Configuring The Network Profile Parameters - Cisco 7925G Deployment Manual

Note: It is recommended not to use the 192.168.1.0 /24 network for the wireless LAN interface as that network is used by the
USB interface by default. If wanting to use the 192.168.1.0 /24 network for the wireless LAN, then either change the USB IP
address on the phone or do not charge the phone via USB.

Configuring the Network Profile Parameters

Use the following guidelines to configure network profiles.
•
The Cisco Unified Wireless IP Phone 7921G supports multiple network profiles that allow one SSID per network
profile. 0 length SSIDs are not allowed.
•
5 different 802.11 modes are available.
Auto-RSSI
802.11a
802.11b/g
Auto-a
Auto-b/g
As of the 1.3(3) release, Auto-a is the default 802.11 mode, so it will scan both 2.4 and 5 GHz channels and attempt to
on the 5 GHz band if the configured network is available.
In previous releases, the Cisco Unified Wireless IP Phone 7925G would default to Auto-RSSI mode, which would
attempt to associate to the access point with the strongest signal.
802.11a mode will only scan 5 GHz channels and 802.11b/g mode will only scan 2.4 GHz channels, where it will then
attempt to associate to an access point if the configured network is available.
For Auto-a and Auto-b/g modes, this is giving preference to one band over another. At power on, will scan all 2.4 and
5 GHz channels then attempt to associate to an access point for the configured network using the preferred band if
available. If the preferred band is not available, then the Cisco Unified Wireless Phone 7925G will try to use the less
preferred band if available. If the phone roams out of coverage of the preferred band, where the less preferred band
signal is available, then the phone will attempt to associate to that less preferred band. Once associated to the less
preferred band, there is no mechanism to check if the preferred band is available again. For the phone to roam back to
the preferred band, the less preferred band signal will have to be exhausted.
Some deployments may use one band for indoor (i.e. 5 GHz) and the other for outdoor coverage (i.e. 2.4 GHz). In this
case, set the phone to either Auto-a or Auto-b/g mode, depending on the preferred band. Then to ensure the phone is
always associated to the preferred band, will need to ensure the less preferred band signal is not available, where the
phone can then re-scan the preferred band and attempt to associate if the preferred band signal is available.
•
To extend battery life, ensure the call power save mode is configured for U-APSD/PS-POLL mode to utilize power
save mode during active calls.
Active mode "None" may need to be used instead of U-APSD/PS-POLL if the access point does not support power
save enabled clients.
