Thousands of new “smart” streetlights to be rolled out across the city of San Diego will be connected to a city-wide network, allowing officials to adjust their brightness and detect outages from afar. But in addition to giving off light, they will also be pulling in information about what’s going on around them. Last month, San Diego announced it would install a 3,200-node sensor platform in soon-to-be-upgraded streetlights across the city this summer, in what officials say will be the world’s largest smart-city Internet of Things (IoT) network. The $30 million program is part of a deal with General Electric’s Current unit, as the city upgrades 14,000 streetlights to Current’s energy-saving Evolve LED systems.
