How does bluetooth actually work?
In: 77
Well that’s a really broad question and I would first ask a question in response: what exactly do you mean by Bluetooth actually working?
A very broad explanation would simply be that it is like a fancy personal radio. It works off the same technology as the radio waves that you pick up in your car. The same radio waves that engineers started messing with over a hundred years ago, just now we can make them really specific and not interfere with all the other waves around.
So in essence, rather than a big radio tower blasting waves for any random person with a radio to hear, Bluetooth is just a mini tower/transmitter so you can do whatever you specifically want with that wave. This could be connecting your own music, using that signal to control something, whatever.
