"Designing the Wireless LAN for
Bluetooth
The Cisco Unified Wireless IP Phone 7925G Series supports Bluetooth Class 2 technology allowing for wireless headset
communications.
Bluetooth enables low bandwidth wireless connections within a range of 30 feet, however it is recommended to keep the
Bluetooth device within 10 feet of the phone.
Up to five headsets can be connected, but only the last one connected is used as the default.
The Bluetooth device does not need to be within direct line-of-sight of the phone, but barriers, such as walls, doors, etc. can
potentially impact the quality.
Bluetooth utilizes the 2.4 GHz frequency just like 802.11b/g and many other devices (i.e. microwave ovens, cordless phones,
etc.), so the Bluetooth quality can potentially be interfered with due to using this unlicensed frequency.
Bluetooth Profiles
The Cisco Unified Wireless IP Phone 7925G Series supports both the Bluetooth Headset and Handsfree Profiles.
With a Bluetooth Headset Profile capable headset, the following call functions can be performed.
