Powerline Street Lighting Control in Lagos, Nigeria
3 500 LED luminaires managed via frequency-modulated LiteLINE protocol using existing power line infrastructure.
A large-scale street lighting control project was carried out in Lagos, Nigeria, covering over 3 500 luminaires. The solution is based on DITRA’s LiteLINE protocol, which uses existing power lines to transmit control commands and data — eliminating the need for additional communication infrastructure.
What Was Implemented
To achieve full system coverage, controllers were installed both in lighting poles and control cabinets:
Pole-mounted LiteLINE Nodes provide individual control, real-time status monitoring, and energy tracking for each luminaire
Cabinet controllers DITRA LiteLINE manage groups of luminaires and offer centralized control over entire lighting zones
Communication is carried out via the LiteLINE protocol, which uses frequency modulation to reliably transmit data over the same cables used for power supply. This significantly reduces deployment costs and simplifies installation — especially in dense or hard-to-access urban areas.
Why LiteLINE: Advantages of the Protocol
LiteLINE, developed by DITRA, is a lightweight and efficient powerline communication protocol designed specifically for street lighting systems.
No additional communication cables required — data and power share the same line
Stable performance thanks to robust frequency modulation
Supports individual and group control for flexibility in urban planning
Ideal for large-scale deployment with minimal infrastructure changes
Scalable and upgradeable for future smart features like sensors or dimming
Results & Benefits
Individual and centralized control of 3 500+ luminaires
Energy savings through intelligent scheduling and monitoring
Lower installation costs due to reuse of power line infrastructure
Improved lighting reliability and real-time fault detection
Smart city readiness with a scalable, non-invasive architecture
