How does Bluetooth Even Exist??? 

Instructions unclear, created wifi with sticks, rocks and water instead

Technology is literally indistinguishable from magic sometimes.

That is what we call :- Fun,education, information

DUDE THAT'S WHAT I'M SAYING! The age of wifi (or anything wireless for that matter) is the largest leap mankind has done in ever. Literally. And to have been alive in that timeframe is absurdly overwhelming. Like when I was a kid, I grew up with dial up, which even as a kid makes sense. And now even as an adult, Wifi still sounds like Sorcery.

I guess the algorithm works if you make such high quality content.

Congratulations man. You just casually taught over a million people how Bluetooth works in just 4 minutes. You deserve your success, keep up the good work. God bless you.

This explains why, nobody ever had cellphone reception when you go to concerts, or other events with a large number of people

maybe the best educational video i've EVER watched. straight to the point, unforcingly funny, high quality and all that while being the shortest and the most comprehensive explonation i've seen on this topic. this video itself is proof that there's no need to do a 5minute introduction to a topic. most channels would spend 5 or more minutes talking about the inventor of bluetooth, literally...

I HAVE LITERALLY THOUGHT ABOUT EXACTLY THIS. Like I was thinking about how if I was teleported 10000 years back and told to spend my whole life trying to recreate Bluetooth I would be miserably lost

I went into this video thinking I would 100% still not know what bluetooth was afterwards. I'm genuinely shocked at how well explained this was. Entire production: absolutely phenomenal!

yea i still don't get it.

I genuinely love how this guy can make learning fun and informative at the same time unlike school

very refreshing to see quality content that isnt extened for 10 mins with filler or compressed to be a yt short.

insane production quality for your channel size. please keep making videos!!

Instantly subbed. No long talking. Straight to the point. Thanks!

My g Hedy Lamarr comin' in clutch with that frequency hopping

It's impressive that Bluetooth was already present on old keypad phones and just became even bigger to the point of becoming an industry standard today

This was definitely worth watching at 2 am, now I can annoy my friends with this new information, thnx

I've wondered about this for so many years, strange I didn't find a video sooner but I'm scared to watch it honestly. If I understand it, it won't be magic anymore.

3:10 this is the stage where hackers would try to eavesdrop, before that phone is connected. Pro tip: if you’re not using Bluetooth just turn it off

I feel like this explains the simple part and not the actual magic: how are we able to create these beams of light that we can’t even see out of thin air?

Fun fact: the military also uses frequency hopping for radio communications, although they do it at a much higher change rate and over a much larger span of frequencies. They also change the key for that specific set of "hops" daily, making it almost impossible to listen to the military if they dont want to be listened to

thank you for answering and simplifying the questions i never dare to ask or lookup. Got yourself a new sub!

I love that you answer any question someone could ask, I actually feel like I learnt something new now

The quality of this channel is unreal. It’s both entertaining and educational. Great stuff man!

10/10 explanation. I loved how simple it is that even a kid with no previous knowledge could watch this video and, in less than 4 minutes, understand the basics of ultrasonic waves, encryption keys, etc. in a very engaging way. Also, apart from kids, people with previous knowledge can have a good time with this video because of how fun you make it. Apart from all this, people who didn't know any of this can get interested and use this information for further research. I genuinely have never seen a channel like this one that makes any subject or piece of information fun to learn for literally everyone. Wish you the best, you've earned yourself a new Sub, and I hope many others.

The pokemon analogy..this might be one of my favorite videos ever.

You have a really neat way of explaining things. I like it! Subscribed!

As someone with an interest in telecommunications, I'm glad other people are asking these questions, because telecommunications are WAY more complex than people think, and folks really just take it for granted. Slight correction, at 0:55 you're describing frequency-shift keying or FSK (changing between 2 frequencies to send a 1 or 0) where most modern wireless modes use phase-shift keying or PSK. The difference is that in phase-shift keying, the device isn't modulating (changing) the frequency, and is instead modulating the phase of the radio wave. The change in phase is what communicates a 1 or 0. In fact PSK is more efficient because it's usually groups of bits and actually communicates a 00, 11, 01, or 10 based on what phase the wave is. PSK is also more robust which is why it's used in modern solutions. Digging into the Bluetooth specification, it seems to use a combo of FSK and PSK, but for fast data rates like audio I suspect it's mainly PSK, Bluetooth-LE seems to be where FSK is used most.

