Smart cities are urban areas that use 5G technology and Internet of Things (IoT) devices to connect infrastructures, organisations, and urban activities together – as well as with its citizens. Thanks to the characteristics of 5G technology, devices and sensors of a smart city will be interconnected and able to both collect and exchange critical information in real-time. This is the case because of its ability to support many connected devices with low latency. This will help improve urban planning and reduce public spending through the more efficient management of resources. Additionally, it will contribute towards creating a safer and more comfortable city that is respectful to the environment. Smart cities can also improve the relationship between citizens and their local government, with faster, improved channels of communication and the development of an e-Government.
Smart water meters are an example of such devices. They can be used to gather information to better understand water problems, such as water leaks. City officials can use this data from smart meters to target a water conservation campaign in areas where water is being wasted. Another example is the interconnection of traffic sensors and smart vehicles, which can provide information to authorities about traffic congestion and pollution. Smart cities may also be able to improve the efficiency of public transport and expand routes in particular zones of the city.
