Antenna Gain Set the antenna gain used with the selected antenna type
between 0.00–15.00 dBm. The Access Point’s Power
Management Antenna Configuration File (PMACF)
automatically configures the Access Point’s radio transmit
power based on the antenna type (provided in the CLI), its
antenna gain (provided here) and the deployed country’s
regulatory domain restrictions. Once the antenna type and
gain are provided, the Access Point calculates the power
range.
Antenna gain relates the intensity of an antenna in a given
direction to the intensity that would be produced ideally by
an antenna that radiates equally in all directions
(isotropically), and has no losses. Although the gain of an
antenna is directly related to its directivity, its gain is a
measure that takes into account the efficiency of the
antenna as well as its directional capabilities. Extreme
Networks recommends that only a professional installer set
the antenna gain and the antenna type.
