There is a formula for each network and the simple formula for LTE is the ASU number subtracted by 141. 1 ghz signal. sinyal berdasarkan parameter RSRP untuk LTE 800 Mhz, dan 1800 Mhz dan membuat peta hasil drive test menggunakan ArcMap. There are two different ways defined to use the. Test suites lte-fdmt-ff-mac-scheduler and lte-tdmt-ff-mac-scheduler create different test cases with a single eNB and several UEs, all having the same Radio Bearer specification, using the Frequency Domain Maximum Throughput (FDMT) scheduler and. 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. Joint RSRP-velocity distribution in different counties. RSRP Range (dBm) Signal Bar 3 vs RSRP Range Distribution. It’s not, however, a clear indication of how good the signal quality is. Energy per chip to interference power ratio (EC/IO) is a measure of the quality/cleanliness of the signal from the tower to the modem and indicates the signal-to-noise ratio. It encompasses weaker signals (-140dBm) in areas with poor coverage and stronger signals (-44dBm) in areas with excellent signal quality, similar to LTE. 1, Fig. 9. refer LTE RSRP vs RSRQ for more details. 1 [ 1], perform cell search to detect the cells which are present, and finally make RSRP measurements in order to perform cell reselection. RSRP does a good job of measuring signal power from a specific sector while excluding interference and noise from other sectors. e. Logarithmic value of SINR. Cellular devices will tend to select the strongest signal they hear. rsrp-ThresholdSSB RSRP-Range OPTIONAL, -- Need R. 4G/LTE - Test. RSRQ = -16 dB. The best reception is at RSRQ of − 3 dB. Alihadian93 April 21, 2023, 7:14am 10. the UE-related measurements in LTE such as SINR, RSRP, RSSI and RSRQ are illustrated as follows. RSRP levels for. rsrp-ThresholdSSB-SUL RSRP-Range OPTIONAL, --. It is worth noting that it is faster than 3G. Updated Below are explanations of the LTE signal strength parameters: SINR/SNR – The signal-to-noise ratio of the given signal. #CoverageParameter #DTparameter #RfOptimizationComment me here for doubts or send me an ema. 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. The RSRQ, - RSRP Range (dBm) Figure 1. 1 Physical non-synchronized random access procedure". 14. First, here's my code for getting lte rsrp (or other) values. PSS possible values can be 0,1,2 and SSS. It takes an average of the power of the cell signals that your phone is getting from the tower and shows how strong those signals are.
