Answer / telecom specialist

GSM refers to Global System for Mobile communications while
CDMA refers to Code Division Multiple Access.
Both are two diffrent technologies in Telcommunications and
behave diffrently in terms of giving voice and data
services to the customer.
Though GSM is globally used teschnology - CDMA technology
has more benefits in terms of call clarity, faster data
speeds etc while GSM covers most of the network areas and
has got variety of handsets to choose from, people prefer
this technology.
Other than these 2 technologies we have other technologies
like TDMA, WCDMA etc
