RSRP measures reference-signal power
RSRP is commonly used to compare LTE and 5G received power. It is useful for controlled comparisons, but it does not measure available network capacity.
RSRQ adds a quality signal
RSRQ can reveal that a connection with acceptable power is affected by interference or a busy radio environment. More negative values generally indicate poorer quality.
SINR compares signal with noise
Higher SINR is generally better. A low or negative result can explain unstable throughput even when RSRP looks reasonable.
Frequently asked questions
What is a good RSRP value?
Around -90 dBm or stronger is commonly considered good received power, while results below -110 dBm are generally weak.
What is a good SINR value?
A result above 20 dB is generally excellent. Values near or below 0 dB indicate that interference and noise are substantial.
Why is speed slow with good RSRP?
RSRQ, SINR, congestion, spectrum and tower backhaul can limit speed even when received power is strong.
