![]() ![]() An RSRP of -95dBm indicates a strong signal, whereas -115dBm indicates a poor signal. ![]() A mobile phone or other LTE-enabled devices would display signal strength in RSRP, with values ranging from 0dBm (weakest) to -120dBm (weakest/no signal). RSRP is an abbreviation for Reference Signal Received Power, which is used for measuring 4G LTE networks. A cellular router or cellular amplifier with an RSSI of -70dBm indicates a good connection. RSSI is a metric used to assess the strength of 3G networks. RSSI is shown as a negative value ranging from 0dBm (best signal) to -110dBm (worst/no signal). RSSI (Received Signal Strength Indicator) is a cellular signal strength indicator. They are RSSI, RSRP, and RSRQ that you may be confused about them. There are a few acronyms that you will commonly see when installing and managing a cellular router or deploying a cellular signal booster or amplifier system. How to improve RSRP signal strength? Understanding RSRP, RSSI, and RSRQ So, How to improve RSRP - measurement of cellular signal strength? People pick cellular for a variety of reasons, including the cost of wireless broadband, but most commonly because cell service is simply the quickest alternative accessible in rural regions. Many families choose 4G or 5G cellular access over cable or fiber Internet. UE Measured RSRP equals to: Power from antenna – Path Loss = 25.2 – 128 = -102.It is so bad when seeing a slow-loading site or waiting for a buffering video. Let’s imagine Path Loss as 128dB in the UE location, then: Power from antenna: Power + Antenna Gain – Feeder Loss = 12.2 + 16 – 3 = 25.2dBm So based on calculation, transmission power for each Resource Element is 12.2dBm Number of subcarriers: 1200 (there are 1200 subcarriers in 20 MHz) In this example we will see theoretical calculation of RSRP: ![]() UE measures all the reference signals which are carried by resource elements and makes an average of measurements to obtain an RSRP value. It is equivalent of CPICH Power in WCDMA. RSRP is used for cell selection, cell reselection and handover purposes in LTE. The Reference Signal is carried by Resource Elements (RE). ![]() Reference Signal Received Power or with abbreviated version RSRP is linear averaged signal strength of Reference Signal. ![]()
