WiFi Alliance and the Institute of Electrical and Electronics Engineers (IEEE) a Wi-Fi 6E
Rewrite below article in more structured way and adding headings for paragraphs. Please also add local touch of EZELINK Saudi Arabia, Riyadh and Jeddah market wherever you can. Do not reduce the number of chracters for the post. You can also add more infomration based on your knowledge and expand the article. Where possible write the text in bullet points format instead of paragraph:
The Institute of Electrical and Electronics Engineers (IEEE) , which develops networking standards, has worked in parallel with the Wi-Fi Alliance to expand the Wi-Fi 6 standard, available since 2019. As a result of this work and the agreements reached in mid-2020, the frequency band 6 GHz (5.925 – 7.125 GHz) has been licensed for Wi-Fi applications, and at the end of this year, the first device certificates were approved. Of course, devices must comply with certain transmission standards so as not to interfere with the licensed use of this band by fixed satellite and microwave services, CARS (Cable Television Relay Service) or BAS (Broadcast Auxiliary Services). The importance of Wi-Fi technology in numbers in 2021 can be seen in the graph below, compiled by the Wi-Fi Alliance. Even the latest, just-launched Wi-Fi 6E technology will provide exceptional coverage with its wide range of capabilities
WiFi technology in numbers
The economic value of Wi-Fi solutions in 2021 is estimated at $3.3 trillion , with 4.2 trillion Wi-Fi enabled devices, 2.2 trillion Wi-Fi 6 devices and 338 million Wi-Fi 6E devices shipped annually . With over 500 million public hotspots, nearly 63% of mobile data traffic is carried over Wi-Fi. Approximately 16.4 trillion Wi-Fi-enabled devices are currently in use, with a total of 37.5 trillion devices shipped to date.
Generations of Wi-Fi according to the new nomenclature
Over the past few years, the pace of change in Wi-Fi standards has increased significantly, so the standards organization decided to simplify the notation so that users can easily understand what they are dealing with. Subsequent standards have been referred to as generations,
so the latest IEEE 802.11ax standard is number 6, Wi-Fi 6. Wi-Fi 6E, which brings the capabilities of the aforementioned standard from the 2.4 and 5 GHz bands to the 6 GHz band, is actually an extension of Wi-Fi 6. Fi 6. In this way, devices that support a particular Wi-Fi standard receive the highest generation designation available, which usually ensures full backwards compatibility.
For greater simplicity, visual coding for each Wi-Fi generation has also been introduced. Manufacturers can use them on new products so that even those who are not fully versed in new technologies can easily compare different devices on Wi-Fi capabilities.
WiFi 6E, or WiFi 6 in the 6 GHz band
It is impossible to describe the capabilities of Wi-Fi 6E technology without knowing its basis – a completely new, 6th generation of the Wi-Fi standard, which has not yet managed to establish itself in the network device market. The IEEE 802.11ax standard , powered by certified Wi-Fi 6 devices, delivers the capacity, performance and range to meet today’s needs, using frequencies hitherto available for WiFi standards – 2.4 and 5 GHz. 6th generation WiFi also means the highest security and compatibility standards, as well as lower power consumption,which is also valued in solutions from the IoT, IIoT or smart home category. These solutions help to ensure optimal working conditions in virtual reality, e-learning or medical environments – key issues in times of pandemics, as well as communication in large crowds, applications requiring high bandwidth or based on the location of users
