Worldwide wireless broadband connectivity is spreading around the globe. What technologies are taking us there? How close are we? What are the obstacles? Robert Hoskins, director of the Broadband Wireless Alliance (BWA), describes three network environments that help define the three available wireless connectivity types. "Think about it more as PANs, LANs, and WANs," he says, "Personal Area Networks, Local Area Networks, and Wide Area Networks. All of these can be either fixed or mobile networks. You sacrifice bandwidth for mobility." Hoskins detailed his view of wireless bandwidth and connectivity with the following examples. An uncompressed phone call takes up 64Kbps of bandwidth. With digital compression, a voice phone call takes up 8Kbps of bandwidth. A real broadband connection should deliver at least 1Mbps. Today's fastest mobile network, Ricochet, which is no... (more)

Tauzin-Dingell and the Baby Bells Sing 'You and Me Against the CLEC World!'

You don't hear much about the Tauzin-Dingell Telecom Bill, unless you're in Washington, DC, or in the camp of either the CLECs (Competitive Local Exchange Carriers) who oppose it or the ILECs (Incumbent Local Exchange Carriers) who we might assume all but wrote it. But Tauzin-Dingell (now in the Senate) would allow the Baby Bells to keep their legacy networks and any of their new broadband infrastructure developments to themselves. It would gut the Telecom Reform Act (TRA) of 1996. It could raise prices on all telecom services; it could be the end of some CLECs. The Tauzin-Dingel... (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)

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)
