RSRP measures the power of the reference signal and helps indicate coverage strength. RSRQ combines signal and interference effects to describe quality, while SINR compares the wanted signal with interference and noise. Together they provide a much better picture than bars alone.
A strong RSRP with poor SINR can indicate interference or congestion, so a higher-gain antenna may not fix the problem. A weaker but cleaner signal may deliver better performance. Values and thresholds vary by technology and modem, so use them comparatively while changing antenna position, band or tower, and confirm the final result with real traffic.
