Problems solved by technology

For the high incidence and real-time requirements of the timing process, some traditional timing methods such as network timing are difficult to meet
For a system that is often on the move, such as automatic driving, the long-distance timing method is often affected by the signal strength, and it is also difficult to meet the real-time timing requirements.
