SINR is a positive number the greater the value, the better quality the signal. 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. 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 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.) The table below shows recommended RSRP (Reference Signal Received Power) and RSRQ (Reference Signal. RSRP is usually a negative number, so −90 dBm RSRP is stronger than −100 dBm RSRP. See more on 4G Bands and 5G Bands in use in the U.S. The greater the RSRP value, the stronger the cellular signal. 4G LTE and 5G cell signal strength are measured by RSRP ( Reference Signal Received Power) in decibel-milliwatts ( dBm).
