The evolution of mobile communication networks has been nothing short of impressive. From the first generation (1G) analog systems to the latest 6G technology, the speed and capabilities of mobile networks have drastically increased. One crucial aspect of these networks is the frequency bands they use to transmit data and voice signals. In this article, we'll take a closer look at the network bands from 2G to 6G.

2G Networks: The second-generation (2G) network was introduced in the early 1990s and was the first digital mobile communication system. The two main network technologies in use were GSM (Global System for Mobile Communications) and CDMA (Code Division Multiple Access). GSM operates in various frequency bands, including 850MHz, 900MHz, 1800MHz, and 1900MHz, while CDMA primarily operates on the 850MHz and 1900MHz bands. 2G networks provide basic voice and text services, with limited internet access.

3G Networks: Third-generation (3G) networks were introduced in the early 2000s, and they significantly improved mobile internet speeds. The two primary 3G network technologies are CDMA2000 and UMTS (Universal Mobile Telecommunications System). These networks operate in frequency bands such as 850MHz, 900MHz, 1700MHz, 1900MHz, and 2100MHz. With 3G, users could enjoy faster data transfer rates, making it possible to browse the web and stream videos.

4G Networks: Fourth-generation (4G) networks were introduced in the late 2000s, and they provided even faster internet speeds and lower latency than 3G networks. 4G networks operate in frequency bands such as 700MHz, 850MHz, 1800MHz, 1900MHz, 2100MHz, and 2600MHz. With 4G, users could enjoy high-definition video streaming and faster downloads and uploads.

5G Networks: The fifth-generation (5G) network was introduced in the late 2010s, and it promises to revolutionize mobile communications. 5G networks operate in frequency bands such as 700MHz, 850MHz, 1900MHz, 2100MHz, 2600MHz, and 39GHz. 5G networks offer significantly faster internet speeds than 4G, with the potential to reach up to 20Gbps. Additionally, 5G networks offer much lower latency, which is essential for applications that require near-instantaneous response times.

6G Networks: The sixth-generation (6G) network is still in the development stage, but it promises to offer even faster internet speeds and more advanced features than 5G. While the frequency bands for 6G have not yet been finalized, some potential bands include the terahertz (THz) range, which offers even faster data transfer rates than the microwave bands used by 5G networks. With 6G, we can expect to see the development of even more advanced applications, including augmented reality and virtual reality.

In conclusion, mobile communication networks have come a long way from the basic voice and text services offered by 2G networks to the advanced capabilities of 6G networks. As the technology continues to evolve, we can expect even faster internet speeds, lower latency, and more advanced applications to become a reality
