Wireless priesthood begins blessing Wi-Fi 7 hardware

(2024/01/09)


CES Just in time for CES this year, the Wi-Fi Alliance has begun certifying hardware for Wi-Fi 7, the latest update to the global wireless networking specification.

Wi-Fi 7, the successor of Wi-Fi 6E, has been in the works for several years. The wireless protocol, known officially as 802.11be Extremely High Throughput, showed up in a research paper [1]in 2020 .

The latest standard doubles the available network bandwidth from 160MHz to 320MHz, which should allow compatible devices to communicate faster. It relies on the new 6GHz band, in [2]countries where that frequency is available, in addition to the 2.4 and 5GHz bands.

[3]

Using optimization techniques, the wireless spec can support a theoretical top speed of [4]more than 40Gbps , though vendors like Qualcomm suggest 5.8Gbps is a more realistic expectation. And chances are users will more typically see speeds [5]around half that figure .

[6]

[7]

Wi-Fi 7 boasts 4096 Quadrature Amplitude Modulation ( [8]QAM ), said to deliver 20 percent higher transmission rates than 1024 QAM because each symbol carries 12 bits instead of 10 bits of information.

It also supports Multi-Link Operation (MLO), which enables the simultaneous transmission and reception of data by using multiple links. The result, potentially, is better throughput and reliability, with lower latency.

[9]

Wi-Fi 7 also provides better support for deterministic latency, a way to ensure that network latency is predictable, which helps when using sensitive augmented/virtual reality applications or real-time industrial apps on the factory floor.

"The introduction of Wi-Fi CERTIFIED 7 marks the emergence of the latest generation of Wi-Fi and will be an accelerant to mass adoption of Wi-Fi 7," said Kevin Robinson, president and CEO, Wi-Fi Alliance, in [14]a statement .

"This certification underscores our relentless commitment to delivering cutting-edge technology that redefines the way users experience Wi-Fi, providing faster speeds, improved efficiency, and increased reliability which expand the horizons of what is possible through Wi-Fi."

The Wi-Fi Alliance will [15]certify that hardware bearing the Wi-Fi 7 logo works with the new specification. Those devices should start showing up later this year, or thereafter.

A handful of hardware vendors including Broadcom, CommScope RUCKUS Networks, Intel, MaxLinear, MediaTek, and Qualcomm piggybacked on the Wi-Fi Alliance announcement with canned statements celebrating Wi-Fi 7 and its purported possibilities. We'll spare you the details. Suffice to say, interested parties are excited and hope to sell more stuff.

[16]

Lumen Technologies last month [17]said it plans to show off its Wi-Fi 7-capable network device for Quantum Fiber customers at CES this week, with delivery slated for early 2024. And as we noted previously, UK networking vendor EE, now part of BT, is [18]working on Wi-Fi 7 kit of its own.

Apple is expected to add Wi-Fi 7, from a third-party chip, to its iPhone 16 Pro models later this year. The iBiz will reportedly switch to its own Wi-Fi 7 silicon when the iPhone 17 Pro line appears [19]in 2025 . ®

Thanks for this.

Sampler

I thought WiFi 7 was already certified with TP-Link selling the Deco BE85 (I was looking for a new WiFi mesh recently as my current is slower than my new fibre connection).

Re: Thanks for this.

Spazturtle

IEEE 802.11be is not yet ratified so none of these devices may end up working with the final version. Remember the Wi-Fi alliance is just a marketing organisation, they have no involvement in the actual specification.

40Gbps

Pascal Monett

5,8Gbps might indeed be more reasonable, especially when you take into account that the current data transfer maxes out at several hundred Mbps (which is not shabby at all, not by a long shot - I can watch TV now, when I had an ADSL line, it was almost impossible).

WiFi delivering >5Gbps means over 700MBps. That will be as good as my gigabit Ethernet. So, since we're talking WiFi and not mobile data, that means my Orange box connecting me to them thar intartubes will be upholding that speed and that means that I will be able to use it.

Good news overall.

Re: 40Gbps

Quando

Your Gigabit Ethernet will only ever get 120MBs (ish) max.

Using a WiFi 6 mesh I can already get 920mbs download from my ISP - mesh connects one floor of the house to the one with the ISP connection, with various wired links in the way. The big issue is that so little consumer level kit comes with anything better than 1 gigabit wired connections right now, so regardless of the internal WiFi connection the distribution to kit (desktops, NAS boxes, routers) is limited.

Re: 40Gbps

Sir Sham Cad

Absolutely what I was thinking re: end user kit, especially a large mix of equipment type, capability and age, at which point the users ask why the WiFi is "still shit" and "why have we spent all that money upgrading it?"

Which I'm waiting for sometime around Q3 FY24/25

If you would know the value of money, go try to borrow some.
