WiFi 6 has officially been released

WiFi Union officially unveiled the new generation of the technology. WiFi 6 is designed to improve performance and focus on crowded networks.

There was talk of the next generation of WiFi last year, but yesterday the Wi-Fi Alliance officially unveiled Wi-Fi 6. WiFi 2 is finally ready, and soon many tech companies are looking to use it in their new products, and we will soon see “Wi-Fi 6 support” as new product features.

WiFi 7 includes new technologies that make WiFi more optimized. This is very important because of the range of WiFi performance. We all have devices that connect to Wi-Fi networks, from smartphones to gadgets and wearables . Connecting multiple devices simultaneously to a Wi-Fi network is also unexpected. These new technologies are improving the connectivity of multiple devices to a Wi-Fi network.

So the goal of WiFi is to speed up a crowded network. The fastest speed on WiFi paper has also been increased, from 1.5 Gbps to 3.5 Gbps. But speed on paper is useless until you get it. The important point about WiFi 2 is the tools that enable faster WiFi performance and more data transfer per unit time. Thanks to these tools, we’ll see higher speeds of WiFi than ever before. These achievements are more important in crowded networks. Wi-Fi has also seen a huge improvement in security.

Of the new Wi-Fi technologies, OFDMA, MU-MIMO, TWT and 1024-QAM can be mentioned. Independent Frequency Split Access (OFDMA) is a technology that shares channels to increase performance and reduce latency. Multiple Output Multiple User Input (MU-MIMO) allows more devices to connect to data and transmit data over time. 4MHz channels increase bandwidth. Target Awakening Time (TWT) improves the battery life of connected devices (especially IoT devices). Beam transfer increases the data transfer rate at each interval and the device’s 1024-QAM Wi-Fi input, meaning that more data can be encoded at the same interval.

WiFi 6 will soon be supported on at least millions of devices

Of course, the introduction of Wi-Fi is more symbolic, as the Wi-Fi licensing program is not necessary, and companies have been launching Wi-Fi-enabled devices for several months. But the WiFi union includes members from large and small companies in the tech industry, and its practices reflect the characteristics of wireless technology and the technologies that these companies are interested in developing and delivering.

The official release of Wi-Fi 1 is accompanied by another major announcement – the launch of Apple’s new iPhones ( iPhone 2 and iPhone 6 Peru ) that support Wi-Fi 1. This means that WiFi 6 will soon be supported by at least millions of devices and adoption of this new technology by users and technology companies will be very fast.

Of course, none of the new Apple devices have been certified by the Union, but it’s hard to imagine poor Wi-Fi working on these phones. According to the Samsung Galaxy Note 4, it is the first official smartphone to be licensed to use the new standard. Other older products are only licensed to operate and have the bare minimum, but since Wi-Fi uses new hardware, older devices must incorporate new hardware to get licensed. We will soon see gadgets with this new hardware and support for new WiFi.

What is Wi-Fi 6? (also known as AX WiFi)

Wi-Fi 6 is the next generation standard in WiFi technology. Wi-Fi 6 also known as “AX WiFi” or “802.11ax WiFi” builds and improves on the current 802.11ac WiFi standard. The Wi-Fi 6 was originally built in response to the growing number of devices in the world. If you own a VR device, multiple smart home devices, or simply have a large number of devices in your household, then a Wi-Fi 6 router might just be the best WiFi router for you. In this guide, we’ll go over Wi-Fi 6 routers and break down how they’re faster, increase efficiency, and are better at transferring data than previous generations.

Explosively Fast WiFi up to 9.6 Gbps

Ultra-Smooth Streaming
802.11ax 1024-QAM  4× Longer Symbol  160 MHz Channel 9.6 Gbps
802.11ac 256-QAM 6.9 Gbps

Wi-Fi 6 uses both 1024-QAM to provide a signal packed with more data (giving you more efficiency) and a 160 MHz Channel to provide a wider channel to make your WiFi faster. Experience stutter-free VR or enjoy stunningly vivid 4K and even 8K streaming.

4x More Capacity for More Devices

Ideal for Crowded Networks
802.11ax 8×8 DL/UL MU-MIMO  OFDMA  BSS Color 4X
802.11ac MU-MIMO

Wi-Fi 6 uses 8×8 uplink/downlink, MU-MIMO, OFDMA, and BSS Color to provide up to 4x larger capacity and to handle more devices. Come home to a virtually flawless smart home experience or throw house parties with a network built  to handle all your guests and their devices.

Pack More Data ­
With 1024-QAM

25% faster than 256-QAM

With 1024-QAM, each symbol carries 10 bits rather than 8 bits, improving raw speeds by 25% compared to 802.11ac 256-QAM. Watch Netflix at home or live stream Twitch Broadcasts from your home computer – with 1024-QAM, streaming just got that much better.

More Speed and

Greater Stability

4x Longer OFDM Symbol

OFDM is a symbol that transmits data. It divides its data among smaller sub carriers for more stability and wider coverage. AX WiFi uses a 4x longer OFDM symbol to create 4x more sub carriers. Because of this, Wi-Fi 6’s longer OFDM symbol provides increased coverage and makes it 11% faster. Enjoy rock solid coverage from your garage to the second story and get ultra-fast connections for all your smart home, mobile, gaming and desktop devices in between.

More Bandwidth on a Wider Channel

160 MHz Channel Width

Wi-Fi 6 expands the WiFi band from 80 MHz to 160 MHz, doubling the channel width and creating a faster connection from your router to the device. With Wi-Fi 6, you can enjoy 8K movies, large file downloads and uploads, and responsive smart home devices – all without buffering.

Increased Efficiency with OFDMA

Make Latency A Thing of The Past

The Wi-Fi 6 standard uses OFDMA for increased efficiency. Imagine your WiFi connection as a series of delivery trucks delivering data packets to your devices. With 802.11ac WiFi, each delivery truck or “packet” could only deliver one parcel to one device at a time. But with OFDMA, each truck can deliver multiple parcels to multiple devices simultaneously. This vast improvement in efficiency works for both uploads and downloads.

Figure below shows the working scenario of only one antenna.

Connect to

More Devices Simultaneously

With 8 x 8 MU-MIMO

With traditional MU-MIMO, multiple users can access the router simultaneously without any noticeable decreases in bandwidth quality– up to a point. However, with 8 x 8 MU-MIMO, more than 8 streams are available for users to choose from. And whereas 802.11ac MU-MIMO only works for downloads, 8 x 8 MU-MIMO works with both uploads and downloads. This means that whether you’re streaming, downloading, torrenting, playing VR/AR, MMO’s or RPG’s; with Wi-Fi 6’s 8 streams, there’s more than enough bandwidth for everyone.

Minimize WiFi Conflicts with Your Neighbor

With Wi-Fi 6’s BSS Color

Interference from your neighbors’ wireless networks can cause issues with your wireless signal. BSS (Base Service Station) Color, marks frames from neighboring networks so that your router can ignore them. If you’ve ever lived in an apartment or close to your neighbors, this means that your router just became that much more efficient – no extra work required.
