This document provides an overview of mobile generations from 1G to 4G. It discusses the key features and technologies of each generation. 1G used analog signals and FDMA. 2G was digital and used TDMA and CDMA. 3G was digital, used CDMA, and enabled broadband. WCDMA was the 3G air interface standard, which provided higher data rates and quality of service compared to prior standards. 4G networks were designed especially for high speed data transmission and support peak speeds over 100 Mbps for downloads and 50 Mbps for uploads. The document concludes with asking if the audience has any other questions.
