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
distance to the remotest CPE); all other CPEs will automatically
adjust their work. While configuration showing, there might be
the current distance value after auto parameter: auto (XX)
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 parameter.
Base Station will calculate a distance to the remotest 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 value
got from the base station.
Using several checkboxes you can manage different regimes for the radio:
• wocd mode. Disables carrier sense on the radio interface when sending
data packets. May only be used on a base station working in WMA
(Wireless Marker Access) mode. Reduces the number of retransmitted
packets, thus increasing effective throughput of a multipoint radio link. "-
vocd" re-enables the standard mechanism of permanent carrier sense.
Initial setting is "-wocd" (carrier sense enabled).
• burst mode consists in grouping several short packets with the same
destination address on a radio link into larger packets, thus cardinally
decreasing the response time for applications generating streams of
short packets..
• pwrctl enables automatic management of transmitter's emitting power.
Along with radiointerface parameters, the user can view/change other interfaces
parameters::
• eth0 – Ethernet interfaces
• lo0 – Loopback interface
• null0 – auxiliary interface
The application has the following functionality to manage the interfaces:
• Add/delete/change primary and secondary (alias) IP-address on each
interface
• Change the state of the interfaces (up/down).
• Change MTU (Maximum Transfer Unit) parameter for each of the
interfaces
