For some reason I think CDMA could suffer from crosstalk in certain circumstances, but it was something relatively obscure, like one device had to be above another (like an apartment building), but otherwise in the same/similar coordinates, and then certain code assignments would allow crosstalk to happen. It was weird, because it could be one direction only. Unfortunately I don't really remember the details, since I worked on the core data network at the time.
