4G wireless router applications in smart bus WiFi network and video monitoring

Install one or more 4G wireless cellular routers on each bus. The device can provide WiFi access to passengers' smartphones and tablets, and staff also can store content such as movies, music, advertisements or online shopping on the router. Meanwhile, a camera installed inside the car can transmit the latest video monitoring information to the router.

Deploy wireless AP(TGAP-W610+) in the station. When the vehicle enters the station, the 4G wireless router in the car can communicate with the wireless AP of the station and update the contents stored in the 4G router. At the same time, video data in the 4G wireless router will be uploaded to the station AP, and the station staff knows what is happening in the car timely. For example, if a passenger calls the police and says there is a thief on the bus, the staff can know the actual situation of the scene by checking the uploaded video data.

Advantages of the program

The onboard 4G wireless router provides the dual 4G connection which can provide 4G access with high bandwidth.

WiFi adopts the IEEE802.11N technology, which provides high bandwidth communication and supports passengers' video-on-demand and other high-bandwidth communication applications.

Built-in GPS module provides real-time vehicle positioning information upload.

High-speed wireless communication technology ensures high-speed synchronization and update of vehicle information and ground information.

The EN50155 rail transit certification standard meets the requirement of stable operation under bad environment.

Industrial 4G router traffic flow information collection

Traffic flow information collection system collects road traffic flow, speed, occupancy rate, length of vehicle, vehicle spacing and other original traffic flow information through the front ground sense coil detection, video detection, microwave detection and other collection methods, then  integrate and statistically analyze the collected traffic flow data and transmit them to the command center through the transmission network.

1. Solution
