Selecting the Transmit Power
Cisco Wireless IP Phone 7920 with firmware Release 1.08 and later can use
dynamic transmit power control (DTPC) allowing the Cisco Wireless IP Phone to
dynamically adjust its local power to the setting that the access point (running
Cisco IOS only) advertises. If this is the case, you do not need to change the
transmit power setting.
Note
If Client Transmit Power is set in the access point, the phone
automatically uses the same client power setting. If the access point is set
for the maximum setting (Max), the access point uses the Transmit Power
setting on the phone.
You might need to change the transmit power to offset the use of a higher gain
antenna on the access point.
To change the transmit power of the phone, follow these steps:
Procedure
Step 1
Choose Menu > Profiles and select the active profile.
Step 2
Scroll to and select 802.11b Configuration > Transmit Power .
Step 3
Scroll to the desired transmit power option: 1 milliwatt (mW), 5 mW, 20 mW,
50 mW, or 100 mW. The default setting is 20 mW.
