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
- N = Number of RBs as per Channel Bandwidth

Calculator does not work. No ouptut
Hello Ben, thanks lot to inform us about this bug. We just finish to fix it!
Let’s play with it!
Calculator still doesn’t work.
Hi, Calculator is working fine. Please confirm, us.
I’m using CloudRF to generate coverage map and do path profile analysis between Tx & RX. As result, the received power at Rx is -64.5dBm. I’m not sure whether that value is RSSI or not. What your opinion? For your information, LTE channel bandwidth = 20MHz.
Hello, how can I answert you here without try to simulate the coverage and without know all boundaries conditions? 🙂
Hi….I would like to ask if the NR calculation same formula as LTE for SS-RSRP/SS-RSRQ/SS-RSSI?
Please explain more in details what you are looking for.
