Measuring RSSI for a C3050
The Receive Signal Strength Indicator (RSSI) is a
measurement of the signal strength the base station receives
from the portable. The base station controls the power
transmitting mode of the portable. When the base station
receives a weak signal, it instructs the portable to transmit in
high-power. When the base station receives a strong signal, it
instructs the portable to transmit in low-power. The strongest
RSSI value the portable displays is
-45
dBm (in the US) and
-44
dBm (in Canada). The weakest RSSI value the portable
displays is approximately
-94
to
-100
dBm.
To measure undirected RSSI
You can measure the signal strength between a portable and a
system-selected base station radio using undirected RSSI.
1. Open the portable flap.
2. Press
ñ
or
L
.
3. Press
¡¥»¥
. The portable displays the radio
ID of the base station that the portable is linked to,
followed by the signal strength, for example
03142 - 54
.
Hand-off occurs normally between the cell boundaries.
In this example, the module is
03
, the port is
14
, and the
radio is
2
. The signal strength measured by the base station
is
-54
dBm.
