However, in general we observed that the RSRP was generally better for NB-IoT than LTE-M. 0% 20% 40% 60% 80% 100%-15 -14 -13 -12 -11 -10 -9 -8. HUAWEI TECHNOLOGIES CO. Download : Download full-size image; Fig. RSSI is the total received wideband power including all interference and thermal noise. Below are explanations of the LTE signal strength parameters: SINR/SNR – The signal-to-noise ratio of the given signal. This parameter is available for LTE mode. The range is 0-250 which translates to -20dB – +30dB. The mapping of measured quantity is defined in the table – RSRP mapping. In the LTE system, a UE must detect and monitor the presence of multiple cells and perform cell reselection to ensure that it is "camped" on the most suitable cell. • It is defined as ratio of N x SS-RSRP/NR carrier RSSI. RSRP: RSRP – The average power received from a single Reference signal, and Its typical range is around -44dbm (good) to -140dbm (bad). RSRP Range (dBm) Signal Bar 3 vs RSRP Range Distribution. 11 or Wi-Fi 6. The handover procedure in LTE (Long-Term Evolution) networks involves the seamless transfer of a mobile device’s connection from one base station (eNodeB) to another while maintaining an ongoing communication session. 4G networks also operate within a limit of about -90dBm. In both cases, the CIO parameters raise the RSRP of the pico relative to the macros for processing of mobility events. RSRP does a better job of measuring signal power from a specific sector while potentially excluding noise and interference from other sectors. LTE In-band. HUAWEI TECHNOLOGIES CO. While dB is the expression of gain and is dimensionless, dBm meaning is a concrete measurement of the power level. Specifically, the dataset captured includes the Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Received Signal Strength Indicator (RSSI), Primary Component Carrier Signal-to-Interference-and-Noise Ratio (PCC SINR), Physical Cell Identity (PCI), Downlink E-UTRA Absolute Radio Frequency. Unchanged from their previous versions. To me, LTE-NB design concept seems closer to WCDMA MIB/SIB logic. RSRP stands for Reference Signal Received Power and RSRQ stands for Reference Signal Received Quality. This has a mild difference in. Respond to one ID in range [1;255] or any. > /interface lte cell-monitor lte1 PHY-CELLID BAND PSC EARFCN RSRP RSRQ RSSI SINR 49 B20 6300 -110dBm -19. 2. From the graph, the LTE ASU signal represented by RSRP in blue had a range between 30 and 70 RSRP. Based on the calculation results and drive test in Dayeuhkolot appeared RSRP range value from (-200) to (-61) dBm, SINR from (-11) to (27) dB and throughput of 1 Mbps to 11 Mbps with coverage of 10. RRM, SINR, RSRP, RSSI, RSRQ, Link Adaptation, Packet Scheduling, Throughput, Handover 1. Reference Signal Received Power (RSRP) is a measure of the received power level in an LTE cell network. Abnormal behavior directly pinpoints the problem, e. For NSA 5G, the control signaling is anchored to the 4G LTE network and requires a 4G LTE connection to establish before being able to. RSRP holds no meaning in GSM and RSSI means something different in LTE.
