@@francisbalfour1243 AFAIK Bluetooth does do its own encrypting as well, based on that code you use when pairing devices with each other. Also listening to multiple frequencies at the same time is not something that is easy to do, you'd need quite expensive hardware if you want that amount of flexibility actually.
@@paulstelian97 even if it is, it would need to send it's key to the phone/earbuds. Which itself cannot be encrypted or the device wouldn't beable to access the key to decrypt later packets. So the key itself seems like it could be evesdropped

HTML, CSS, JS, HTTP, BGP, IP, just for the website part, not to mention SSD, CPU, GPU, HDMI, and USB on my pc, and that's just what I can think of off the top of my head with what limited info I have on the subject. What about all the other technologies needed to make the keyboard I'm typing on, the screen I'm staring at, and the computer processing it all? What about the manufacturing process itself? The servers at youtube HQ, and the technologies to communicate between them and your pc? I feel like if one person ever properly understood every single one of those technologies we use every minute, they'd go insane from all the information. It's the life's work of millions of people, all culminating in the single greatest thing we've ever created.

I still don't get why your channel doesn't receive 100x more audience, can't stress enough the quality of your work when it comes to vulgarize complex technology while going in depth through all the layers that makes them with such attention to details and accuracy in a limited time. Keep them coming, we'll be watching.
2021 June the 19th, l just discovered this channel. Instant subscribing and binge watching. I think there are lot of people who would be interested in this content but they just dont know it exists
I discovered your channel today. Your explanations (including the intentional repetition of information) and especially visualizations are superb - I mean really world-class IMHO. Channels like this are what make RUclips an amazing place and should be treasured. Faith in humanity restored!! Hope you never ever stop making these amazing videos
This video is unreasonably good. I dont think i've seen an educational video of any sorts with better analogies, explanations or better representation than this one. Big up, man!!!!
Can I just say that I appreciate the time you took the beginning to clear up some of the potential misconceptions that could have cropped up from your graphical abstraction of the data flow? So many people don't bother, which can lead to so many potential misunderstandings. So thank you for nipping that in the bud right the beginning.
@@BranchEducation Is there any chance you might do a series one day on how you obtain and process such amazing photogrammetry (assuming) models? It's insane the quality and I would love more knowledge on the BTS process on these videos in general!
@@TheOnlyDamien Yeah, in the near future I'll make a video on that. It will probably be on one of the shorter videos, because longer videos, well, just take too much time already.
@@BranchEducation That's perfectly understandable and I am excited to hear that it will happen in the future! I am fascinated with the process because I have never seen an educational channel have such amazingly detailed models for these breakdowns and I would love to know how it works! Thank you for all you do, you genuinely have no idea how many fields you have fascinated me on!
It is really mind blowing that this is all REALLY happening. Though, I do think it's important to remember that many of the discoveries and science done that makes this technology possible was built over generations and not all in a few years. Standing on the shoulders of giants as they say.
Giants of Industry now yet Packets were used by some Amateur Radio Operators (HAMS) in the 70's, least we forget the guy in his garage (or "shack") for developing the concept into reality. Maybe not all the credit, for hams had day jobs as engineers. They like to tinker. :)

