*[[RSSI]] - Received Signal Strength Indicator. RSSI is a negative value, and the closer to 0, the stronger the signal
−
*[[EC/IO]] - indicates the downlink carrier-to-interference ratio (signal quality)
+
*[[EC/IO]] - indicates the downlink carrier-to-interference ratio (signal quality).EC/IO is a negative dBm value. Values closer to 0 are stronger signals
*[[RSCP]] - indicates the Received Signal Code Power
