Ericsson promises 42Mbps HSPA demo using multi-carrier technology

by Darren Murph posted Feb 11th 2009 @ 12:26PM

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!

Super 3G hits 250Mbps downlink in NTT DoCoMo field test

Just think -- this time next year, we'll all look back at this milestone and wonder how on Earth we thought it was impressive. For now, however, we wouldn't blame you for high-fiving everyone around, as NTT DoCoMo has stretched the boundaries again with a recent Super 3G field test. Reportedly, the outfit was able to record "a downlink transmission rate of 250Mbps over a high-speed wireless network in an outdoor test of an experimental Super 3G system," and while it's not quite the 300Mbps we'd heard about before, you won't find us kvetching. If all goes to plan, the firm is hoping to "complete development of the technologies required for the eventual launch of a Super 3G network" by 2009, but who knows how long we Americans will have to wait to indulge after that.
