A very powerful feature of CoverMap is the possibility of “turning off” Base Stations,
by simply unchecking the check box next to the LA one wants to turn off (or click on
“none” or “all” to enable or disable all LAs). This means that the user can find out, what
would happen to their network, if one or even multiple base stations would fail.
Redundancy is of utmost importance in TETRA and the TETRA user should ensure that
even if one base station fails, the RSSI and reach of the neighbor base stations is strong
enough to cover that area in case of loss. In the picture and example below only one LA
is active. This is also an interesting feature to see the reach of each single base station
individually.

RSSI analysis/ RSSI good/bad
Another powerful feature of CoverMap is the “RSSI good/bad” feature. Once the user
has chosen the tick box next to this feature (in the top menu), the “RSSI threshold” field
in the top left corner will appear. Here the user can decide on an RSSI level, which they
find acceptable as the worst RSSI in their network and activate it. Once activated
CoverMap will evaluate the % of measurement points that were of equal or better value
than the chosen RSSI level, and will give the user a good clue on the average field
strength in their network. It will also change the color of the measurement points to
either red (equal or better value than the threshold) or white (worse than the threshold).
