![]() Quality is calculated over all data in the Measurement Interval. Carrier RSSI (Received Signal Strength Indicator) depending on its frequency assignment and application. 10 × log 100 20), RSSI tends to measure about 20 dB higher than does RSRP. And using our graph once more, RSRP measures the RF power effectively of what is highlighted in red: Since the logarithmic ratio of 100 subcarriers to one subcarrier is 20 dB (e.g. This ASU number can be converted to the received dbm value. As such, RSRP measurement bandwidth is the equivalent of only a single subcarrier. It is a value proportional to the received signal strength measured by the mobile phone. It is a measurement of received power on an LTE network and is given as an ASU - Arbitrary Strength Unit - number. or TDD Time Division Duplex: A duplexing technique dividing a radio channel in time to allow downlink operation during part of the frame period and uplink operation in the remainder of the frame period. RSRP means Reference Signal Received Power. In LTE (includes CAT.M1 and NB IoT) signal strength. This system uses DSSS and either FDD Frequency Division Duplex: A duplex scheme in which uplink and downlink transmissions use different frequencies but are typically simultaneous. Median: -100 dbm RSRP -110 dbm, and -7dB RSRQ -11 dB Weak: RSRP < -115 dbm, or RSRQ < -11 dBb. N = number of resource blocks over which RSRP and RSSI are calculated (the LTE Long Term Evolution demodulator includes all resource blocks in the frame bandwidth)Į- UTRA UMTS Terrestrial Radio Access: A W-CDMA standard developed ETSI, ARIB and the TIA Telecommunications IndustryĪssociation (U.S.): One of the Telecommunications standards setting bodies in the United States. ![]() RSRQ = N * RSRP / ( E-UTRA Evolved Universal Terrestrial Radio Access Carrier RSSI Received signal strength indication) Quality, or RSRQ, is a measure of the quality of the received signal as defined in Section 5.1.3 of 3GPP TS Technical Specification 36.214 and is given by the following equation ![]() Menu Path: Trace > Data > Demod > Error Summary ![]()
