Ericsson set to demo 42 Mbps end-to-end HSPA Evolution technology
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.

So this claim of 42 mbps will end up being an actual speed of 4.2 mbps, right?

I'd be happy with a *real* 2Mbps.

problem is that whilst the over the air protocol is in theory capable of very high speeds, there are many problems with actually achieving them. in no particular order, traditional radio propagation problems: multi-path signals, atmospheric effects, fading, interference, etc, which are ameliorated by clever design of protocol and error correction, but never entirely eliminated. secondly, the OTA bandwidth is going to be shared, at least to some extent, so you might get peak rates at this speed but not sustained especially if the cell is busy.
however, the chances are that the biggest problem is nothing to do with whether you're on 2, 2.5, 3G, wifi hotspot etc - the operators often simply don't put in sufficient backhaul bandwidth to each site to either allow the cell to operate at max bandwidth, or even for the aggregated traffic to operate at that speed.

Sony Ericsson P5i/Paris FTW!!!
SE is going to rock CTIA!

That is all fine and dandy but how will it work with 100+ people hammering the tower?

Coming to Japan tomorrow.
Coming to America when hell freezes over.

Ericsson has a good tradition technically. They always had the power to pump up good technologies out their door. The bad part of this company is the managemnt team - always ready to screw up, no clear direction . Sometimes I wonder until when they will be able to innovate with the mentality they have crafted in their higher levels. Good that I got rid of my Ericsson's shares long time ago.