No words can describe how fantastic every video you produce is. The production quality is astounding and the graphics and visualisations are absolutely perfect! Not to mention the excellent narration that thoroughly covers all aspects of the presentation. Looking forward to the next one!
@@BranchEducationI just discovered you and am enamored. I have to ask, are you or the narrator involved in the USCSB animated videos? It’s giving me the vibes. Also Merry Christmas
As an Electronics engineer graduating during Covid, these awesome animations have really taught me well. They really compensate for what I missed from having online lectures. This particular video has spanned across 4 subjects and 3 semesters. Though not complete syllabus, but it really helped me understand the basics. Thanks man!!
@@arande3 we are agents of entropy. life accelerates entropy by like 20x or something. Earth emits 20 photons for every 1 it receives from the Sun, but at 1/20th the energy each.
I already know a lot of this stuff, but these videos are so well made it's worth the watch even if the videos sometimes don't tell me anything new. The in-house 3d work really takes things to another level, and I have something I can show anyone who wants to learn, but doesn't want to hear my rambling excessive technical explanation.
I am speechless after seeing how amazingly "Bluetooth" technology is explained with such basic details with wonderful visualization. As a CSE grad I don't think this could be more easily explained
Saw this in my recommendations at 4AM (being drunk), and I tested the microwave oven part, it actually does hold up and it blew my god damn mind. At real close range it will send a photo. But around 2,5 metres it already felt real slow and placing the phone behind a wall at 3 metres killed the connection (image failed to send). Standing at 2,5+ metres while trying to send a photo, it always failed to make the connection. Phone out of the microwave oven had no issues sending a photo from another room through a wall (around 9 metres distance). The phones I used were Samsung Galaxy A50 as host and LG F70 as the receiver. Awesome video!!!
The chassis of the microwave is insulated from the ground and antenna of the phone. If the phone were ‘grounded’ to the microwave the shielding would be even better.
Mind blown. PS. I am an electronic engineer myself but still you give very complicated information in a simple understandable format. And its amazing to know how these work
After 4 minutes I can already tell this is a work a quality. Explaining all the basic knowledge necessary, an analogy welcome for people unfamiliar with the issue. Plus the different visualisations for diffenrent goals, all of this explained clearly, with a calm voice. I recognize there is a lot of work behind the scene. Even as a gratuated student in physics I feel I will learn a lot.
i just love learning about technology like this. i mean its mind boggling how complicated and amazing the technology we use every day is, and to most people it might as well just be magic. not many people really understand or care about how this stuff works.
Again another great video. Not only are they very nicely animated but you explain why things work from first principles, working from the very basics up. Always a pleasure to watch.
I love this! I’m a tech nerd (but not an engineer) and love to learn about this stuff but it’s hard to find videos that are informative, graphically simple, and keep the engineering part of the technology as simple as possible. I like the occasional humor too; funny but not distracting. Thank you!
I can't believe how I took Bluetooth for granted with me using it currently to listen to this and how complex it truly is which is a testament to human prowess. Great video in explaining something we often use to understand the complexities behind it.
these animated education of these complicated devices and technologies is much more than grateful... I really request to kindly give us more and more informative videos
Guys you are doing great job , I am an electronics engineer and couldn't have explained it better , the visualization were on point and also notes regarding the visualization!! I am grateful I came across this channel!
Bluetooth is a lot more impressive than I thought, I just knew it transmitted on frequencies. I never stopped to consider clogged channels or data being sent to the wrong device
At The Moment , I am learning English and also technology and science , This channel provides both of these requirements , hence I am grateful , thank you
Thousands of engineers, scientists, tech designers pouring months to years to make this technology, exctracting rare earth elements from all across the world that miners risk there lifes for everyday to get, all so i can watch some hentai without my family knowing. Human achievements never cease to amaze me.
@@jesusmontanez769 Bro that happens to me all the time! Usually I just roll with it and blast it from the speaker so I can hear it. After about 30 seconds I’ll be done and disconnect from the speaker. In case your wondering yes I do get weird stares from my family. Mostly my sister but my dad does it too so she and my mom are used to it.
