While RSSI is measured over full bandwidth, RSRP is measured over narrow bandwidth. RSRQ. This is in an area with good coverage where, a couple of seconds before and after, the command returns reasonable values. Ankur Tomar. 0 Release 15 4 ETSI TS 138 215 V15. 09 dBm. The chart below shows the relation between the value of RSRP and signal. The trajectories of 4G LTE RSRP, RSRQ, SINR, and PCC PHY Throughput performance distributions are as shown in Fig. Allow access through WAN. Signal strength, which is called RSRP in 4G LTE and 5G networks, definitely matters. The RRM functionalities comprise of a range. 37 dBm, with an average of − 93. The tested KPIs include the RSRP, RSRQ, RSSI, SINR, PCC PHY DL Throughput, and the PDCP DL Throughput. LTE covers a range of 3Mbps and falls just short of 4G speed. - Do 326Mbps (20MHz). The LTE ASU scale ranges between 0 and 95, with 0 as the least. The RSRP and RSRQ values are relevant when the modem type is in 4G/LTE. RSRQ to SINR. The blue boxes represent the data range, the red line represents the median, and the green diamond represents the mean value. The adopted thresholds related to the above mentioned UE measurements are the WLAN RSS Threshold and the LTE RSRP Threshold. w1-Threshold-r13 WLAN-RSSI-Range-r13 }, eventW2-r13 SEQUENCE. docx. 101. That is, they are all go through the 4 step message transaction (Msg1, Msg2, Msg3, Msg4). LogPerAntenna for RDF. This is the common key performance parameters for LTE drive test parameter we have to work out. 4 show the signal level both RSRP and SIR. However, in NR there is no CRS.
