distance: this parameter is used to set the exact distance value
between two devices (in kilometers). This parameter changes time

between two devices (in kilometers). This parameter changes time
values for some delays and time-outs of 802.11a/b/g protocol thus
making possible to work on longer distances with smooth adjustment.
There are several ways to manage this parameter:
o if you set an exact value, this value is used no matter what the
connection method is used
o If the CPE has auto value instead of a number (by default), the
CPE will configure its parameters using Base Station commands.
It is enough to set a numeric value on a Base Station (the

o when knowing exact device's geographical coordinates (e.g.
using GPS) you can specify their values in ―sys gpsxy‖
command and distance parameter set as auto on all devices
including the Base Station. In this case devices will automatically
adjust their settings selecting an optimal value for the distance
including the Base Station. In this case devices will automatically
adjust their settings selecting an optimal value for the distance
parameter. Base Station will calculate a distance to the remotest
subscriber, and subscriber will calculate a distance to the base
subscriber, and subscriber will calculate a distance to the base
station. If the CPE has a link coordinates information it will use
this information, otherwise it will use the distance parameter
this information, otherwise it will use the distance parameter
value got from the base station.
o If distance parameter is set to 0 radio module will use default
settings.
