 802.11h: The standard solves interference problems with e.g. satellites and radar using the
same 5 GHz band as 802.11a or 802.11n dual-band access points.
802.11d: This standard automatically adjusts its allowed frequencies, power levels and

bandwidth accordingly to the country it's located in.
Pre-Network Radar Check (Used for 802.11h only): Specifies a period of time in seconds [0-99] to
check for radar on a channel before the Access Point establishes a wireless network with the channel.
In-Network Radar Check (Used for 802.11h only): After the wireless network got established,
specifies a period of time in seconds [10-99] to check for radar when switching to another non-radar
channel.
TPC Mitigation (db): Known as Transmitter Power Control mitigation to reduce unnecessary
transmitting power radio and possible radio interference to other users.
Transmit Power: select the transmitting power of your wireless signal.
WMM (Wi-Fi Multimedia): you can choose to enable or disable this function which allows for priority
of certain data over wireless network.
WMM No Acknowledgement: Refers to the acknowledge policy at the MAC level. Enabling WMM No
Acknowledgement can result in more efficient throughput but higher error rates in noisy Radio
Frequency (RF) environment.
WMM APSD: Automatic Power Save Delivery. Enable this to save power.
Beamforming Transmission (BFR) / Beamforming Reception (BFE): Enable to increase wireless
speed by focusing and concentrating transmitted (send) and/or receive signals with a wireless client
instead of broadcast signals in all directions.
