Transmitter Power Select the transmitter power.
Setting a higher transmitter power increases the access point's range. A
lower power reduces interference with other access points in the vicinity.
The default value is Full. It is not necessary to change this value, unless
there are other access points in the vicinity.

Antenna Selection Multipath distortion is caused by the reflection of Radio Frequency (RF)
signals traveling from the transmitter to the receiver along more than one
path. Signals that were reflected by some surface reach the receiver after
non-reflected signals and distort them.
UTM-1 appliances avoid the problems of multipath distortion by using an
antenna diversity system. To provide antenna diversity, each wireless
security appliance has two antennas.
Specify which antenna to use for communicating with wireless stations:
• Automatic. The UTM-1 appliance receives signals through both
antennas and automatically selects the antenna with the lowest
distortion signal to use for communicating. The selection is
made on a per-station basis. This is the default.
• ANT 1. The ANT 1antenna is always used for communicating.
• ANT 2. The ANT 2 antenna is always used for communicating.
Use manual diversity control (ANT 1 or ANT 2), if there is only one antenna
connected to the appliance.
