Set the power output of the wireless radio. You may not
require 100% output power. Setting a lower power output can
enhance security since potentially malicious/unknown users in
distant areas will not be able to access your signal.
Set the interval for keepalive messages from the AP to a
wireless client to verify if the station is still alive/active.
Beamforming is a signal processing technique used in sensor
arrays for directional signal transmission or reception.
This is achieved by combining elements in an antenna array in
such a way that signals at particular angles experience
constructive interference while others experience destructive
interference. Beamforming can be used at both the
transmitting and receiving ends in order to achieve spatial
selectivity. The improvement compared with omnidirectional
reception / transmission is known as the directivity of the
array.
