For LTE networks, an RSRP value of about -80dBm shows excellent signal strength with maximum data speeds. 5dB(bad) to -3dB (good). RSSI – Represents the entire received power including the wanted power from the serving cell as well as all cochannel power and other sources of noise and it is related to the above parameters through the following formula: RSRQ=N*(RSRP. Serial, Revision, IMSI, Sim State, PIN state, GSM signal, WCDMA RSCP WCDMA EC/IO, LTE RSRP, LTE SINR, LTE RSRQ, CELL ID, Operator, Operator number, Connection type, Temperature, PIN count to Azure IoT Hub serverIn this 37 minute video, we discuss the technology of CBRS and how it relates to the unlicensed Wi-Fi we know as 802. 30%, RSRP values range from-80 dBm. ”. The basic idea on RSRP/RSRQ in NR is also similar to LTE RSRP / RSRQ.
