The 5G mmWave is a little closer: the Government dates the auction of the 26 GHz band in the second half of 2022


After multiple portraits, in mid-2021 the auction of the 700 MHz bands for the deployment of 5G concluded. These bands, essential to bring 5G to the entire national territory, are not the only ones that will have to be auctioned, since 5G in millimeter band or 5G mmWave he also has to make his way.

For this, it will be necessary for the Government to tender the 26 GHz band. Today we have learned that the auction of this band will be in the second half of 2022that is, next year. However, a public consultation must first be carried out with the main market players to lay the foundations and this consultation has already been published.

5G mmWave time

According to Ministry of Economic Affairs and Digital Transformation, the objective of this public consultation is know the demand and the management and exploitation model of the 26 GHz band, “one of the bands identified as priority” for the development of 5G, along with the 700 MHz and 3.5 GHz bands.

In the words of the Ministry, this consultation will “collect the contributions from telecommunications operators, manufacturers, industries and sector associations, among other agents“to have an” updated vision about the existing demand for this frequency band and its applications; authorization and business models; the territorial scope of the licenses, as well as the existing availability of equipment and the associated value chain “.

This consultation is the previous step to the auction of the 26 GHz band, something that is scheduled for the second half of 2022. It will be from then on when operators will have to compete to keep a part of the radioelectric spectrum. We will have to wait until then to know the result, but at least we have already started to handle some dates.

What is the 5G mmWave?

Although we have explained the 5G mmWave in detail in this article, a quick summary is that this technology promises us a speed and latency at the height of fiber optics. This is possible because the upper part of the radio spectrum is used, and therefore the gigahertz part, not the megahertz part.

The problem with high frequencies is that they fade right away, so they do not reach great distances. It is the complete opposite of what happens with the lower frequencies. To understand it better, we can imagine a road.

The 5G mmWave is like a short road, but with lots of lanes to go fast

A road in the millimeter band is shorter, but it has many lanes. They can circulate many cars or few cars at a very high speed. A highway in the megahertz band goes a long way, but has few lanes and fewer cars can circulate at slower speeds. The millimeter band has more capacity in more limited spaces, while the other goes further and does not have as much capacity. So the idea is to combine both technologies.

If we take that to numbers, in the millimeter band, which is around 26 GHz, each operator can be assigned without problem 100 to 800 MHz, while with the 700 MHz bands they are left with few blocks of 10 MHz (For example, Vodafone was left with two 10 MHz blocks). More bandwidth, more capacity, more download speed.

Precisely because of this range problem, the 5G mmWave will play an interesting role in very crowded spaces or in which connection speed is a priority. For example, in train stations, airports, sports stadiums and convention centers. They are relatively small areas with a lot of influx of people, so the 5G mmWave can work perfectly.
