>From the article:
"Consumers would be able to buy broadband access of 1 million to 3 million
bits per second for $18 to $24 a month -- a bit slower than wired cable
modem service but about half the price. The network also is expected to
create an economic incentive for businesses to locate in Minneapolis".

The Star Tribune article's statement that wireless access will be "a bit
slower" than current cable access isn't correct and the issue of wireless
speed versus that of current cable or DSL needs clarification. 

This is important because while wireless access is much cheaper than current
DSL or cable, I don't think consumers would be much interested in a service
that takes their internet access backwards speed wise. I also don't want us
city consumers - residential or commercial - to set our expectations about
wireless internet access low, especially given that in Minneapolis the
service will be owned and operated by a private (s) company unlike in other
cities (Chaska, Philadelphia, San Francisco), where the municipalities
themselves provide (or will provide) the service at faster speeds and
cheaper rates than current cable and DSL service.  

I have always understood that wireless was not just faster, but
significantly faster, than current cable or DSL, so I started with a call
for clarification to Bill Beck, the lead person on this at city hall. He
confirmed that wireless access speed, at 1 to 3 megabits per second (Mbps),
will be faster than DSL at 0.3 to 0.4 Mbps and cable at 0.6 to 0.7 Mbps. 

For comparison (from other sources):

-Wireless Protocol 802.11g (note the g)gets up to 54 Mbps 
-Wireless Protocol 802.11b (not the b)gets up to 11 Mbps 
-Cable and DSL generally download between 0.256 Mbps and 5 Mbps and upload 
between 0.128 Mbps and 1 Mbps
-56k Dial-up modem is equivalent to 0.056 Mbps
-28.8k Dial-up modem is equivalent to 0.0288 Mbps

Based on the speed being reported by the city, I assume that the city
wireless system will use the 802.11b protocol. This appears to be the norm
for city-wide public access:

Chaska, MN  0.25 to 3 Mbps using 802.11b
(http://www.chaska.net/mkpage.cgi?services_residential_connect+residential_d
etails)
Buffalo, MN  up to 1.5 Mbps (http://www.bwig.net/)
Philadelphia, PA is proposing to use 802.11b
(http://www.phila.gov/wireless/faqs.html)

The differences between the 802.11 protocols are discussed here:

Also in the news - San Francisco considers going the way of Philadelphia -
playing a central role in setting up and providing wireless access service.
