Reference Signal Received Power (RSRP)

LTE and 5G measurement of the average power of reference signals from a cell, in dBm.

Definition

RSRP ranges from about -44 dBm (excellent) to -140 dBm (unusable), with values above about -90 dBm considered good. It is used with RSRQ and SINR for cell selection and handover. It is the cellular counterpart to Wi-Fi RSSI.

Exam tip

RSRP measures signal strength; RSRQ and SINR indicate quality.
