Understanding the Phone Startup Process
When connecting to the wireless VoIP network, the Cisco Wireless IP Phone 7920
goes through a standard startup process, as described in
Table 2-5 . Depending on
your specific network configuration, not all of these steps may occur on your
Cisco Wireless IP Phone.
Configure radio
(802.11b) settings Data Rate—Allow only 11 Mbps unless
you have special device requirements.
Client Transmit Power—After a site
survey, determine the appropriate
power requirements and set a specific
Client Transmit Power setting. The
Cisco Wireless IP Phone 7920 uses the
same setting as the access point.

does not advertise Client
Transmit Power setting.
