Videotron Ltd. said Wednesday that it is testing and plans to roll out new HSPA+ dual carrier technology in the spring that will support mobile network speeds of up to 42 Mbps. In a release, Videotron said the new technology is fourth-generation, or 4G, under a designation of the International Telecommunications Union (ITU). The company, a subsidiary of Quebecor Media Inc., said it has also introduced “direct tunnel” technology, “which sends mobile data over the network by the most direct route, reducing the latency delay on the network and thereby optimizing the effectiveness of data transmission.” Videotron added that it will also roll out mobile services to new markets this spring, in Saguenay in April and Gatineau in late May. In the coming months, the company will also begin carrying its first tablet computer, it said. "Our 4G network is one of the most powerful and upgradable networks in Quebec," Robert Depatie, president and CEO of Videotron, said in a release. He added that the company’s mobile mobile network is "powerful" and supports multiplatform content distribution because based on a wired network of more than 25,000 kilometres of fibre optic cable. "he fact that more than 90% of our antennas are linked by fibre optics to our wired network gives our customers the full benefit of technological convergence. Examples include multi-screen pause and resume, remote programming of the customer's personal video recorder (PVR), and voice mail to email."
