Apparently not content to let Nokia Siemens have the upgraded mobile broadband spotlight to itself today, Ericsson has now announced that it's set to demonstrate what it's touting as the "world-first end-to-end HSPA Evolution technology" at CTIA next week. That, the company says, should allow for speeds up to an impressive 42 Mbps, a feat made apparently possible by a combination of higher order modulation technology (64QAM) and 2x2 Multiple Input Multiple Output (MIMO) antenna technology. As for the actual demonstration, Ericsson is only going so far as to say that it'll be conducted with an unspecified "handheld form-factor device" that's based on the Ericsson Mobile Platforms access technology. Other details are unsurprisingly pretty light at the moment, but we're betting Ericsson will have plenty more to say about it when they actually light things up at CTIA.
