already claimed the title of World's First on this one, but Telus up in Canada isn't far behind, becoming the first carrier in North America to push HSPA+ up to 42Mbps through the magic of dual carrier technology. The concept, of course, is nothing new -- remember those "Shotgun" two-line 56k landline modems back in the day? Dual carrier isn't much different, employing two HSPA+ connection simultaneous to get an effective max theoretical throughput of 42Mbps. Telus has already wrapped up lab trials, but it expects to offer the blazing speeds to customers some time in the first quarter of 2011 with the launch of the first compatible devices -- USB modems at first, we'd presume -- and since Bell shares the network with Telus, we'd imagine that they're in cahoots on this as well. Rogers, ball's in your court. Follow the break for the full press release.
Update: Bell reached out to us to let us know that they're in the thick of testing dual carrier HSPA+ as well with trials on real-world cell sites kicking off this month, and that "no one's ahead of Bell in testing this technology." As we mentioned before, Bell and Telus are in bed with each other for their HSPA airwaves, so it makes perfect sense.
