The Evolution of Wi-Fi 7 (IEEE 802.11be EHT) to Wi-Fi 8 (IEEE 802.11bn UHR)

When I posted about Wi-Fi 8 last year, I didn't realise that Wi-Fi was a popular topic on this blog and not only did it make it to the Top 5 posts, the previous post on Wi-Fi 7 made it too, even though it was posted back in the end of 2020.

The paper posted last year has undergone revision and a new version of 'What Will Wi-Fi 8 Be? A Primer on IEEE 802.11bn Ultra High Reliability' is available here. Quoting the abstract: 

What will Wi-Fi 8 be? Driven by the strict requirements of emerging applications, next-generation Wi-Fi is set to prioritize Ultra High Reliability (UHR) above all. In this paper, we explore the journey towards IEEE 802.11bn UHR, the amendment that will form the basis of Wi-Fi 8. We first present new use cases calling for further Wi-Fi evolution and associated standardization, certification, and spectrum allocation efforts. We then introduce a selection of the main disruptive features envisioned for Wi-Fi 8 and their associated research challenges, resulting from the outcome of the UHR Study Group. Among those, we focus on multi access point coordination and demonstrate that it could build upon 802.11be multi-link operation to make UHR a reality in Wi-Fi 8.

Here is a recent video from Giovanni Geraci, the author of the paper on What Will Wi-Fi 8 be?

While I am yet to move to Wi-Fi 6 on all my devices, I am hoping to see a lot more Wi-Fi 7 products in market this year.

Laser Inter-Satellite Links (LISLs) in a Starlink Constellation

When we first talked about Starlink back in 2019 , we saw in the video that the concept involved laser communication to communicate between the satellites. While the initially launched satellites did not have the laser communication mechanism built in, it looks like they are being added to the newer ones.  A report from Fast Company in late 2021 said: One of the next big upgrades in telecom will involve satellites firing lasers at each other—to beam data, not blow stuff up. The upside of replacing traditional radio-frequency communication with lasers, that encode data as pulses of light, can be much like that of deploying fiber-optic cable for terrestrial broadband: much faster speeds and much lower latency. “Laser links in orbit can reduce long-distance latency by as much as 50%, due to higher speed of light in vacuum & shorter path than undersea fiber,” SpaceX founder Elon Musk tweeted in July about the upgrade now beginning for that firm’s Starlink satellite constellation. ...

IEEE 802.11bn Ultra High Reliability (UHR), a.k.a. Wi-Fi 8

Back in 2020 we looked at the introductory post of Wi-Fi 7 which was followed up by a more detailed post in Feb 2022. We are now following on with an introductory post on the next generation Wi-Fi.  A new paper on arXiv explores the journey towards IEEE 802.11bn Ultra High Reliability (UHR), the amendment that will form the basis of Wi-Fi 8. Quoting selected items from the paper  below: After providing an overview of the nearly completed Wi-Fi 7 standard, we present new use cases calling for further Wi-Fi evolution. We also outline current standardization, certification, and spectrum allocation activities, sharing updates from the newly formed UHR Study Group. We then introduce the disruptive new features envisioned for Wi-Fi 8 and discuss the associated research challenges. Among those, we focus on access point coordination and demonstrate that it could build upon 802.11be multi-link operation to make Ultra High Reliability a reality in Wi-Fi 8. The IEEE 802.11bn UHR: Whose ...

China’s Growing Constellations, Ambitions and the Future of Satellite Broadband

China is increasingly asserting its presence in the low Earth orbit (LEO) satellite broadband arena, with two major constellation programmes, one state-backed and one commercially driven, now under active deployment. The government’s strategic plan for global communications infrastructure includes the Guowang network, targeting as many as 13,000 satellites, and the municipally supported Qianfan, also known as “Thousand Sails,” which aims for around 15,000 satellites. As of November 2025, Guowang has exceeded 100 satellites in orbit following a launch of nine satellites on 10 November. The Qianfan project, by contrast, has deployed around 90 satellites to date, a fraction of its target for regional coverage by the end of 2025. Both networks face significant challenges including manufacturing scale-up, launch cadence, orbital debris and regulatory timelines, yet their evolution has direct implications for the future architecture of global broadband, the integration of satellite and terre...
