LoRa-based City Streetlight Control Solution

0ab37426e0387c98dd6e7e2b6385384bThis solution adopts a three-layer architecture: System Platform – Gateway – streetlight controller. The gateway communicates with the system platform via the cellular network (4G/5G), and the streetlight controller communicates with the gateway via LoRaWAN or LoRaMESH. LoRaWAN is widely used in city streetlight scenarios, where it adopts the LoRaWAN V1.0.4 and V1.1 protocol at the link layer and connects to the LNS service first before accessing the system platform at the network layer. LoRaMESH is mainly used in streetlight scenarios of towns or parks, where it adopts a proprietary protocol at the link layer and directly accesses the system platform at the network layer.

LiCON products for this solution:

  • SLC1 series plug-in streetlight node，with NEMA or Zhaga standard interface, directly plugged on the top of the luminaire.
  • SLG6 series gateway, hoop-mounted on the middle of the streetlight pole. Its site selection shall be evaluated, simulated and tested.
  • LiLAMP CMS, monitoring and control platform for city lighting, supports both on-premises deployment as a control center and cloud deployment as a cloud platform.

Solution

Solar Streetlight Remote Control Solution

Compared with the uniform and continuous deployment of city streetlights, solar streetlights are mostly distributed in sections and deployed non-continuously. Therefore, we recommend a solar streetlight control system based on cellular communication, which solves the difficulty of offline management of solar streetlights. As the key communication unit of the system, the DTU (Data Transmission Unit) connects with the solar streetlight controller southbound via RS-485 or TTL interface, and connects directly to the system platform northbound via 4G Cat.1 or NB-IoT cellular network to realize remote monitoring of solar streetlights. When connected to a microwave radar, the lights can operate in response to pedestrians or vehicles.

Cellular-based City Streetlight Control Solution

This solution adopts a two-layer architecture: System Platform – streetlight controller, achieving gateway-free or concentrator-free operation. The streetlight controllers communicate with the system platform in real time via LTE Cat.1 or NB-IoT. LTE Cat.1 streetlight communication technology was globally pioneered by LiCON and has become a China national standard with the widest application. With the wide coverage and large bandwidth of LTE networks, it achieves an online rate of over 98% for real-time inspection. NB-IoT streetlight communication technology is widely used in Europe.
