But before I give an example here, one important note: your phone measures signal strength in RSRP, which is dependent on the bandwidth of the signal. 133)Drive Test Parameters RSRP • RSRP :- Reference signal receive power. However, at what range is signal quality considered strong, moderate, weak, and poor and what these ranges mean in the. 54%. SS SINR = SS RSRP / SS_Interference. Inter-system LTE events B1 and B2 are based upon CPICH RSCP or CPICH Ec. Advanced_compact_test_range for Both Radome and. RSSI is measured over entire bandwidth of occupied RBs (Resource. , LTD. This is how a excellent RSRQ is calculated, now using same formula u can calculate for. Power Control" and if you want to have some hands-on experience of these, I would recommand you to try some test items on 36. 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. For LTE networks, an RSRP value of about -80dBm shows excellent signal strength with maximum data speeds. M fc0, fc1, fc2, fc3, is the latest measured result, F fc4, fc5, is the filtered result and the factor “a” is based on the filter Rsrp_Filter_Coefficient fc6, fc7, fc8, fc9, 4. Mid range, High range. There is a formula for each network and the simple formula for LTE is the ASU number subtracted by 141. As a result of determining that the UE is LTE-capable, a signal quality measurement requester 46 causes a transmitter 47 to transmit a request to the UE to take and report an RSRP measurement of LTE eNodeBs within range. RSRP (dBm) = RSSI (dBm) – 10*log (12*N) 2. the reporting range of RSRP is defined from -140 dBm to – 44 dBm with 1 dB resolution. 1. The signal strength of the LTE modem can also be determined using the SIGNAL STRENGTH indicators on the top panel of the device. Unchanged from their previous versions. 0 (2010-03) The reporting range of RSRP is defined from -140 dBm to – 44 dBm with 1 dB resolution. The reporting range of RSRQ is defined from -19. The minimum allowed RSRP in the 3GPP standard for LTE is -140 dBm, and -156 dBm in NR. LTE [Public Safety Communications]. Shows the signal strength (ss-rsrp) plot from 2. Usually routers have indicators if it means burning the maximum -90 dBm or higher (tends to zero). 5 dB resolution; RSRQ measurement report mapping (3GPP Reference: TS 36.
