GSM and CDMA Based Communication System

Abstract

Cellular mobile services have been around for a while and are continuously developing today. Numerous communication services, including CDMA and GSM, developed alongside these services. The two most significant technical standards for mobile communication are CDMA and GSM. The GSM and CDMA both transform mobile phone data into radio waves. However, these technologies differ in terms of how calls and data transfer occur through a network. One of the primary distinctions between CDMA and GSM is that CDMA doesn't require a SIM card and instead relies on ESNs to link a mobile phone to its network (Electronic Serial Number).
