What is Wi-Fi 6? And Why Do I Want It?
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. 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.
- Wifi 6 offers up to 9.6 Gbps speed
- Pack More Data With 1024-QAM
- More Speed and Greater Stability
- More Bandwidth on a Wider Channel
- Increased Efficiency with OFDMA
- Connect to More Devices Simultaneously
- Minimize WiFi Conflicts with Your Neighbor
- Reduce Power Consumption
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.
Wi-Fi 6 uses 8x8 uplink/downlink, MU-MIMO, OFDMA, and BSS Color to provide up to 4x larger capacity and to handle more devices.
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. (Like expanding from a 2 lane hiway to a 4 lane)
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.
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.
Target Wake Time (TWT) allows devices to negotiate when and how often they will wake up to send or receive data, increasing device sleep time and substantially improving battery life for mobile and IoT devices.