Technology these days

Found your channel today, I absolutely love it, keep the good work going!

this is the greatest channel ever please keep it up i love knowing how things work!!!

I can't even describe how often I've listened to music with my AirPods asking myself how tf bluetooth works. But I also never looked it up. Now this random video was recommended to me on my starting page and I clicked it. Thank god that I did. I watched all your videos back to back now. This. may be my new fav YT channel

we makin it out the algorithm with this one

I just stumbled upon this video at random, and after quickly binging every video you’ve uploaded at this point, I can say you are easily one of the most entertaining science channels I’ve seen in a long time. Keep up the good work ❤

Thats such a nice way to explain how something works in very easy way! Keep up! You got my sub

As an electrical engineer this is a good way to simply teach the principles of Bluetooth without being too confusing, good job teaching people man, keep it coming!

1:45 that would explain why at school my AirPods would struggle to connect. With the 1000 other students present and then when they were connected sometimes they would struggle to play.

Great video. Possibly the first time I've subscribed to a channel without going to their page first. You earned that one.

Great job. Very well explained. I’m extremely excited to see your future videos

I'm shocked about your effectiveness in explaining such a complicate topic in such a simple way for everyone to understand, at least at a basic level. And for packing it up in such a fun way is top notch (I loved the genius in the background music, especially when it was just a little soft to create the atmosphere but not too much to not interfere with your explanations). You deserved this follow.

this is the only video i couldn't help but liking and subscribing after he asked I've never seen anyone ask so creatively

Oh my god, this channel is amazing. so far I have watched two videos and both are high quality stuff.

Love how unserious but yet educational this is, well balanced

i legit thought bluetooth was made out of human tooth and blue paint. i was wrong

Welp new favorite channel to watch good work man

Absolutely incredible video! Leaving a comment to help support the channel lol. Keep up the great work!

bro ur way of explaining is so fun and pretty much able to oversimplify the whole thing but at the same time not misleading the information

Can’t belive this video has only 248 views, it deserves at least a million views

Thank you for explaining this in 3 minutes instead of 30. Absolutely subscribing to you

Thanks a lot mate, I really appreciate your hard work, I enjoyed the video and I didn't think it will be funny as that 😂❤️❤️❤️❤️❤️

Your content is seriously refreshing. Please never stray from this format. No bullshit and straight to the point, yet entertaining. Subscribed. I wish you great success!

This is such a complicated concept so eloquently and simply explained. Really good video

This explanation was incredibly easy to understand. I am impressed. Good job!

I love these kind of videos where you actually learn something without it being boring, keep it up!

This is one of the best educational videos I’ve ever seen. All the information stuck easily, amazing work man

Wow. Thanks. This was so detailed while being very short!! And i understood everything

The first two lines are so amusing they literally made my day Thank you so much!!

This is actually very interesting. I actually had an issue pairing my buds, and I ended up being able to listen to my music while also having my mom's notifications and typing. It was able to connect to two devices at once. And then it disconnected itself, and I've never been able to replicate.

The fact that this is the simplest concept you've explained is amazing. Super happy to have found your channel!

As a tech guy who already knew all of this, this is quite literally the best way to explain this... I literally don't understand how he managed to explain it with such ease, in a way every one would understand on the first try

Nice way of providing educational information Bro! I like your style. 👍👍👍

I was literally just thinking about this whole 'how does Bluetooth & privacy etc work' whilst nodding off to sleep last night. I didn't discuss it with anyone, it was literally just a thought in my head...and now the algorithm gods have answered that thought. This is creepier than the idea that my phone is listening to my conversations; this is mind reading. I hate it, I love it.

I remember watching a 15 minute video on Bluetooth and still walking away confused. Somehow your much shorter video was both more entertaining and informative, well done!