The amount of dedication and work put into this video is just incredible. The research, making it understandable, the visuals...you are a gem. Thank you.
Your videos are of legendary quality and clarity. The concepts are incredibly complex, yet you manage to make it intuitive and almost simple to understand. The technologies are a true marvel of human intelligence and collaboration. However, making it understandable and jnspiring for such a broad audience is something that deserves enormojs respect. Thank you!
that analogy of building being like glass to radio waves instantly made me understand it in I way I never thought of. Was always slightly confusing to me!
Yeah! To add even more clarification to this, light is unique in that it is both a particle (photon) and a wave (photon travels in a wave-like pattern). Photons are absorbed by electrons in atoms which energize or excite them, and atoms in turn can release photons. This is the basis of why objects have color: we are seeing the photons that the atoms that make up these objects emit (even cooler, atoms emit the opposite of what they absorb, meaning a red flower absorbs green light). That’s why materials in walls and such absorb or block light waves from coming through, but radio waves and microwaves can pass through.
@ArisWertin People like you who spread knowledge for free deserve gratitude, so I thank you for writing this insightful comment, I am not a scientist nor a native English language speaker, I just have great love and interest in science, I truly appreciate reading comments like yours ! 👍
This is the first Branch Ed video I've seen. You are your own best advertisement - I bet a very large proportion of people like myself who run across your channel don't just walk on - I think they do what I'm about to - rub their hands and go and explore what other topics he's covered. Thank you Branch. I watched this with my 10 year old and thank you for his sake as well.
I love how those videos are both very accurate yet simple enough to keep everyone interested. I always thought that complexity was something to get perfectly right when explaining something, but you are making me rethink that.
Its insane how much value of information and principals is in creating and running one device and every year a bunch of very smart people push innovation further so we can sit on our couch and watch a video explaining one aspect of a random item in such a detail but simple.
*What are your thoughts* on longer-length videos? What is the longest video on RUclips that you have stuck around and watched in its entirety? Conversely what are your thoughts on breaking up a single 30 min video into 3x 10min videos?
I like it that your explanation doesn't rely on just words, those animations do play a big part to help us understand and make sure we're following! So provided that _those videos are long _*_but with animations,_* I'd say go for it. It's going to be more work for you tho.
I was always curious about precisely this but everything I came across was either too superficial to go over the visualisation of the fields and the existence of a protocol or so detailed that I could not understand. This video hits just the right point for me right now. The animations are awesome and the narrator is great. Thank you!
Out of all the videos on this channel, this one is my most favorite. I feel content now that it visually clarified so many concepts that I have pieced together over the years. Thank you Teddy for your amazing works.
I absolutely love that they used Hedwig Kiesler, and her home address, as the address (~7:50) for the example of the access codes/header. She was the one to discover/invent what would become bluetooth technology.
@@Ozninjaguy That specific part of the video they are discussing how Bluetooth prevents interference and encryption by frequency hopping. Something that Hedwig Kiesler (better known as Hollywood actress Hedy Lamarr) co developed during WW2. Jaap Haartsen used part of Hedwig's creation to allow for Bluetooth encryption. Google: Mother of Wifi Wifi also uses frequency hopping
I can’t say thank you enough. This is one of the best explanations of how Bluetooth works I’ve seen. I’m looking forward to more content from your channel. 🙂
I swear you guys read my mind and explain EVERY single time I get just slightly confused. The quality of these videos is truly on a completely different level 🔥🔥, like as if one's being personally taught. You guys wake up passion for engineering :)))
Wow, I wondered about how Bluetooth works for years. Great presentation. Many years ago, I recall hearing about how Bluetooth was a solution looking for a problem! It found one or several! 📡
I find the technology behind bluetooth to be just as mesmerizing as this channel's ability to explain such complex information to me. I'm grateful for both. Liked and subscribed!
Wow, the analogies are perfect, and you know exactly where beginners get confused! This is excellent teaching. Wish I had found this channel 2 years ago, but it's never too late! Thank you very much!
Were it not for that warning, I would not be replying now.

