About this Research Topic
In Europe, cities account for 75% of the population and consume 80% of energy. Since they were built on infrastructure designed for a smaller and less active population, the influx of people can create new opportunities but also pose major economic, environmental and social challenges. As a result, the need for innovative solutions to solve arising challenges in cities is growing rapidly. Recently, breakthroughs in next generation wireless technologies such as 5G and Wi-Fi 6 are evident with the aim of benefiting society. Wi-Fi technologies are designed to provide devices with exceptional signal coverage and high-speed transmission for indoor activities. In comparison, cellular service, such as 5G, is designed to provide seamless data connectivity for outdoor networks. Next generation wireless communication techniques together with Internet of Things (IoT) and Artificial Intelligence (AI) will create a new paradigm to enable novel application scenarios and services to be deployed in future intelligent transportation and smart cities by effectively sharing information among different entities in a fast, flexible and reliable manner.
5G technology is on the way to revolutionize how we use and access the internet in our daily lives. It aims to hugely expand the possibilities and capabilities of current mobile networks with an ambition to support ubiquitous network connections with billions of IoT devices, and one hundred times increase in the individual end-user data rate experience with extremely low latency and response time in data communication. On the other hand, the new Wi-Fi 6 standard, which is known as the next generation of Wi-Fi, is being developed not only to provide network speed at least four times faster than Wi-Fi 5, but also with significant improvement in efficiency and capacity to cope with the increasing number of devices connected to the internet for most indoor network scenarios.
Both 5G and Wi-Fi 6 have a vision to provide better performance to customers and mobile users. However, there are fundamental differences in both technologies and how they can be applied to various use cases. For instance, 5G usually comes with higher costs in use of infrastructure equipment, licensed spectrum, when compared to Wi-Fi technologies. On the other hand, Wi-Fi networks usually have a short range that is limited by its frequency, transmission power, antenna type, among others, and thus it cannot provide coverage to wide areas when compared to 5G. In addition, Wi-Fi 6 can also play an important role in OTA software updates. The key difference is that the transaction/connectivity fees are much lower compared to 5G. At this stage, it is important to realize that both technologies need to co-exist and complement each other to support different use cases for the advancement of smart cities.
