time Google earth/ traffic, monitor job sites across the world,... so many use cases.
Hybrid antenna needs to be synchronised with the radio equipment on board satellite.
You need any beacon from weather observation to give the top signal for the switching on frequencies commutation on both sides (antenna and satellite)
Good idea by the way!
No need to observe the weather. This is how cellular has worked for years with carrier aggregation. You just use what works the best at the moment.
@@bobf.7238
Just to remind you that we are talking about space transmission, not the "horizontal" one: during the winter or heavy clouds period, E frequencies will be absorbed, so you need to know what weather you have between your ground station and the satellite to switch of frequency in order to avoid missing your transmission.
How can you do that if you don't know the weather condition?
Cellular works in a hybrid fashion. It's called carrier aggregation. In cellular, as many as six different frequencies between 600MHz and 30GHz. can be operated simultaneously by the phone. When weather and, believe it or not pine needles at 850MHz., block one or more frequencies, the phone just looks for data on any of the other frequencies and uses the one(s) that are getting through. There is no need to monitor the weather and no reason satellite communications can't operate similarly.
Horizontal transmission can often be harsher than low orbit space transmission which travels through the relatively thin, top to bottom, atmospheric weather where the rain and cloud cover sometimes, but not often, gets to 40,000 feet. Therefore, the vertical path through rain and cloud cover can, more often than not, be much shorter through weather from space than the horizontal path from a cell phone to a cell site, and back, which is usually wide spread at the surface where both transmitters are located. Add to this the fact that the cell phone handset is limited to just 0.6 of a Watt.
You can measure attenuation directly from signal power. No need for something complicated. If attenuation is high use low band if attenuation is low use high band.
By simply measuring the bit error rate on each frequency.@@consultantntic4056
