Smart city is something of a broad term that generally refers to using wired or wireless sensors to gather data which is feed into a compute infrastructure, analyzed, then used to initiate an outcome that makes the operation of a municipality more efficient.
Drilling down to specific use cases, they run the gamut from smart lighting and traffic management to improved access to city services and air or water quality monitoring. But, regardless of the particular application or desired outcome, underlying a smart city is (ideally) easy access to high capacity fiber that can support current and future needs.
