What uses Wi-Fi 6?

Wi-Fi 6, also known as 802.11ax, is the latest generation of Wi-Fi technology, offering faster speeds, increased capacity, and improved efficiency. This article explores the key uses and applications that can benefit from upgrading to Wi-Fi 6.

What uses Wi-Fi 6?

Faster Speeds

One of the main uses for Wi-Fi 6 is to deliver much faster data speeds compared to previous Wi-Fi generations. Wi-Fi 6 supports maximum theoretical speeds up to 9.6 Gbps, a big leap over Wi-Fi 5 speeds that max out at 3.5 Gbps.

With Wi-Fi 6, activities like 4K/8K video streaming, VR/AR experiences, video conferencing, and cloud gaming can happen smoothly without buffering or lag issues. This makes Wi-Fi 6 ideal for:

  • 4K/8K Video Streaming – Services like Netflix, YouTube, and others can stream ultra high definition video content reliably to multiple devices on a Wi-Fi 6 network simultaneously.
  • Augmented Reality/Virtual Reality – AR/VR apps and platforms require very low latency and consistently high throughput to deliver immersive experiences, both areas where Wi-Fi 6 excels.
  • Video Conferencing – From Zoom to Microsoft Teams, video meetings with crystal clear audio and video are enabled by Wi-Fi 6 networks even with many participants.
  • Cloud Gaming – Playing graphics-rich cloud video games like Xbox Game Pass, Google Stadia, and Nvidia GeForce Now requires Wi-Fi 6 to work well by supporting fast speeds and low latency connectivity.

Increased Capacity

Along with higher speeds, Wi-Fi 6 also increases capacity significantly over Wi-Fi 5. More devices can connect successfully to one Wi-Fi 6 router at the same time while maintaining high performance on each device.

Wi-Fi 6 achieves this greater capacity through more efficient data encoding, allowing more data to be transmitted at once, as well as other optimizations.

The greater capacity of Wi-Fi 6 makes it effective for:

  • Smart Homes – With potentially dozens of smart devices like lights, appliances, sensors, security cameras, and more, Wi-Fi 6 can handle many more simultaneous IoT and smart home device connections.
  • Public Venues – Places like airports, stadiums, conference halls, etc can support more visitor devices at once with Wi-Fi 6 without performance degradation.
  • Schools – Teachers and students can use laptops, tablets, and phones on the network reliably despite a high device density across classrooms.
  • Offices – Wi-Fi 6 allows more employees to work effectively from the office even as more smart building systems come online.

Improved Efficiency

A less obvious but equally important capability Wi-Fi 6 introduces is significantly improved efficiency. Wi-Fi 6 optimizes how devices connect to the network and share time communicating with the router for less interference and traffic management overhead.

As a result, Wi-Fi 6 extends battery life for devices using the network. It also reduces overall power consumption for the infrastructure supporting the network.

These Wi-Fi 6 efficiency enhancements make it suitable for:

  • Smartphones and Tablets – Mobile devices will last longer unplugged when using Wi-Fi 6 networks compared to Wi-Fi 5.
  • IoT Devices – Simple home automation devices like sensors often rely on battery power. Wi-Fi 6 extends operational lifetime.
  • Laptops – Users can enjoy longer battery life for laptops regularly connecting over Wi-Fi 6.
  • Sustainable IT – Organizations can reduce energy usage with Wi-Fi 6 across access points and connected devices while supporting more traffic.

Who Should Upgrade to Wi-Fi 6?

Given its substantial speed, capacity, and efficiency improvements, Wi-Fi 6 delivers significant benefits in various usage scenarios. But who should upgrade?

Consumer and Home Upgrades

For many households, upgrading home networks to Wi-Fi 6 can enable better support for new devices and services:

  • Households with many connected smart home devices will benefit from Wi-Fi 6 capacity to prevent gadget response delays.
  • Homes regularly streaming 4K or 8K video to multiple TVs and devices will appreciate Wi-Fi 6 speeds.
  • Smartphone-centric households after longer battery life can achieve it over efficient Wi-Fi 6 networks.

Often upgrading the router is all it takes, as devices going back a few years may already have Wi-Fi 6 compatibility.

Enterprise and Office Upgrades

Businesses managing networks supporting critical services also have much to gain from a move to Wi-Fi 6:

  • Companies supporting remote and hybrid work require improved capacity for more employees to work effectively both on premises and remotely.
  • Wi-Fi 6 efficiency can reduce power and infrastructure costs significantly across campus environments.
  • Businesses innovating with technologies like IoT and AR/VR will need future-ready Wi-Fi 6 networks to build prototypes and proofs of concept.

A managed upgrade path typically involves updating wireless access points first, followed by onboarding compatible end user devices.

Are You Ready to Upgrade?

Here are a few questions to see if Wi-Fi 6 might be the right next upgrade for your home or office network:

  • Do your Wi-Fi routers struggle to deliver strong signals across all parts of your home or office space? Wi-Fi 6 supports better range.
  • Does video streaming buffer or do high bandwidth services suffer intermittent quality issues on your network? Wi-Fi 6 offers higher throughput.
  • Are more than 20 devices trying to share your Wi-Fi for much of the day? Wi-Fi 6 streams more concurrently.
  • Does your Wi-Fi quickly drain mobile device batteries or hamper wireless gadget performance? Wi-Fi 6 brings efficiency gains.
  • Is lack of coverage preventing innovative wireless services like AR/VR or cloud computing in parts of your environment? Wi-Fi 6 expands possibilities.

If you answered yes to one or more questions, Wi-Fi 6 merits a closer look for your tech upgrade roadmap.
