Ben, I doubt seriously that many munis want to appreciate major "direct" financial rewards through their wireless efforts. Local governments are more likely banking on the catalytic effects that improved communications will have on all aspects of community life, including boosting the local economy. Also, in theory, at least, upper layer service providers that rent space on municipal wireless or fiber systems should be able to make a buck if they market their services wisely. How does one assess the return on investment made by the municipality through increased tax revenues that result from improved communications services? Perhaps more profound than the effects of wireless is the effect that new fiber builds have on local economies, based on sheer capacity considerations alone. I've done site selections for institutions and one of the first things I look for as the owner's representative, after determining that potable water and electric power exists, is multiple fiber routes to a prospective site. Without the power and communications essentials being met, a locality doesn't stand a chance in hell to even be considered, much less attract a data center or other structure housing an IT work force. Fiber builds and municipal wireless networks represent a near perfect way for incumbent providers to partner with third party interests, but they refuse to do so. This refusal has been demonstrated time and again, most recently in UTAH where we see UTOPIA and iProvo, two builds that cover over a dozen cities throughout the state, being shunned (actually fought) by Qwest and the MSOs, entirely, which, IMO, is an especially egregious act, since some localities where these startups are going are not yet being serviced by fiber by either of the incumbents. And even though they could purchase wholesale capacity over these recently installed fibernets for a song, relative to the costs of building redundant routes themselves, they refuse. But I do digress, don't I? ;) Getting back to the lucrativeness (or lack thereof) of municipal wireless networks from a systems integrator's perspective, then, I see your point concerning going after alternative sectors. Mining, however, would not be the first choice that comes to my mind. Would you extend wireless via fiber or coaxial uplinks to work areas? Shafts and tunnels? Most wireless communications systems that I've come across in this space have used coaxial "Leaky Feeder" technologies, similar to those used in elevator shafts, subways, river and mountain crossing tunnels, and building basements. Would you spend a moment addressing this application? TIA. FAC

Hi BenWobbles, >>The combination of public safety and public access seems to be the best model so far.<< If you don't have Non-Line-Of-Sight spectrum (below 2 GHz), then you need Right Of Way to get Line-Of-Sight. Public safety gets you Line-Of-Sight. To add more detail about the vendor-specific slottime knob you are twisting, the way aAirPropogationTime is used in 802.11, it should include transmit processing delays in the most distant contending stations. The slottime you are setting should include round-trip time from your antenna to your antenna, including the internal delay in another station's attempt to transmit (CSMA Clear Channel Assessment). The other terms in the slottime definition take into account the internal delays within your own station.
