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.
The wireless phones exhibit Wi-Fi capabilities that can use 802.11a, 802.11b, 802.11g, and 802.11n Wi-Fi.
The following figure shows a typical WLAN topology that enables the wireless transmission of voice for
wireless IP telephony.

When a phone powers on, it searches for and associates with an AP if the device wireless access is set to On.
