Paul, A couple of issues just to continue with our speculation thing: 1) 802.16a standard has not a final form yet, but the most important issues have moreless been defined. One of them is that it will use OFDM as a transport technology. 2) Wi-fi´s 802.11a and 802,11g also use OFDM. Therefore with little modification you can have, in the same chip, these 3 standards!!. The main difference being that you would need different radios to operate in different frequencies 2.4, 5.x GHz, etc. But as you may know, there are new software radio technologies that promise to solve this issue. So you could use 802.11g and 802.11a indoors and 802.16a mobile outdoors or in any combination you want. Why use only one or the other if you can have all three and use them according to the circumstances?. The issue here is that Wi-Fi and its related technologies are covering well the bases for the future and Qualcomm investors should take this into account. IMHO Wi-Fi will be a serious challenger to present and future GSM/GPRS/CDMA/W_CDMA cellular technologies that want to branch out its voice technology into data. Wi-Fi, was born as a data technology and holds a strong hand there. Take care, JAPG

Yes. The problem facing 802.16 is that there will be millions of 802.11 enabdled devices. I can see 802.16 being the 'wireless backbone MAN' but client site adoption seems unlikely unless 802.11X fails and 802.16 can fix the fatal flaw. There once were millions of AMPS cell phones out there too and CDMA was an inferior technology when judged against ubiquity of coverage etc. etc. Seems to me that OFDM is capable of doing to CDMA (and thus QCOM) what CDMA has done with AMPS. A sort of "innovator's dillema" in real-time IMHO. Substitution is the most insidious kind of competition, 'cause most of the time you don't even see it coming. John
