RSRP (Reference Signal Received Power): RSRP measures the power level of the received reference signal in a particular cell. But the actual power level used for this calculation needs to be RSSI. These values can be viewed under the Reporting tab, either as a graph, or as textual health data. The range for SINR is around 20db as the excellent signal and 0dB as the poor signal, as shown in Table 1. Thus, at t =0,1,2,···, there are K n (t) UEs connected to the nth eNB such that P N n=1 K n (t) K. If your RSRP signal is stronger than around -100 dBm, then a stronger signal won't help increase your data rates. In LTE, UEs are specified to operate with a maximum uplink transmit power to 23dBm +/-2, called Power Class 3 (PC3). Reference Signal Received Power (RSRP) is a measure of the received power level in an LTE cell network. So, SS_RSRP and SS_SINR are important values. The best reception is at RSRQ of − 3 dB. RSRP (dBm) = 𝑃𝑜 𝑁 (1) where Po represents received power, N represents elements of the LTE signal. In LTE – as any wireless system – the performance has a direct relationship with the RF conditions at the time. When the timer expires, the BSC6900 stops measuring LTE cells. Hi, focusing in this part of your question: “L1 ss-rsrp range is -140 dBm to -44 dBm, while L3 ss-rsrp range is between -156 dBm and -31 dBm. RSRQ [dB] Best Cell's RSRQ VS4G/LTE - PHY Measurement RSSI(Recieved Signal Strength Indicator) RSSI is the total power UE observes across the whole band. 1) RSRP – Reference Signals Received Power은 RSSI 유형의 측정입니다. g. 65" W). LTE-M is the industry term used for the wide range of LTE features and the narrow bandwidth device category for the support of mMTC. For LTE-M we still had a connection at 12 km, but it was lost before hitting the 13 km mark. For LTE-M we still had a connection at 12 km, but it was lost before hitting the 13 km mark. We observe greater likelihood of lower velocities in rural and urban compared to semi-urban counties. RSRP levels for usable signal typically range from about -75 dBm close in to an LTE cell site to -120 dBm at the edge of LTE coverage.
