There are two major areas for possible improvement—the radio and the
data network. The following sections will provide you with a variety of
items to check and on many occasions, ways to correct or improve their
performance.
The menu/screen shown in Figure 2-48 is one of two primary sources of
information on the radio layer and radio network performance.

•
RF Output Power
(Display only)
—Measured power output.
(See “ How Much Output Power Can be Used?” on Page 135)
•
Signal-to-Noise
(Display only)
—Current running-average SNR
value all active operating frequencies.
(No value displayed on APs)
NOTE:
The RSSI is an average of the last 20 RSSI samples. The RSSI
value is reset every time the radio returns to scanning mode.
•
(Display only)
—Current running-average Received Signal
Strength Indication for all active operating frequencies.
(No value displayed on APs.)
•
Actual Data Rate
(Display only)
—Over-the-air transmission rate (as
opposed to selected data rate) for the remote being monitored.
The fastest data rates can generally be achieved with stronger
signal levels.
•
RSSI by Zone
—Received Signal Strength Indicator by Zone.
(See “ RSSI by Zone Menu (Remotes Only)” on Page 86)
•
Event Log
—Access the menu for managing the unit’s log of
operational activities.(See “ Authorization Key —Alter the
unit’s overall capabilities by enabling the built-in resources.
