![]() ![]() In November, TP-Link announced half a dozen Wi-Fi 7 routers with two of them already up on Amazon and due to ship in a couple of months.įor serious performance junkies, the quad-band TP-Link Archer BE24000 offers a combined 24.4 Gbps bandwidth. A company called H3C announced (and supposedly released) its Magic BE18000 last summer, but it’s not for sale in North America and we haven’t seen it for sale anywhere else either. We haven’t seen any Wi-Fi 7 routers or client adapters shipping yet, but several products have already been announced and a couple are even up for pre-order. When Will Wi-Fi 7 Devices be Available to Purchase? Puncturing allows the unused 280MHz of bandwidth to be allocated for a client. In the example above provided by Intel, 40MHz of wireless spectrum is in use (out of a 320MHz total channel bandwidth). In addition, Wi-Fi 7 supports preamble puncturing, which enables a client to use spectrum that another user otherwise occupied. Wi-Fi Preamble Puncturing (Image credit: Intel) The wider 320Hz channels provided by Wi-Fi 7 allow more data to be transmitted if the access point and client are compliant. Wi-Fi 7 doubles the maximum available bandwidth to 320Hz (three channels) on the 6GHz band. Wi-Fi 6E offered a maximum of 160MHz of bandwidth. The result is higher efficiency, capacity and higher data transmission rates compared to Wi-Fi 6/6E. The increase from 1024 QAM to 4K QAM results in a 20 percent throughput increase. Wi-Fi 6E supports 1024 QAM, while Wi-Fi 7 increases that to 4K QAM. ![]() QAM, or Quadrature Amplitude Modulation, is a method by which data packets are translated to analog signals transmitted wirelessly. This lowers latency, significantly increases the data rate, improves load balancing across bands, and offers increased network reliability by duplicating packets across multiple links. (Just to add more confusion, 5 GHz bands are often labeled as “5G” out of the box, despite having nothing to do with your phone’s 5G network.Instead of connecting to a single 2.4GHz, 5GHz or 6GHz channel, as with Wi-Fi 6E, Wi-Fi 7 would allow a client to use all three bands simultaneously. Your router may automatically divvy up connections between these two bands, or it may display them as separate networks, letting you manually assign devices to each one. Today’s Wi-Fi 5 and Wi-Fi 6 routers offer two bands to minimize congestion, with the 2.4 GHz band offering slower speeds at longer range, and the 5 GHz band offering faster speeds at somewhat shorter range. Wi-Fi 6E is theoretically a big deal because it adds a new frequency band to home routers for the first time in more than a decade. (We’ve found, for instance, that TP-Link’s Archer AX50 Wi-Fi 6 router has better performance and range than the Archer A7 with Wi-Fi 5.) Still, Wi-Fi 6 alone doesn’t guarantee better reception, and its speed gains won’t be noticeable for most internet use cases. Granted, some Wi-Fi 6 routers benefit from additional features that aren’t directly related to the standard itself, such as better-designed antennas or more powerful processors. They support a stronger from of network security as well, but unless all your devices support Wi-Fi 6, you won’t reap the benefits of that extra protection. Router makers also claim that phones and laptops get better battery life while using Wi-Fi 6, though I’ve yet to see any independent tests that quantify this. ![]()
