inteliLIGHT® controllers are mounted inside or outside the street lighting fixtures, while the communication devices are placed inside the power supply cabinets. inteliLIGHT® communicates using PLC (Power Line Communication) or RF communication between the lamps and the power supply cabinets and using any IP-based communication solution available between the cabinets and the management software. The built-in advanced signal repeating mechanisms make it possible to communicate securely even over the largest street lighting networks.
