This is the most important item UE has to measure for cell selection, reselection and handover. <lte_rsrq>: An integer. 970 12084. 3GPP devices will require a valid unlocked SIM card before any of the features in the interface can be used. Signal performance wasM RB is the number of resource blocks occupied in the downlink. Reporting range -44…-140 dBm; RSRP does a better job of measuring signal power from a specific sector while potentially excluding noise and interference from other sectors. The LTE measurement and local topography profile data presented in this article were collected in Hatfield, Hertfordshire, United Kingdom (Latitude 51° 44׳ 56. This range of signal is strong and will most likely offer reliable and good data speed. Simulation is conducted. Range: 0-65535 "-" Cannot get the invalid value <cellid> Hexadecimal format. There is for example following relationship between SINR and RSRQ (LTE only): There is also a relationship between SINR and RSSI (2G, 3G and LTE):The content of the LTE SIB24 is presented in Table 326. If signal quality is bad then I suggest that you call AT&T to test the signal. What is RSRP and RSRQ in LTE? RSRP and RSRQ are key measures of signal level and quality for. The maximum power for LTE (RSRP) at the antenna connection of user equipment is − 25 dBm. The RSRP range (-120, -100dBm) has a distribution of 28. LTE DRIVE TEST PARAMETERS RSRP :- Reference signal receive power. NB-IoT is a narrowband radio access technology reusing components from LTE. 4G/LTE - Basic Procedures Cell Reselection . 4G & 5G Interview Preparation: Why RSRP Range is -140dBm to -44dBm in LTE? Calculation 5G RSRP?. LTE Events A1, A2, A3, A4 and A5 are based upon either RSRP or RSRQ messages. It sends a non-negative value ranging from 0 to 34 and each of these values are mapped to a specific range of real RSRQ value as shown in the following table from 36. 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. Tabel 1 RSRP dan nilainya untuk parameter analisis drive test RSRP (dBm) Range Kategori RSRP >= -90 dan < 0 Good < -90 dan > -110 Fair <= -110 dan >= -150. In the first place, detailed collisions between FDD LTE and NR are presented and involved with physical control. We observe greater likelihood of lower velocities in rural and urban compared to semi-urban counties. 0 (2010-03) The reporting range of RSRP is defined from -140 dBm to – 44 dBm with 1 dB resolution. Revision, IMSI, SIM State, PIN state, GSM signal, WCDMA RSCP, WCDMA EC/IO, LTE RSRP, LTE SINR, LTE RSRQ, CELL ID, Operator, Operator number, Connection type. 65" W). This is the dataset for the paper Bayesian Inference of Sector Orientation in LTE Networks based on End-User Measurements published at VTC 2021 - Fall. This interface provides access to extended signal quality information. A minimum of -20 dB SINR (of the S-Synch channel) is needed to detect RSRP/RSRQ. This is the common key performance parameters for LTE drive test parameter we have to work out for LTE drive test task.
