![]() This page will explain about various aspect of Measurement Process that is happening in a LTE. ![]() As RSRQ combines signal strength as well as interference level, this measurement value provides additional help for mobility decisions. 4G/LTE - Measurement Multi Cell Measurement. ![]() RSSI is the total received wideband power including all interference and thermal noise. Typical field values for RSRP range from -75 dBm close to site to -120 dBm at the edge of LTE coverage RSSI Reference Signal Strength Indicator The RSSI is calculated as a linear average of the total power measured across OFDMA symbols which contain Reference Symbols transmitted from the first antenna port (if MIMO is not used). RSRQ is the ratio between the RSRP and the Received Signal Strength Indicator (RSSI), and depending on the measurement bandwidth, means the number of resource blocks. The RSRQ measurement provides additional information when RSRP is not sufficient to make a reliable handover or cell reselection decision. It can therefore only be measured in the OFDM symbols carrying reference symbols. If your RSRP signal is stronger than around -100 dBm, then a stronger signal wont help increase your data rates. The signal strength of the LTE modem can also be determined using the SIGNAL STRENGTH indicators on the top panel of the device. But it’s often not the most important factor. RSRP (Reference Signal Received Power) - the average power of the received pilot signals (Reference Signal) or the level of the received signal from the Base Station. Signal strength, which is called RSRP in 4G LTE and 5G networks, definitely matters. The RSRP is the average of the power of all resource elements which carry cell-specific reference signals over the entire bandwidth. Signal Strength (RSRP) Many people think this is the most important factor, but it isnt. ![]() In LTE (includes CAT.M1 and NB IoT) signal strength. This measurement of the signal strength of an LTE cell helps to rank between the different cells as input for handover and cell reselection decisions. Median: -100 dbm RSRP -110 dbm, and -7dB RSRQ -11 dB Weak: RSRP < -115 dbm, or RSRQ < -11 dBb. The RSRP is comparable to the CPICH RSCP measurement in WCDMA. ![]()
