Advanced explanation:
2G, also known as GSM (Global System for Mobile Communications), was the first fully digital generation of mobile communications and was introduced in the 1990s. It utilised Time Division Multiple Access (TDMA) and Frequency Division Multiple Access (FDMA) technologies to enable more efficient use of frequency bands. 2G enabled digital voice communication and offered the possibility of sending SMS (Short Message Service) and MMS (Multimedia Messaging Service) for the first time. The data transfer rate was very low compared to later technologies, with maximum speeds of around 200 kbps (GPRS and EDGE). However, it laid the foundation for secure and encrypted communication standards.
