With the rapid development of the economy, more and more people buy small cars. People’s demand for driving technology training services, driver’s license training has become a popular way to learn a skill. Presently, all domestic driving license exams are completed using an information-based automatic assessment and scoring system, using 5G/4G VPN industrial routers to set up a 4G/5G/APN private network, which enables real-time monitoring, assessment, and scoring of test vehicles on-site by the testing center. It improves the standardization and efficiency of the test and also eliminates illegal bribery and cheating.
The driving test system has more stringent requirements for network reliability, real-time, security, and stability. In order to guarantee strict monitoring and assessment scoring in the test factory, many test centers use Alotcer 5G/4G APN intelligent driving test system solutions to provide stable, secure, and reliable information transmission.
