RF Drive Test Engineer Jobs

Drive testing is a method of measuring and assessing the coverage, capacity and Quality of Service (QoS) of a mobile radio network.
The technique consists of using a motor vehicle containing mobile radio network air interface measurement equipment that can detect and record a wide variety of the physical and virtual parameters of mobile cellular service in a given geographical area.
By measuring what a wireless network subscriber would experience in any specific area, wireless carriers can make directed changes to their networks that provide better coverage and service to their customers.
Drive testing requires a mobile vehicle outfitted with drive testing measurement equipment. The equipment are usually highly specialized electronic devices that interface to OEM mobile handsets. This ensures measurements are realistic and comparable to actual user experiences.
Network benchmarking
For benchmarking, sophisticated multi-channel tools such as Focus Infocom's DMTS and XGMA, DingLi Communications' Pilot Fleet, Ascom's Symphony, Rohde & Schwarz-SwissQual's Diversity Benchmarker or Keysight Nemo Invex II are used to measure several network technologies and service types simultaneously to very high accuracy, to provide directly comparable information regarding competitive strengths and weaknesses. Results from benchmarking activities, such a comparative coverage analysis or comparative data network speed analysis, are frequently used in marketing campaigns. Drive testing to gather network bench-marking data is the only way mobile network operators can collect accurate competitive data on the true level of their own and their competitors technical performance and quality levels.

Optimization and troubleshooting

Optimization and troubleshooting information is more typically used to aid in finding specific problems during the rollout phases of new networks or to observe specific problems reported by consumers during the operational phase of the network lifecycle. In this mode drive testing data is used to diagnose the root cause of specific, typically localized, network issues such as dropped calls or missing neighbour cell assignments.
