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.
