0G to 5Gl
Mobile wireless technology has progressed through several generations from 0G to 4G, with 5G currently being implemented. Early mobile radio telephone systems (0G) preceded 1G networks in the 1970s, which allowed for analog mobile communication. 2G digital networks replaced 1G analog networks in the 1990s, introducing features like text messaging. 3G and 4G networks further increased data speeds and capabilities for multimedia and internet use on mobile devices.
