Bluetooth

Bluetooth is used a lot in everyday technology; it is often used in printers and laptops and is almost certain to be in the latest mobile phones. The thing about Bluetooth is that it allows the user to communicate through devices without wires. Mobiles use a lot of Bluetooth for things like sending pictures and audio to one another and also to use a wireless head set, both of these examples need two things to communicate and are able to do it wirelessly due to Bluetooth. The one down point about Bluetooth is that it is only able to work across small distances, meaning you most of the time need to be in the same room as the other device. Bluetooth was thought about by many companies but in the end only one was able to make it first, that company was Ericsson Mobile Communication who were able to discover it in 1994 and name it Bluetooth. Although Bluetooth is very popular today there are still a lot of people that worry about the radiation that it produces as they are the same as a microwaves.
