TeliaSonera already upgrading LTE network, 'practical speeds' of up to 80Mbps promised

There's no rest for the wicked -- and perhaps nothing in the world of wireless describes "wicked" better than Nordic carrier TeliaSonera, which holds the distinction of having deployed the world's first commercial LTE network last year. Thing is, the network's been taking a little heat for being effectively no faster than some of the recent HSPA+ deployments around the globe, but no worries -- they're already working on it. It seems that central Stockholm is the first area to benefit from upgrades that will take the LTE airwaves to a theoretical max of 100Mbps with "practical" downlink throughput alleged to be down around 80Mbps, still a fine upgrade from the real-world peaks of 40Mbps that folks have been seeing so far. If you're outside Stockholm, TeliaSonera expect to upgrade the rest of the LTE network in Spring. Where's the carrier suddenly finding all this extra bandwidth? It's said to be more of a backhaul upgrade than anything else, which sounds kind of familiar.
