If it was on the QCOM boards, I would've missed it. You mean this?

Please find below a message from Yahoo! AWE thread which was repeated on the Rocket board. I think it says that the costs of implementing EDGE via TDMA are considerably less than 3G through CDMA/HDR. Perhaps the tech-brains in residence on this Board are able to dissect the arguments made. I certainly can't as I'm simply not sufficiently knowledgeable. Not stupid, just ignorant <g>.

CDMA VS. TDMA- FACTS not opinion

Again, this is hype of CDMA-HDR (QCOM) over TDMA/EDGE-1XTREME (MOT). Are you aware of Guilder's extensive CDMA holdings? As for timeliness, it will take 2-4 yrs for each tech to be deployed. Given that coverage for a fixed area requires more CDMA sites than TDMA would, negotiating all those tower rights with the recently consolidated tower sector should effectively cost more for CDMA. It further stands to reason that TDMA gear will occupy more cage space than CDMA to meet node capacity, but CLEARLY the cost metrics for deployment are in the TDMA camp. After all, TDMA EDGE is being developed by more than one patent holder. So, your argument of slow growth due to deployment delays is actually more impacting to CDMA. You must have been an English major to rewrite the truth as you did.
Again, "utilized at any interesting level" requires human interfaces that enable one to do so, AND if and only if, there are mature applications available to the user ALL AT A REASONABLE COST.
The network congestion you speak of is an issue resolved. For uninformed English majors such as yourself, when AT&T offered its Personal Communications package and Digital One Rate programs, it grabbed market share beyond its capacity. Do you think that lesson is lost? If so, maintain your ignorance.
"I think the modulation is too narrowband", and what do you think DSSS does under CDMA?!? How many discrete freqs does CDMA possibly use and reuse within a transmission? And you talk about TDMA being narrowband! So tell us genius, under HDR what happens in CDMA when a reused channel within the sequence NACK's? (Tell us this never happens.)
Nice try at the use of a little techno-speak. You and the ratsass are regurgitators, the remains of which lose their original flavor and show yourselves as shorts.
As for NTT, ask them yourself. It could be that Fujitsu couldn't do the job right the first time, and it will be adding corrected I-mode gear when it is produced. |
