Rogers promised that October 1st would be a grand day for its LTE expansion plans, and we're now learning that it might have been underpromising to overdeliver later. The carrier just flicked the 4G switch for 18 cities and regions, or eight more territories than it had promised just two weeks ago. Most of the coverage still focuses on the southern tip of Ontario, including London, the Oshawa area and RIM's hometown of Waterloo, but there's a much more trans-Canada bent to the official deployment. Western cities like Saskatoon and Victoria now fit into Rogers' LTE map beyond a previously announced Edmonton, while the Quebec rollout is going past Quebec City to include Sherbrooke and Trois-Rivières. All told, the one day of growth is enough to supply Rogers LTE to almost 60 percent of Canada's population -- a convenient figure when one of the year's more important LTE smartphones just became available less than two weeks prior.
