Device Configuration and Administration
A UC520 with an integrated AP can be used in order to provide WiFi coverage if the desired service area is within the vicinity of the physical UC520 unit. This option is optimal for a small office environment that installs the UC520 as a desktop unit.
Even though the integrated access point supports voice over wireless, for optimal performance and a higher requirment for of voice over wireless LAN (VoWLAN) clients, like the Cisco 7921 IP Phones, we recommend that the customer go with the Cisco AP521G Autonomous Access Point or the Cisco Mobility Express solution with the LWAPP based AP521 and WLAN Controller 526.
Configuration Example for UC520 Integrated AP
The UC520 router ships with a factory default configuration and has two pre-configured SSIDs: uc520-voice for VoWLAN clients attached to VLAN 100 and uc520-data for WLAN data clients, attached to VLAN 1. The default SSID configurations have open authentication and no encryption as shown below:

Client Configuration
WLAN data connectivity:
If the customer wishes to retain the default configurations, he should create a "profile" and add "uc520-data" as the SSID. Authentication should be open and no encryption is required.
WLAN voice connectivity:
On the Cisco 7921 phone, navigate to these menus and configure as recommended:
Settings > Network profiles > profile1 > network configuration > DHCP enabled: Yes
Settings > Network profiles > profile1 > WLAN configuration > SSID: uc520-voice
- If the 7921 displays a LOCK symbol when trying to make changes, pressing **# will UNLOCK these menus.
