Huawei EchoLife HG520 User Manual page 77

Select 54g LRS if you are not familiar with 802.11b
equipment.
54g protection: In Auto mode, HG520 can improve
802.11g performance in 802.11g/802.11b mixed network
through RTS/CTS.
The off protection mode can maximize 802.11g throughput
in most cases.
Regulatory Mode: Include 802.11d and 802.11h. 802.11d
is a roaming standard that decide what frequency should be
used for data transmission in different countries to ensure
the correct transmission. 802.11h is the evolution of 802.11a
with the new ability of Transmit Power Management
extensions and wireless channel selection so as to comply
with European standards.

TPC Mitigation: Transmit power control is a method of
lowering the transmit power used by a WLAN and it reduces
WLAN interference with satellite services in the 5GHz band.
With the 802.11h amendment to the 802.11a PHY and MAC
layer, TPC mitigation becomes a reality in the 5-GHz band.
Manufacturers are now poised to implement one
standards-based solution to address interference concerns
around the world.
Transmit Power: The amount of power used by a radio
transceiver to send the signal out. Transmit power is
generally measured in milliwatts, which you can convert to
dBm. The larger the percentage of transmit power, the
clearer the signal sent.
