GWS measures mobile network performance by conducting controlled drive tests. GWS drives testing vehicles that contain mobile devices, which complete voice and data tasks. The testing vehicles drive along pre-determined routes to test multiple demographics.GWS also conducts walk and venue testing in high pedestrian areas and public events. Testing is done using backpacks with equipment similar to that used in their drive tests.
GWS generates reports on the voice and data results collected from network tests. The benchmarking reports analyze a wireless operator’s network performance over time across geographical markets.
