Static Ignition: vehicle is stationary and the ignition is on, the DAB radio effect in the car is tested.
Dynamic Testing: Vehicle dynamics, DAB radio effect test in the car.
Reception Effect: Comparative test of DAB radio effects in various local frequency bands.
Low frequency interference test. Interference test for walkie-talkies and interference test in special environments such as near the airport.

Road Test：
Established short-distance and long-distance test routes include areas with strong interference near the airport and areas with poor signal in the suburbs.
