The document discusses the evolution of mobile communications technology from 1G to 5G. 1G networks in 1991 used analog technology and could transmit voice calls. 2G digital networks in the early 1990s enabled SMS and MMS messaging. 3G networks in 2001 provided broadband connectivity and allowed for mobile internet, video calls and mobile TV. 4G launched in 2010 and increased data rates further, supporting HD video streaming and cloud services. 5G which will deploy from 2020-2030 is expected to deliver fiber-like speeds, support new applications and connect many devices through ubiquitous connectivity.
