How does Bluetooth Even Exist???

Today i answer the biggest question we all never really thought about, How does Bluetooth even exist?

here is some credit for music in the video:

sorry i butchered it with an airpod

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

[Bluelazerz]

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

[subhamsethi]

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

[wilhelm]

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.

[FolkoMagipaw]

Technology is literally indistinguishable from magic sometimes.

[CBob.]

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!

[_Ank_]

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

[KiraAsakura]

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.

[emmaline.]

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

[TheTriangle]

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

[thatguy]

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...

[suri_atty]

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

[lucho.g.]

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.

[CJDavis-jsmr]

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

[ratiod]

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

[sohamvij]

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

[tristanb.]

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

[UnclePhil]

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

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.

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