![]() Reliable data speeds may be attained, but marginal data with drop-outs is possible. When this value gets close to -20, performance will drop drastically When this value gets close to -100, performance will drop drastically RSSI RSSIįair but useful, fast and reliable data speeds may be attained, but marginal data with drop-outs is possible RSSI is displayed as a negative number from 0dBm, being the best/strongest signal, to -110dBm, being the weakest or no signal. RSSI is used when measuring the strength of 3G networks. And using our graph once more, RSRP measures the RF power effectively of what is highlighted in red: Since the logarithmic ratio of 100 subcarriers to one subcarrier is 20 dB (e.g. RSSI is an abbreviation for Received Signal Strength Indicator and is a measure of cellular signal strength. As such, RSRP measurement bandwidth is the equivalent of only a single subcarrier. RSRP and RSRQ are two of the most important performance indicators a modem utilizes when accessing a network. In cellular networks, when a mobile moves from cell to cell and performs cell selection/reselection and handover, it has to measure the signal strength/quality of the neighbor cells. A few acronyms that you will encounter frequently are RSSI, RSRP, RSRQ and SINR, regardless of whether you are installing and managing a cellular router or deploying a cellular signal booster or amplifier system. RSRP and RSRQ are key measures of signal level and quality for modern LTE networks.
