2Wire's new products aim to extend Wi-Fi deeper in the home. The combined DSL/Wi-Fi modem uses 400 milliwatts of power, far more than most Wi-Fi access points, and uses three antennas. These upgrades, 2Wire claims, extend coverage in a wider footprint. SBC and BellSouth both sell modems from 2Wire.
2Wire calls the radio 802.11b and the release doesn't mention that customers can only use a compatible 2Wire card, so it sounds like this complies with standards.
The release should be available here at some point.
