What Is 6G & When Is It Available?

Was the era of 5G over? Although it may seem surprising, talk has begun of a new future generation of networks in China, 6G. The future is on the way, and questions are already starting to arise about the advantages of this technology, when it will arrive, or simply what it consists of.

We will solve all these doubts around a new connection that will give a lot to talk about in the coming years in the telecommunications sector.

What is 6G?

The sixth generation of mobile connectivity, or as it is popularly known, 6G, is the successor to 5G with higher speed and lower reaction time. Although it is already echoing what 6G will be and with 5G still in force, a transition period is expected. Specifically, it will be in 2024 when 5G+ or advanced 5G will burst in with speeds reaching 10 Gbps.

Under the same objective as 5G, 6G will try to reduce connection latency and raise transmission speeds to levels never seen before. The fields that benefit the most from 6G are extended reality, artificial intelligence, energy efficiency, and holographic communications.

What benefits does 6G have?

In an increasingly connected world like today’s, future technology must consider this fact and improve the combination of different realities. In this regard, the emergence of this technology will speed up this connection and combine it with new trends such as virtual, augmented, or mixed reality.

Even considering the machine learning that AI implies, with 6G, it will be about networks being distributed, optimized, and managed autonomously.

This technology’s efficiency is also one of its most significant advantages. And is that saving energy supposes an opportunity for optimization of the resources and a greater capacity of support that allows a simultaneous connection between different devices.

5G vs. 6G

5G vs 6G

5G is relatively recent, so the appearance of 6G has impacted the market. And when 5G begins to be promoted at a commercial level, the research and development projects of the new technology that will be imposed begin.

Being so close in time, there are hardly any differences between one generation and another, but the reality is that they are different. Some of the differences between 5G and 6G are the following:

  • 5G and 6G use both parts of the spectrum. On the one hand, 5G covers broadband frequencies below 6 GHz and 24.25 GHz above. Both will be known as the low and high bands. Instead, 6G will move between 95 GHz and 3 THz (terahertz). Thanks to these wavelengths, the speed of 6G will exceed 5G by 1,000 times.
  • The Internet of Things ( IoT ) is achieved through 5G. Now, the mission of 6G will be to improve and accelerate 5G for this technology.
  • 6G will be used for particular purposes. In other words, 5G does not replace 6G; this new technology will be applied for business, industrial, or even military purposes. The most striking use of 6G technology is its use in automated drones for military purposes.
  • The infrastructures required by 5G posed difficulties that affected its speed. With 6G, they will make the most of it, improving connectivity both on land, at sea, or, most surprisingly, in space.
  • The latency time (information packet transmitted on a frequency) in 5G networks is 5ms. With 6G, latency will be reduced from 1 millisecond to 1 microsecond. In this way, massive data transmission is achieved since latency is reduced five times that of the 5G network.

Was 6G necessary?

Currently, 5G has already covered people’s needs in terms of handling large volumes of unstructured data online. However, related factors such as 6G technology, such as minimum latency or maximum communication reliability, and other external factors, such as M2M communication linked to the Internet of Things, favor the birth of this new generation.

The forecasts regarding this new technology are to connect ten times more devices per square kilometer. The power that the current 5G cannot achieve. This aspect is fundamental in responding to the automation flooding all sectors.

When will 6G?

The commercial launch of this new generation is scheduled for the year 2030. Although there are still years left for it to take place, one must be aware that the current 5G still needs to be implemented. For this reason, there are areas where they can go from 4G to 6G without going through a transition period.

This new technology is not a theoretical concept, but satellites with 6G capacity from China have already been put into orbit to test their effectiveness. After this launch, it was followed by other telecommunications giants such as Huawei or Samsung that have underway research projects for this technology.
