Understanding the Operation and Test of a Bluetooth Enhanced Data Rate Radio

摘要

Bluetooth~® wireless technology is a short-range communication system intended to provide connectivity of voice and data between information appliances. Bluetooth enables point-to-point and point-to-multipoint networking without the need for a formal wireless infrastructure. Two or more devices sharing the same wireless channel form an ad-hoc network or piconet. With one device acting as a master, up to seven other devices or slaves can be actively operating in the piconet. As Bluetooth wireless technology found its way into a variety of consumer products, applications requiring higher data rates have emerged such as streaming CD-quality audio, digital image transfer and printing. In addition, consumer demand for short-range wireless connectivity is moving beyond running a single application into a desire to run multiple applications simultaneously within the same piconet.
