3G (Third Generation) Technology:

Overview:

  • Purpose: 3G was developed to provide higher data rates, increased capacity, and support for multimedia applications compared to its predecessor, 2G (Second Generation).
  • Data Rates: 3G networks typically offer data rates ranging from 144 kbps (kilobits per second) to several Mbps (megabits per second).
  • Technology Standards:
    • CDMA2000 (Code Division Multiple Access): Used mainly in North America and parts of Asia.

4G (Fourth Generation) Technology:

Overview:

  • Purpose: 4G is an evolution of 3G and was designed to provide even higher data rates, lower latency, and improved system capacity.
  • Data Rates: 4G networks offer significantly higher data rates compared to 3G, ranging from 100 Mbps to 1 Gbps.
  • Technology Standards:
    • LTE (Long-Term Evolution): The most widely adopted 4G standard globally.
