In the 1990s, the 'second generation' (2G) mobile phone systems emerged. Two systems competed for supremacy in the global market: the European developed GSM standard and the U.S. developed CDMA standard.

Native IP networks - 4G
By 2009, it had become clear that, at some point, 3G networks would be overwhelmed by the growth of bandwidth-intensive applications like streaming media.[20] Consequently, the industry began looking to data-optimized 4th-generation technologies, with the promise of speed improvements up to 10-fold over existing 3G technologies -
Mobile Broadband data - 3G
The main technological difference that distinguishes 3G technology from 2G technology is the use of packet switching rather than circuit switching for data transmission