Simplified, a bluetooth device is a lightbulb emiting invisible light that can be seen by the other device, and certain characteristics of this light can be decoded into binary, which in turn is decoded into whatever you want. An earphone, for example, will get the information of how to vibrate in order to create the desired sounds.
now look at the mri and how we use giant nitrogen cooled magnets to exploit quantum propriety of water to take microscome-like picture of inside of the body and fmri that does the same but also use the one Fe atom of red bloodcell to estimate if it have oxygen on it and hence where the brain use the oxygene and hence witch area is active you and i probably don't understand (and by that i mean we could not make it) most technology past 1800-1900

I still don't get why your channel doesn't receive 100x more audience, can't stress enough the quality of your work when it comes to vulgarize complex technology while going in depth through all the layers that makes them with such attention to details and accuracy in a limited time.
Keep them coming, we'll be watching.
There is no doubt that people will come with time!
Did you mean visualize?
@@VaderHater1993 No, vulgarize as in "make less subtle or complex".
Cause it sounds too much like a robot and it can be boring.
2021 June the 19th, l just discovered this channel. Instant subscribing and binge watching.
I think there are lot of people who would be interested in this content but they just dont know it exists
The use of thoroughly depicting multiple different visualizations of the concept was a really fantastic idea. The animations are incredible
I discovered your channel today. Your explanations (including the intentional repetition of information) and especially visualizations are superb - I mean really world-class IMHO. Channels like this are what make RUclips an amazing place and should be treasured. Faith in humanity restored!! Hope you never ever stop making these amazing videos
Yeah the visualizations really are superb
I came hear to write the same comment but you stole my words
This video is unreasonably good. I dont think i've seen an educational video of any sorts with better analogies, explanations or better representation than this one. Big
up, man!!!!
Can I just say that I appreciate the time you took the beginning to clear up some of the potential misconceptions that could have cropped up from your graphical abstraction of the data flow? So many people don't bother, which can lead to so many potential misunderstandings.
So thank you for nipping that in the bud right the beginning.
Really impressed w this video tbh
I watched all your videos and i still can't believe how informative and well animated they are. Thank you!
Glad you like them!
@@BranchEducation thanks for your hard work
@@BranchEducation Is there any chance you might do a series one day on how you obtain and process such amazing photogrammetry (assuming) models? It's insane the quality and I would love more knowledge on the BTS process on these videos in general!
@@TheOnlyDamien Yeah, in the near future I'll make a video on that. It will probably be on one of the shorter videos, because longer videos, well, just take too much time already.
@@BranchEducation That's perfectly understandable and I am excited to hear that it will happen in the future! I am fascinated with the process because I have never seen an educational channel have such amazingly detailed models for these breakdowns and I would love to know how it works! Thank you for all you do, you genuinely have no idea how many fields you have fascinated me on!
It is really mind blowing that this is all REALLY happening. Though, I do think it's important to remember that many of the discoveries and science done that makes this technology possible was built over generations and not all in a few years. Standing on the shoulders of giants as they say.
Giants of Industry now yet Packets were used by some Amateur Radio Operators (HAMS) in the 70's, least we forget the guy in his garage (or "shack") for developing the concept into reality.
Maybe not all the credit, for hams had day jobs as engineers. They like to tinker. :)
Frequency hopping was invented by actress Hedy Lamarr and composer George Antheil.
"..and it's all REALLY there" --Feynman
@@galfisk U R making a joke, right? I missed getting the email, but thanks to Imran Q, the "Peters' Principal" (not Billy Peters) has availed the Hedy is someone to check out on DuckDuckGo.
Now Feynman had something to do with the BigBangTheory, and it was someone else who said "I've given up my search for Reality, now I'm looking for a good fantisey."
This cmnt will self destruct in one day. Good luck from Pennsylvania Mister Phelps.
It's astonishing how well such a complex topic can broken down into rather simple visual representations. Great job, and thank you!
No words can describe how fantastic every video you produce is. The production quality is astounding and the graphics and visualisations are absolutely perfect! Not to mention the excellent narration that thoroughly covers all aspects of the presentation. Looking forward to the next one!
Wow, thank you!

@@BranchEducation which applications do you used for animation
As an Electronics engineer graduating during Covid, these awesome animations have really taught me well. They really compensate for what I missed from having online lectures. This particular video has spanned across 4 subjects and 3 semesters. Though not complete syllabus, but it really helped me understand the basics. Thanks man!!

