Wireless Radio Street Lighting Control in Dhaka, Bangladesh

A modern wireless street lighting control system was deployed in Dhaka, Bangladesh, covering over 3 500 LED luminaires. The solution uses LiWAVE, a proprietary wireless communication protocol developed by DITRA, which enables reliable two-way communication between each luminaire and the central management system. This setup allows operators to manage lighting scenarios, monitor performance, and optimize operation remotely — without relying on cables or SIM cards.

What Was Implemented
  

Each luminaire was equipped with an individual radio node that connects wirelessly to a nearby LiWAVE Base Station. 

This architecture allows:

• Individual control of each luminaire

• Creation of custom groups for area-based lighting control

• Scenario-based switching depending on time, traffic, or event

• Remote brightness adjustment and status monitoring

LiWAVE ensures stable radio communication in open urban environments, making it especially effective for cities with moderate building density, regional roads, and open areas where traditional wired or cellular infrastructure is limited.

Why LiWAVE: Key Advantages of the Wireless Protocol

LiWAVE, developed by DITRA, is a wireless communication protocol tailored specifically for intelligent outdoor lighting. It combines flexibility, scalability, and efficiency in one robust system:

• Dual-Level Control

  Lighting can be managed both individually and in groups, giving cities operational flexibility. Grouping luminaires also helps reduce costs — for instance, a single motion sensor can trigger a group of lights, avoiding the need for sensor installation on every pole.

   

• Sensor-Ready

  The system supports integration with motion sensors, environmental detectors, and other smart modules, allowing the network to adapt dynamically to real-world conditions.

   

• No SIM Cards or Cabling

  LiWAVE uses radio frequency, eliminating the need for cellular networks or trenching — reducing installation time and long-term costs.

   

• Scalable & Future-Proof

  The network can be expanded at any time by adding more luminaires, sensors, or new control features — without altering the core infrastructure.

   

Results & Benefits

• Full individual control of 3 500+ luminaires via radio communication

• Significant energy savings through tailored lighting scenarios

• Reduced operational and maintenance costs

• Improved lighting quality across various city zones

• Flexible architecture ready for future smart city integrations
