Cities all over the world are getting smarter. And this smart city technology has everything to do with the ever-burgeoning Internet of Things — the vast network on which numerous linked devices share data that’s analyzed and then acted upon to optimize conditions in a variety of sectors.

IoT in Smart City Technology

Smart city technology uses IoT’s hyper-connectivity to make cities safer, greener and more efficient. IoT devices are being deployed throughout cities to measure and monitor everything from air quality to traffic and crime patterns.

From traffic lights and parking to environmental sensors and waste management, IoT helps urban areas operate more smoothly, sustainably and efficiently, which enhances the quality of life for residents and saves money in the process. As is the case any time large amounts of personal and public data fly back and forth, there are security concerns, but they seem to have had little impact on growth. According to one report, cities are expected to invest about $41 trillion through 2035 “to upgrade their infrastructure to benefit from the IoT.” The cost savings of doing so could be huge, as well.
