Transmit Power
The
Transmit Power
drop-down list contains different options for Ad-Hoc and Infrastructure mode. Automatic
(i.e., use the current AP settings) and Power Plus (use higher than the current AP settings) are available for
Infrastructure
mode.
Adjusting the radio transmission power level enables the user to expand or confine the transmission area with
respect to other wireless devices that could be operating nearby. Reducing coverage in high traffic areas
improves transmission quality by reducing the amount of interference in that coverage area.
