7190_en_02
802.11h defines an extension of the IEEE 802.11 WLAN standard, in order to enable
approved communication on the 5 GHz band in Europe. The standard includes two
components: DFS (Dynamic Frequency Selection) and TPC (Transmission Power Control).
DFS is already configured on the default WLAN page.

TPC
The aim of Transmission Power Control (TPC) is to reduce the transmission power of a
device as far as possible. TPC is always active and cannot be disabled if a 5 GHz channel
is used. In the 2.4 GHz band, TPC is not active by default, but can be activated.
Select TPC profile
Standard: Optimizes the transmission power for a data rate of 48 Mbps.
Max. Power: Optimizes the transmission power for a data rate of 54 Mbps.
Min. Power: Optimizes the transmission power for a data rate of 11/12 Mbps.
Select TPC refresh rate
Clients that move quickly should use a high refresh rate, otherwise the connection may be
interrupted. The low rate can be used for static connections.
