WiFi 6 – The Basics Canadians Should Know

WiFi 6 marks a significant milestone in wireless technology.

Officially known as 802.11ax, WiFi 6 is not just another incremental upgrade; it’s a revolutionary leap forward. This technology promises to reshape how we interact with the digital world, offering faster speeds, greater capacity, and improved efficiency.

In this article, we’ll delve into the intricacies of WiFi 6, exploring its features, benefits, and the impact it will have on both individual users and the broader technological landscape.

What Is WiFi 6?

Technical Specifications

WiFi 6, known technically as 802.11ax, is designed to operate in all bands between 1 and 6 GHz, as regulations permit. It brings several technical advancements over its predecessor, WiFi 5 (802.11ac). Key among these is the support for Orthogonal Frequency Division Multiple Access (OFDMA), a technology that allows for more efficient channel use, and Multi-User, Multiple Input, Multiple Output (MU-MIMO), which enables more data to be transferred at once.

Key Features of WiFi 6

The standout features of WiFi 6 include:

• OFDMA: Enhances efficiency by allowing multiple users with varying bandwidth needs to be served simultaneously.
• MU-MIMO: Increases channel capacity to allow more data transfer, which is ideal for bandwidth-intensive applications.
• Target Wake Time (TWT): This feature significantly improves the battery life of devices by scheduling when to wake up and communicate with the router.

The Evolution of Wi-Fi 6 Standards

The journey from the inception of WiFi to the advent of WiFi 6 is a tale of continuous innovation and improvement. The WiFi journey began with 802.11b, a standard that now seems rudimentary compared to the capabilities of today’s technology. Each subsequent standard, from WiFi 1 (802.11b) to WiFi 5 (802.11ac), enhanced speed, range, and overall performance. WiFi 6, or 802.11ax, stands at the pinnacle of these developments, integrating all the cumulative advancements into a singular, robust standard.

Benefits of WiFi 6 for Users

WiFi 6 is more than just a new standard; it’s a significant leap forward in wireless technology that benefits users, especially in densely populated areas or households with multiple devices. Let’s explore these benefits in detail:
