How is 5G advancing the urban infrastructure and building Smart cities?

The introduction of 5G technology, which is expected to transform the technological landscape, is predicted to have a substantial influence on the Internet of Things (IoT) and smart cities. Thanks to its ability to offer faster speeds, lower latency, and more consistent connections, 5G has the potential to allow new use cases and overcome the limitations of current networks. But before that, what is a smart city?

A smart city as described by the European Commission is "a location where traditional networks and services are made more efficient through the use of digital and telecommunication technologies for the benefit of its residents and business." The Internet of Things (IoT) is used by smart cities to gather real-time data, better understand how demand patterns are changing, and respond with quicker and less expensive solutions. To become a smart city, a city must have the diffusion and accessibility of new technologies, which will help the city achieve a high degree of sustainable urban growth and improve the quality of life for its residents.

According to IoT trends, there will be 75 billion linked devices on the planet by 2025. The IoT standard must provide advanced features, such as longer battery life and a wider coverage area, to enable the expansion of new use cases, while also providing enough capacity and network efficiency to connect millions of devices. This will help realize the vision of having millions of connected devices. The current 4G network was created largely to improve mobile data services, however it still has several drawbacks. These restrictions include inadequate simultaneous connection support, high power consumption, and an excessively high cost per bit. By addressing and resolving these problems, 5G is anticipated to unleash the IoT's potential and serve as the driving force behind the smart city.

A lot of 5G technology's capabilities will improve digital experiences and smart cities. Additionally to faster upload and download speeds, it guarantees very low latency periods and simultaneous connection of several devices. Compressing the time between transmitting and receiving the signal results in less latency. Data will be sent close to in real time thanks to 5G, which reduces the range to at least under 10 milliseconds (about half of what the most sophisticated 4G could achieve) and, in best instances, under 1 millisecond latency. Furthermore, even with thousands of linked devices, speed and latency on new networks don't degrade. Therefore, 5G provides a higher device density.

Low latency and high density will fundamentally alter our cities. Today, connections might occasionally deteriorate in congested tourist areas like stadiums. This will no longer be the case with 5G, as each square kilometer will be capable of supporting a significant number (up to one million) of simultaneous connections. This implies that many additional devices, objects, and sensors will be able to collect information and communicate with one another in addition to personal devices like smartphones, tablets, smart speakers, and PCs. Extreme simplicity, low power consumption to provide extended operating times and widespread coverage for difficult-to-reach places, and greater connection density will all be prioritized so that networks can support the enormous number of devices deployed for IoT applications. The Internet of Things will thus be able to realize its potential not just in the home environment but also in industrial facilities, public buildings, and on the streets as a result of 5G thereby removing one of the roadblocks to its development.

In the end, 5G transforms the development of smart cities from a theoretical to a practical endeavor and paves the way for the creation and introduction of novel applications ranging from street lighting, intelligent parking, crowd management, and emergency response to the observation of air quality, energy use, and traffic patterns. A number of important quality of life indices have improved dramatically because to the smart city's utilization of data, technology, and digital solutions. As a result, there is an enormous potential for savings and improvements in traffic and commuting times, emergency response times, healthcare expenditures, water use, non-recyclable trash, and hazardous pollutants.For businesses that offer services and software to manage intricate IoT networks and transform data into insightful knowledge, this opens up new revenue prospects. Several national, regional, and European programs help to solve urban-related issues.
