3. If this is correct, and spectrum is obviously a limited and valuable resource, why would anyone EVER adopt W-CDMA technology, if it requires 5 MHz, instead of 1.25 MHz ?
Basically, all things being equal, one would be able to pack more information on a wider channel. For example fast internet access(384kbit/s) or videoconferencing(3G) require a wider radio frequency band. Of course, we know, that NTT, Nokia,and others developed this W-CDMA standards/technology to try to avoid Qualcomm patents(unsuccessfully). On the other hand, QCOM built on Cdma-One(IS-95) to tackle the higher data rates required by 3G.(1x,3x,...)
