Wi-Fi 6 was launched last year, bringing numerous improvements to wireless networks, such as higher transfer speeds, lower latency and more stability. At the beginning of 2020, a new standard was introduced, Wi-Fi 6E, which is an improvement on this new standard, presenting the same characteristics, but using the 6 GHz spectrum.
The use of the 6 GHz spectrum, however, was reserved for licensed use. On April 23, the United States Federal Communications Commission (FCC) approved the unlicensed use of the spectrum, releasing its use by any device, as long as it is responsible. In addition to devices using the new standard, operators will also be able to take advantage of 6 GHz to expand their 5G networks.
What is Wi-Fi 6E?
To put it briefly: Wi-Fi 6E is the same Wi-Fi 6, but with the possibility of operating in the 6 GHz spectrum. Although the new standard makes use of the same technologies as the previous one, there are significant improvements provided by the width higher bandwidth.
Using the 6 GHz spectrum, Wi-Fi 6E offers 1,200 MHz of extra bandwidth. This can be divided into 14 channels of 80 MHz or 7 channels of 160 MHz.
Theoretically, transfer speeds are not higher, but this bandwidth is a major advantage in areas of high congestion, such as public places, which should improve the stability of the network as a whole. More stable networks ensure maximum transfer rates for longer, in this case potentially over 1 Gbps. The way channels are distributed also favors less interference and lower latency, just 1 ms.
Just like Wi-Fi using the 5 GHz standard, the one using 6 GHz has less range and suffers more interference with obstacles than the 2.4 GHz one.
To use Wi-Fi 6E, it is necessary that the entire network infrastructure is already prepared for the new standard, both the equipment that generates the signal (router) and the receiver equipment (notebooks and smartphones).
The first ones routed with this new technology should be launched in late 2020.
