Please don't leave out the required Sprint CellPhone Service & 2 year contract, frankieboy. http://www.sprint.com/business/products/offers/offerHighSpeed_byProduct.html

For intercity roamers, Sprint-like services may be your best option for a while.

But in the cities where most of us spend most of our online minutes, muni wireless is a serious threat to wireless phone/data carriers (Sprint, Verizon, Cingular, etc), just like satellite is to terrestrial radio. And major cellphone companies like Motorola, Nokia, & Sony Ericsson are all jumping aboard wifi... at least to hedge their bets.

A major advantage of muni wifi is much greater capacity and much lower latency...

The biggest case "for" is one of capacity... It's a matter of trivial mathematics that sharing spectrum over a small geographic area versus over a far larger cell site results in a much larger capacity per user. This is because that same spectrum can be re-used over and over. The result is that Wi-Fi can deliver some two orders of magnitude greater bits per second per square meter than cellular data networks. Simply consider a one-kilometer radius cell site versus a 100-meter radius Wi-Fi access point, and that's a hundred-to-one difference in coverage area.

Because of the simpler CSMA protocols and smaller networks, Wi-Fi also has inherently lower latency, less than 10 msec, whereas 3G networks are struggling to get down to 100 msec. As a result, Wi-Fi provides a better broadband experience and scales better for dense user configurations. Another pro is the prevalence of Wi-Fi-equipped computers, whether notebooks or handhelds. The architecture of mesh makes a lot of sense, too, namely that only a subset of access points need a connection to a wireline infrastructure. With standardization coming through IEEE 802.11s, we'll eventually have interoperable mesh infrastructure. And with VoIP becoming a reality for Wi-Fi, even voice service becomes a possibility.

This should all translate into better service at lower cost. Then there's WiMax that will improve the range of muni wireless dramatically.

And, for road warriors who stocktrade @ 80 mph, perhaps MOBL and others will someday make the intercity wifi experience more seamless. http://www.wi-fiplanet.com/tutorials/article.php/3599726
