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.
Safe@Office 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 Safe@Office 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.
Fragmentation
Threshold
Type the smallest IP packet size (in bytes) that requires that the IP packet
be split into smaller fragments.
If you are experiencing significant radio interference, set the threshold to a
low value (around 1000), to reduce error penalty and increase overall
throughput.
Otherwise, set the threshold to a high value (around 2000), to reduce
overhead.
The default value is 2346.
