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 Ò or L.
3. Press °•ª•. 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.
4. To end the connection, press ´ or e or close the
flap.
