What is Dynamic Transmit Power Control (DTPC) and how does it work?
A. DTPC is a new beacon and probe information element that allows the access point to broadcast its transmit power. Clients can use this information to automatically configure themselves to that power while associated with that access point. In this manner, both devices transmit at the same level. The Cisco Wireless IP Phone 7920 automatically adjusts its transmit power to the same level as the access point to which it is associated. Refer to Transmit Power Control Algorithm for more information.
