Bluetooth adapter
Introduction :
Bluetooth (Bluetooth) is a wireless network transmission technology originally used to replace the infrared . Compared with the infrared technology, Bluetooth can transmit data without alignment of the transmission distance of less than 10 meters ( infrared transmission distance of a few meters or less ) . And with the help of the signal amplifier , the communication distance and even up to about 100 meters . Bluetooth technology is very suitable for low-power digital devices to share data with each other , such as mobile phones , PDAs , etc. . Moreover, the sound can be transferred between Bluetooth devices , such as Bluetooth headsets . Bluetooth specification widely applied mature version 2.0 , bandwidth is about 3Mbps very suitable for transfer small files (10MB or less pictures, ring tones , e-books , documents , etc. ) to facilitate and speed have both.
