We'll get to that real soon...but first, what is Bluetooth?
Not this grumpy blue tooth...Bluetooth is a wireless technology standard (not a piece of plastic you stick in your ear for phone calls). Of course the two are related, but the wireless connection between your phone and the earpiece is called Bluetooth… not the piece itself. As you can imagine, Bluetooth was developed as a way to exchange data over a short range (like from your pocket to your shoulder) without the need for wires. That’s why it is used for wireless headsets, hands-free calling through your car, and wireless file transfers. In engineering speak, Bluetooth operates in the 2400-2483.5 MHz range within the ISM 2.4 GHz frequency band. Data is split into packets and exchanged through one of 79 designated Bluetooth channels (each of which have 1 MHz in bandwidth).
