Using the 2.4 GHz and 5 GHz (or 6 GHz for Wi-Fi 6e devices) bands simultaneously, latency issues, which can impact how fast and responsive an online game acts and feels, can be eliminated, effectively using two Wi-Fi connections at once, and switching between the two.
Because Wi-Fi used to introduce latency, PC gamers who required a fast and reliable internet connection would stick with using an Ethernet cable instead. However, this new technology should mean gaming via Wi-Fi is much better.
According to Qualcomm, in its tests, it found that the Wi-Fi Dual Station with Qualcomm 4-stream DBS technology to give it its full name, “consistently delivered sustained jitter free wireless gameplay similar to Ethernet latency under the same conditions,” and in certain cases lowered latency by up to four times.
Qualcomm’s Wi-Fi hardware, including FastConnect, appears in a huge range of products, including laptops from big names such as Acer and Lenovo. New Windows 11 laptops from these manufacturers should benefit from this new Wi-Fi tech. James Lin, General Manager, Notebooks, IT Products Business, Acer Inc, explained that “Acer’s new gaming notebooks that feature FastConnect 6900 connectivity will provide Ethernet-grade Wi-Fi” – a bold claim indeed.
This tech isn’t just for gaming, as any task that requires a lot of two-way traffic, such as video calls and remote management, could benefit from this.
Ian LeGrow, vice president, program management for Windows platforms and services at Microsoft, also stated that “Microsoft is pleased to bring ‘Wi-Fi Dual Station’ to the Windows 11 ecosystem, enabling our Windows OEMs and ecosystem leaders to deliver low-latency performance on the latest Wi-Fi hardware. Games and other latency-sensitive applications can now leverage two concurrent Wi-Fi connections providing best-in-class user experiences.”
While Qualcomm and Microsoft worked closely to bring this new Wi-Fi tech to Windows 11, one of the most interesting aspects of the announcement was the involvement of Valve, the company behind the popular Steam games store (and upcoming Steam Deck handheld), as well as iconic games like Half-Life.
According to the announcement, Valve has added support for Wi-Fi Dual Station to the Steamworks SDK, so games such as Dota 2 and Counter-Strike: Global Offensive (CS:GO) will have built-in support, and when played on a laptop or PC with Windows 11 and Qualcomm FastConnect hardware, these games should run even better when online.
The collaboration with Valve could also mean this feature comes to the Steam Deck console, which begins shipping in December, 2021. As a handheld console, it will rely on Wi-Fi for multiplayer games, so improved latency will definitely be a plus, and could be a big deciding factor for Valve.
However, out of the box, the Steam Deck doesn’t run Windows 11, but the Linux-based Steam OS. This could point to future support for Linux and other operating systems, alongside Windows 11.
Analysis: Another great reason to upgrade to Windows 11
This new Wi-Fi technology from Qualcomm certainly promises a lot. The idea of playing competitive online games via a Wi-Fi network is often scoffed at by serious players, due to the latency and reliability issues that Wi-Fi introduces. Any lag or delay can mean the difference between winning or losing an important match.
This is why most gamers prefer a wired Ethernet connection – but that’s not always possible unless you want to trail cables all over your house.
If the Wi-Fi Dual Station technology can deliver on combining Ethernet-like latency with the convenience and flexibility of Wi-Fi, then this is another great reason to upgrade to Windows 11. If you want more reasons, check out our Windows 11 review.
