Leave Ericsson alone for five seconds, and it goes and makes the technology it was just bragging about seem archaic. Just in case Telstra's 21Mbps Next G network seemed a bit -- how do you say, sluggish? -- Ericsson will be showcasing a new approach that enables peak downlink data rates of 42Mbps at Mobile World Congress. In order to achieve such tremendous speeds, it will rely on its so-called multi-carrier technology, which is the next (or is that next-next?) generation of HSPA. The secret? It allows users to "receive data simultaneously on two frequency channels," which doubles the data rate in the coverage area of an HSPA network and on the cell edge. The best part of all this isn't that you can one day look forward to crushing your cable modem with a wireless USB stick, it's that "one day" will be ready to happen before the dawn of 2010. Huzzah!
