One of the biggest challenges facing WiFi professionals is to keep up with <\/span><\/i>really demanding scenarios.<\/span><\/i><\/a> By this we mean environments where a large number of people want to use the same wireless network at the same time. There are many examples: from sports stadiums to train stations, from shops to large events. In this sense, the arrival of WiFi 6E networks will mean a leap forward. Do you want to know why? Let’s get started!<\/span><\/i><\/p>\n

<\/h2>\n

What is WiFi 6E?<\/b><\/h2>\n

We can say that WiFi 6E is an extension of the 802.11ax (WiFi 6) standard, the latest standard for wireless local area networks from the IEEE.<\/span><\/p>\n

So what are the differences between WiFi 6E networks and those that are simply WiFi 6? Basically, devices that support WiFi 6E have hardware that makes them ready to operate in a new spectrum band, which is the 6 GHz band, with 1,200 MHz of new bandwidth and a wide variety of channels. A new band to add to WiFi 6’s own bands (the classic 2.4 and 5 GHz bands).<\/span><\/p>\n

 <\/p>\n

Main features of WiFi 6E<\/b><\/h3>\n

What are the practical consequences of implementing WiFi 6E? Its main advantages are related to the use of a new band that is little used by other technologies. The absence of interference and low noise will allow very attractive transmission rates for high-demand applications, such as 4K video. This band, however, will have a shorter range (coverage), especially in indoor environments with thick walls and floors.<\/span><\/p>\n

WiFi 6E allows new additional channels to be used. These can range from 56 20 MHz channels, 28 40 MHz channels, 14 80 MHz channels and 7 160 MHz channels.<\/span><\/p>\n

All this translates into faster connections, less interference, fewer dropped packets and retransmissions, leading to greater <\/span>efficiency and stability <\/span><\/a>in environments where there are a significant number of connected users in close proximity to the access points.<\/span><\/p>\n

Therefore, WiFi 6E connections will be really useful in situations where there are large concentrations of people in places such as stadiums, concert halls, shopping centres, airports, <\/span>hotels<\/span><\/a>, <\/span>trains<\/span><\/a>, etc.<\/span><\/p>\n

 <\/p>\n

The basis of WiFi 6E: the 802.11ax standard<\/b><\/h2>\n

WiFi 6E can be seen as an extension of the latest WiFi 6 technology, although it is a far cry from the early proposals we are seeing for a hypothetical WiFi 7 back in 2024. In this sense, WiFi 6E simply includes an attractive portion of additional spectrum for transmitters.<\/span><\/p>\n

 <\/p>\n

WiFi 6 was introduced by the WiFi Alliance in 2020, so it is a standard that has many new benefits for its users. How did we get to this point? What did WiFi 6 mean compared to its predecessor, WiFi 5 or 802.11 ac?<\/span><\/p>\n

 <\/p>\n

One of the main performance improvements of WiFi 6 is that it brings many of the improvements of 802.11ac (MU-MIMO, bandwidths above 40 MHz, 256-QAM modulation) also to the 2.4 GHz band, whereas WiFi 5 only does so in the 5 GHz band. In addition, the bandwidth of the WiFi 6 channels can be divided into sub-channels to solve the problem of high device density.<\/span><\/p>\n

 <\/p>\n

WiFi 6 connections have a theoretical maximum speed of 9.6 Gbps, while WiFi 5 has 6.9 Gbps. These results are achieved thanks to a series of technologies that provide unquestionable advantages. Here is a summary of the most important ones:<\/span><\/p>\n
