This document discusses the evolution of wireless communication technologies through 5 generations. It begins with pre-generation analog mobile radio systems from the 1950s. The 1st generation systems introduced in the 1960s provided basic voice calling. 2nd generation systems from the 1990s added digital signaling and SMS. 3G in the late 1990s provided multimedia and higher speeds up to 2 Mbps. 4G LTE networks from 2008 offered further increased speeds and capabilities. The document concludes by mentioning the vision for 5G networks by 2020 which will support more immersive experiences like virtual reality.
