  • Product name: 3rd generation of RSU
  • 产品名称:
  • Code:

  Road side unit (RSU) is the key equipment for the ETC lane system. Based on the two generation RSU, Wanji develops the third generation RSU which integrates three major techniques. They are the mature phased array technology, DBF technology and LiDAR technology.

  First of all, the product can not only make phased array to extend the transaction coverage, but also avoids the traffic problem of adjacent interference by using the digital beam-forming technology. Therefore, the product guarantees the transaction will be successful. Secondly, the product adopts LIDAR technology to classify the vehicle types in real-time Therefore, the product can rule out several traffic problems including following vehicle, ETC evasions and cheats.
