Best Practices for Battery Power Conservation The Cisco Wireless IP Phone 8821 and 8821-EX has a 2060-mAh smart battery. The battery capacity is reduced to 80% after 500 full charging cycles (charging from empty to full). The battery life also depends on the phone state and AP scanning configuration.
Page 19: Cisco Wireless Ip Phone 8821 And 8821-Ex Administration Guide For Cisco Unified Communications Manager
Access Point Configuration • For optimal idle battery life, we recommend that you use an access point that supports the Cisco Compatible Extensions (CCX) Proxy ARP feature. CCX Proxy ARP allows the phone to remain in suspend mode longer instead of waking up at each DTIM period. This reduces power consumption.
Page 20: New And Changed Information
Frequent wakeups can reduce the idle battery life by as much as 50%. • We recommend that you use an access point that supports the Cisco Compatible Extensions (CCX) Dynamic Transmit Power Control (DTPC) feature. When DTPC is enabled, the access point advertises its transmit power to all clients.
Page 21: Device Packs
Phone Configuration Files Configuration files for a phone are stored on the TFTP server and define parameters for connecting to Cisco Unified Communications Manager. In general, any time you make a change in Cisco Unified Communications Manager that requires the phone to be reset, a change is automatically made to the phone configuration file.

Devices with wireless capability can provide voice communication within the corporate WLAN. The device depends on and interacts with wireless access points (AP) and key Cisco IP Telephony components, including Cisco Unified Communications Manager Administration, to provide wireless voice communication.
Page 30: Wi-Fi Network Components
APs are critical components in a WLAN because they provide the wireless links or hot spots to the network. In some WLANs, each AP has a wired connection to an Ethernet switch, such as a Cisco Catalyst 3750, that is configured on a LAN. The switch provides access to gateways and the call control server to support wireless IP telephony.
Page 31: Access Point Association
Cisco recommends implementation of Cisco Centralized Key Management (CCKM) to enable fast roaming. For more information about Voice QoS in a wireless network, see the Cisco Wireless IP Phone 8821 Series Deployment Guide.
Page 32 AP is at full capacity. Frames to or from a client that has not been "authorized" through the CAC can be dropped, leading to call control system deregistration.
