Like perfect cellphone reception, wireless HDMI is a radio technology that’s long been promised and has shown little sign of materializing. But finally, it’s here. Gefen’s HDMI UWB Extender is not the first high-def A/V streamer to hit the US. (Sony’s Bravia Wireless Link has that distinction). But it’s the first that can fully replace an HDMI cable by offering up to 1080 progressive HD video.
Flat-panels were supposed to eliminate the hulking television cabinet. But they are tethered to boxes -- cable tuners, disc players, A/V receivers -- that fill a big piece of furniture. A wireless connection lets you at least stash those peripherals out of the way. We tried out the first two cable-free HD technologies: one that uses radio waves and another that piggybacks on your home's electrical wiring.
Our wireless manifest destiny is hampered by vaporware

Since long before the dawn of this century (always wanted to say that), tech pundits and proselytizers have been consulting their trusty prediction machines and proclaiming The Year of Wireless. It happened when IR ports showed up on laptops, then again when wireless mice began gracing desktops. Nearly everyone got on the bandwagon when Wi-Fi appeared, followed again with GPRS, EDGE, EVDO, etc—and of course with that most overpromised and underdelivered of technologies, Bluetooth.

It's a name only a government agency could love: the Future, Fast, Flexible, Fractionated, Free-Flying Spacecraft United by Information eXchange. Could DARPA possibly come up with a more tortured title for System F6?

When you´re tearing downhill on your snowboard, it´s a little distracting to take off your glove and dig out your iPod just to, say, hit pause. Instead, build this simple radio-frequency ID system and control your iPod by waving your hand in front of your coat.
A tag sewn into your glove sends instructions to a reader stashed in your pocket.

Surf the Web from the hammock out back (or the park down the block) with this solar-powered Wi-Fi extender

The promise of Wi-Fi is freedom-the ability to bring your laptop or PDA away from the anchor that is your desk and into your life. With most wireless routers, however, your life had better stop at around 300 feet, and forget about heading outside. Between the noise generated by other local wireless devices and physical obstacles like furniture and walls, chances are your Wi-Fi signal is little more than a whisper by the time it hits your backyard. So I built a box that can pick up that signal and boost it another 200 to 300 feet.

Forget AT&T and the like. The only phone company you need is Skype, which routes your calls over the Internet and, as of May 15, 2006, costs nothing for outgoing calls made by users in the U.S. and Canada. And now you can almost forget your cellphone provider too-with this new Voice over Internet Protocol (VoIP) gear, you can make calls using Skype (or Vonage, another VoIP provider) from just about anywhere.
The city hopes to jump-start recovery with the nation's first municipally-owned free Wi-Fi network

Doing business in the Big Easy just got easier. In an effort to make living and working in post-Katrina New Orleans as appealing as possible, the city is experimenting with an Internet network that is free for all users. The system-which uses wireless Internet routers mounted on streetlights to beam signals throughout the city-marks the first time that municipally-owned and -operated Wi-Fi has been offered to the public without restriction or cost.
