The world’s large cities will pose our greatest challenge—and greatest opportunity—in the next century. Today there are 21 “megacities” with more than 10 million people, and more than 1 million people move to cities every day. 70% of the world’s population expected to live in major cities by 2050. But today, cities waste an estimated $39 billion in water, gas and energy resources. As demands on resources and infrastructure grow, how will cities provide energy, water, transportation and other critical services for so many people?
Smart cities utilize IoT sensors, actuators, and a low-power, wide-area network (LPWAN) to connect components across the city. This connects every layer of a city, from the air to the street to underground. Smart cities can obtain data from everything that is connected and utilize it to improve efficiencies, reduce energy consumption and greenhouse gas emissions, lower maintenance costs and improve the quality of lives of citizens.
With an LPWAN city authorities can connect a countless number of battery-powered “things” into a single network, enabling data collection from parking sensors, environmental monitoring equipment, flood detection sensors or smart meters. The data is then fed to centralized intelligent systems which can make recommendations to optimize city service management.
City councils, often strapped for cash, can benefit massively from investing in smart city technologies. Both immediate and long-term cost savings can be realized, allowing increases to their budgets in other crucial areas of work (social welfare, green initiatives, etc.)
The Internet-of-Things (IoT) is being used in smart cities to make them safer, greener and more efficient. Wirelessly-connected sensors measure and monitor everything from air quality to parking stalls and water and gas meters.
Benefits of Smart Cities
A digital twin is a connection between the physical model and the corresponding virtual model or virtual counterpart. This connection is established by generating real time data using sensors.
A digital twin with enough data allows for unique insights into the operation of the physical model.
A digital twin offers a powerful way to monitor, control, and manage assets. Digital twins provide a comprehensive digital representation of real-world devices and systems, thus improving their state monitoring and enabling faster responses to external and internal events.
They are expected to become a keystone of every efficient IoT ecosystem.
