Per my understanding, due to AMPS signal co-existing with CDMA signal, there is Single Tone Desense (STD) spec for CDMA. I know that in WCDMA there are blockers spec for GSM signal. How about AMPS for WCDMA? I think that they could be operating in the same frequency. For example, CDMA cell band center frequency is 836.5MHz, and WCDMA band 5 center freqeuncy is 836.5MHz. Why AMPS signal will not bother WCMDA like CDMA? My only guess is that operators could make sure not to let AMPS co-exist with WCMDA.

Also I would like to know if any carrier uses AMPS as I doubt about it.
