Trev, I don't think the AT&T people are good at arithmetic [or math]. <..."I feel 802.11 still has a long way to go to meet the needs of the mobile professional," Amin said. "As for costs, it's true 802.11 capital expense is very low, but you also have to look at the operational expense."

For example, Amin said that AT&T's 3G network could deliver wireless data to a two mile radius in and around the Seattle-Tacoma airport using a single macrocell costing about $2 million and a few T1 lines costing about $1,500. "I challenge you to do the math for 802.11, and you still won't have as wide a coverage radius," Amin said....contd... >

There are various articles recently published which I can say are written in ignorance and the articles have been written by people who one would expect to be well-informed. Conventional wisdom about 80211.b and its use in mobile networks seems about as accurate as the Stanford professor who thought CDMA breaches the laws of physics.

You can see the Wireless Data Forum presentation from RoamAD which piqued my interest here: wirelessdataforum.org.nz Scroll down to the last item or click here to go directly: wirelessdataforum.org.nz

A single macrocell would have shadows everywhere. If that's the best and cheapest the AT&T guy can come up with, I think he's on a losing wicket.
