A smart city is a modern city that uses technology to improve its residents’ lives. This includes using electronic methods and sensors to collect data from people and infrastructure, which is then used to improve efficiency, sustainability, and quality of life. Smart cities also use digital technologies to make government services more modern and accessible and to promote economic development.
Smart cities use a range of technologies, including the Internet of Things (IoT), mobile solutions, big data, artificial intelligence (AI), and blockchain. These technologies help to make better decisions and improve the quality of life. By using more comprehensive, real-time data, agencies can watch events as they happen, understand how demand patterns are changing, and respond with faster and lower-cost solutions.
There are three layers that work together to make a smart city: a physical layer of infrastructure, a digital layer of technology, and a data layer that connects both. This can be seen in shopping centers, parks, and stadiums, where cameras, floors, waste management, and escalators can all be managed with IoT devices and a central management room.
Internet of Things (IoT) and Cyber-Physical Systems are also used in sectors such as transportation, energy, manufacturing, and healthcare to improve services, promote economic growth, and enhance the quality of life.
However, there are concerns about data privacy and social exclusion in smart cities. There is a risk that urban areas with poor web connectivity could be left out of the smart-cities trend. But technologies and platforms are being developed and improved to address these concerns, such as blockchain platforms that provide more secure environments and improved network gateways that work with low voltage to address network connectivity issues.
Another technological platform used in smart cities is the digital twin. This is a digital representation of a physical product, system, or process that serves as a digital counterpart of it for practical purposes. It can be used to simulate, integrate, test, monitor, and maintain physical infrastructure. Digital Twin uses gaming platforms like Unreal Engine or Unity to create an exact replica of the physical infrastructure and connect data from IoT devices to management centers.
In summary, a smart city is a modern city that uses technology to make life better for its residents. It uses a range of technologies, including IoT, mobile solutions, big data, AI, and blockchain, to make better decisions and improve the quality of life. While there are concerns about data privacy and social exclusion, technologies and platforms are being developed and improved to address these concerns.
