Throw away your Ethernet cables* because MediaTek says Wi-Fi 7 will replace them

*Don't do this


MediaTek claims to have given the world's first live demo of Wi-Fi 7, and said that the upcoming wireless technology will be able to challenge wired Ethernet for high-bandwidth applications, once available.

The fabless Taiwanese chip firm said it is currently showcasing two Wi-Fi 7 demos to key customers and industry collaborators, in order to demonstrate the technology's super-fast speeds and low latency transmission.

Based on the IEEE 802.11be standard, the draft version of which was published last year, Wi-Fi 7 is expected to provide speeds several times faster than Wi-Fi 6 kit, offering connections of at least 30Gbps and possibly up to 40Gbps.

MediaTek boasts that this will make wireless connections a viable alternative to wired networks such as Ethernet even in applications that call for very high throughput, and predicts it will be used as the backbone of home, office and industrial networks.

"The rollout of Wi-Fi 7 will mark the first time that Wi-Fi can be a true wireline/Ethernet replacement for super high-bandwidth applications," said Alan Hsu, corporate vice president and general manager of MediaTek's Intelligent Connectivity business.

MediaTek claims that its Wi-Fi 7 Filogic technology will be able to achieve the maximum speed defined by IEEE 802.11be, and said that its demonstration shows off the multi-link operation (MLO) technology in operation.

MLO aggregates multiple channels on different frequency bands, allowing connections using 2.4GHz, 5GHz or 6GHz radios simultaneously. This is expected to deliver greater reliability, allowing data to flow seamlessly even if there is interference or congestion on some of the bands.

According to Cisco, another Wi-Fi 7 capability called Restricted Target Wake Time will enable an access point to reserve bandwidth for latency sensitive traffic, which together with MLO will provide network admins with the flexibility to optimise operations via a managed use of network resources.

Wi-Fi 7 will deliver faster speeds than Wi-Fi 6, even with the same number of antennas, according to MediaTek. This is because Wi-Fi 7 doubles the channel bandwidth to 320MHz and supports 4K QAM technology. Products with Wi-Fi 7 are expected to start appearing on the market in 2023.

Meanwhile, organisations have already been investing heavily in Wi-Fi 6, as The Register reported last year, as enterprises made Wi-Fi upgrades a priority in preparation for an expected return to the workplace by remote working employees. ®

    Two becomes one as ThinkPad P16 stands alone and HX replaces mobile Xeon

    Lenovo has halved its range of portable workstations.

    The Chinese PC giant this week announced the ThinkPad P16. The loved-by-some ThinkPad P15 and P17 are to be retired, The Register has confirmed.

    The P16 machine runs Intel 12th Gen HX CPUs, but only up to the i7 models – so maxes out at 14 cores and 4.8GHz clock speed. The laptop is certified to run Red Hat Enterprise Linux, and can ship with that, Ubuntu, and Windows 11 or 10. The latter is pre-installed as a downgrade right under Windows 11.

  • US won’t prosecute ‘good faith’ security researchers under CFAA
    Well, that clears things up? Maybe not.

    The US Justice Department has directed prosecutors not to charge "good-faith security researchers" with violating the Computer Fraud and Abuse Act (CFAA) if their reasons for hacking are ethical — things like bug hunting, responsible vulnerability disclosure, or above-board penetration testing.

    Good-faith, according to the policy [PDF], means using a computer "solely for purposes of good-faith testing, investigation, and/or correction of a security flaw or vulnerability."

    Additionally, this activity must be "carried out in a manner designed to avoid any harm to individuals or the public, and where the information derived from the activity is used primarily to promote the security or safety of the class of devices, machines, or online services to which the accessed computer belongs, or those who use such devices, machines, or online services."

  • Intel plans immersion lab to chill its power-hungry chips
    AI chips are sucking down 600W+ and the solution could be to drown them.

    Intel this week unveiled a $700 million sustainability initiative to try innovative liquid and immersion cooling technologies to the datacenter.

    The project will see Intel construct a 200,000-square-foot "mega lab" approximately 20 miles west of Portland at its Hillsboro campus, where the chipmaker will qualify, test, and demo its expansive — and power hungry — datacenter portfolio using a variety of cooling tech.

    Alongside the lab, the x86 giant unveiled an open reference design for immersion cooling systems for its chips that is being developed by Intel Taiwan. The chip giant is hoping to bring other Taiwanese manufacturers into the fold and it'll then be rolled out globally.
