How Bluetooth Works
Ғылым және технология
My wireless speakers, earphones, hands-free calling - what’s the magic behind Bluetooth tech? How does it all work?
The idea of what we call “Bluetooth” today was first introduced back in 1989. Dr. Nils Rydbeck, who was the chief technology officer at Ericsson Mobile, and inventor Dr. Johan Ullman had this revolutionary idea to develop a pair of wireless headsets. They brought Dr. Jaap Haartsen on to the project. A mere 5 years later, he’d be the engineer who made the breakthrough and came out with the first protocol.
It took a few more years to perfect the technology. But finally, in 1999, they presented their first hands-free headset to the world at the Comdex computer exposition and trade show in Las Vegas.
SUMMARY
- Three companies were working separately to create short-range radio technologies that would connect computers and different devices using short-wave frequencies. But since the invention was in its early stages, Intel, Ericsson, and Nokia decided that the best way to proceed was to create a single wireless standard.
- Bluetooth works a lot like Wi-Fi. It uses radio waves to send data between devices at short distances. Now, whereas Wi-Fi uses radio waves to transmit data between your router (where your Wi-Fi comes from) and your device, Bluetooth does it between devices.
- Bluetooth can connect to 8 devices at the same time without any interference from other wireless items like garage doors or baby monitors.
- The Bluetooth transmitters in both your computer and your devices use 79 different frequencies in that range.
- If you’re wondering what devices use Bluetooth nowadays, the answer is almost all of them. Phones, headphones, earbuds, speakers, stereos, TVs, cameras, cars, tablets, game consoles, you name it!
- When Bluetooth first came out, it was really easy for someone to access your data without your permission. But over time this technology has become more secure.
- There’s this trend called bluejacking where a person or company can send you their electronic business card or an ad as a text message using Bluetooth. Of course, when you see that, you either ignore it or panic! But this is something that mostly happens in public places where everyone is using their phones.
- The amount of non-ionizing radiation present in Bluetooth headphones is a lot less than what’s in a typical cellphone.

When I was younger, I always thought bluetooth would be the future because it looks super futuristic compared to other technology. Here we are with airpods, which is a form of bluetooth headphones, very cool
Fun fact (and a correction), I was working at IBM back in the 1990's when Bluetooth was just a pilot project and we were testing it. And the companies involved in creating the Bluetooth standard were actually Intel, Ericsson and Nokia, yes, but also IBM and Toshiba. Not a fact you would find in standard writings about it sometimes, because most mention only Ericsson, Intel and Nokia. But if you look, you will find it was 5 companies, not 3. Three companies invented the tech. but 5 of them launched it and the Bluetooth standard and the Bluetooth SIG (special interest group) in 1998 and IBM and Ericsson were the founding signatories. IBM and Ericsson also helped improve the footprint of 5G recently too.

If you guys were listening, you would have heard how Bluetooth works: Frequency hopping, protocol exchanges, address assignment, security protocols, etc. - Perhaps you zoned out when you heard all this and don't remember seeing it demonstrated or hearing it said? If so, then rewind the video to about 7m.10s mark - He explains it all and even throws in some rudimentary graphics for those with elementary attention spans!
I use BT everyday for calls and music thru headset. This is good info to know.

Hi great video. Quick question if i may. i have a Behringer xr18 digital mixer and i want to run 2 Separate mixes out for inear monitors. I am thinking of going this way with bluetooth and using pods. I know i will have to use a conversion from 1.8 to female xlr and then it will be OK. My question is -I am going to run 2 of these Airfly pros together at the same time. Will that cause cross frequency ? i need both mixers to be different. Whats your thoughts?
I use my bluetooth everyday, with wireless headphones too listen to music, but thanks for the info, now I know what it is all about. 👍

I use a Bluetooth headset which simultaneously connects two devices. I connect my Android mobile phone and my Windows laptop simultaneously. While I attend virtual meetings on my laptop, my headset alerts me and switches automatically to my mobile phone whenever a call comes (also if I make a call myself) and automatically switches back to my laptop when the call ends. Amazing technology.

Very interesting and informative. I think I've never really used the Bluetooth technology until the beginning of this month when I purchased my first TWS earbuds. Here where I live there are trams and electric buses and when I'm using my earphones nearby the electric cables, my earphones get a lot of interference and that's really frustrating. 😕

It's called latency, it'll be there in almost all wireless devices. You need to check the latency before purchase. It should be minimum. Recently snapdragon has released a new Bluetooth chip with Aptx technology which they claimed that has very less latency.

Good Video! But I got another questions: if WiFi and Bluetooth have the same frequency, what is the difference between them and why do they not interfere each other? How can e. g. my Smartphone distinguish them?
