A Drive Test is a field measurement method that collects mobile network radio KPIs (RSRP, RSRQ, SINR, throughput) from a vehicle in motion. It evaluates coverage, quality of service and network performance along a given route, with all measurements GPS-geolocated.
What is a Drive Test?
The reference method for evaluating mobile network coverage and quality in the field.
Detailed explanation
A Drive Test involves traversing a predetermined route in a vehicle while automatically collecting radio measurements from the mobile network. A terminal equipped with measurement software continuously records radio KPIs (RSRP, RSRQ, SINR, RSSI), throughput data, latency and network events such as handovers and call drops.
Each measurement is tagged with GPS coordinates, enabling the generation of geolocated coverage maps. These maps identify dead zones (no signal), grey zones (insufficient signal) and problematic handover points. Drive Tests are used by operators for new site validation, competitive benchmarking and ongoing network optimization.
Historically, Drive Tests required dedicated expensive equipment (scanners, professional terminals) and specially outfitted vehicles. Today, smartphone-based solutions allow professional Drive Test campaigns using a standard Android device with the Qualcomm diagnostic interface, significantly reducing cost and logistical complexity.
A typical Drive Test follows a structured protocol: route definition, measurement parameter configuration, field data collection, then post-processing analysis. Results inform optimization decisions such as antenna tilt adjustments, handover parameter tuning or small cell deployment in low-coverage areas.
KPIs collected during a Drive Test
| KPI | Description | Usage |
|---|---|---|
| RSRP | Reference signal power | Coverage |
| SINR | Signal-to-interference ratio | Radio quality |
| Throughput | DL/UL data rate | Performance |
| Handover | Cell-to-cell transfers | Mobility |
