channels available and not as many interferers as the 2.4 GHz band has.

type when the Cisco Unified Wireless IP Phone 7925G Series is running firmware version 1.3(4) or later in order to enable fast
secure roaming.
If the Cisco Unified Wireless IP Phone 7925G Series is running firmware version 1.3(3) or earlier, then enable WPA policy