How did we go from banging rocks to this
Entropy definitely going the wrong way here
you bang rocks?
@@DavidG2P one definition of life I've heard is that which defies entropy
Its been a long time. there has been plenty of banging and rebellious youth trying to be cool. ILL MAKE BLUETOOTH FU BOOMER. etc.
@@arande3 we are agents of entropy. life accelerates entropy by like 20x or something. Earth emits 20 photons for every 1 it receives from the Sun, but at 1/20th the energy each.
I already know a lot of this stuff, but these videos are so well made it's worth the watch even if the videos sometimes don't tell me anything new. The in-house 3d work really takes things to another level, and I have something I can show anyone who wants to learn, but doesn't want to hear my rambling excessive technical explanation.
I am speechless after seeing how amazingly "Bluetooth" technology is explained with such basic details with wonderful visualization. As a CSE grad I don't think this could be more easily explained
I love how you're providing each and every minute detail without compromising with the ability to explain it so easily.
Saw this in my recommendations at 4AM (being drunk), and I tested the microwave oven part, it actually does hold up and it blew my god damn mind. At real close range it will send a photo. But around 2,5 metres it already felt real slow and placing the phone behind a wall at 3 metres killed the connection (image failed to send). Standing at 2,5+ metres while trying to send a photo, it always failed to make the connection. Phone out of the microwave oven had no issues sending a photo from another room through a wall (around 9 metres distance). The phones I used were Samsung Galaxy A50 as host and LG F70 as the receiver. Awesome video!!!
That's great to hear. I tested it with my microwave, but it's good to see it applies to others as well
The chassis of the microwave is insulated from the ground and antenna of the phone. If the phone were ‘grounded’ to the microwave the shielding would be even better.
@@Tadesan *bonded
I don't have microwave 😢😢
Mind blown.
PS. I am an electronic engineer myself but still you give very complicated information in a simple understandable format. And its amazing to know how these work
After 4 minutes I can already tell this is a work a quality. Explaining all the basic knowledge necessary, an analogy welcome for people unfamiliar with the issue. Plus the different visualisations for diffenrent goals, all of this explained clearly, with a calm voice.
I recognize there is a lot of work behind the scene.
Even as a gratuated student in physics I feel I will learn a lot.
Well stated. As someone that has learned primarily "on the job", I appreciate clear simple explanations of complex subjects.
Most excellent!
wow
i just love learning about technology like this. i mean its mind boggling how complicated and amazing the technology we use every day is, and to most people it might as well just be magic. not many people really understand or care about how this stuff works.

Truly excellent work.
Again another great video. Not only are they very nicely animated but you explain why things work from first principles, working from the very basics up.
Always a pleasure to watch.
I love this! I’m a tech nerd (but not an engineer) and love to learn about this stuff but it’s hard to find videos that are informative, graphically simple, and keep the engineering part of the technology as simple as possible. I like the occasional humor too; funny but not distracting. Thank you!
I can't believe how I took Bluetooth for granted with me using it currently to listen to this and how complex it truly is which is a testament to human prowess. Great video in explaining something we often use to understand the complexities behind it.
these animated education of these complicated devices and technologies is much more than grateful... I really request to kindly give us more and more informative videos
Every single video of you teaches me something new. Thank you ! Watched every single video of your chanal.
Thank you!
Guys you are doing great job , I am an electronics engineer and couldn't have explained it better , the visualization were on point and also notes regarding the visualization!!
I am grateful I came across this channel!
Bluetooth is a lot more impressive than I thought, I just knew it transmitted on frequencies. I never stopped to consider clogged channels or data being sent to the wrong device
i didnt even make it there and its fascinating early on even
It gets better when you start to read into how bluetooth actually transmits data, aka what the _protocol_ itself does.
At The Moment , I am learning English and also technology and science , This channel provides both of these requirements , hence I am grateful , thank you
bu tarz kanallarda türkleri görmek güzel.
Thousands of engineers, scientists, tech designers pouring months to years to make this technology, exctracting rare earth elements from all across the world that miners risk there lifes for everyday to get, all so i can watch some hentai without my family knowing.

11:34 "Don't sit so close to the TV or you'll ruin your eyesight!" -- Mom
The precision required and all the various pieces working together in harmony is awe inspiring.
that analogy of building being like glass to radio waves instantly made me understand it in I way I never thought of. Was always slightly confusing to me!
Yeah! To add even more clarification to this, light is unique in that it is both a particle (photon) and a wave (photon travels in a wave-like pattern). Photons are absorbed by electrons in atoms which energize or excite them, and atoms in turn can release photons. This is the basis of why objects have color: we are seeing the photons that the atoms that make up these objects emit (even cooler, atoms emit the opposite of what they absorb, meaning a red flower absorbs green light). That’s why materials in walls and such absorb or block light waves from coming through, but radio waves and microwaves can pass through.

