4G is not a single technology but a collection of technologies that create fully packet-switched networks optimized for data transmission. 4G networks are projected to provide speeds of 100Mbps for mobile users and 1Gbps for stationary users. The development of wireless technology progressed from 1G which used analog signals for early mobile phones, to 2G which used digital signals and had better quality and capacity, to 3G which enabled broadband capabilities and multimedia support, to 4G which provides faster speeds and more services including mobile gaming and broadband access in remote areas. Research into 5G networks is already underway to continue advancing mobile communication technology beyond 4G.
