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 to make it worth their while, carriers will gobble up those providers. According to Todd Myers, CEO of Airpath,Wi-Fi hotspots will benefit carriers by adding spectrum where cellular spectrum is running out, and by providing needed failover and backup capabilities. We've seen it with ISPs and ... (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?

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 3

In this concluding part of a three-part series on the space shuttle, WBT's David Geer looks at spread spectrum technology and its role in keeping encrypted data secure. The communications link to the orbiter is a spread spectrum link, a technology that was invented by Hedy Lamar (believe it or not!) during WWII for secure radio transmissions. Spread spectrum makes signal jamming and eavesdropping much more challenging, an important issue for a radio signal coming from orbit, which could be intercepted from anywhere within its footprint. Eavesdropping can also be used to interfer... (more)
