  • Woohoo!

  • It is officially new phone season, that time of year when big tech companies roll out the latest devices that

  • offer a host of new features that make you want to throw your old phone right in the trash.

  • Things like better screens, multiple cameras that look like spider eyeballs, and support

  • for WiFi 6!

  • Wait, WiFi 6… what happened to the first 5?

  • Well it turns out, you've actually been using one of the previous iterations of WiFi, which can trace

  • their roots to 1997.

  • Back then it wasn't called WiFi 1, but the much catchier 802.11.

  • The number code was designated by the Institute of Electrical and Electronics Engineers, or

  • IEEE.

  • Since then, there have been several updates to the 802.11 standard, and each one had a

  • different letter tacked on the end, like a, b, g, and n.

  • But unless you're a diehard technophile, the letters and what they mean are hard to

  • sort out.

  • So to make things a bit easier for consumers, the next standard, 802.11 ax, will be referred

  • to as Wi-Fi 6, and previous standards will be retroactively renamed, like the last gen

  • 802.11ac is now also called WiFi 5.

  • So how is WiFi 6 better?

  • Well like you might expect, it's promising faster speeds. Industry experts predict about

  • 30% gains over WiFi 5 with theoretical maximum download speeds up to 10 Gbps in ideal conditions.

  • If you're into streaming 4K movies or want to jump into cloud gaming, those

  • numbers will make you drool.

  • One way it achieves this is by upping the number of bits the router can push out with

  • each transmission.

  • Sending information over the air is done by modulating radio waves.

  • The way the wave is affected is interpreted by the device as a one and a zero, a process called

  • quadrature amplitude modulation, or QAM.

  • A 2-QAM router can affect radio waves in two distinct ways, so each transmission could

  • only serve as a single one or a zero.

  • A 4-QAM router can send 2 digits at a time.

  • WIFi 5 routers are 256-QAM, meaning they can send 8 bits with each transmission,

  • while a WiFi 6 device is 1024-QAM, adding another 2 binary digits to each transmission

  • for a total of 10.

  • That all sounds great, but keep in mind your WiFi 6 router can only be as fast as your

  • internet service provider will allow, so depending on how you're wired into the grid and what

  • kind of plan you pay for, your mileage may vary.

  • Aside from the bump in speed limit, the exciting thing about WiFi 6 is how it delivers internet

  • to multiple devices.

  • The first improvement is the router's ability to split up the channels it's communicating

  • over, allowing different devices to get serviced directly simultaneously and cutting down on

  • latency.

  • WiFi 6 routers are also able to use the spatial differences between devices to tailor the

  • information it sends and receives.

  • And if there are multiple smart devices like thermostats and refrigerators that regularly

  • ping your router, a WiFi 6 router will put them on a schedule to ease congestion.

  • What this all means is WiFi 6 is great news for situations that deal with a lot of devices

  • all at once.

  • Stadiums and airports are ideal places for the new routers, and those with WiFi 6 compatible

  • phones, tablets, and computers will reap the benefits.

  • Otherwise unless you've got a home festooned with smart tech or pay your ISP for the very

  • best internet speeds possible, you're just fine with your old phone and router that

  • are still using the old 802.11ac.

  • Excuse me, WiFi 5.

  • While WiFi 6 certification just officially launched, the development of WiFi 7 is already

  • underway.

  • Have we ever mentioned how fast tech moves?

  • Wireless internet has been around for two decades, so when is wireless charging

  • going to be a thing? Check out Amanda's video on that here.

  • Is Wi-Fi 6 enough to make you upgrade your phone?

  • Let us know in the comments, subscribe for more, and I'll see you next time on Seeker.

Woohoo!
