RSRP

Reference signal received power is the LTE signal-strength measurement in dBm that field teams compare, unlike the bars a device shows.

Definitions only — a term explained here is not a service we sell.

Reference signal received power (RSRP) is the average power of LTE cell-specific reference signals, measured in dBm. It is a defined, repeatable reading, while bars are a vendor-specific summary, so coverage work compares RSRP values.

The scale is logarithmic: -80 dBm is stronger than -110 dBm, and 10 dB is a tenfold change in power.

What the reading leaves out

RSRP alone does not describe quality. RSRQ and SINR show interference and load, so a strong reading with poor quality can still deliver badly. Record the band, the cell identity and the time with each reading.

LTE

Five RSRP marks on a dBm scale, from weak to strong.
Text description

The marks run from -120 dBm at the weak end to -70 dBm at the strong end. The grades are field guidance, not a specification, and shift with device and service.

Check the installation first

Check the antenna, the cable, the enclosure and the band support before replacing a module. Take the reading at the installed position, not on a bench. The Signal checker grades a reading and explains what to check next.

FAQ

Is RSRP the same as signal bars?

No. Bars are a vendor-specific summary; RSRP is a defined measurement in dBm, so readings compare across devices.

What is a good RSRP?

Above -90 dBm is generally good and above -80 dBm is excellent, as common field guidance rather than a 3GPP specification. The right threshold depends on the device, the band and the application.

Does RSRP include interference?

No. RSRP measures received power; RSRQ and SINR describe quality and interference, so read them together.
