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

The main technological difference that distinguishes 3G technology from 2G technology is the use of packet switching rather than circuit switching for data transmission
