Sure! Here’s a brief overview of the evolution of mobile networks from 1G to 6G:

1G (First Generation)

1G (First Generation): This was the first generation of mobile networks, which used analog technology to transmit voice signals. 1G was introduced in the 1980s and had limited capacity and poor call quality.

2G (Second Generation)

2G (Second Generation): This was the second generation of mobile networks, which used digital technology to transmit voice signals. 2G was introduced in the 1990s and provided improved call quality, capacity, and security. 2G also introduced SMS (Short Message Service) which allowed for text messaging.

3G (Third Generation)

3G (Third Generation): This was the third generation of mobile networks, which introduced mobile data services and enabled faster data transmission. 3G was introduced in the early 2000s and offered data speeds of up to 2 Mbps, which enabled features like mobile internet, video calling, and mobile TV.

4G (Fourth Generation)

4G (Fourth Generation): This was the fourth generation of mobile networks, which introduced even faster data transmission speeds and improved network efficiency. 4G was introduced in the mid-2000s and offered data speeds of up to 100 Mbps, which enabled features like high-quality video streaming, online gaming, and cloud services.

5G (Fifth Generation)

5G (Fifth Generation): This is the fifth generation of mobile networks, which offers even faster data speeds and lower latency. 5G was introduced in the early 2020s and offers data speeds of up to 10 Gbps, which enables new features like augmented reality, virtual reality, and self-driving cars. From 5G Onwards, the propagation of radiowave has been studied a lot as it plays an important role in 5G+ network planning and optimisation.

6G (Sixth Generation)

6G (Sixth Generation): This is the upcoming sixth generation of mobile networks, which is expected to offer even faster data speeds and lower latency than 5G. 6G is expected to be introduced in the late 2020s or early 2030s and is expected to enable new technologies like holographic communications, brain-computer interfaces, and advanced artificial intelligence.
