Bluetooth Modules

A look inside the electronics of four Bluetooth-ready applications using die products

BluetoothT is the codename for a technology specification for low-cost, short-range (up to 10 meters) radio links between a broad spectrum of electronic products. Radios that comply with the Bluetooth wireless specification operate in the unlicensed, 2.4 GHz radio spectrum which ensures communication compatibility of products worldwide. Bluetooth radios use a spread spectrum, frequency hopping, full-duplex signal at up to 1600 hops/sec. The signal hops among 79 frequencies at 1 MHz intervals to give a high degree of interference immunity. Supposedly, up to seven simultaneous connections can established and maintained.

Market analysts predict sales of Bluetooth products will exceed a billion units annually starting 2006.
