Lte rsrp6/12/2023 Reliable data speeds may be attained, but marginal data with drop-outs is possible. When this value gets close to -100, performance will drop drastically ![]() RSRQ In dB, Indicates quality of the received signal, and its the ratio of usable signal to noise and interference measured in dBm. You can find more information on RSRP and RSRQ values in the 4G (LTE) section of the Mobile Signal Strength Recommendations page. RSRP The average power received from a single Reference signal, and Its typical range is around -44dbm (good) to -140dbm (bad). The RSRQ measurement provides additional information when RSRP is not sufficient to make a reliable handover or cell reselection decision. Remember those aforementioned and depicted 100 subcarriers that contain reference signals To calculate RSRP, the power in each one of those subcarriers is averaged. RSRQ is a C/I type of measurement and it indicates the quality of the received reference signal. RSRP, on the other hand, is an LTE specific metric that averages the RF power in all of the reference signals in the passband. RSRQ – Reference Signal Received Quality: Quality considering also RSSI and the number of used Resource Blocks (N) RSRQ = (N * RSRP) / RSSI measured over the same bandwidth. management (visibility into the LTE specifics: RSSI, RSRP, RSRQ, SNR). A minimum of -20 dB SINR (of the S-Synch channel) is needed to detect RSRP/RSRQ. LTE Antenna Installation, Positioning and Selection Guide for ISR and CGR Using. It is the power of the LTE Reference Signals spread over the full bandwidth and narrowband. RSRP – Reference Signal Received Power is an RSSI type of measurement. ![]() In the procedure of handover, the LTE specification provides the flexibility of using RSRP, RSRQ, or both. In cellular networks, when a mobile device moves from cell to cell and performs cell selection/reselection and handover, it has to measure the signal strength/quality of the neighbor cells. Reference Signals Received Power (RSRP) and Reference Signal Received Quality (RSRQ) are key measures of signal level and quality for modern LTE networks.
