Interfaces
Among all interfaces parameters that can be adjusted in this tabsheet, the most
important are radiointerface parameters:
• Working frequency. Usually this parameter is relevant only for BS. For
the CPE the frequency (or a list of frequencies) is set in RMA protocol
configuration and determines the list of frequencies where the BS should
be searched.
• The bit transfer rate (in Kbit/s) of the radio link.
• Power of a transmitter (in milliwatts). The values of acceptable trasmit
power levels can vary depending on the type of radio module installed.
The full list of acceptable trasmit power levels is available by using "rf if-
name capabilitites" command. If the value entered is invalid the system
will automatically set a minimal adjacent value.
• System identifier of the router, a hexadecimal number in the range of 1H
to FFFFFFH. All routers that are supposed to see each other on the same
radio link must have the same identifier. To be compatible with ARLAN
655 network adapters, the identifier must be an even number. For 11
Mbit/s radio modules (PC4800, Lucent ORINOCO etc) the identifier must
be entered as a string of 6 hexadecimal digits (using digits 0 to 9 and
CAPITAL letters A to F), with leading zero's when necessary, e.g.
00A2CD.
• Distance. this parameter is used as an alternative method of link range
configuring in order to set the exact distance value 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
