Smart Street Lighting System

SmartELI is a modular street lighting control system that makes street luminaires more energy efficient and cuts maintenance cost. SmartELI controls the complete street light management infrastructure in Tallinn, Estonia.

The smart street lighting system is designed to be future-proof. It uses open IP-based wireless communication enabling standalone street lighting infrastructures to become hubs for Internet of Things (IoT) and Cloud-based services.

The SmartELI control system consists of three components:

  • Wireless Luminaire Controller
  • Control Cabinet Gateway
  • Control Server and SmartELI Software

Each luminaire has an IP address and can be controlled individually over the 6loWPAN (IPv6 over Low power Wireless Personal Area) mesh network. The control cabinet gateway connects the luminaires to the SmartELI software over the mobile network. The software enables real-time street light management and grid monitoring services and access to any IP-based sensor or device in the network.

Municipalities have the option to gradually invest in modern technology. The modular SmartELI street light- and line-based systems work seamlessly together. This enables to either install a complete luminaire-based system or start by managing entire streets or groups of streets.

The street lighting system is used to gather valuable data about the urban environment on a demo street in Tallinn. See it in real-time at the Eliko smart city website.
