This document summarizes the evolution of mobile network technologies from 2G to 4G. It discusses the transition from early mobile networks focused on voice (GSM, 2G) to newer standards enabling mobile internet access and data (3G, 4G). Key points include: - 2G provided basic voice and small screen data, while 3G added higher speeds and capabilities like video calling - 4G networks like LTE provide the fastest speeds for mobile internet access to date, with peak downlink speeds over 1 Gbps - As speeds and capabilities increased, the number of mobile broadband subscribers grew while fixed lines declined, showing a shift to wireless connectivity
