Smart city

What is a smart city?

Due to the Internet of Things (IoT) technologies, Local governments are using cellular and Low Power Wide Area Network (LPWAN) broadband innovations to link residents and visitors. The main purpose is to enhance communication, performance, comfort, and standard of living. A smart city is a platform for developing, deploying, and promoting sustainable development activities to resolve growing urbanization challenges. It is based on information and communication technologies (ICT). The cloud is a major part of this ICT system. Real-time data is received, analysed, and managed by cloud-based IoT applications to assist municipalities, businesses, and residents to make different decisions that enhance the quality of life. Citizens interact with smart city environments in a variety of ways, using their smartphones as well as they can connect vehicles and homes items. IoT is playing a vital role in garbage collection, traffic improvement, and even improve air quality.

 In general term, a smart city, is one that uses technology and provides infrastructure and solve problems. A smart city enhances transit and connectivity, strengthens social services, encourages prosperity, and empowers its people. A smart city’s key objectives are to enhance economic, and social performance in the city.

How smart city technology works?

Edge computing is also benign used in IoT devices. LTE Cat M, NB-IoT, Lora, Bluetooth, and a few other technologies are being used in connected cities. The introduction of 5G technologies is required to be a landmark moment for smart city technology, it will make the new implementations with high-speed delivery.  Traditional city features, such as streetlights, are being turned into next-generation lighting control systems with enhanced capabilities. Thanks to secure wireless networking and IoT technology to incorporating solar power and linking to a cloud-based centralized power system that links to another ecosystem.

• Integrated high-power LEDs alert drivers about traffic congestion, extreme weather alerts, and environmental hazards such as fires.

• Lighting systems can also identify open parking spaces.

Features of smart cities

• Smart utility meters

The smart meter is a common IoT system between utility companies. These devices link to a smart energy grid allowing utility providers to better control of energy flow. Users can monitor their energy consumption with smart meters, which has a major financial effect.

• Smart transportation system

Intelligent Transportation Systems (ITS) are sophisticated software that provides the new solutions related to various modes of urban transportation control, allowing different users to be properly informed and allow more organized, and better use of transport systems. Drivers are attracted to smart transport because of voice search and location data features.

• Smart Sensors for Air Quality

Modern cities are now using IoT sensors to collect a range of air quality data, containing concentrations of particulate matter, carbon dioxide, ozone, nitrogen dioxide, and more. This information is being used to make the city cleaner and much more manageable.

• Smart street lighting system

A smart street light system is made up of a group of streetlights that can interact with one another and send lighting data to a central concentrator. The concentrator collects and sends relevant information to a secure server, which records it and displays it in a web-browser dashboard.

Examples of smart cities

Cities all over the world are at various stages of designing and adopting smart technology. There are, however, a few that are ahead of the competition, opening the way for truly smart cities. There are some of them:

• Barcelona
• Columbus
• Dubai
• Hong Kong
• Kansas City
• London
• Melbourne
• New York City
• San Diego
• Singapore
• Reykjavík (Air Quality)
