Wi-SUN Mesh Network spanning
15,000 luminaires
Major benefits
• Enables real-time remote management
• Reduces electrical energy usage
• Automatically generates maintenance service orders
• Provides a city-wide mesh network for
▸ Utilities
▸ Safety
▸ Parking
How is Wi-SUN helping?
• Future proof system (lasts for the next 30-40 years) that
can scale as the city converts old infrastructure to new
• Provides real time On/Off and Brightness control
• Provides Lux output readings and current consumption
• Provides safe, well illuminated environment for citizensThe network features 12 gateways, using Wi-SUN’s self-forming
and self-healing mesh functions to add devices to the network, as
well as UrbanControl’s software-based security offerings to comply
with the City’s stringent requirements.
Using Wi-SUN mesh pulls together three main
streams of thought: lighting for people,
sustainability and the future - City of London
