Bluetooth Technology
The Cisco Wireless IP Phone 882x Series are full-feature telephones and provide voice communication over
the same wireless LAN that your computer uses. In addition to basic call-handling features, your phone
operates with Bluetooth wireless headsets, including certain hands-free call features.
Bluetooth devices operate in the unlicensed Industrial Scientific Medicine (ISM) band of 2.4 GHz, which is
the same as the 802.11b/g band. This unlicensed band in most countries includes the frequency range from
2400 to 2483.5 MHz. Bluetooth enables low bandwidth wireless connections within a range of 10 meters.
The best performance is in the 1 to 2 meter range. Synchronous voice channels are provided by using circuit
switching and asynchronous data channels are provided by using packet switching.
