Wireless network system for roadway scene

The invention discloses a wireless network system for roadway scenes, which is not provided with a central controller and a switch and can save cost. A wireless access point is deployed at each station for roadway application scenarios, real-time communication between the intelligent mobile device and the application server of the station where the wireless access point is located can be achieved when the intelligent mobile device moves to the coverage range of the wireless access point, the data transmission efficiency can be greatly improved, and the real-time performance of network communication is improved. Through two wireless radio frequency modules in a wireless node, different working frequency bands are adopted to carry out wireless communication with different wireless access points, so that different wireless access points can receive the same data at the same time, two channels can simultaneously work in a wireless network system, wireless channel resources are spatially multiplexed in a diversity
