Signal to Interference plus Noise (SINR) is yet another measure of the quality of the cellular connection.Reference Signal Received Quality (RSRQ) aims to describe the quality of the received signal, and takes into account the RSSI, RSRP, and how much of the available bandwidth is used.In our 4G Cloud Connectors, RSRP is nearly directly proportional to RSSI. Reference Signal Received Power (RSRP) is a 4G-specific measurement that represents the average power of cell-specific reference signals.The three metrics of interest are RSRP, RSRQ, and SINR. The cellular modems used in our 4G Cloud Connectors report several other metrics related to the cellular connection in addition to RSSI (Received Signal Strength Indicator). Low signal strengths will still be able to deliver a robust cellular connection.

Still, this doesn't tell us whether -130 is good enough.Cellular signal strength between 20–60% is considered normal However, if we were talking about a noise measurement, -130 would be better than -50. Radio signal strength/signal quality measurements are particularly tricky, as strength and quality are affected by even small changes in the local receiving environment - moving as little as a few inches or slightly changing the angle of the receiving antenna can make a huge difference.Ĭonsider the comments about whether -130 should be considered 'lower' or 'less negative.' In the case of signal strength, -50 is a stronger signal (better) than -130. But an end-user can latch onto one or two measurements out of the bunch and decide they have a problem. Unless you know what every measurement means and how various measurements interrelate, it's nearly useless. It's not a go/no-go test, it's quantitative measurement.

Yep, because this is a clear case of 'a little knowledge is a dangerous thing.' It's the kind of info one might see in a professional telecommunications test instrument. We need a manual for this field test so people can understand exactly what is what!
