Alphabet’s urban IoT subsidiary Sidewalk Labs has announced a new project which could see the company build a ‘digital district’, and even an entire U.S. city, to test its innovative, smart solutions before rolling them out at a wider scale. According to a post on The Information, Sidewalk Labs is partnering up with over 100 leading urban planners, technologists and consultants to work on a proposal for counties and U.S. states to bid to host the first of the digital communities.
