Wifi 7 Release Date, Standard, Speed and Wifi 7 Routers

Let’s find out Wifi 7? Wifi 7 release date, standards, Wifi 7 routers, and Wifi 7 speed etc.

What is Wifi 7

The folks at IEEE and Wi-Fi Alliance aren’t sitting still. After just launching Wifi 6, which is (802.11ax) extended into the ‘6GHz band’ (5.71 – 7.13GHz actual), engineers are already knee-deep in 802.11 be development, which is likely to adopt the Wi-Fi 7 name. Called ‘Extremely High Throughput’(EHT), it features impressive headline Wifi 7 speeds of 30Gbps.

However, the better features, in my opinion, are some of the improvements elsewhere. Firstly, though, don’t worry if you’ve just upgraded wifi 6 routers vs wifi 7 routers for home, as this new standard isn’t expected to launch for a few years yet.

Wifi 7 Standards

Just as Wi-Fi 5 (802.11ac) and Wi-Fi 6 borrowed heavily from 4G LTE mobile tech, such as MU-MIMO and OFDMA respectively, Wi-Fi 7 is borrowing from tech that’s now being proven in 5G.

That’s clever, because it means research and development costs are being adsorbed by smartphone chip/modem makers and mobile network operators, with engineers being able to reuse their knowledge when it comes to creating future Wi-Fi chips.

However, even though Wi-Fi is influenced by mobile tech,these two areas are also competing against each other in some respects. 5G has enjoyed taking a lot of wireless spectrum under its paid-for banner, which locks it out from public use.

Mobile lobbyists are also pushing to use the same 6GHz spectrum that’s in the process of being allocated in the US, UK, and Europe. Wi-Fi 6E effectively beat them to it, though. By launching products into the market that use the full 5.71–7.13GHz range, Wi-Fi 6 has made a spectrum land grab that can’t be undone.

Wi-Fi 7 builds on this approach by allowing each compatible device to aggregate multiple smaller bands among the 2.4GHz, 5GHz, and 6GHz ranges, boosting performance. Termed ‘noncontiguous uplink’ it’s analogous to the carrier aggregation system used in 4G and 5G, and it will really help to increase average throughput for upload heavy tasks, such as streaming.

Why it’s not also being used for down-link is unclear, although it’s possible that non-contiguous down-link could be added later during the standard’s development. Mesh networks will get a big boost from non-contiguous connections, while also benefiting from ‘Multi-Access Point (AP) Coordination’ and ‘Cooperative Multi-User MIMO’ (CMUMIMO).

These technologies mean that data isn’t just split between various bands across the 2.4GHz, 5GHz, and 6GHz frequency ranges, but also across different access points. Working together, these three technologies will make large mesh networks feel seamless.

That’s not just great for the home, but in particular, it will result in a significant boost for public Wi-Fi spaces that are shared by many users. Beyond these new additions, Wi-Fi 7 also multiplies the core numbers of Wi-Fi 6.

It doubles total channel bandwidth from 160MHz to 320MHz, doubles the number of MIMO streams from 8 to 16, and quadruples the data squeezed into the signal with 4096-QAM.

This all sounds great, but the downside will be increased cost. Even with some of the principal research and development costs offloaded, all this tech needs really high-performance network processors, plus twice the number of antennas and all their associated radio front-end filter chips, which increases costs.

Backward compatibility means Wi-Fi will remain ubiquitous to all devices, but the best speeds and most reliable connections won’t come cheap. A main benefit of Wi-Fi is that it’s accessible in places where you can’t get a mobile signal – let’s hope the 802.11be development committee doesn’t forget this.
