Meet San Diego's new IoT platform (and build your own)

This information provided by Smart Cities Council North America.

Data — and the ability to act on it in real-time — is the very bedrock of a smart city. But what’s an efficient way to build the data infrastructure you need? San Diego provides a great roadmap.

San Diego is using its street lights as a springboard. In two ways. As it’s equipping some of its lights with energy-efficient LEDs, it will also be adding sensors connecting to a powerful data network to help it make the public safer, improve traffic flow and more.

Second, it’s leaping over every other city. Under the plans, San Diego’s Internet of Things (IoT) network will become the world’s largest. Installation begins soon with the help of several Council Partners, including Lead Partner Current, Powered by GE.

At the Council, we often say that smart street lights are a great first smart cities project. Their energy efficiency provides a relatively quick, easy win and they’re a great launch pad for so much more. This is a project worth watching. (And emulating.) — Kevin Ebi


San Diego is on its way to turning its street lights into the world’s largest city IoT network, an effort that will not only help the city cut its power bill, but also provide wide-ranging benefits to commuters, first responders and others.

It begins with energy efficiency
San Diego’s IoT installation is prompted by an effort to slash the city’s power bill. Under the plan, the fixtures of 14,000 lights will be converted to efficient Evolve LED luminaries from Current.

This upgrade accounts for about a quarter of the city’s street lights and is forecast to cut energy costs by $2.4 million each year.

Why stop there?
Cities can stretch their LED retrofit investment by adding sensors and other technology while they’re working on the light pole. And that’s what San Diego is doing.

In the first phase, it’s installing 3,200 Current CityIQ sensor nodes during the LED upgrade. And that’s just the beginning. It could possibly double that amount before the year is over.

Benefits beyond energy
The new lighting fixtures reduce maintenance costs. Using Current’s LightGrid, managers will be able to optimize and check the maintenance of each light remotely through a single dashboard. But the addition of sensors carry the benefits well beyond lighting.

Parking sensors will track spaces and direct drivers to the nearest empty one, saving them time and frustration. Gunshot detectors will provide first responders with valuable information. And the city can build on that platform at any time.

Council Lead Partner AT&T will provide the secure, wireless data backbone using its LTE network. Council Associate Partner Intel is providing technology that can process some of the data at the street lights themselves.
