What is Wi-Fi 6?

Wi-Fi 6 is the sixth generation of Wi-Fi and is also known as "AX WiFi" or "802.11ax WiFi." It builds upon the strengths of the previous generation, Wi-Fi 5 (802.11ac), by offering greater speed, improved efficiency, and reduced network congestion in heavy bandwidth usage scenarios. Here’s a rundown of what Wi-Fi 6 brings to the table:

Improved Speed

Wi-Fi 6 allows for faster data transfer speeds, theoretically up to 9.6 Gbps across multiple channels, compared to Wi-Fi 5’s peak of 3.5 Gbps. This doesn’t necessarily mean that individual devices will be faster, but the network can handle fast speeds on more devices at once.

Increased Capacity

Wi-Fi 6 uses Orthogonal Frequency Division Multiple Access (OFDMA), a key feature that allows for better handling of multiple devices. This means it can efficiently manage traffic from numerous devices all vying for bandwidth, from smartphones and laptops to IoT devices.

Better Performance in Crowded Areas

Wi-Fi 6 shines in crowded environments like stadiums, airports, or your own device-packed home. It utilizes Basic Service Set (BSS) Coloring which reduces interference from nearby Wi-Fi networks, a significant advantage when multiple networks operate in close proximity.

Improved Power Efficiency

Target Wake Time (TWT) is a feature that allows devices to determine when and how frequently they will wake up to send or receive data. This improves device battery life as it can sleep more often, conserving power.

Enhanced Security

Wi-Fi 6 also incorporates the latest security protocols, including WPA3, which makes it harder for hackers to crack passwords by using advanced brute-force techniques and enhances data encryption.

Range Boost

While Wi-Fi 6 doesn’t necessarily increase the range of a Wi-Fi signal, the technologies it uses can offer better data rates at a given distance, which may improve the overall coverage.

When to Use Wi-Fi 6

If your home or business has a lot of devices that need to connect to the internet simultaneously, or you require the fastest possible speeds for tasks like streaming 4K/8K video or online gaming, Wi-Fi 6 could be significantly beneficial.

However, to fully take advantage of Wi-Fi 6’s capabilities, not only do you need a Wi-Fi 6 compatible router, but also devices equipped with Wi-Fi 6 wireless network cards. As of my last update in April 2023, Wi-Fi 6 is increasingly being supported on new devices, but it’s worth checking compatibility before you invest in new equipment.

In essence, Wi-Fi 6 isn’t just about better speed for a single device; it’s about a more robust network that’s capable of supporting the burgeoning landscape of a hyper-connected world.
