The “G” in 2G, 3G, 4G, and 5G stands for Generation, referring to the different stages of mobile network technology. Each new generation brings faster speeds, better reliability, and new capabilities—1G was analog, 2G introduced texting, 3G brought mobile internet, 4G enabled high-speed data, and 5G is revolutionizing connectivity with ultra-fast speeds and low latency. Future generations like 6G will continue to push the boundaries of wireless communication.
