Ericsson isn't the only company eagerly waiting to release HSDPA Evolution - so is the whole 3GPP bandwagon and every vendor from Tokyo to San Francisco, including Qualcomm, that plays the CDMA group against the GSM group but makes money from both.

So unless you think you're right and every one one of these companies is wrong because you HAVE done some research, chill out.]]>Mar 27th 2008 9:50PMhttp://www.engadgetmobile.com/2008/03/27/ericsson-set-to-demo-42-mbps-end-to-end-hspa-evolution-technolog/http://www.engadgetmobile.com/2008/03/27/ericsson-set-to-demo-42-mbps-end-to-end-hspa-evolution-technolog/
Get ready to get schooled.

This is NOT about LTE, or GSM or CDMA, it's about Ericcson's fool move pushing QAM.

Are you actually arguing that just because it's big business they know better? Whatever is popular is correct? Do some math, learn some physics, QAM vs. OFDM, OFDM wins and that's why it IS part of the 3GPP roadmap.

NONE of these companies are pushing QAM for the future, except for now Ericcson.

STOP making fool assumptions about what "every one of these companies" is doing.]]>Mar 27th 2008 10:02PMhttp://www.engadgetmobile.com/2008/03/27/ericsson-set-to-demo-42-mbps-end-to-end-hspa-evolution-technolog/http://www.engadgetmobile.com/2008/03/27/ericsson-set-to-demo-42-mbps-end-to-end-hspa-evolution-technolog/Mar 27th 2008 10:59PMhttp://www.engadgetmobile.com/2008/03/27/ericsson-set-to-demo-42-mbps-end-to-end-hspa-evolution-technolog/http://www.engadgetmobile.com/2008/03/27/ericsson-set-to-demo-42-mbps-end-to-end-hspa-evolution-technolog/haha. but seriously. in the end its not always about blazing fast speed. feasibility and price is also a factor in adoption. No i have no idea what differentiates QAM from GMS or CDMA but i know that if they are the only company pushing it, there is no competition to push prices down, and there is no reason to bring it to the market to the first place if only one manufacturer is gonna support it.
and if QAM is more common than i understand it to be...let me know.]]>Mar 27th 2008 11:37PMhttp://www.engadgetmobile.com/2008/03/27/ericsson-set-to-demo-42-mbps-end-to-end-hspa-evolution-technolog/http://www.engadgetmobile.com/2008/03/27/ericsson-set-to-demo-42-mbps-end-to-end-hspa-evolution-technolog/Mar 28th 2008 12:36AMhttp://www.engadgetmobile.com/2008/03/27/ericsson-set-to-demo-42-mbps-end-to-end-hspa-evolution-technolog/http://www.engadgetmobile.com/2008/03/27/ericsson-set-to-demo-42-mbps-end-to-end-hspa-evolution-technolog/
evengrift, there's an engadget article from yesterday announcing EDGE Evolution from Nokia Siemens Networks : http://www.engadgetmobile.com/2008/03/27/nokia-siemens-rolling-out-edge-evolution-for-double-the-speed-in/
You won't find me on that post denouncing the technology because the rest of the world has moved on. I'm sure the incremental improvement being offered will be of value to some operators.

Coming back to this story, higher order modulation like 64QAM, when combined with 2x2 MIMO, helps reduce the gap between the spectral efficiency of HSDPA and LTE systems. It is an incremental improvement which is of significant importance to those network operators who do not yet want to invest the financial resources required to roll out a new LTE network right now, or those who simply cannot afford to swap out their WCDMA network for LTE for many years to come.

If you see this announcement from Ericsson in the right light, it actually makes a lot of sense.]]>Mar 28th 2008 1:04AM
