Chapter 6 Understanding the VoIP Wireless Network
Configuring Wireless LAN
Note Voice over the Wireless LAN (VoWLAN) via Outdoor MESH technology (Cisco 1500 series) is not
supported in the Cisco Unified IP Phone 9971.
Third-party access points are not supported since there is no interoperability testing with these access
points. However, if the access point supports the key features and follows the standards, the Cisco
Unified Wireless IP Phone will be compliant.
Wi-Fi compliant APs that are manufactured by third-party vendors will support the Cisco Unified
Wireless IP Phone 9971, but might not support key features such as Wi-Fi MultiMedia (WMM),
Unscheduled Auto Power Save Delivery (U-APSD), Traffic Specification (TSPEC), QoS Basic Service
Set (QBSS), Dynamic Transmit Power Control (DTPC), or proxy ARP.
Supported Antennas
Some Cisco Access Points require or allow external antennas. Refer to the following URL for the list of
supported antennas and how these external antennas should be mounted.

Note The Cisco Aironet Series 1130 and 1140 access points must be mounted on the ceiling because they have
omni-directional antennas.
Configuring Wireless LAN
Ensure that the Wi-Fi coverage in the location where the wireless is deployed, is suitable for transmitting
video and voice packets.
If the Wi-Fi connectivity for voice and video has been enabled for the Cisco Unified IP Phone 9971, you
have to authenticate the Wi-Fi network using the WLAN Sign in application within your applications
menu.
To enable, to go to Applications > Administrator Settings > Network Setup > WLAN Setup >
WLAN Sign in Access and enable WLAN network.
To change the username/password must go to Applications > Administrator Settings.
For complete configuration information, see the Cisco Unified IP Phone 9971 Wireless LAN Deployment
Guide.
