That’s a lot of variables across the top and down the side just to get to 9.6 Gbps. To give you an idea, check out this website that has a table of possible data rates. Humans can build a car that will break the sound barrier, but it’s not an innovation you or I can use to go grocery shopping with.Īs sexy as it sounds to move data at 46 Gbps, it’s not something that’s useful in 99.9 percent of Wi-Fi applications. In the real world, that’s not always feasible. To achieve those crazy-fast rates, many things need to fall into place. Not to point the finger, but only you can answer that question. Unfortunately, only one person can answer the question, “Do I buy Wi-Fi 6E or wait for Wi-Fi 7?” and it isn’t me. It’s also the requirements to get that sexy number of 46 Gbps. In Wi-Fi, speed is often the primary number that drives people to the newest technology, but it comes with a cost. I know I’m throwing many numbers at you, but there’s a good reason. For the average network, it’s hard to beat a well-designed Wi-Fi 6 network with quality hardware. Also, both have few to no client devices to use all these new developments. If TVs can be 4K, why not Wi-Fi? This new QAM rate, combined with the 320 MHz wide channel, makes it possible to achieve 46 Gbps.Īs for similarities, both include the 6 GHz band, have really fast speeds, and have really wide channels. Wi-Fi -QAM and Wi-Fi 7 is expected to be 4096-QAM.
Quadrature amplitude modulation is the technique of encoding data on a radio signal. For reference, the entire 2.4 GHz band is only 83 MHz wide, so this is a huge increase. The maximum channel bandwidth in the 5 GHz band was 160 MHz wide, but, with the new spectrum in the 6 GHz band, that’s increasing to a channel bandwidth of 320 MHz wide. When people don’t have enough resources to accomplish tasks, they say, “We don’t have enough bandwidth to accomplish that.” Stolen directly from wireless, we now have more bandwidth to move more data. That’s reaching the plaid range 3 on the speedometer. Wi-Fi 6 maximum speed is 9.6 Gbps (which, honestly, is fast), while Wi-Fi 7 is expected to have a maximum speed of 46 Gbps. The three biggest are the change in theoretical maximum speed, increased channel width, and the QAM.įirst, the speed difference. The best way to answer this is to look at the many differences in the two protocols. The next question that came up was, “What about Wi-Fi 7?” Wi-Fi 6E or Wi-Fi 7? The additional spectrum is a monumental achievement, yet it didn’t take long for Wi-Fi professionals to look forward. 2021 saw the first hardware released that supported all three bands: 2.4, 5, and 6 GHz.
As Wi-Fi has grown in popularity and transitioned from a “nice-to-have” to a “must-have” service, Wi-Fi professionals have struggled to fit this increasing demand into a spectrum allotment that was set before most people had internet in their houses-much less, wireless internet.

The full effect of the 6 GHz band will vary 2 depending on where you’re sitting however, no matter how much spectrum was released for your area, this is a HUGE deal. The Wi-Fi world celebrated two important innovations in a short time: Wi-Fi 6 (802.11ax) gave us OFDMA 1 and, shortly after, a whole new spectrum became available-the 6 GHz band. Although many amendments followed 802.11a, few were as well known as the common PHY rate amendments (802.11a/b/g/n/ac/ax).
