Drive Test
RF measurement campaign conducted while driving along routes with test equipment to validate coverage, quality, and identify network problem areas.
Drive testing is exactly what it sounds like — you put measurement gear in a car and drive defined routes to see what the network really does out in the field, not what the planning tool predicted. A typical rig is a scanner plus one or more test phones running a tool like TEMS or NEMO, all GPS-tagged so every sample lands on a map. You collect RSRP, RSRQ, SINR, throughput, plus the RRC and NAS signalling, then look for where reality and the plan diverge.
It's the ground truth for a lot of RF work: validating a new site after integration, hunting down dropped-call clusters, checking handover behaviour along a boundary, or benchmarking against a competitor. The honest downside is cost and reach — it's slow, labour-intensive, only covers roads, and gives you a snapshot rather than continuous coverage. That's precisely why operators lean on MDT (network-reported measurements from real handsets) to fill the gaps. Drive testing isn't going away, but it's increasingly the targeted tool you reach for when you need to physically be somewhere, not the blanket method it once was.
Frequently asked questions
- Is drive testing being replaced by MDT?
- Reduced, not replaced. MDT (Minimization of Drive Tests) collects measurements from real subscribers' phones across the whole footprint and around the clock, which drive testing can never match for coverage or cost. But MDT data is anonymised, sampled, and lacks the controlled conditions and rich signalling of a dedicated rig. Operators use MDT for broad, continuous insight and keep drive testing for targeted, high-fidelity work like new-site acceptance, complaint hunting, and benchmarking.
