GSM vs DCS vs PDC-Difference between GSM,DCS,PDC standards

This page on GSM vs DCS vs PDC describes difference between GSM, DCS and PDC standards. GSM is the short form of Global System for Mobile Communication. DCS is the short form of Digital Communication System. PDC is the short form of Personal Digital Cellular standard.
