Driving Test Network Solution

Background
Nowadays, private car ownership has become increasingly widespread among households. With the growth in the number of automobiles, the demand for driver's licenses has also been steadily increasing. Faced with a large influx of people, traditional driving school exams have exposed numerous shortcomings. For instance, the car-mounted monitoring information and data transmission of the third-stage exam system require the deployment of high-power Wi-Fi base stations along the exam route. The use of 4G signals as a wireless communication medium is becoming more widespread across various industries.

With the implementation of the new road test method for the third-stage exam, electronic road tests that rely on direct assessment of candidates' exam actions, including the distribution of candidate information to exam vehicles, the transmission of exam videos, and the connectivity between exam vehicles and databases, have been fully implemented.
