Bluetooth Wireless Technology
Bluetooth enables low-bandwidth wireless connections within a range of 30 feet (10 meters). The best
performance is in the 3- to 6-foot (1- to 2-meter) range. Bluetooth wireless technology operates in the 2.4 GHz
band, which is the same as the 802.11b/g band. Because of potential interference issues, we recommend that
you:
• Use 802.11a, which operates in the 5 GHz band
• Reduce the proximity to other 802.11b/g devices, Bluetooth devices, microwave ovens, and large metal

VoIP Wireless Network Components

The wireless IP phone must interact with several network components in the WLAN to successfully place
and receive calls.

Using CDP, a device advertises its
existence to other devices and receives
information about other devices in the
network.

Usage notes
Cisco Unified Wireless IP Phones use CDP
to communicate information such as auxiliary
VLAN ID, per-port power management
details, and QoS configuration information
with the Cisco Catalyst switch.
