Bluetooth
Bluetooth-equipped devices can communicate without wires, using frequency-hopping spread spectrum
(FHSS) radio frequency (RF) to transmit and receive data in the 2.4 GHz Industry Scientific and Medical
(ISM) band (802.15.1). Bluetooth wireless technology is specifically designed for short-range (100 meters
(328 feet)) communication and low power consumption.
Devices with Bluetooth capabilities can exchange information (such as files, appointments, and tasks) with
other Bluetooth enabled devices such as printers, access points, and other mobile devices.
Adaptive Frequency Hopping
Adaptive Frequency Hopping (AFH) is a method of avoiding fixed frequency interferers, and can be used
with Bluetooth voice. All devices in the Bluetooth network (piconet) must be AFH-capable in order for AFH
to work. There is no AFH when connecting and discovering devices. Avoid making Bluetooth connections
and discoveries during critical 802.11b and other 2.4G WLAN communications.
