3.13.1Proper Operation—What to Look For
Table 3-12 and Table 3-13 on Page 143 show target performance values
for AP and Remote transceivers. View these values using the built-in
menu system by navigating the path shown under each table title.
For Optimal Sensitivity
(Trades off throughput for best possible sensitivity. AP more susceptible to interference)

-80 N/A dBm Sets AP receiver for highest gain.
When Heavy Interference Exists at AP
(Trades off range for robustness in the face of interference)
AP Remote Units Notes

Power
-60 N/A dBm Sets AP receiver for low gain,
which forces Remote transmit
power to be high.
For Mobile Systems
(Where hand-offs between APs are required)

Connection Status Associated Remote must be associated
for network operation.
Transmit Power Varies Adjusts automatically as
requested by AP.
RSSI
(Received Signal
Strength Indication)
Varies The less negative an RSSI
reading, the stronger the
signal (i.e., -75 dBm is
stronger than -85 dBm).
