...airplane flying at 100 knots and cars moving at 100 m.p.h. The geeks know this, and that's why they are working on the extension of the Wi-Max standard to incorporate mobility. In any case, our company has been promoting this technology as the basis for future 4G systems, and I believe this is a story that you may want to follow over the next couple of years.

...danger is that while the lab geeks are perfecting the handsets consumers will find other technologies that suit them just fine, allowing them to put off taking the plunge on 3G until a 4G comes along. John Moroney of Ovum, a consultancy specializing in telecoms, expects it could take five years before 3G becomes a serious consumer business. "There's already an existing good alternative: second generation voice plus sms text messaging," Moroney observes. Then there's so-called 2.5G, which transmits data in a similar fashion to UMTS, but with more limited bandwidth. The innovative Japanese operator...

Though they were not hit, the American pilots followed standing orders and answered in kind, dropping four cluster bombs on the firing battery. The fighters, three F-16s and one F-4G, then returned to Incirlik air base in Turkey...
...allied air base in the gulf area, for example, a specialized group of U.S. Air Force F-4G Wild Weasels continually land with film taken by nose- mounted cameras. Less than 10 minutes after a Weasel touches down, its film is rushed into one of a cluster of van-size steel boxes, bolted together at the edge of a runway, that serve as a photo intelligence center. Specialists wearing white gloves bend over light tables and peer through loupes to examine miles of black-and-white film as it rolls by. Most of the film is a dead gray wash...
...shooting war broke out, U.S. electronic-warfare planes such as the Air Force's F-4G "Wild Weasel" and the Navy's EA-6B would black out the radar and guidance systems of Iraqi air-defense missiles. "Command, control and communications are their Achilles' heel," says an Air Force officer. In this kind of combat, "they would have to do everything visually." Meanwhile, Saudi and U.S. AWACS planes would spot Iraqi aircraft as soon as they left their runways and direct F-15s and Navy F-14s to intercept them with Sidewinder and Sparrow missiles...
