Home Wireless Wars Heat Up at Comdex

LAS VEGAS -- A wireless war is waging between competing networking standards--HomeRF and 802.11. And it may prove a barrier to widespread adoption of the networked home.

At Comdex here, backers of both 802.11 and HomeRF were out in force, with arguments as to why their own standard is better, and products to prove the point. Now that broadband Internet hookups and multiple PCs are invading millions of homes, the capability to share files and bandwidth--and soon broadcast movies and support telephone services--has become more attractive. Wireless networks hold the most appeal because they don't require cables and they afford mobility. But picking which standard will win may stump prospective consumers.

The 802.11 Challenge

On the face of it, HomeRF appears to have an uphill battle. First, its 1.6-megabits-per-second bandwidth is dwarfed by 802.11b's 11-mbps capacity. And second, 802.11b PC Cards for notebooks are already widely used in corporate settings, which is why the standard was adopted by the new Wayport service for high-speed wireless Internet access in hotels and airports. These corporate users are more likely to go for a home network that will let them use hardware they already have. Finally, 802.11 has an attractive-sounding upgrade path: a new version, 802.11a, will support 54-mbps bandwidth; the first products could appear by next summer.

Given these realities, it's not surprising that vendors such as IBM and Toshiba are preparing to ship notebooks with 802.11b capability built-in via a mini-PCI card. Nearly 70 companies, including IBM, 3Com, Nokia, and Lucent, have shown support for 802.11b by joining the Wireless Ethernet Compatibility Alliance (WECA); many of them had products on display at the WECA booth and elsewhere on the Comdex show floor. Umax spin-off MaxGate, for example, was one of several companies displaying an 802.11b-compliant gateway for sharing broadband access between computers and other devices.

Multimedia Friendly

Other vendors are looking ahead to refinements that will make 802.11 more suitable for streaming multimedia, which requires data to arrive in a more timely manner than 802.11b can guarantee in order to avoid stuttering and other artifacts. Netgear's new Wireless 11X line incorporates Whitecap technology, a proprietary protocol from ShareWave that was designed specifically for sharing multimedia between devices.

While existing 802.11b radios won't work on a Wireless 11X network, you can use a Wireless 11X adapter on an 802.11 network. Whitecap is expected to be incorporated into a future version of the 802.11 specification, 802.11e. Prices for Wireless 11X products will be on a par with today's 802.11b products: A starter kit with a gateway to enable Internet sharing and a PCI adapter will go for $299 when it ships in the first quarter of next year. A pair of PCI adapters for peer-to-peer networking will arrive in January, also for $299.
