Today, computers go everywhere with us. We port laptops, handhelds, and BlackBerry devices for every purpose from remote teleworking to anytime, anywhere e-mailing. As long as the device does its job, we don't gripe. The question is no longer whether we'll be taking computers everywhere; it's whether the ones we take will be smaller and more comfortable, convenient, attractive, and even seamlessly wearable. Imagine that your job requires you to keep your hands and eyes free. You have no access to a computer, whether you're a utility worker or a package handler. Now imagine doubling your efficiency by having access to a full-blown, hands-free PC that sits almost weightlessly on your person? Suppose you find yourself in a career that is getting more technical all the time. Stopping to read a tech manual is going to slow you down. What if wearable computers made it pos... (more)

The End of Telecom As We Know It?

Most rainbows are colorful shining heralds that a storm has passed. "Project Rainbow" leaves us in a fog as to what is to come. So do frequently named participants such as IBM, Intel, AT&T, and Verizon by their silence. At its vaguest, Project Rainbow is a consortium that loosely ties at least the aforementioned companies together. According to a consensus of surrounding industry hearsayers, the purpose is a serious verbal rumination about the plausibility of a nationwide 802.11 network that all participants could profit from. The fact that Project Rainbow exists with such certai... (more)

Space Shuttle Wireless Part 2

In a continuing report on the space shuttle and the critical role that wireless technology plays in its launch, orbit, and re-entry, WBT's David Geer takes a closer look this month at the program's S-band and Ku-band systems. In last month's article about NASA's Space Shuttle, I introduced the shuttle program's S-band system, the wireless frequency used at those points in the mission when the shuttle's payload bay doors can't be opened to release the Ku-band antenna. The S-band is the range of RF spectrum from 1,700-2,300MHz. The NASA S-band system uses S-band PM (phase modulati... (more)

The 7 Biggest Wireless Surprises Coming in 2004

Wireless is taking off in a big way, but some surprises await us. How do you predict the seven biggest surprises about to hit the wireless industry? I spoke with two well-connected "ringers" who have a keen sense of the industry. I absorbed their combined input and pooled seven responses. My Ringers Alex Lightman is a wireless visionary heavily involved in supporting IPv6. He keeps his wearable computer from Charmed Technology (his product, his company) focused on the pulse and frequency of tomorrow's wireless realities. Attorney Robert Rini is a telecommunications and technology pa... (more)

Cellular Voice and Voice over Wi-Fi

Alliances, competitors, technologies, hardware, and roaming line the path to dual-mode, cellular/Wi-Fi handsets. Another game of sit and wait has begun as major carriers ready themselves to swallow small providers whole once they have fattened themselves with successful Wi-Fi hotspots. Which end of this communications food chain are you on? Free spectrum is a good motive for providers to get into Voice over Wi-Fi. Providers will leverage the spectrum for voice as they do for data while they continue to build out their hotspots. When there is enough coverage by provider hotspots ... (more)
