It is also helpful to check the RSSI of incoming signals. If the RSSI levels in each zone are
within a few decibels (dB) of each other, but less than –90 dBm, then check the aiming of the
antenna system. See “Aiming Directive Antennas for Maximum RSSI” in chapter 6 for details.

The average signal level should be –95 dBm or stronger for reliable performance with an
allowance for fade margin.

Another place to look for trouble is in Packets Received by Zone. The packets should be
evenly distributed across all zones (1-5% variation). If they are not, interference in the
disparate zones should be suspected. Blocking these zones may eliminate or reduce harmful
interference.
