Network It Out

Tomorrow's wireless communications will be more important than ever. Good thing our networks will be able to keep up.

4G or Not 4G?

Poor AT&T. Just as it’s getting the hang of supporting the iPhone on its 3G network, 4G networks will begin popping up from Sprint this year and from archrival Verizon in 2011. What does that mean for us, besides catty PR fights among the carriers? A blazing fast mobile internet with enough bandwidth for HD movies, video chats, and--we hope--fewer dropped calls.

Like 3G wireless networks, 4G isn’t a single new technology. It’s a blanket term for a range of technologies and specifications that add up to the same thing: speed. Current 3G offers downloads of roughly 1.4Mbps. Compare that to 4G’s promised bandwidth of at least 100Mbps, and you’ll see what the fuss is about. 4G works its magic in part by using MIMO (Multiple In Multiple Out) technology to broadcast using several antennas simultaneously on multiple frequencies.

4G’s strengths make its eventual adoption by Apple a no-brainer, no matter which carrier has the iPhone next year. Apple is serious about establishing the iPad as a mobile media device, and it’ll want a big pipe to carry movies and music to cellular customers. That’s just what 4G provides. As for the iPhone, who knows? Steve may decide to stick with AT&T and its 4G network expected to roll out alongside Verizon’s in 2011.

Crank Up the 802.11AC

Closer to home, we’ll use 802.11n Wi-Fi, but at faster speeds than we’ve seen before. Apple has sold 802.11n devices since 2007, but the protocol’s final standard was only approved in 2009. Happily, that means the business of making Wi-Fi as fast as possible can begin in earnest. Like 4G, 802.11n uses MIMO to improve performance, but manufacturers couldn’t take full advantage of the technology before the protocol was complete. Now that it is, devices can officially support maximum speeds between 400 and 600Mbps…if your hardware has the antennas to deliver the boost. Expect that hardware to start arriving in stores later this year.

But the Mac life is never a simple march of progress, and there’s always something new on the horizon. Sweet! Work drafting the next Wi-Fi protocol, 802.11ac, has already begun. Devices supporting the new standard aren’t expected until 2012 at the earliest, but they’ll boast speeds of up to 1Gbps when they’re available. At press time, Ethernet’s agent was unavailable for comment.

More Power to You

Apple is going power mad. Its future devices will charge up almost anywhere.

Powered by the Sun

Solar power is overdue for a makeover, and if anyone can do it, it’s Apple. In 2008, it applied for a patent to slip solar cells beneath a device’s LCD screen, and early this year, it applied for another patent to cover portable devices with solar collectors.

Solar-powered MacBooks? Yes please!
 
Wilder still, a March 2010 patent describes a MacBook with a solar panel that folds to collect sunlight or even to illuminate the LCD screen without drawing power from the battery. We’re still waiting for these designs to see the light of day--ha!--but it’s clear someone at Apple has spent a lot of time looking at the sun.

Go Wireless

Besides flying cars, wireless electricity is the ultimate in futuristic convenience. Today’s charging mats come close, but the magnetic induction they use keeps devices tethered to one spot. That’s why we hope Apple adopts WiTricity’s technology for truly wireless power up to several feet away from the base station. The science involved would baffle the DHARMA Initiative, but it involves something called sharply resonant strong coupling to generate an oscillating magnetic field that’s captured and converted to electricity by a sensor in your device. Or it will, anyway, when WiTricity-powered gear reaches stores sometime in the future.

Wireless power? As in, electricity beamed through the air? Shocking.

Your Valuable Input

No matter how cool Apple’s upcoming products are, they’ll only be as good as what we can do with them. Here’s how we’ll interact with the future.

Touchier Mice

The mouse has plenty of life left, at least according to Microsoft. It’s produced some stellar mice over the years, but Redmond’s recent Multi Touch prototypes could be the best yet. The FTIR (Frustrated Total Internal Reflection) Mouse’s high-res camera tracks finger gestures through a curved piece of clear acrylic so you can scroll, swipe, and pinch around on the acrylic in order to manipulate onscreen objects. The Orb Mouse works on much the same principle, but offers a whole hemisphere to interact with in your hand.

The shrunken Side Mouse looks more like a wrist rest than a traditional rodent--its tiny camera tracks your fingers as they move across your desk or whatever surface you happen to be working on. Best of all, these mice incorporate the Multi Touch equivalent of keyboard shortcuts to perform zooms and other common commands quickly. Cupertino, start your copiers!

Microsoft's FTIR Mouse makes magic out of a high-res camera and a piece of acrylic that together create Multi Touch-style input.

But the coolest input technology on the horizon for Apple’s gear lies in--big surprise--touchscreens. Future Multi Touch devices will sport haptic feedback, or the sort of physical response you’ve gotten for years from vibrating gamepads and cell phones, to help make input feel more natural. In 2011, Artificial Muscle is bringing to market its EPAM (Electroactive Polymer Artificial Muscle) technology, which tenses and relaxes touchscreens in response to input. That sounds pretty fascinating all by its lonesome, but Apple’s recent patent applications show it has something more subtle in mind--a layer inside the touchscreen that delivers vibrating feedback localized to specific onscreen buttons and switches. That level of fine-tuned feedback would make typing on the iPad’s large screen even more satisfying and could pave the way for MacBooks without physical keyboards.
