from publication: 5G Based on MNOs for Critical Railway. SINR is a positive number the greater the value, the better quality the signal. Download scientific diagram RSRP, RSRQ and SINR measured CDF for 4G (right) and 5G (left). RSRP in NrUePhy::ReportRsReceivedPower and NrUePhy::ReceivePss. These measurements are used for the signal strength reporting criteria, signal strength thresholds, and signal levels functions. Even a small increase in RSRQ can result in a significant improvement in cellular data rates.Īlthough SINR ( Signal to Interference-plus Noise Ratio) is not included in the 3GPP mobile broadband specifications, some equipment manufacturers use this traditional way of measuring the ratio of signal to noise. Public group for discussing 5G-LENA topics. For devices running Android 11 or higher, the following signal measurement types are customizable for NGRAN (5G LTE) and EUTRAN (4G LTE) networks. A cell signal booster can’t improve the quality (RSRQ) of the signal, but an outside directional antenna ( an LPDA or a Yagi) can isolate a specific cell tower and help reduce interference from other nearby towers. Like RSRP, RSRQ is a negative number therefore, −8 dB RSRQ is higher-quality signal than −12 dB RSRQ.Ĭell signal boosters amplify the strength (RSRP) of the ambient cell signal available at the outside antenna. The greater the RSRQ value, the less interference the signal is getting from other cells operating at or near the same channel. Cell signal qualityĤG LTE and 5G cell signal quality are measured by RSRQ ( Reference Signal Received Quality) in decibels ( dB). Increasing the strength of a poor-quality signal is like turning up the volume on a television that’s only producing static-all you get is louder static. Signal strength is important, but it’s only as good as the quality of the signal itself. ( Learn more about cell signal strength and how to measure it here.) RSRP is usually a negative number, so −90 dBm RSRP is stronger than −100 dBm RSRP. The greater the RSRP value, the stronger the cellular signal. RSRQ Indicates quality of the received signal, and its range is typically -19.5dB (bad) to -3dB (good). 4G LTE and 5G cell signal strength are measured by RSRP ( Reference Signal Received Power) in decibel-milliwatts ( dBm). RSRP The average power received from a single Reference signal, and Its typical range is around -44dbm (good) to -140dbm (bad).
