The values of RSRP range from -140 dBm to -44 dBm. 007 as returning: RSSI in the range -110 to -48 dBm for GSM, or RSCP in the range -120 to -27 dBm for WCDMA, or. RSSI is roughly equal to RSRP + 25. The range is 0-250 which translates to -20dB – +30dB. We need to know the performance of LTE mobile network in Sokaraja Tengah – Indonesia, which deployed by Telkomsel network provider by comparing its RSRP, SINR, RSRQ, and throughput using drive test method of Genex Probe. The UE takes the RSRP measurements and reports the results to the RNC through a receiver 48. The average power is a measure of the power received from a single reference signal. SINR=13. Under full Load condition the RSRP (dBm)= RSSI – 10*log (12*N) where N represents number of resource block. 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. Information about the signal power is given by the RSRP. This parameter is available for LTE mode. The signal levels of RSRP range from -10 dBm to -45 dBm while the signal levels of SIR range between 10 dB and 40 dB. But the actual power level used for this calculation needs to be RSSI. These thresholds define the required level of the UE measurement in order to select a given network. Overall protocol sequence of the process is made up of four messages, i. And for LTE, it returns only RSRP. Misalnya, modem 4G LTE mungkin melaporkan RSSI sebesar -68 dBm, tetapi: RSRP = -102 dBm. 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. RSSI untuk LTE dihitung dari beberapa pengukuran terkait sinyal lainnya: RSSI = wideband power = noise + serving cell power + interference power. RSCP. The LTE measurement and local topography profile data presented in this article were collected in Hatfield, Hertfordshire, United Kingdom (Latitude 51° 44׳ 56. 5G optimal values In the 5G modem web configurator on the NR7101 for example, navigate into System Monitor > Cellular info page, and you can view the current state of the. The mapping of measured quantity is defined in the table below: RSRP mapping 3GPP TS 36. This can happen immediately after the device is switched on, or it can happen after inter-system cell reselection from LTE. ; RSSI – Represents the entire received power including the wanted power from the serving cell as well as all. Fortunately, most of these areas are indoor areas. ≥ -90 dBm. And it does this for all three access technologies (GSM, WCDMA and LTE). 4 , the interference coming from the N-STAR c/d is negligible in indoor areas within the coverage of an LTE eNB or a small cell eNB. Reselection Criteria. Signal routerWireless site survey Rsrp lte values mapping rssi reported measurments measured betweenUnderstaning 4g signal strength. Range: 0-63The BSC6900 starts the timer to perform LTE cell measurements. An RSRP of -95dBm indicates a strong signal, whereas -115dBm. LogPerAntenna for RDF. What you should really do is find one place where you get a. 690 19223. The best reception is at RSRQ of − 3 dB. RSRP Frequency selective: Measure power on overall signal, i. figure 3Lte rsrp, rsrq and rssi measurments – tech trained Lte rsrp signal determined maximal diagrams right two anbieter infoRsrp rssi rsrq lte. 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. RSRP – The average power received from a single Reference signal, and Its typical range is around -44dbm (good) to -140dbm (bad). RSRP -94 dBm. - rsrp-ThresholdCSI-RS: This RSRP threshold is used for the selection of CSI-RS and corresponding Random Access Preamble and PRACH occasion.
