Measuring RSSI for a C3020 (Canada only)
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 -44 dBm. The weakest
RSSI value the portable displays is approximately -85 to -95
dBm.
