Canadian wireless, wireline and broadband operator Telus Corp has begun work on doubling the maximum theoretical data speed of its mobile network to 42Mbps by the first quarter of 2011, reports The Globe and Mail. Currently, peak download capability of 21Mbps is supported via HSPA+ technology across the national 3G network which Telus launched in partnership with Bell in November 2009 under a cost-saving agreement. The new upgrades, currently in laboratory testing, allow Dual-Cell compatible devices to access data services at up to 42Mbps in perfect conditions, though the company said it expects average commercial speeds to be around 8Mbps – roughly double the actual speeds experienced by its current HSPA+ users. Telus indicated the new, faster technology should become commercially available in the first quarter of 2011, with a wireless modem to be the first compatible device available over the network. Handsets with the capability to take advantage of the new speeds are not expected to be released for a further year.
