IoT and smart cities effectively address the growing resource demands of many citizens who live, work, commute and interact with one another. IoT and smart city initiatives, for instance, are being used to enhance traffic control, energy usage, public safety and healthcare.


Every smart city in the world is supported technologically by IoT, which gives them the information, connectivity and tools necessary to enhance urban services, maximize resources and cut costs. IoT can offer real-time information and insights into a city’s infrastructure and operations through the coordination between multiple devices, systems and people.


The use of IoT devices and networks forms the basis of smart cities. These technologies when paired with software solutions, user interfaces and communication networks enable the performance and effectiveness of smart cities.


To build a genuinely smart city that can enhance the quality of life, the ultimate goal is to have IoT technologies integrated with data effortlessly flowing between devices. Some technologies that are included in building a smart city are:

  • Radio-Frequency Identification (RFID)

RFID uses radio frequencies to tag devices to send data and for tracking and identifying persons and objects. Tracking the whereabouts and motion of vehicles, equipment and even people in a smart city can produce significant data that can be utilized to improve the performance of transportation systems, garbage collection routes and parking availability.


RFID has applications in safety and security measures by providing real-time tracking of people and vehicles. Smart cities are raising the bar when it comes to living standards by integrating intuitive and intelligent elements into a single and distinctive architecture.


RFID technology in a smart city helps in parking management, preventing crimes and tracking victims. It can be extremely beneficial when used appropriately in the healthcare industry, wherein RFID readers and sensors are used in digital bands to make wristwatches.


These watches can help in scheduling appointments, exercise timings, medications and meals. Similarly, they are extremely helpful in tracking victims of disasters such as hurricanes, earthquakes and cyclones.


RFID tags attached to certain objects use unique identifying numbers to store information, and offer another application. RFID readers detect this data to find the tags and present it to emergency staff, crisis management teams or rescue crews.


  • Near-Field Communication (NFC)

NFC is a set of techniques that allow smartphones and devices like credit card readers, to establish radio contact when held within a limited distance (typically a few inches or centimeters). For two-way short-range communication in smart cities, such as contactless payments, access control and electronic ticketing, this technique is extremely helpful.


  • Low-Power Wide-Area (LPWA)

For IoT applications that call for low-power, low-cost and low-bandwidth connectivity, licensed spectrum’s LPWA technology is the best option. These technologies also profit from a battery life of about 10 years. Applications like building automation and industrial automation use LPWA networks in a smart city.


  • Wireless Telecommunications

Mobile phones and data terminals have been the main users of the cellular wireless telecommunications protocols 3G, 4G Long-Term Evolution (LTE) and 5G. As compared to earlier wireless generations, 5G significantly improves speed, density (number of connected devices), capacity (network throughput) and energy efficiency.


5G’s higher density allows it to accommodate 10 times more connected devices per square kilometer of the network. This feature is especially important given the rapid growth of IoT. In smart cities, 5G and IoT are crucial for applications like traffic control, emergency response and self-driving cars.


  • Wireless Sensor Network (WSN)

WSN is a network made up of numerous tiny, low-power gadgets called sensor nodes that are not connected by wires. To monitor and gather data, these nodes are deployed in a range of situations and are specifically equipped with sensors, microcontrollers and wireless communication capabilities.


WSN has a wide range of applications in smart cities, including tracking temperature, humidity, air quality, pureness of drinking water, critical military missions, road congestion avoidance and forest fires.


  • DASH7

DASH7 is a long-range, low-power wireless communication standard that is excellent for IoT gadgets like active RFID tags and sensor networks. Generally, applications requiring only a small amount of bandwidth, such as text messages, sensor readings, asset tracking or coordinates for location-based advertising, use this technique.


Role of IoT in Smart Cities

Smart urban mobility, urban sustainability and smart buildings and environments are major avenues for IoT applications in smart cities.


  • One of the biggest problems facing city administrations is traffic congestion. By making numerous real-time data on vehicular movement available, IoT is significantly reducing traffic congestion. Monitoring and analysis of traffic flows are done using smart traffic management technology.Based on the time of day or congestion schedules, these systems optimize traffic signals and aid in preventing roadways from being overly congested.


  • To assist drivers in finding available parking spaces without constantly driving around packed city blocks or parking lots, smart parking applications use cameras and sensors. Parking spot sensors send information to a server, which then distributes it to drivers via display boards or applications on mobile phones.


  • Based on the movement of vehicles and pedestrians, smart lighting adjusts the streetlight intensity. This reduces light pollution and results in significant energy savings. Additionally, installing sensors in these street lights helps lower maintenance expenses.


  • Utility firms can efficiently regulate the flow of energy with the help of smart meters. They are IoT devices that are affixed to buildings and connected to a smart energy infrastructure. Smart meters give users the ability to monitor their energy use, increase energy usage awareness and open up the possibility of cost savings.


  • Sensors are used to monitor the amount of waste stored in trash cans and recycling bins and determine the most effective pick-up routes for waste management firms or public services. Smart waste management can help in increasing efficiency and cutting costs.
