6.5.2 Aiming Directive Antennas for Maximum RSSI

The wireless network integrity depends, in a large part, on stable radio 
signal levels being received at each end of a data link. In general, signal 
levels stronger than –90 dBm provide the basis for reliable 
communication that includes a 15 dB fade margin. As the distance 
between the AP and Remotes increases, the influence of terrain, foliage, 
and man-made obstructions become more influential, and the use of 
directional antennas at remote locations becomes necessary. Directional 
antennas usually require some fine-tuning of their bearing to optimize 
the received signal strength. The transceiver has a built-in received 
signal strength indicator (RSSI) that you can use to tell when the antenna 
is in a position that provides the optimum received signal.

RSSI measurements and Wireless Packet Statistics are based on multiple 
samples over a period of several seconds. The average of these 
measurements is displayed by the entraNET MS.

The measurement and antenna alignment process usually takes 10 or 
more minutes at each transceiver.

The path to the 

Management System Menu

 item is shown in bold text 

below each step of the procedure.

Procedure

1. Verify that the Remote is associated with an AP radio. Observe the 

condition of the 

LINK

 LED.

LINK LED = on or blinking

This indicates that you have an adequate signal level for the 
measurements, and it is safe to proceed.

2. View and record the 

Radio Retries

 and 

No Ack

 

counts on the 

Radio 

Packet Statistics Screen

 (

Figure 3-45 on Page 81

). This information 

will be used later.

3. Clear the 

Radio Statistics

 history.

4. Read the RSSI level at the Remote

 (RADIO RSSI=).

5. Optimize the RSSI by slowly adjusting the direction of the antenna 

and watching for a peak in received signal strength. Get the RSSI 
indication several times after making each adjustment, so that the 
RSSI accurately reflects any change in the link signal strength. The 
higher the indication (less negative), the stronger the signal level 
(that is, –60 is better than –70).
