Measuring directed RSSI

You may want to measure the Receive Signal Strength Indicator between a portable and a specific base station radio. For example, you may suspect that a radio in a base station is not working properly. You can also use directed Receive Signal Strength Indicator to prevent hand-off while you find a cell edge. To measure the Receive Signal Strength Indicator of a desired radio, you must be in range of two base stations—the one you want to measure, and another base station.

Receive Signal Strength Indicator applies to one radio in a base station.

You cannot measure the directed Receive Signal Strength Indicator of the other radio in the base station to which you are connected.
