2G cellular system
Quick Summary
The 2G cellular system, also known as the Global System for Mobile Communications (GSM), marked a significant advancement in mobile telecommunications. It transitioned from earlier analog systems (1G) to digital technology, enabling improved voice quality and introducing new data services.12
Key features of 2G systems include:
* Digital Communication: Unlike 1G, 2G uses digital signals, which are more efficient and secure.1
* Enhanced Services: 2G introduced services like text messaging (SMS) and basic data transmission, laying the groundwork for mobile internet access.1
* Wider Coverage: By dividing service areas into smaller "cells," each with a base station, 2G technology allowed for more efficient use of radio frequencies and greater capacity, enabling more users to connect simultaneously.1
* Handoff: As users moved between cells, calls were automatically transferred without interruption, a process known as handoff.1
These developments made mobile phones more accessible and functional, paving the way for the sophisticated mobile technology we use today.1
