Structure and Functionality of 2G
The structure of 2G networks involves key components such as base stations, mobile devices, and core network elements. Here's a breakdown of its functionality:
Base Stations or BTS (Base Transceiver Stations): These serve as access points for mobile devices, facilitating their connection to the 2G network. Base stations receive and transfer data signals, ensuring seamless communication between devices and the network.
2G-Enabled Devices: Devices like feature phones and early smartphones utilize the 2G network for basic services such as voice calls and text messaging. They are equipped with SIM cards for authentication and authorization.
Core Network Components: The core network encompasses elements such as the Mobile Switching Center (MSC) and the Gateway Mobile Switching Center (GMSC). These components enable call routing, data transfer, and overall network management.
