By doubling the number of supported MU-MIMO streams to 8×8 MU-MIMO, Wi-Fi 7 can also talk to 16 devices at once. That capability could help your older devices as well — if, and it’s a big if, your router comes with 16 antennas. Many 6E routers, for example, which can support up to eight antennas, only come with four, while most Wi-Fi-enabled devices, such as phones and laptops, only come with two antennas.
In other words, to get the most from Wi-Fi 7, you need all your gear to support the new standard. As always, the slowest link in your network connection will determine how much speed you get.
What all that means for you is that with the right equipment, you’ll be able to enjoy 8K movies, augmented reality/virtual reality gaming, and faster-than-ever large file downloads.
For home networks, Wi-Fi 7 enhances the performance of smart home devices, providing a more reliable connection for Internet of Things technologies. The improved bandwidth and speed are perfect for families, like mine, which have multiple devices streaming high-definition content simultaneously. Your overall Wi-Fi performance, whether it’s just you or your family and friends, will see a dramatic improvement.

In businesses, Wi-Fi 7 can support more devices with minimal interference. This capability makes it ideal for large offices and coworking spaces. The improved speed and stability facilitate seamless video conferencing and efficient cloud-based applications, which are essential for modern companies.
All that’s the good news. The bad news is that the 6 GHz wireless spectrum uses shorter wavelengths. Short wavelengths are great for fast data transfers at close range, So, they’re great for connecting to your Wi-Fi 7-enabled HDTV a few feet away from your router. But short wavelengths are poor at connecting at long distances and suffer greater interference from physical obstructions, such as dense walls or floors in a building. There, you’re still using the 2.4GHz and 5GHz connections that you’ve been using since 802.11n Wi-Fi networks showed up in 2008.
Eventually, the Federal Communications Commission (FCC) will finalize the Automated Frequency Coordination (AFC) system. This system will allow Wi-Fi 7 devices to operate at increased power levels. The fix, which firmware upgrades will distribute, will increase 7’s range and overall performance.
Some Wi-Fi 7 routers are already available, including: the Eero Max 7, $1,699.99; Netgear’s Orbi 970 Series, $2,299.99; and the Netgear Nighthawk Tri-Band WiFi 7 Router, $699.99. What you’ll notice from those figures is that Wi-Fi 7 routers are not cheap. And I don’t see their prices dropping anytime soon.

Now, you may be asking yourself, if the Wi-Fi Alliance only just started certifying Wi-Fi 7 devices, how can these routers already be available? Easy, this standard has been in the works for a long time. If you already have a Wi-Fi 7 router or you’re going to get one, you can count on getting a firmware update soon to ensure that your devices will be compatible with the final standard.
If you really need bleeding-edge speed, you can go ahead and get Wi-Fi 7 devices today. After all, Wi-Fi 7, with its enhanced speed, increased bandwidth, and improved stability, is a significant leap forward in wireless technology. But, honestly, I think most people should wait until more devices support Wi-Fi 7 and the prices come down.
