(Remotes Only)
This screen displays the strength of RF signals received from the cur-
rently associated Access Point.
Wireless network integrity depends partially on stable radio signal
levels being received at each end of a data link. In general, signal levels
stronger than –80 dBm will provide reliable communication that
includes a 15 dB fade margin.
If you find there is a poor signal level on one zone, check the Packet Sta-
tistics Menu section on Page 49 and record the values. Then, set the
questionable zone to “Skipped” in the Radio Configuration Menu (Page
29) and look for an improvement in the Packet Statistics error rates. If
there is none, return the Zone to “Active.”
RSSI measurements and Wireless Packet Statistics are based on mul-
tiple samples over a period of several seconds. The average of these
measurements will be displayed by the entraNET Management System.

TIP: Under normal circumstances, the signal levels in each zone should
be within a few decibels of each other. If you see one that is signif-
icantly lower or higher, it may be a sign of radio frequency inter-
ference from another signal source on the 900 MHz band.
See “Network Performance Notes” on Page 54 for further infor-
mation.
