RSSI measurements and Wireless Packet Statistics are based on mul-
tiple 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 8 on Page 24
). 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 re
fl
ects 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).
6. View the
Radio Retries
and
No Ack
counts at the point of maxi-
mum RSSI level. They should be the same or lower than the previ-
ous reading.
(Main Menu > Performance Information > Packet Statistics > Wire-
less Packet Statistics)
If the RSSI peak results in an increase in the
Radio Retries
and
No
Ack
counts, the antenna may be aimed at an undesired signal
source. Try a different antenna orientation.
