In this page we present a simple LTE RSRP & RSRQ calculator. The calculation is performed based on RSSI and channel Bandwidth considered. The formulas used in within the calculator is below, where:

• • • RSRP is the Reference Signal Received Power and is measured in a single RE of the LTE REsource Block. Hence, RSRP is also called as average received power of a single reference signal RE (Resource Element)
    • RSRQ is the Reference Signal Received Quality
    • RSSI is measured over entire bandwidth of occupied RBs (Resource Blocks)

LTE RSRP and RSRQ CALCULATOR EXAMPLE:

• • • Input : BW = 10 MHz , RSSI = -79 dBm
    • Outputs : RSRP (dBm) = -106.78 dBm ; RSRQ (dBm) = -10.79dBm ; PRBs/BW = 50

LTE RSRP and RSRQ CALCULATOR formula or equations

Following equations are used in the calculator:

RSRP=RSSI – 10LOG(12*N)

RSRQ = N*(RSRP/RSSI) or RSRQ = 10LO(N) + RSRP(dBm) – RSSI(dBm)

Where:

• • • N = Number of RBs as per Channel Bandwidth
      • N=6 for  1.4 MHz
      • N=15 for 3 MHz
      • N=25 for 5 MHz
      • N=50 for 10MHz
      • N=75 for 15 MHz
      • N=100 for 20MHz
    • RSRP= Average Received Signal Power of a a Singel Resource Element (RE) – In LTE there are 84 RE in a single RB
    • RSRQ=Power measured over the entire BW of occuped RBs
