With opmode off, run the “survey” command from the ss subdirectory. It may
be useful to run this command for one entire day or run several passes during
the course of a day to determine when interference may be occurring.
Analyze the results which show which channels and polarizations have the
lowest received signal strength, indicating they are good candidates for usage.
Once a channel and polarization have been selected verify that the expected
signal strength levels are being achieved with SUs in the coverage area.
Run the “cf2cf” test with an SU in the coverage area. Verify that there are no
packets being lost except by the AP. Typical numbers vary with packet size and
transmission distance, but as an example, with 1600 byte packets at under 1
mile, the numbers of packets received by both ends should be about 340. The
AP should detect about 320 good packets. The HR and CR should all be zero.
This indicates an error free link.
Adjust the RSSItarget, service range, rfrxthreshold as appropriate.
Activate service by changing opmode to AP.
Another useful command to determine if any M5800S series APs are active in
the area is the “apsearch” command. It can be run from either an AP or SU
and will force the radio to listen for packets being transmitted from an AP,
then report the results with signal strengths. See Command Set Reference
Manual for more information.
