From the New York Times: Etherlinx, a company based (of course) in a Silicon Valley garage, is developing a modified 802.11 for connecting the ‘last mile’ to homes. Or, in their case, up to the last 20 miles. Their box goes on the wall of the house and has two radio cards: one talking to their base stations and one doing WiFi into the home.
And from MacCentral:
IBM is rolling out large amounts of 802.11 on corporate campuses and is investigating the idea of national networks. It’ll be interesting if they ever get further than talking about it.
