What is RSRP and RSRQ in LTE?

RSRP and RSRQ are key measures of signal level and quality for modern LTE networks. In LTE network, a UE measures two parameters on reference signal: RSRP (Reference Signal Received Power) and RSRQ (Reference Signal Received Quality).

What is a good RSRQ signal?

Reference Signals Received Power (RSRP) and Reference Signals Received Quality (RSRQ) are indications of your signal performance. For RSRP, -80 dBm is an excellent signal whereas -100 dBm is no signal. For RSRQ, -10 dB is an excellent signal, whereas -20 dB is no signal.

What does RSRP mean?

Reference Signal Received Power (RSRP) is a measurement of the received power level in an LTE cell network. The average power is a measurement of the power received from a single reference signal.

What is a good RSRP value 5g?

about -3 dB
3GPP has provided a table shown below, by using this table the integer value can be translated to a range of RSRP value in dB. The best value of RSRP is about -3 dB and worst value can be -19.5dB.

What is a good Sinr value in LTE?

4G (LTE)

SINR Signal strength
>= 20 dB Excellent
13 dB to 20 dB Good
0 dB to 13 dB Fair to poor
<= 0 dB No signal

What is Rsrq signal strength?

RSRQ – Indicates quality of the received signal, and its range is typically -19.5dB(bad) to -3dB (good).

How do I improve my RSRP signal strength?

How Can I Improve My 4G LTE or 5G Speed?

  1. Get a New Phone/Hotspot. If you’re using an old device, a new phone or hotspot may allow you to connect to new bands.
  2. Use External Antennas. Many hotspots from major carriers like AT, Verizon, Sprint and T-Mobile support external antenna ports.
  3. Use a Signal Booster.

How can I improve my RSRP in LTE?

How can I improve my LTE signal quality?

Why is Sinr bad in LTE?

SINR = -1.8 dB In this case, the signal quality is actually very poor. This could be due to the device being some distance away from the LTE transmitter. It’s also possible that something is interfering with the signal, such as a building or other obstructions between the device and the tower.

What’s the difference between RSRP and RSRQ in LTE?

RSRP – Reference Signal Received Power: RSRP is a RSSI type of measurement, as follows there are some definition of it and some details as well. It is the power of the LTE Reference Signals spread over the full bandwidth and narrowband. A minimum of -20 dB SINR (of the S-Synch channel) is needed to detect RSRP/RSRQ.

What are the values of RSRP and RSRQ?

RSRP – The average power received from a single Reference signal, and Its typical range is around -44dbm (good) to -140dbm (bad). RSRQ – Indicates quality of the received signal, and its range is typically -19.5dB (bad) to -3dB (good). Where N is the number of Resource Blocks of the E-UTRA carrier RSSI measurement bandwidth.

What does RSRQ stand for in signal strength?

RSRQ depends on serving cell power and the number of Tx antennas. RSRQ – Reference Signal Received Quality. RSRQ is a C/I type of measurement and it indicates the quality of the received reference signal. The RSRQ measurement provides additional information when RSRP is not sufficient to make a reliable handover or cell re-selection decision.

What does RSSI and RSRP mean on a cell phone?

A cellular router or cellular amplifier may show an RSSI of -70dBm, which would be a strong connection. RSRP is short for Reference Signal Received Power, used when measuring 4G LTE networks. A cell phone, or other LTE equipped device would display signal strength in RSRP, measured from 0dBm (weakest) to -120dBm (weakest/no signal).
