“Qualcomm is launching a family of chips that can add incredibly high-speed Wi-Fi — at speeds up to 10 gigabits per second — to phones, laptops, routers, and so on,” reports The Verge. The Wi-Fi standard used for something like replacing a virtual reality headset’s data cable with a high-speed wireless link is being updated. Qualcomm’s latest chips improve a wireless technology called WiGig, which relies on a connection standard known as 802.11ad, which can hit speeds up to 5 gigabits per second over close to 10 meters. The new generation of that wireless standard, called 802.11ay, can reach speeds twice as fast, and can do so up to 100 meters away, according to Dino Bekis, the head of Qualcomm’s mobile and compute connectivity group. The Wi-Fi Alliance says the new standard “increases the peak data rates of WiGig and improves spectrum efficiency and reduces latency.” From the report: So why not just use this as normal Wi-Fi, given how fast it gets? Because that range is only line-of-sight — when there’s literally nothing in the way between the transmitter and the receiver. This high-speed Wi-Fi is based on millimeter wave radio waves in the 60GHz range. That means it’s really fast, but also that it has a very difficult time penetrating obstacles, like a wall. That’s a problem if you want a general purpose wireless technology. That’s why 802.11ay, like 802.11ad before it, is being used as an optional add-on to existing Wi-Fi technology. If you’re one of the people who has a need for these extreme wireless speeds, then maybe you’ll find a use for it. Just keep in mind, you’ll probably need to keep your router and the device receiving these high speeds in the same room in order for it to work, due to the whole “walls” issue. WiGig will also be competing with 5G, as it offers “similarly fast speeds over similarly limited distances,” reports The Verge. “[T]he two standards may be competing as an option for delivering internet from a tower to a home — that’s what Facebook’s Terragraph is doing with WiGig, and it’s what Verizon is doing with 5G.”
