Enlarge (credit: Alan Levine/Flickr ) There’s a new Wi-Fi standard in town, and it takes speed to another level. 802.11ad Wi-Fi is rated for data throughput up to 4,600Mbps, or four times faster than the current speed champ 802.11ac. That’s much faster than standard gigabit Ethernet and most home broadband speeds, although—as any Wi-Fi user knows—there’s a big difference between theoretical speed and what’s possible in practice. Still, want to stream high-bitrate 4K, HDR films over Wi-Fi? That won’t be a problem with 802.11ad. Even the best triple-layer UHD Blu-rays top out at 128Mbps bitrates. There’s even a chance it could make high-end wireless virtual reality headsets more practical. 802.11ad will at first be available via a new wave of home routers, a couple of which have already hit the shelves: the Netgear Nighthawk X10 and the TP-Link Talon AD7200 . As ever with brand-new tech, the routers demand a hefty premium, with the AD7200 costing an eye-watering £350/$360—that’s as much as even sophisticated mesh-based systems like the Ubiquiti Amplifi . Is 802.11ad Wi-Fi worth the cost? Is there anything you can even reasonably use it for right now? Or should you hold out for the inevitable price drops? Let’s find out. How does 802.11ad Wi-Fi work? Like previous versions of Wi-Fi, 802.11ad is an official standard ratified by the Wi-Fi Alliance. Unlike previous versions, however, the tech behind it didn’t come from the IEEE (Institute of Electrical and Electronics Engineers). Instead, it’s based on tech created by the WiGig (Wireless Gigabit) Alliance, which was officially announced back in 2009, entered draft stage with the IEEE in 2011, and finally emerged as the standard it is today when the WiGig Alliance merged with Wi-Fi Alliance in 2013.

4.6Gbps Wi-Fi: How 60GHz wireless works—and should you use it?
New submitter mirandakatz writes: Since India’s prime minister banned 86 percent of the rupee notes in circulation last month, citizens have been waiting in hours-long lines for ATMs. But these circumstances have also created an unexpected progression: a burgeoning cashless economy. At Backchannel, Lauren Razavi explores how India is now beating many Western countries in adopting mobile payments, and how demonetization has triggered a radical shift toward reimagining India’s enormous informal economy as a data-driven digital marketplace. From the report: “Before last month, Paytm, a mobile app that allows users to pay for everything from pizza to utility bills, saw steady business — it was processing between 2.5 and 3 million transactions a day. Now, usage of the app has close to doubled. 6 million transactions a day is common; 5 million is considered a bad day. Rather than being forced to idle away time in excruciatingly long lines, ‘people are proactively exploring other ways to settle payments besides cash, ‘ says Deepak Abbot, senior vice president at Paytm. ‘Now people are realizing they don’t need to really line up, because merchants are starting to accept other forms of payment.’ All of this has created a newfound system that practically incentives mobile payment. With so many people queuing up at banks every day — and a lot of Indian bureaucracy to wade through in order to open a traditional bank account or line of credit — the appeal of more convenient digital alternatives is easy to understand. According to a report in the Hindu Business Line, as many as 233 million unbanked people in India are skipping plastic and moving straight to digital transactions. ‘Cash has lost its credibility and payments are no longer perceived in the same way, ‘ says Upasana Taku, the cofounder of Indian mobile wallet company MobiKwik, which reported a 40 percent increase in downloads and a 7, 000 percent increase in bank transfers since demonetization. ‘There’s chaos at the moment but also relief that India will now be an improved economy, ‘ she says.” Read more of this story at Slashdot.
