Network World Canada provides a little back and forth between telco Rogers Communications and Toronto Hydro: The former backs WiMax as the coming thing, so why bother with Wi-Fi. The latter once had plans for a large city-wide Wi-Fi network, and defends that technology's ubiquity and cost. Mobile WiMax isn't yet mobile; Wi-Fi is. WiMax in Canada is enormously more expensive in this pre-standard version: C$45 to C$65 per month; Toronto's Wi-Fi, C$29.
Only problem? Toronto's Wi-Fi network hasn't increased in area for some time, and the head of the company, quoted in this article extolling Wi-Fi, fails to mention its tiny size. It was rated very heavily by Novarum, a testing firm, partly because of the density of access points installed. Their six sq km network has under 4,000 users, and they went say how many below. But they won't build the network further until subscribers top that figure.
