Smart Lighting: The Cornerstone of a Truly Connected City

Connected street lighting extends beyond illumination, becoming a versatile platform for a spectrum of IoT applications.

In the era of the Internet of Things, a smart city is the ultimate convergence of ultra‑dense network connectivity and pervasive sensing—public safety, environmental monitoring, traffic flow, and more—all funneling data into open, integrated analytics engines. These insights continuously refine municipal operations and elevate residents’ quality of life.

As the United Nations highlights, the rapid urbanization of rural populations is a megatrend that will intensify city pressures. Meeting this demand requires a scalable, future‑proof foundation.

With limited budgets, city officials must prioritize investments that deliver immediate, measurable returns while creating pathways for long‑term innovation.

Many pilot projects end as isolated showcases, failing to foster a culture of sustained investment. Targeted spending—backed by a clear ROI—enables cities to build the IoT ecosystem they need and to generate new revenue streams that support further expansion.

Silver Spring Networks has positioned itself as a leader in this space, offering a comprehensive suite of smart utilities, traffic management, sustainability, and lighting solutions. Their platform is designed to be interoperable with existing power grids and utility fiber networks.

Connected lampposts do more than cut energy bills; they provide a robust foundation for an array of IoT services. Light poles are already deployed where people congregate—commercial districts, major thoroughfares, tourist hotspots, and civic venues—making them ideal sites for network infrastructure such as small cells, which are pivotal for smart city connectivity.

Scaling small‑cell deployments, however, faces two primary hurdles: securing power, backhaul, and site access, and negotiating placement agreements. Partnering with a city to deploy hundreds of integrated poles is far more efficient than negotiating with numerous incumbents.

Smart lighting providers are now embedding RF equipment directly into light poles. When a city replaces a few hundred streetlights, it can opt for a pre‑integrated solution that instantly boosts network density and creates a launchpad for additional IoT applications.

Silver Spring Networks claims that streetlights “create a foundation for long‑term value.” By reusing the same network for successive smart city applications, municipalities can reduce overall costs and accelerate deployment speeds. Their partner ecosystem and adherence to open standards grant cities flexibility and limitless extensibility.

In Chicago, the company supported a city‑wide project that will upgrade 250,000 light fixtures—an 85% replacement rate of municipally owned poles. The four‑year program will install LED lights that are projected to consume 50%–75% less energy than the existing system, marking one of the largest modernization efforts in U.S. history.

“Chicago’s lighting replacement initiative will be one of the largest modernization programs to date in the U.S., and we are proud to contribute,” said Mike Bell, President and CEO of Silver Spring Networks. “Mayor Rahm Emanuel’s commitment to leveraging state‑of‑the‑art IoT technology inspires us as we lay the groundwork for future smart city applications.”

Louis Maltezos, EVP of project stakeholder Ameresco, added that the new lighting will boost energy efficiency, enhance visibility, and improve safety—no more dark alleys. The poles will also integrate with the city’s 311 service portal and, in future iterations, could connect to 911 for rapid incident reporting.

AT&T, with a substantial presence in Atlanta through its connected‑car and smart‑home research centers, is collaborating with the city to roll out a smart‑city vision anchored by connected lighting. The pilot involves 1,000 wirelessly controlled LED lights in partnership with GE, city officials, and Georgia Power, targeting high‑traffic areas such as Buckhead Loop, Mercedes‑Benz Stadium, and the North Avenue Corridor. GE Current supplies the IoT sensor platform.

• Reduce traffic congestion and shorten commute times
• Improve police response times and lower crime rates
• Cut vehicle emissions and other pollutants

These lights serve as host platforms for sensors, cameras, and other IoT devices that collectively support traffic management, public safety, and environmental monitoring.

“Utilities are critical to building smarter cities across the region and the country,” said Mike Zeto, General Manager and Executive Director of AT&T Smart Cities. “Our smart‑city framework unites utilities, economic development organizations, research institutions, technology firms, developers, and municipalities to deliver tangible value and elevate citizen quality of life.”

AT&T’s 2016 framework partners with leaders such as Cisco, Deloitte, Ericsson, GE, IBM, Intel, and Qualcomm. The goal is to use “spotlight” cities to showcase the real impact of smart‑city applications across utilities, lighting, water systems, infrastructure, citizen engagement, transportation, and public safety.

Examples of how connected lighting sites can support these application sets include:

• Utility providers can remotely adjust power usage to reduce consumption.
• A lamp post with a small cell can connect sensors that help water utilities monitor flows and prevent flooding.
• Traffic cameras and sensors can feed data to a real‑time traffic management system.
• Public Wi‑Fi hotspots and kiosks can provide easy access to city services.
• Security cameras, gunshot detectors, and other IoT solutions can enhance public safety.

Investing in smart street lighting delivers quick ROI through lower energy costs while simultaneously establishing the infrastructure for a wide array of IoT initiatives that, together, transform a city into a fully realized smart city.