Very very veryyyyyy well put and said. Thank you for sharing valuable info in an interesting way

This is my first time commenting EVER in a youtube video, And I am glad I came across this channel, because I always have these kinds of thoughts every now and then, and I am glad someone actually created a channel to answer all of the questions. Keep up the work Just subscribed.

Didn't even mention one of the craziest things about bluetooth: each phase of the wave can encode a different bit, meaning the top and bottom of the waveform aren't symmetrical but independent of eachother. This doubles the bitrate of the signal and manages not to skyrocket the fault rate enormously, which is truly some Nordic magic.

This video was simple and informative. Very well put together. Thank you for your efforts, you have earned a subscriber.

I just love your video's man, very inspiring

Only true men listen to Shakira

High quality video from a channel only a month old with a tenth of the subscribers I would expect? Excited to see how this pans out. Keep up the great work!

yo i aint joking this might be the most funny yet interesting video I watched on youtube... Hats off mate

That was awesome dude! Always woundered about that 🔥

how dare this channel only have 2k subscribers and not 5 million as i thought? this video kept me entertained a way a bigger youtuber could never do 🤩

idk why I didn't find this channel earlier, absolutely killer content, funny AND informative. Keep the good work up my friend

This the most funny science lesson I've been to in years😂 lol keep up the content ma dude

Awesome vid man! Keep it up!!

There is also a low bandwidth mode with like 21 different modes, I had to make a paper on Bluetooth and other stuff a while back. This is pretty well explained, interference is not really mentioned apart from "the 158 bluetooth devices in one room" analogy. Since the Wi-Fi signals also interfere with the Bluetooth signal/microwaves (a literal physical one), etc.

Absolutely great, short format with clear and funny explanations! +1

I like this channel. Very interesting, entertaining and educational. Subbed

Wow. That’s an instant subscribe, great video dude.

Very well-explained and entertaining as well! Also, this has to be one of the fastest-growing channels I've ever seen. Keep doing what you're doing!

I fully expected to be confused when the video was over, but this was surprisingly easy to understand. Well done!

Bro, you've earned my sub simply from the alignment of the subscribe button lighting up when the tip screen flips 😂

Lord, this is the best video I've seen in years, thank you man

As someone who has always been curious about this shit but never researched i aplaud you for giving me this much condensed information in such a short timespan. Thank you for big brain

Amazing. Over 4400 people subscribed because of 6 vids I mean your channel is amazing,a way to explain things which is not only fun,but also attaches info to mind like super glue or something, absolutely like it!

And to think about a month ago you were at 1,000 subscribers. You just earned yourself another one!

This was a very good video. I am an electrical engineer specifically working in signal processing and communication waveforms. Sometimes my job has me solve insane problems. Bluetooth is just the start. However it gets more complicated when you are talking to one moving object or two moving objects at insane speeds with high noise. Cell phone towers also can be very interesting but what is probably the most interesting is communication with space systems. Again you did a great job of explaining very simple concepts of digital communications.

Great channel, didnt belive my eyes when I saw you only have 9.9k subs, will defiantly make it big on youtube if you continue this high level of production

Bruh I’m a very stupid man when it comes to technology so I really appreciate tech savvy people like yourself and I appreciate all the knowledge you got. Thanks for sharing this content with us. I hope your channel is able to grow more❤️🙌🏻

I almost never like or comment, I really understand how bluetooth wifi etc works. The way you explain things with such an ease, full of comedy a very friendly voice, good selection in infographic and animation, let me tell you, you have an absolutely amazing mind. I wish you all the best for you and your channel!

I love this channel hittin a few milli fa sho. Glad I'm here now though. Cheers m8

Hey, thanks! Really useful, and clearly. I’d like to write long comment. So, I hope, that on this way, more people will see this interesting Chanel, wish u succes👍

crazy well made video, deserve a lot more attention!

Nice analogies. I’m an EE and was involved in developing a BT radio during its infancy in 1999. There is a LOT of science behind the technology (or any wireless technology) that just can’t be covered in a brief video.

Thank you for making this video pal. I learned something new today.

Ok so this is actually like an incredible video and i love you

Incredible video! Straight to the point and easy to understand. 👏
