omdex Fall 2000 was a wireless world as major PC companies introduced products that take advantage of emerging standards for untethered data transmission.Hewlett-Packard last week introduced Omnibook 500, which features expansion cards that give users mobile connectivity via the 802.11b and Bluetooth wireless protocols. The 802.11b protocol is designed to support wireless network access, while Bluetooth aims to replace cables that connect PCs to printers and other peripherals.
Infrared technology was once touted as a means to the latter function, but infrared beams must be aimed at the target device and that "could get clumsy," says Jean Luc Meyer, worldwide marketing manager for HP's PC group. Bluetooth uses omnidirectional radio waves. In the coming months, HP says it will build wireless compatibility directly into the Omnibook 500.
Compaq officials at Comdex said the company will unveil a version of its m300 notebook with a Multiport module early next year. Built into the back of the monitor, the module has an antenna and supports Bluetooth and 802.11b. "We wanted something that wouldn't use up the PCI or mini-PCI slot," says Jeff Groudan, marketing director for Compaq's portable PC division.
Although last year's Comdex also featured a bevy of wireless products, observers say this year's crop could have greater impact. Because prices are down, "there's no reason companies won't give these products a long look because they won't have to pay a premium," says Technology Business Research analyst Brooks Gray. Also, the 802.11b protocol boosts transmission rates to 11 Mbps, up from the 2 Mbps offered by its 802.11 predecessor.
Still, obstacles must be overcome. Most significantly, 802.11b and Bluetooth should complement each other. But using them simultaneously can degrade performance because they use the same radio frequency.
Dell Computer CEO Michael Dell, whose company introduced a wireless-ready notebook before Comdex, says he expects most users will give precedence to 802.11b. "There's value in Bluetooth," Dell says, "but 802.11[b] is much more valuable because it gives you a dependable network connection whether you're home, in an office, or in an airport lounge."
