Field workflow
LTE & 5G Drive Test Guide
Collect measurement context first; isolate RF, mobility and capacity hypotheses second.
Log the context available on the handset
Network Drive Test logs available cellular readings, serving-cell information and GPS on Android. The exact metrics depend on the Android release, modem, permissions and what the network exposes.
Read signal and quality together
Use the RSRP, RSRQ and SINR analyzer to structure interpretation. A good RSRP with poor throughput may suggest interference, load, scheduling, backhaul or device limits; correlate it with time, cell, bandwidth and test conditions.
Quick diagnosis
For an example scenario, RSRP −77 dBm, RSRQ −15 dB and SINR 2 dB may warrant checking neighbor energy, load and interference before changing transmit power. It is not a universal diagnosis.
Continue with good RSRP, poor throughput diagnostics, LTE signal-quality interpretation and LTE EARFCN calculation.
