1G (First Generation) Cellular Networks:
- 1G cellular networks are analog systems that were developed in the 1980s.
- They use frequency modulation for transmission of voice signals.
- The basic characteristic of 1G networks is that they only support voice calls and have limited data transfer capabilities.
- Advantages of 1G networks include their ability to provide basic voice communication and coverage in remote areas where landline infrastructure is lacking.
2G (Second Generation) Cellular Networks:
- 2G cellular networks were developed in the 1990s and are mainly digital systems.
- They use digital modulation for transmission of voice signals and support limited data services such as SMS and MMS.
- The basic characteristic of 2G networks is that they allow for more efficient use of bandwidth and improved call quality compared to 1G networks.
- Advantages of 2G networks include increased data transfer speed, improved call quality, and the ability to support basic data services such as messaging.
3G (Third Generation) Cellular Networks:
- 3G cellular networks were developed in the early 2000s and are designed to support high-speed data services in addition to voice calls.
- They use packet-switched transmission for both voice and data signals.
- The basic characteristic of 3G networks is that they provide faster data transfer speeds and support services such as video calling, mobile internet, and mobile TV.
- Advantages of 3G networks include faster data transfer speeds, improved multimedia capabilities, and the ability to support advanced services such as video calling and mobile internet browsing.
Overall, the evolution from 1G to 3G networks represents advancements in cellular technology that have led to improved voice quality, faster data transfer speeds, and increased capabilities for mobile communication and connectivity.
