Smart cities combine technology, government, and society to enable smart economies, mobility, a clean environment, and people living better. The Internet of Things is not a new concept. You have probably heard of smart homes and smart cars. Well, now there are smart cities. The smart home and the smart city are two major developments in IoT technology. Devices can communicate with one another, with people in homes and cities. In addition, they can even communicate with third parties from the outside. For example, a refrigerator automatically puts in a new order to a grocery store when important items like eggs, butter, or milk run low. However, there are other applications for this technology that take us beyond our homes and into the community at large. Therefore, let’s take a quick look toward the future.
