The 5G has just arrived and still has a lot, a lot, a lot of road ahead. If we look at the Spanish case, the 5G NSA is only available in a handful of cities in the hands of Vodafone and does not have all the benefits of 5G SA, such as a higher upload speed or a latency of just a few milliseconds. This can be extrapolated to almost all countries, since a major change in infrastructure, ergo a great investment.

However, and although 5G is still in diapers, Huawei already works in the 6G network. This has been confirmed by its CEO, Ren Zhengfei, in an interview with the CNBC. "We work in parallel in 5G and 6G, so we started with 6G a long time ago," says the CEO, who does not hesitate to recognize that he is at an early stage and that there is "a long way to go."

New 10-year network view

5G

According to Zhengfei, the 6G network is "ten years away", so we have to wait a lot. Mainly, because launching a new generation network is not as simple as increasing speed and improving latency, but rather a series of standards must be approved, the technologies to be used and a definition given, something that, for the moment, It is far. Experts put 2030 as the estimated date.

That does not mean that some steps have not been taken forward. In fact, in March of this year the first "6G Wireless Summit" took place, an event in which several global experts in mobile communications met to try to shape what 6G will be. Now, there are many challenges ahead, mainly give it a utility.

The 5G comes not so much to improve the speed at which we connect to Instagram, but to improve network saturation, improve latency times to reduce them to a few milliseconds and implement technologies such as Edge Computing. Su Xin, director of the 5G working group of the Chinese Ministry of Industry and Information Technology, confirmed at the time that the country was already working on 6G and that this network would improve those three aspects.

The first steps have already been taken on the road to 6G and there is talk of 1 Tbps download speed

Local media collected some words from Xin, who claimed that the 6G could reach a download speed of 1 Tbps, a thousand times more than the connection offered by Google Fi (1 Gbps). Jessica Rosenworcel of the US FCC said that 6G would be implemented in the terahertz frequencies and that could even introduce the blockchain in some way. All these are just words, because to implant 6G you will first have to expand 5G, amortize it and develop your successor.

To put it in context, only in Europe is it estimated that the investment needed to implement 5G will be between 300,000 and 500,000 million euros by 2025, and we speak only of Europe. If we consider the rest of the globe, the investment is triggered ad infinitium. In short, 5G has a long way to go, but the road to 6G is even longer.
