RSRP does a better job of measuring signal power from a specific sector while potentially excluding noise and interference from other sectors. RSRP levels for usable signal typically range from about -75 dBm close in to an LTE cell site to -120 dBm at the edge of LTE coverage.
For example, lets say your Signal value is -55dBm and your Noise value is -95dBm. -55dBm + -95dBm = 40db this means you have an SNR of 40, the general rule of thumb is that any SNR above 20 is good. Other important terminologies that we need to understand is the EIRP and Free Space Path Loss.
