The document provides an overview of Global System for Mobile Communications (GSM) including its architecture, modulation techniques, and frequency allocation in India. It discusses the key components of GSM architecture like the Base Station System (BSS), Network Switching Subsystem (NSS), and Operations and Maintenance Center (OMC). It also covers the evolution of GSM networks from 2G to 2.5G GPRS networks and increases in data rates. Finally, it lists India's frequency allocation plan and the frequency bands designated for mobile services, broadcasting, Wi-Fi and other applications.
