Already known as the "most connected" country in the world, South Korea has set a new record by becoming the first country in the world to deploy 5G technology on its territory since April 3.But like any new system, 5G obviously raises a few questions. But like any new system, 5G obviously raises some questions, and many professionals are wondering whether it brings real improvements in terms of usage and digital speed.
Introducing 5G5G follows 4G and is the next generation of standards and norms for mobile networks. It is likely to provide very high data rates in the mobile telecommunications field, in the order of several Gb/s (i.e. data transmission 100 times faster than 4G), and with the marketing of connected objects and smartphones that are increasingly powerful and sophisticated, such rates would be welcome.
They would not only facilitate the development of interactive games, datamining, interoperability and integration of communicating systems, cloud computing, ... but would also allow operators to meet user needs (low latency, connection speed to easily create an ecommerce site, ...). Just as 4G was developed to improve the performance of 3G, 5G was developed to increase the performance of 3G. While it is currently only available in South Korea, 5G will be deployed in other countries (United States, Japan, China, ...) in the coming months.
As a reminder, here are the main improvements made by the previous generations of mobile networks:-1G: sending/receiving calls;-2G: sending messages in text format;-3G: sending messages with the possibility of attaching images;-4G: development of the mobile Internet;-5G: connection of all the elements that were not connected until now.
What to expect with 5G?While 4G has played a major role in the development of digital economies, 5G should offer new services and meet new requirements (the modes of transport of the future, for example). It should be pointed out that it has not been deployed to increase subscriber throughput significantly, but rather to increase traffic and solve network saturation problems, regardless of the number of people online. It is in the industrial sector that the impact of 5G would be felt most strongly. It should notably allow the integration of virtual or augmented reality, the monitoring of the different stages of the product assembly line, the development of telemedicine, .
Because of the type and the large amount of data it would allow to transfer, 5G would unfortunately present some security flaws. We can only hope that solutions will be found quickly.
