Listen up, kids: stay in school. Learn algebra. It may seem utterly useless, and 415.8 / x = 4.2 percent of the time, it is. But just wait until you're trying to play a game or stream a video over a terrible wireless connection, 'cause with the magic of algebra, you can boost your Wi-Fi speed by a factor of 10 or 20 or more.
Competition for the most interesting toaster is tight these days. They can look inexplicable — like a defibrillator. Or, they can entertain, like one that launches your toast onto your plate. We could go on, but instead here's a toaster concept that might actually do something useful: printing a disposable weather report on your morning slice.
Berlin, Germany — I'm not sure to ridicule this golf club head-looking gadget I found at the IFA electronics show or admire the utter devotion to its cause — keeping your plants not just alive but practically human.
Wi-Fi enabled asses you say? This is the type of news that doesn't phase us anymore. It's perfectly sensible that visitors to the Kfar Kedem (Village of Yore) theme park in Israel need Wi-Fi, so park owners attached routers to the back of five of the park's donkeys, offering a different take on the idea of "mobile Wi-Fi."
The Olympic organizers have made it pretty clear that they don't want you sucking up too much 3G bandwidth at the Olympic venues, but don't get the idea that you can sneak onto some stray Wi-Fi hotspot instead.
Even as ubiquitous as cellphones are, in many parts of the world, telephone booths still exist. In some places, newer telephone booths already come with Wi-Fi hotspots, but for old pay phones rotting away, like those in New York City, they're finally getting retrofitted with Internet access.
Want to know why your cell phone service sucks all the time? Phone companies will tell you: it's bandwidth, man. The wireless spectrum is getting crowded and there's just not enough room. What's needed is a new way to cram more data into the same amount of space, and the solution might be to twist multiple light beams together into a vortex.
Under normal circumstances, I wouldn't use this space to simply describe a new product, in this case two new products — the new Buffalo AirStation WZR-D1800H ($179.99) 802.11ac router and its sibling, the WLI-H4-D1300 wireless media bridge (also $179.99), which went on sale last week. But I'll make an exception for these two products, the first commercially available Wi-Fi 802.11ac gear. Aka "gigabit Wi-Fi," these and other pending 802.11ac gear promises to deliver Wi-Fi transmitted content at between 1.3 and 1.75 Gbps, around twice as fast as today's fastest 802.11n routers. Why the exception? Because these products portend a momentous change in our wireless communications lives. I'll explain this hyperbolic pronouncement — and what a "wireless media bridge" is — after the jump.
Do you have the need for speed? Wi-Fi speed? Who doesn't? Boy, do we have good news for you! A group of Japanese researchers have just broken the record for wireless data transmission in the terahertz band resulting in data transfers that are 20 times faster than standard Wi-Fi.
Trust me, all of your neighbors have already figured out that the password to your Wi-Fi network is the name of your cat, and they're busy pirating movies and software and when the MPAA breaks down the door you're the one who's going to a labor camp in Siberia. Don't let this happen to you, install wallpaper that keeps your Wi-Fi contained.
