Currently in some countries 5G mobile connectivity technology is being deployed, especially in nations with higher development rates, however, there are already indications of the development of the next mobile connectivity: 6G.
3G, 4G, 5G and now 6G What is all this?
Over the years there have been several generations of wireless connections, which began in the eighties with the first mobile phones, such as the Motorola Dynatec, developed in 1983 being the first phone capable of making sustainable mobile calls with one hand.
The first mobile technology developed was the 1G that was an analog system, with the advances in the 90’s came the second generation of wireless connections called 2G that already had digital features and encryption in the calls, among the novelties of the 2G network network was a greater capacity to send data to fax and modem devices also appearing the Short Message Service better known by its acronym SMS that allowed you to send texts to other phones,
Then came 3G technology, which began with the Internet revolution, allowing the exchange of emails and downloading data from the web, in addition to maintaining the functions of calls and messages. Unlike its predecessors, it has greater security, highlighting its function, which is able to offer internet connection service through a USB modem without the need for a cell phone, so this service became extremely popular in the last stage of the year 2000.
Although in some countries 1G and 2G networks are practically obsolete, in some others 3G technology is still used to offer low-speed calling, messaging and internet service.
After 3G, the International Telecommunication Union ruled the specifications that the next generation would have to have, which was called 4G and within the dozens of requirements that are needed for this denomination to be met, highlighted the fact that the maximum speeds of data transmission must be between 100 megabits per second for cases of high mobility and up to 1 gigabit per second for mobility casualty.
The first company to reach the standards was the NTT DoCoMo in Japan that launched 4G services based on LTE technology in December 2010 in some cities of the Asian country. 4G services had good implementation and acceptance, thus taking the next step: 5G.
5G, is in the process of expansion in the world, according to estimates of the GSM Association, one of the main in terms of mobile connectivity, by 2025 it is expected that there will be 1.7 billion people using this service, which has as its main advantage over the last generation to support a much larger bandwidth, exceeding 10 gigabits per second, 10 times more powerful than the transmission speeds of 4G technology.
Through 5G it is expected that there will be a revolution in the field of technology, due to its high speed rates, different applications of the mobile network such as the Internet of Things can be developed.
One of the disadvantages is that, although you have higher speed, more cells are required for its connectivity, since it has a shorter range than 4G. The first commercial-use 5G networks were launched in 2019 and began expanding worldwide from 2020, so it is expected to reach its peak of users in 2025.
Everything indicates that the next generation should already be on its way, 6G technology is already beginning to form.
What will 6G technology look like?
Although it is too early to talk about a standard in terms of 6G technologies, there are already some forecasts regarding what can be done with this technology and when it will arrive, it is expected that its commercialization will begin in 2030, with «real» uses of this network between 2026 and 2028.
The implementation of 6G Networks will improve the use of extended reality, holographic communications, greater artificial, automated and interconnected intelligence, as well as greater energy efficiency.
There is even a position on Samsung in this regard, in which it estimates, download and upload speeds can multiply to reach peaks of a thousand Gbps and recommends using bands from below 1Ghz and up to 300 GHz depending on whether it is low, medium or high.
This is also endorsed by Oppo, who assures in a first technical report on 6G that this technology will be able to revolutionize Artificial Intelligence and its interaction and application.
Mainly, it is expected that up to 1 terabit per second of speed and a latency of 0.1 ms can be reached, which would be a big step in mobile network technology.
Since 2018, China through the Ministry of Industry and Information Technology confirmed that it was investigating 6G, although most technology companies and governments such as Finland, South Korea and even China, estimate that most services could be launched in 2030.
Just in February of this year, researchers at Tsinghua University in Beijing managed to broadcast more than 10,000 high-definition videos simultaneously in a remote location that represented a sending of 1TB of data in just one second.
While we are about to enter the phase where 5G begins to be applied around the world and reap the benefits of this «new» type of mobile connection, the world does not stop and the technology is expected to continue with the giant steps of growth in mobile connectivity.
