Highways inter spot speed detection---Erect a velocity measuring system in every few kilometers on the highway. Data was collected by the lens, and was sent to the CNC (Computer Numerical Control) center via wireless transportation after being calculated by the computer.

Wireless transmission system---When the front end speed data processed by the computer through a wireless network bridge which wirelessly transmitted to the nearest base station which is already existed. The base station side will also set up a wireless bridge, receive data from the front-end, and then introduce it to the computer room via cable.
