For the first time, multi-vendor tests of WiFi 7 – on Intel and Broadcom equipment – reach a major milestone with speeds above 5 Gbps

Intel announced that a test using an Intel-based laptop and a Broadcom-based WiFi 7 access point broke the 5Gb/s mark for the first time, hitting a major milestone in the development of WiFi 7. This industry first demonstration of how WiFi 7 works cross-vendor is essential, as the standard is intended to cover equipment produced by thousands of different vendors, and all must work together seamlessly. WiFi 7, also known as 802.11be, introduces many features to the venerable WiFi standard. In particular, the 6 GHz spectrum allows the use of much wider channels, up to 320 MHz, to take advantage of considerably higher throughput and multilink, and to make much more efficient use of the available spectrum, not to mention modulation of 4K QAM (quadrature amplitude modulation) data.

Multilink and high throughput

While larger channels and modulation functions are important, the real novelty of WiFi 7 lies in multilink, ie the use of two separate channels simultaneously for individual connections in two different modes. Either in alternate multiple link: in this case, one channel is used for uploading and the other for downloading, which makes it possible to obtain a much higher speed connection than a standard single link. Either in simultaneous multilink: in this case, two channels can send data up and down at the same time, which increases frequency flexibility and reduces latency. According to Intel, WiFi 7 will become the platform for wireless experiences for the next 10 years, due in part to its faster speeds and lower latency. These features could not only improve WiFi experiences, but also open up a whole new class of applications, including augmented reality (AR), highly responsive gaming, streaming media with up to 16K resolution, while supporting supports many more devices per access point than the current WiFi generation.

According to Phil Solis, research director at IDC, the results from Intel and Broadcom pave the way for testing new products to further develop WiFi 7. WiFi 7 is the most powerful and capable WiFi protocol to date. and will enable WiFi to continue to serve the most demanding applications in consumer and vertical markets with the highest level of purposefulness to date, it said in an Intel statement. The final date for the official WiFi 7 standard is scheduled for mid-2024, but some experts believe that equipment supporting a pre-standard could be on the market from 2023, given the speed at which enterprises have adopted the WiFi 6 standard. , the pace of adoption of the WiFi 7 standard could be quite rapid.
