RSSI by Zone Menu
(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.
