What is latest Wi-Fi version?

A Brief History of Wi-Fi Standards

Wi-Fi technology was first developed in the 1990s as an alternative to wired networking. Below is a quick history of the different versions over the years:

  • 802.11b – Released in 1999, operated on the 2.4 GHz band with speeds up to 11 Mbps.
  • 802.11a – Released in 1999, operated on the 5 GHz band with speeds up to 54 Mbps.
  • 802.11g – Released in 2003, operated on the 2.4 GHz band with speeds up to 54 Mbps. Backwards compatible with 802.11b.
  • 802.11n – Released in 2009, introduced multiple-input multiple-output (MIMO) technology allowing for increased bandwidth. Speeds up to 600 Mbps on both 2.4 and 5 GHz bands.
  • 802.11ac – Released in 2013, more spatial streams and wider channel bandwidths for faster speeds. Up to 6.9 Gbps on the 5 GHz band.
  • 802.11ax (Wi-Fi 6) – Latest standard released in 2019. Focuses on efficiency and performance in dense, high-traffic environments. Speeds up to 9.6 Gbps.

As you can see, each new version improves upon the last in some meaningful way, whether it be higher maximum speeds, greater range, or better connectivity for multiple devices. This brings us to the current Wi-Fi 6 standard.

Introducing Wi-Fi 6 (802.11ax)

Wi-Fi 6, also known by its technical name 802.11ax, is the newest generation of Wi-Fi technology. It builds on the advances made in previous standards to optimize performance, especially in areas with many connected devices. Key improvements include:

  • Higher Speeds – Maximum theoretical speeds up to 9.6 Gbps, a nearly 40% increase over 802.11ac. Leverages technologies like 1024-QAM and OFDMA for faster data transfers.
  • Increased Capacity – Supports efficient simultaneous transmission to multiple devices, even in very dense or crowded environments.
  • Better Power Efficiency – Target Wake Time (TWT) feature intelligently manages when devices are active. Improves battery life for mobile devices.
  • Backwards Compatibility – Works with devices supporting earlier standards like 802.11n and 802.11ac. However, maximum speeds will scale down to the lowest common denominator.
  • Enhanced Security – New WPA3 encryption protocol replaces the older WPA2 standard to better protect network traffic. Also utilizes OWE encryption.

With these improvements, Wi-Fi 6 is ready to meet the connectivity demands of future smart homes and offices filled with phones, laptops, TVs, IoT devices and more. Even as the number of devices grows exponentially, users should still expect fast, reliable wireless performance.

The Benefits of Upgrading to Wi-Fi 6

For many residential and business users, is it worth upgrading networking equipment to take advantage of Wi-Fi 6? Let’s examine some of the key benefits this new standard provides:

  • Faster File Transfers and Downloads – The sheer speed increase compared to older standards means large files, videos, and downloads occur noticeably faster.
  • Smoother 4K/8K Streaming – There’s enough bandwidth headroom for smooth streaming of high resolution video across multiple devices. No more jitter or buffering.
  • Enhanced VR/AR Experiences – Low latency and high capacity required for seamless virtual reality. Some VR headsets already support Wi-Fi 6 connectivity.
  • Better Voice and Video Calls – With greater bandwidth per device, voice and video chat apps will function flawlessly. No more garbled audio or stuttering video.
