The next generation of Wi-Fi Standards: Wi-Fi 6 and beyond
Will Liu, Managing Director of TP-Link UK explains how the arrival of Wi-Fi 6E will meet the demands of increasing Internet devices and will most importantly boost networking quality.

020 represented a milestone for mobile networking development, with the rapid development of 5G and 5G-compatible devices. Now that we are on the path to global adoption of the latest
Wi-Fi standard and next generation of connectivity, Wi-Fi 6 and further still, Wi-Fi 6E. Looking even further ahead, Wi-Fi 7 is expected to arrive in 2023 - and businesses need to be ready for this rapid pace of development. As standard Dual-Band wireless routers broadcast both 2.4GHz
and 5GHz Wi-Fi signals, they largely overlap because the 5Ghz channels are significantly limited, which leads to tremendous 2.4Ghz and 5GHz wireless interference between devices which are essentially competing with each other. Innovation of the W-iFi 6 Mesh router allows combating this issue
with 6GHz, which has seven 160MHz channels, meaning there will not be any overlaps as long as different channels are selected. 6GHz wireless is designed to resolve overlapping and interference problems, providing users with the best 4K/8K streaming, gaming and high speed downloading experience. Wi-Fi 6E is an upgraded version of Wi-Fi 6, it extends Wi-Fi 6 into
the 6GHz band. Wi-Fi 6E works with the same standard as Wi-Fi 6 but with an extended spectrum. 6GHz is the new frequency band ranging from 5.925GHz to 7.125GHz, allowing up to 1,200MHz of additional spectrum. Unlike the existing bands on which channels are currently crammed into the limited spectrum, the 6GHz band exists without overlap or interference. As many organisations now choose to bring their employees to
the office following a hybrid working system, they need to focus on supporting their teams with good connectivity to allow for a smooth transition. Remote working may allow for better connection given fewer Wi-Fi channels are in use, but this shouldn’t be holding organisations back. Mesh is a Wi-Fi system created to eliminate dead zones and deliver
uninterrupted Wi-Fi throughout the entire home. Higher speeds and extra channels provided by Wi-Fi 6 allow quick and easy change of the size of the network and to reserve a channel for home office purposes with the rest of the household enjoying connection for leisure. In a business setting, which requires a lot more reliable connectivity
options for multiple devices simultaneously, network congestion becomes a severe problem for the organisation. This is where Wi-Fi 6 becomes a solution for providing the same performance and

convenience as working from home with the frequency band up to 7.125GHz. With those parameters, Wi-Fi 6 seems essential to realise its full potential in speed improvement and latency reduction for mitigating those issues. Also, each node in a mesh web both receives and decrypts information. This provides a lot of redundancy, which helps keep the network running even if a problem arises making mesh a perfect match for Wi-Fi 6. The addition of the new 6GHz spectrum significantly boosts wireless
networking performance and helps Wi-Fi 6 meet its intended purpose of higher capacity and less interference. This game-changing level of speed is equipped to tackle the digital demands of our connected lives, in business, social and home environments, but there are some key considerations for users looking to move to a Wi-Fi 6 future. The addition of the new 6GHz spectrum significantly boosts
wireless networking performance and helps Wi-Fi 6 meet its intended purpose of higher capacity and less interference. This game- changing level of speed is equipped to tackle the digital demands of our connected lives, in business, social and home environments. As already mentioned Mesh technology is meant to radiate the most powerful Wi-Fi as accessing from any space without interference. Unlike Wi-Fi 6 operating at the 2.4GHz and 5GHz bands, Wi-Fi
6E and the Wi-Fi 6E-enabled devices can exclusively use the entire 6GHz band. When using Wi-Fi 6E, there is no need to compete with legacy devices and slow down the speed of data transmissions, this demonstrates how easy shift would be for both business and private users. Wi-Fi 6E will be able to meet both the demand of the rapid increase
of Internet devices in the future and the need for better networking quality. The performance boost in total is game changing. Given how big a part the digital world has in the daily lives of many
consumers, undeniably a new, open spectrum is needed to solve the problem of high usage with more devices, and increased data traffic. Wi-Fi 6E takes connectivity in the workspace or at home to the next level. This means no more buffering videos or disrupted video calls. Just as the world moved on from the dial-up Internet, there is now
much more within consumers’ reach when it comes to innovative solutions to meet the demands of a connected lifestyle. Over the next five years, we can certainly expect to see the utilisation of Wi-Fi 6 and Wi-Fi 6E by many organisations making them a foundation of workplace networks.
