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-45dBm (in the US) and -44dBm (in Canada). The weakest RSSI value the portable displays is approximately -94to -100dBm.

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 Òor 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 -54dBm.

4.To end the connection, press ´or eor close the flap.
