No longer do people request information from machines, now they're all talking to each other! M2M technologies and applications span the supply chain. At near individual item level, RFID tags and sensors automate data communications about pallets and cases. Like bar codes, the devices are ID'ed and tracked, and with them the goods and inventory. For this tracking, the devices need a path to communicate through. Communications infrastructure includes cellular (CDMA, GSM), and value-added networks like Sterling (www.sterlingcommerce.com). Finally, RFID tags and sensors talk to computers that process and interpret collected data so that those computers, or an individual, can make decisions about managing the supply chain (placing orders). Vendor-Managed Inventory Vendor-Managed Inventory (VMI) uses "pallet level technologies to track sales and inventory on a daily bas... (more)

Is Worldwide Wireless Broadband Barreling Our Way?

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 bandwid... (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 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)

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)
