TX Power Control
Transmit Power Control uses standard 802.11d frames to control transmit power within an infrastructure BSS. This method of power control is
considered to be an interim way of controlling the transmit power of 802.11d enabled clients in lieu of implementation of 802.11h.
The Transmit Power Control feature lets the user configure the transmit power level of the wireless interface at one of four levels:
•
100% of the maximum transmit power level defined by the regulatory domain
• 50%
• 25%
• 12.5%
When Transmit Power Control is enabled, the transmit power level of the card in the AP is set to the configured transmit power level. The
power level is advertised in Beacon and Probe Response frames as the 802.11d maximum transmit power level.
When an 802.11d-enabled client learns the regulatory domain related information from Beacon and Probe Response frames, it learns the
power level advertised in Beacon and Probe response frames as the maximum transmit power of the regulatory domain and configures itself
to operate with that power level.
As a result, the transmit power level of the BSS is configured to the power level set in the AP (assuming that the BSS has only 802.11d
enabled clients and an 802.11d enabled AP).
