WiFi networks have evolved a lot in recent years, but they will do much more in the coming years. The arrival of WiFi 6 (previously known as 802.11ax) is only the tip of the iceberg of the news that we will have in 2021. Without going any further, this will be the year of WiFi 6E, which is also called 6GHz WiFi. Until now, we had wireless networks in 2.4 GHz and 5 GHz, but more and more territories approve the use of 6 GHz. This, in addition to more speed, will bring us new wireless channels for the WiFi connection.
In January 2020, the Wi-Fi Alliance presented the WiFi 6E or what is the same, the first time that this technology could be provided in the 6 GHz band. The big problem is that this band was not authorized at that time to The use of this technology and the different territories have been doing it over the months. USA It was one of the first and this week Saudi Arabia did it.
Specifically, on March 30 it was confirmed that in that country the 5.925-7.125 GHz bands were enabled for WiFi 6E after the decision of the Saudi Arabia Communications and Information Technology Commission (CITC). The Wi-Fi Alliance keeps an updated map with the countries or continents that are enabling these frequencies for the WiFi 6E, although we have some differences between them. For example, in Europe it will be allowed to use the frequencies between 5945 and 6425 MHz.
After the United States or Saudi Arabia, when will it arrive in Spain?
The United States or Saudi Arabia are only two of the countries that have adopted these frequencies for the WiFi 6E, but they are not the only ones. Furthermore, we know that the European Union has already made the decision and that only a few bureaucratic steps remain for its entry into force. The difference between Europe and other territories will lie in the amount of spectrum to be allowed for this technology.
While in the United States they have opened the spectrum 5925-7125 MHz, in Europe it will be done with 5945-6425 MHzIn other words, we will have fewer wireless channels for this technology. Here we have part of the band proposed by the IEEE (Institute of Electrical and Electronics Engineers) and the Wi-Fi Alliance occupied by other types of radio technologies.
Instead of having up to 14 80 MHz channels and 7 additional 160 MHz channels, the new channels that we will have in Spain and in Europe will be different. This is because in other territories they divide 1200 MHz of spectrum into 160, 80, 40 or 20 MHz channels, while here we can only have 480 MHz.
