5G Signal Made Simple - What is RSSI, RSRP, RSRQ and SINR?

What is RSSI, RSRP, RSRQ and SINR - Dr Andre Fourie

RSSI - Received Signal Strength Indicator
RSRP - Reference Signal Received Power
RSRQ - Reference Signal Received Quality
SINR - signal-to-interference-plus-noise ratio
SNIR - Signal-to-noise-plus-interference ratio
SNR - Signal to Noise Ratio.

Poynting is a top global provider of integrated antenna solutions, responsible for the innovation, design and manufacture of its market-leading products. Established as a consultancy in 1990, Poynting evolved into an official PTY in 1997 and in 2001 established Poynting Antennas. Poynting supplies antenna solutions for primarily wireless high-speed data applications. We provide solutions for 3G/4G and LTE, GPS and GLONASS, IoT Lora and SigFOx as well as RFID and WIFI.

Our antennas are used in residential, automotive, industrial and IoT solutions. We also have specialised antenna solutions for the marine, mining and tunnelling markets.This Youtube channel showcases Poynting Antennas' products and technical knowledge. You will find a selection of RF (Radio Frequency) or EM (Electromagnetic Engineering) FAQ with their answers. We regularly show you our latest antenna releases with unboxing videos. Where possible we do internet speed tests where we show how the speed of your Broadband 3G or LTE connection increases by fitting a Poynting outdoor antenna to your router. Do you want to get more into the detail of our antennas and RF or antennas in general? Have a look at our webinars - A guide to antenna implementation & considerations and Getting to the Poynt - Antenna specification minefield.

Poynting innovates, designs and manufactures integrated antennas solutions primarily for wireless high-speed data applications such as 4G LTE residential as well as B2B, antenna solutions for GSM, M2M, DTV (digital TV) and other CPE applications within the telecommunication, broadcast and consumer market.

    No fancy digital white board, just quality information explaining the basics of radio signals. Shocking! ;)
  • @rthomas7928
    Great Video I'm trying to configure my directional antenna Currently with RSRP - 76dbm RSRQ - 10dbm SNR 6dm
  • @robfrankel5956
    Many thanks for this explanation, Dr Fourie. I am looking for some advice, please. I currently get excellent RSRP (-63dBm) but bad RSRQ (-10dB). From what I get from your clip, this basically means I receive a strong signal but with lots of noise. I get between 1-3Mbps download speeds, even though I am 200m from my closest tower with clear LoS and there are towers all around. I am trying to decide between an XPOL-1 to take advantage of the many towers in the area, or XPOL-2 aimed directly at the close tower. I'm leaning towards the XPOL-2, but would appreciate the opinion of an expert.
  • @LK-3000
    Thank you for a very clear explanation of all these. Mine wildly fluctuate from fair to poor to good. Usually at around 11am it goes from high speed to nonexistent. And then in the evening it goes back to being high speed. I think my provider is throttling.
  • @lakshmiswarna7885
    hi Andre Fourie... can you please give the information related to that rsrp and rsrq for lte.... is that values will varies according to internal and external antenna that are connected to hardware... if it varies like that means what is range for internal and external antenna
  • @simplytoddy2119
    Hi, I tried the pointing Omni xpol antenna however I haven't noticed much difference in rsrq and rsrp on my router however they are both in good ranges. However it appears that my SINR is really making my connection poor and drastically change. My SINR varies from -1db to 18db (at this figure I get very good speeds). Can you recommend a product that will help most with SINR? Thanks
  • @farawayskies
    Just got assigned some tasks at work dealing with telemetry data in a multi-billion dollar company. Somebody wish me luck, I don't got a god damn clue what I'm doing. Thanks for your video sir.
  • @rickmasten3293
    Current reading from mofi 4500 V4 RSRQ -74 RSRP -621 RSSI -350 I'm currently using a weboost yagi antenna 3314411 and a we boost panel antenna that's part of the FBA_470101 Kit mounted about 30ft in the air. I have these on a splitter going to a signal booster. Would it be better to have them going straight to the mofi? The yagi was also a 50 ohm N-connector but i took it a part and replced the pig tail with a 75 ohm F-type connector. I'm using at&t towers and i'm only a few miles away but in a dense foliage area.
  • @djrcchannel6496
    Wat do i do.. sinr of my parabolic antenna is poor sometimes average.. but rsrp and rsrq are good. Antenna height is 12 meters.
  • @andrewsudama4908
    I install wireless equipment in Toronto Canada, I work on Rogers wireless network. I currently install 2500mhz for 5g technology, we are getting alot of rssi alarms. I use low pim loads to find the issue. Issue is always appears when installed on antenna, do you have any suggestions on what it can be
  • @neetop1557
    Dr Fourie, I appreciate the material you put out. In a situation where RSRQ, RSRP and RSSI are in "excellent" range but SINR hovers between 0-9dB, which is close to "cell edge" i.e. "poor", how would that be explained? Is SINR still an important reference for LTE connections or should we look only at RSRQ (and RSRP for power)? That's what I'm understanding based on your explanation here.
  • @jasonashley9853
    Is it just me or is RSRP hard to get below -80 dbm most of the time? I average -80 - 96 dbm in my house and the tower is just a few houses down. Not very far. It appeared as though being a couple houses further down improved the signal even more. RSRQ is anywhere from -10 to -14 on average. What is 30 dB RSSNR mean?
  • @paulocarvalho914
    Trabalho com os níveis de sinal menor ou igual -85 dBm para a recepção da antena e ruído menor que -18 dB.
  • how do you improve them though`?
  • @biglonniegruhn
    I have the Mofi 4500 sim4 v3 and my rsrp -706, rssi -421, rsrq -103. How to Yagi outdoor antennas pointed at Verizon tower 1.3 miles due north of my home mounted to a pole 30+ feet in the air. Why are my numbers so horrible? Any help would be greatly appreciated.
