I contains several interesting points and that old article certainly sounds authoritative as John Major was, I believe, president of QCOM for a short period before being reassigned to the MSFT-QCOM joint venture called Wireless Knowledge. Yet the paragraph which you quote sounds very much like a description of the TDMA problem which I did not think applied to CDMA. Your first sentence also sounds a bit peculiar to me in the CDMA world. In fact there is something roughly equivalent to a channel, but it is one tenth the size that you say, to wit: 1.25 mhz. There is, to my knowledge, no limit to how many of those channels may be put together for more capacity except the FCC licensed spectrum which a company controls. The need for 1.25 is not exact. It is actually 1.2268 mhz but there are guard bands necessary on either side so that only 3 of these channels can be used in 5 mhz of spectrum and 7 in 10 mhz.
