Video explaining how Bluetooth actually works is leaving people in awe of how advanced it is

We often take Bluetooth for granted, thinking it's just a simple wireless connection.

But this YouTube video is blowing people's minds, revealing how advanced it really is.

So how does Bluetooth work exactly?

The video starts off by saying that 'Bluetooth is literally indistinguishable from magic.'

Then, it goes on to explain that your tech devices connect through light, though not one that we can see.

Without getting too science-y, visible light to humans only covers a very small percentage of the electromagnetic spectrum.

Unlike visible light, Bluetooth light operates at a wavelength of 121-124 nanometres.

Not only can we not see it, it can travel through walls due to the wavelengths being extremely long, similar to how 'visible light passes through glass.'

The two connected devices communicate through '1s and 0s' - where the video says to imagine the wavelengths as different colour which correlate with the numbers.

'If your phone wants to send a 1 to your earbuds, your antenna turns purple. The antenna on the earbuds sees this and tells the microchip that it's a 1. Then the microchip writes down a 1,' the video described.

The same thing happens for sending a 0.

It's a process of your smartphone's antenna sending information to your airbuds and it happens about a million times a second.

The YouTube video then goes on to answer the question of how two sets of airbuds in the same room know not to cross-connect with either phone.

This gets a bit more technical, but you have to imagine that instead of a few wavelengths of different colours, there's 79 sections altogether.

'Each channel has its own specific wavelength for 1 and 0,' the video explained.

You could be on one channel whilst the other person in the room is on an entirely different channel, therefore you wouldn't be able to listen in on your friend's iPhone with your airbuds.

Additionally, when your smartphone and airbuds are paired, they do something called 'frequency hopping' which basically means they hop around the channel frequency about 1600 times a second.

Another thing to note is that if you imagine earbuds to be a lock. By clicking the pair button on the Apple Airpods case, it sends out a key through its antenna.

These keys can then be seen on your iPhone of all the Bluetooth devices that are trying to pair.

In response to the simplified yet educational video, one YouTube comment read: '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.'

Another simply said: 'Technology these days'.
