Bluetooth function introduc: Bluetooth technology, a short distance

wireless communication technology, can simplify the communication

between palmtop computers, notebook computers and mobile phones, can

also simplify the communication between these equipments and the internet,

so the data transfer between modern communication equipments and the

internet can be swifter and more efficient and the application of the wireless

communication has been accelerated. The Bluetooth technology realize the

wireless data and sound transfer from one point to several points, the transfer

bound is a 10 meters radius sphere to the one point, the transfer bandwidth is

1Mbps, and the communication medium is electromagnetic waves from

2.402GHz to 2.480GHz.
