What is WiFi 6?
What is WiFi 6?
If Seinfeld was still around, amid discussions of a myriad of newfangled trends, main man Jerry Seinfeld may well ask: “What is the deal with WiFi 6?” And while I won’t even try to wax lyrical about his observational style of answering such a rhetorical question, what I can do is tell you the short answer is WiFi 6 is the latest wireless standard.
Sometimes WiFi 6 is called by its full jargon name, IEEE 802.11ax, and while a lot of that name isn’t particularly important, those two letters on the end – ax – are what you’re looking for on a product spec sheet to confirm whether it supports WiFi 6. These days, there’s a range of WiFi 6 devices, including WiFi 6 smartphones like the iPhone 12 and Samsung Galaxy S21 ranges, which can tap into the speedy perks of the latest wireless standard by connecting to a WiFi 6-compatible router or modem-router.
WiFi 6 vs WiFi 5
Wireless connectivity has been around since 1997 with the launch of the original 802.11 wireless standard. Back then, wireless speeds were restricted to 2Mbps, whereas 2013 saw the arrival of WiFi 5 and theoretical speeds of at least 433Mbps. WiFi 6 launched in 2019 and can achieve theoretical speeds of at least 600Mbps but up to 9,608Mbps.
The table below shows the core differences between the six WiFi generations.
|WiFi 3 (revision)||802.11g||6–54Mbps||2.4GHz||2003|
It’s important to note that the top speeds per WiFi generation are theoretical. You might consider upgrading to WiFi 6 over WiFi 5 for the speed benefits. The other big perk is the increased network capacity so more devices can connect simultaneously, which is particularly important moving forward as the average home has more and more connected devices.
Like previous WiFi generations, WiFi 6 is backwards compatible with earlier versions, meaning if you have WiFi 6 devices, they can still connect to WiFi 5 (or older) routers and, similarly, WiFi 5 (and older) devices can connect to a newer WiFi 6 router.
WiFi 6 speed in reality
In extremely optimal conditions, you can expect device speeds of up to 1.523Gbps, but there are several big disclaimers. To reach these speeds, you’re effectively dealing with local network transfers and not online speeds. Why? Australian internet currently maxes out at 1Gbps tops (NBN Ultrafast), with 250Mbps NBN Superfast a quarter of the max speed, and NBN Fast (100Mbps) the more ubiquitous kind of broadband that’s 10 times slower than the max speed of NBN Ultrafast. Basically, don’t look at a WiFi 6 upgrade if you’re after faster internet speeds.
Even with ultrafast internet, you need both a WiFi 6 device and a WiFi 6 router to start to tap into these kinds of speeds. Finally, typical wireless networking disclaimers come into play. Speeds are ultimately determined by how far away you are from the router, what interference may impact performance, and which frequency you’re connected to (e.g. 2.4GHz or 5GHz).
If you want to take advantage of WiFi 6 speeds when it comes to internet, your best bet is an NBN Ultrafast plan. The NBN Ultrafast plans below are ranked in terms of popularity.
Though not as fast, there are more options when it comes to NBN Superfast, and you can see the top 10 picks below in terms of popularity.
The majority of fixed-line NBN users (i.e. those in metro areas) can get faster internet speeds by opting for NBN Fast. Below is a breakdown of the top 10 NBN Fast plans in terms of popularity.
WiFi 6 vs WiFi 6E
WiFi 6 hasn’t been around for too long but there’s already a revision: WiFi 6E. For years, the routers in our homes have broadcasted over either 2.4GHz or 5GHz bands. WiFi 6E supports the 6GHz band, which means access to more WiFi channels and, therefore, reduced network congestion and fewer dropped signals. Other benefits include extremely low latency, higher-capacity networks, extended battery life for compatible devices, and gigabit speeds.
While the FCC has approved the use of the 6GHz band in America, it’s up to the ACMA in Australia as to whether the band will be approved for use Down Under. Even if the 6GHz band is approved for unlicensed use in Australia, tapping into its perks will require WiFi 6E router and WiFi 6E device compatibility requirements.
WiFi 6 routers and WiFi 6 modem-routers
At the time of writing, WiFi 6 modem-routers weren’t really a thing in Australia (outside of importing a rare model from overseas), but WiFi 6 routers are growing in popularity. Prices range from around $200 all the way up to $900 for a WiFi 6 router. D-Link, Netgear and Asus are the brands to look for in Australia, with the D-Link DIR-X1560 an entry-level option, the Asus RT-AX58U a mid-range choice, and the Netgear Nighthawk XR1000 a more expensive, fully featured pick.
What about WiFi 6 mesh routers?
For larger homes or even smaller ones that are prone to wireless signal interference, mesh networks offer an easy-to-use unified solution for full-home connectivity. You can read more about WiFi systems here, but the reality is that WiFi 6 mesh routers are becoming more popular for future-proofing homes.
The Netgear Nighthawk Mesh WiFi 6 System is a discrete and speedy performer that’s comparatively cheaper stacked next to the competition. The TP-Link Deco AX1800 is more of a mid-range WiFi 6 mesh alternative, or you can spend a lot of money on the Netgear Orbi WiFi 6 range for epic coverage.
WiFi 6 devices