@@Kaspersky360Prod Thank you! That means a lot; I want to be a science teacher and I love giving knowledge.
Your channel teaches better than universities! I haven't found any other RUclips channel that covers this content nearly as well!
This is the first Branch Ed video I've seen. You are your own best advertisement - I bet a very large proportion of people like myself who run across your channel don't just walk on - I think they do what I'm about to - rub their hands and go and explore what other topics he's covered. Thank you Branch. I watched this with my 10 year old and thank you for his sake as well.
I love how those videos are both very accurate yet simple enough to keep everyone interested. I always thought that complexity was something to get perfectly right when explaining something, but you are making me rethink that.
The idea of phase shifting just blew my mind! What an fantastic way to increase the speed of an output!
Exactly what I was thinking!!!
Its insane how much value of information and principals is in creating and running one device and every year a bunch of very smart people push innovation further so we can sit on our couch and watch a video explaining one aspect of a random item in such a detail but simple.
*What are your thoughts* on longer-length videos? What is the longest video on RUclips that you have stuck around and watched in its entirety? Conversely what are your thoughts on breaking up a single 30 min video into 3x 10min videos?
My longest is 3 hrs
Make it as long as you want it to be but with the animations
I like it that your explanation doesn't rely on just words, those animations do play a big part to help us understand and make sure we're following! So provided that _those videos are long _*_but with animations,_* I'd say go for it. It's going to be more work for you tho.
The captions on this video have a bunch of unnecessary hyphens
My max is around 3.5 hours
This is the only youtube video and channel that actually explains in detail what happens in a very easy to understand and digest way.
You are the top 1% of your field 👌

This video was very informative and knowledgeable. Being an electronics Engineer I'm very excited to visualise packets being transmitted.
I was always curious about precisely this but everything I came across was either too superficial to go over the visualisation of the fields and the existence of a protocol or so detailed that I could not understand.
This video hits just the right point for me right now. The animations are awesome and the narrator is great. Thank you!
Out of all the videos on this channel, this one is my most favorite.
I feel content now that it visually clarified so many concepts that I have pieced together over the years.
Thank you Teddy for your amazing works.
Nothing but my biggest respect for your perfect output on that Chanel. Thanks a lot.
Whoever made this video, thank you.
I absolutely love that they used Hedwig Kiesler, and her home address, as the address (~7:50) for the example of the access codes/header. She was the one to discover/invent what would become bluetooth technology.
Nope. Bluetooth was invented by Jaap Haartsen.
@@Ozninjaguy That specific part of the video they are discussing how Bluetooth prevents interference and encryption by frequency hopping. Something that Hedwig Kiesler (better known as Hollywood actress Hedy Lamarr) co developed during WW2.
Jaap Haartsen used part of Hedwig's creation to allow for Bluetooth encryption.
Google: Mother of Wifi
Wifi also uses frequency hopping

Wow, I wondered about how Bluetooth works for years. Great presentation. Many years ago, I recall hearing about how Bluetooth was a solution looking for a problem! It found one or several! 📡
I find the technology behind bluetooth to be just as mesmerizing as this channel's ability to explain such complex information to me. I'm grateful for both. Liked and subscribed!
Wow, the analogies are perfect, and you know exactly where beginners get confused! This is excellent teaching. Wish I had found this channel 2 years ago, but it's never too late! Thank you very much!
Speaker chuckling 😹 : 12:17 *"Do not turn your microwave"*

I died laughing.
Were it not for that warning, I would not be replying now.
Simplified, a bluetooth device is a lightbulb emiting invisible light that can be seen by the other device, and certain characteristics of this light can be decoded into binary, which in turn is decoded into whatever you want. An earphone, for example, will get the information of how to vibrate in order to create the desired sounds.
I've no words to describe how absolutely amazing this video is! This video and the Bluetooth technology both are work of art!
One of the coolest, most informative channels ever! I cannot tell you how much these animations impact such abstract yet crucial learnings!

Great Explanation! I love it when people like you take such complex concepts and explain them clearly in such an easy way to understand.
This technology is so advanced to me that it seems like it was made by aliens.
Now imagine the tech we'll have in the upcoming decades.
it was... it is...
If you want to see alien hieroglyphics just look at the math behind frequency modulation.
It's deceiving to learn about it like this, because you don't realise the middle steps that came before.
now look at the mri and how we use giant nitrogen cooled magnets to exploit quantum propriety of water to take microscome-like picture of inside of the body
and fmri that does the same but also use the one Fe atom of red bloodcell to estimate if it have oxygen on it and hence where the brain use the oxygene and hence witch area is active
you and i probably don't understand (and by that i mean we could not make it) most technology past 1800-1900
Absolutely brilliant analogies to explain extremely difficult concepts such as phase shifting. Awesome video as usual!
