Hasta La Gadget!

Some internet purveyors make a big fuss over having public WiFi. It’s not often that they go out of their way to help you find that WiFi, however, and that’s where CableVision’s recently posted (but just now official) Optimum WiFi Hotspot Finder comes in. If you’re one of the cable company’s Optimum Online subscribers, the currently iOS-only app will pinpoint the 35,000 access points that you can call a home away from home. As we’d hope, the app both finds hotspots nearby for an immediate fix or drills down to specific hotspots if you’re just that determined to find a restaurant with a data pipe. The app and WiFi access are both free — apart from that small matter of the cable account, of course — and will no doubt help iPad and iPhone owners for whom Optimum WiFi’s 15Mbps speed is an oasis in a sea of pokey 3G.

Stoked about the gigabit speeds your new 802.11ac WiFi router is pumping out? One group of scientists hailing from NASA’s Jet Propulsion Laboratory and universities in the US, Israel and China isn’t so impressed, having generated a wireless signal clocking in at 2.56Tbps. Proof of the feat was published in Nature Photonics, which details their use of orbital angular momentum (OAM) to make the magic happen. Current wireless protocols alter the spin angular momentum (SAM) of radio waves to hold info, and by combining both methods the team was able to pack eight data steams into a single signal, resulting in the mouth-watering number noted above. The best part is, applying different levels of OAM twist to SAM-based transmissions theoretically allows an infinite number of streams per signal, meaning seriously increased bandwidth without the need for additional frequency. So far the wireless tests have only been conducted over a measly 1m, but the scientists reckon it’ll work at distances up to 1km and that the concept could also be used to boost speeds in existing fiber-optic cables. As with many scientific advances, it’s unlikely hardware capable of such speeds will be available any time soon, so 802.11ac will have to suffice… for now.
