Val rssiValue = (signalStrength?.times(2))?.minus(113)Īnd again - this solution needs to be implemented only for devices which uses API < 29, because for newer versions there is a variable, which returns almost(if not fully) the same value. So to access this mSignalStrength private property I used reflection and then applied the formula from the source code.Įxtension for getting private property from the class: fun T.getPrivateProperty(name: String): R? =Īnd the calculation of approximate RSSI value from the code in the question: val signalStrength = signalStrengthLte.getPrivateProperty('mSignalStrength') After going through source code of CellSignalStrengthLte class - I found an old deprecated private field for the signal strength and the method to convert this signal to approximate RSSI value. Quality (RSRQ), Reference Signal Strength Indicator (RSSI) and throughput (uplink - UL and downlink.

In the end I wasn't able to convert RSRP to RSSI, but I have managed to get approximate RSSI value. Signal Received Power (RSRP), Reference Signal Received.
