SINR is the term for signal quality, and is measured in decibels (dB). An RSRP of -80 dBm or higher is generally considered strong signal.
For example, even if all other factors were equal, VZW 10 MHz LTE bandwidth RSSI would measure 3 dB greater than would Sprint 5 MHz LTE bandwidth RSSI. This is effectively the power of the booster, and a higher value (closer to zero) means a stronger signal. Here are a few takeaways about RSSI and RSRP as signal strength measurement techniques for LTE: RSSI varies with LTE downlink bandwidth. In the case of physical barriers, it may be necessary to install an external antenna for a better signal if the building itself is not conducive to a strong signal. RSRP is the term for signal strength, measured in decibels milliwatts (dBm). In the above examples for instance, you could have excellent RF readings on all values, but if a tower is overloaded with users the carriers will load balance how much bandwidth each user is allowed and your overall throughput could be affected. Weather (cellular is essentially just radio waves and can be impacted by severe weather) Physical (buildings and building material types, mountains, semi-trucks with trailers, trains, large bodies of water can all impede the signal potentially) (the further from the tower, the weaker the overall RF will be Load on the tower (the more users on a given tower, the less overall bandwidth that will be available, regardless of signal quality and strength) Below is a list of the most common factors outside of the RF readings that will affect quality of the connection and throughput. There are several things to consider when measuring the quality outside of just the RF readings.
