A difference of opinion here. Is it just a matter of time and research before OFDM takes over?,...is the time now?,...or is this just a QCOM lover that refuses to believe ODFM could take out CDMA?? He does claim to be some kind of consultant in this industry,...perhaps you two should have a discussion on G & K thread or here.

The question here is whether ODFM is a genuine displacement of CDMA.
Indeed it is not. Certainly Wi-LAn has set a goal of putting OFDM onto one CMOS chip, this would bring it leagues closer. However, the technology just requires far too much power to be of practical use in a power scarce handset. It won't cut it anytime soon in that regard.
OFDM could shine brightly in the fixed market and in the automarket, possibly even in the satellite market, but it is nowhere near being ready for the handset market.
Another area where OFDM may shine, and Phillips is pushing this, is in the home networking, set-top box market. We will just have to see how this plays itself out.
But in regard to QCOM, the only place OFDM will displace it is in a fixed wireless setting, or some mobile setting where low power is not so crucial.

P.S. Oh yes, the other problem, line-of-sight. Not good for the mobile market at all. OFDM requires line-of-sight to work. At least last time I checked, which was this summer when I was recommending it for some future consumer applications for our wireless strategy. |
