3. The link can be claimed to be working when the following requirements are
met:
• Good signal levels. For low bitrates (<=18 Mbps) signal levels of 10-
12 dB and higher are appropriate. For higher bitrates (24 and 36
Mbps) signal levels of higher than 18-20 dB should be achieved. For
QAM64 bitrates (48 and 54 Mbps) signal levels of 30 dB and higher
should be achieved for a reliable link
• Low or zero repeats and errors. Please use “muf stat” command to
see statistics on errors. “muf stat clear” command clears the
statistics.

• Link stability. Please check system log (“sys log show”) if remote
sides of the link are permanently connected
Keep in mind that the antenna alignment should be performed slowly and
with pauses.
Also, important to remember that “mint monitor” command is a passive
command and does not generate any traffic. Thus, it is recommended to
put some load on the link while using “mint monitor”
4. Interference can be a possible reason for the link quality degradation
(number of repeats increases, lower signal levels due to higher noise levels
or other equipment working in the same area).
Antenna alignment with Link test
It is recommended to use “Antenna alignment with Link test” procedure instead
of “Antenna alignment with MINT Monitor” procedure because Link test is much
better radio link testing tool then Mint Monitor. This is so because of the
following reasons:
ü With Link test tool you are getting much more testing statistics using only
one command.
