Quantenna's new chip turns 802.11ac Wi-Fi up a notch

There's more to 802.11ac than we've seen so far.

Quantenna Communications announced today the first 802.11ac chipset, called QSR1000, with a ceiling speed of up to 1.7Gbps, which is 400Mbps faster than the current cap of any 802.11ac router, such as the Asus RT-AC66U or the Trendnet TEW-812DRU.

The QSR1000 achieves this new speed by supporting the new 4x4 MU-MIMO 802.11ac standard. In other words, it's the first quad-stream Wi-Fi chipset. Up to now, all existing Wi-Fi devices have only used a single-stream, dual-stream, or three-stream setup. (Read more about Wi-Fi standards here.) … Read more

Findables case turns your entire smartphone into a business card

QR codes haven't exactly set the world on fire, yet most people know what they are, and most phones can scan them, either out of the box or with a third-party app.

The Findables Case takes that idea to heart by emblazoning a unique QR code on each hard-plastic shell, the idea being to use that code to share information about yourself or help recover your lost phone.

In other words, your case can now take the place of your business card, while at the same time offering good Samaritans a means of contacting you (that doesn't involve poring through your address book).

When someone scans the code, they'll see one of three profiles (chosen by you via a companion app or the Findables Web site): Business, Social, or Lost.… Read more

Facebook kills social suicide app Social Roulette

A Facebook app that mimicked the real-life lethal game of Russian roulette in deleting user accounts apparently did not leave the social network fired up.

Social Roulette, which launched Saturday, gave players a one-in-six chance of deleting their own Facebook account, a form of social suicide, if you will. If you lost (or won, depending on your level of exasperation with social networking), the app would delete all aspects of the user's account, including posts, likes, photos, and friend connections, before deactivating the account.

According to its description, the app was intended for people looking to burn their Facebook … Read more

Home networking Part 7: Power line connections explained

Editors' note: This post is part of an ongoing series. For the other parts, check out the related stories section below.

Power line networking basically turns a building's existing electrical wiring -- the wires that carry electricity to different outlets in the house -- into network cables, meaning they also carry data signals for a computer network. And this means virtually all households, in the U.S at least, are "wired for" power line networking. It doesn't replace a regular network, so you'll still need a router, but it's a good way to extend … Read more
