next year. It increases data throughput to 54Mbps (from today's 11Mbps) and moves to the less congested 5-GHz radio band. That could make it popular in homes that are cluttered with interfering cordless phones and baby monitors.

802.11b (Wi-Fi) Backers: 3Com, Apple, Cisco, Intel, Nortel
The current wireless network leader. Operates on the 2.4-GHz frequency and shuttles data at speeds up to 11Mbps. Despite interference and security issues, its affordability and heavyweight backers have made it the standard to beat. 802.11g Backers: 3Com, Apple, Cisco, Intel, Nortel
An extension to 802.11b, it moves data at speeds of at least 20Mbps and perhaps as high as 54Mbps. Available at the end of 2002, it's likely to be the corporate choice, since it is compatible with existing 802.11b products. Still needs FCC's blessing. 802.11e Backers: ATT, Cisco, Intel
Improves streaming-media performance for every flavor of 802.11. When it rolls out at the end of next year, it will bring great functionality to 802.11, but much later than HomeRF 2.0. No FCC approval yet. HomeRF Backers: Compaq, Motorola, National Semiconductor, Proxim, Siemens
The current alternative to 802.11b. Also operates on the 2.4-GHz spectrum, but data moves at a poky 1.6Mbps. Less prone to interference than 802.11b, but it has been hurt by decreasing prices for 802.11b products and Intel's defection. HomeRF 2.0 Backers: Compaq, Motorola, National Semiconductor, Proxim, Siemens
Boosts to 10Mbps, but stays on the 2.4-GHz band, ensuring compatibility with existing HomeRF devices. Slower than 802.11, but voice and multimedia support could win consumers when it hits this year. HyperLan2 Backers: Ericsson, Lucent, Xilink
The emerging European standard, it operates on the 5-GHz band and boasts a 54Mbps data speed. Likely to be the Old World's choice for the short term. By Alexei Oreskovic
