Martin,

A cell with radius of 2 mile would cover about 12 sq. mile. (pi*r^2) right?

Hey, it must have been late at night... Of course you are right, it's about 12 miles, not 6 miles. I've corrected it above. The ratio between Access Points and base stations gets even more unfavourable.
Thanks, Martin

Martin,

Two miles might be being a bit optimistic for cellular in an urban environment. Depending on the design target you're probably looking at about one mile in suburban, less downtown. This is based on European experience of UMTS, but I'm pretty sure you'll find more than five sites per carrier in SF.

Certainly a good question to be asking. Nice blog.

Richard,
thanks for the comment. I think you are right and I've updated the corresponding paragraph. Thanks,
Martin
