ubiquitous wireless communication device and method using visible light Solar LED street light network

摘要

The present invention is a device to identify the traffic using the existing ITS server is visible, visible light street light, consists of a one-way network, leading to the vehicle, only when the information request signal from the vehicle towards the ITS server communication is occurring, improving the problem that the easy break off communication quality of the signal by the structural condition of a road or weather conditions to the first car and street lights, connect with each other to form a central control server networks ubiquitous sensor network communication module so visible visible after vehicle wireless communications, Solar LED Street Light, by being configured, sink unit, central control server, visible vehicle communication module, solar LED street lights, sink node unit, the central control server can be a two-way data communication, the communication may be as little power, it is possible to disperse the shot noise and thermal noise due to external pressure via a ubiquitous sensor network mans , fast, accurate there is provided a radio communication apparatus and method ubiquitous visible light using a visible-light wireless communication network that can be a solar LED street light.
