3G and 4G are mobile network standards, with 4G providing faster data transfer rates of up to 100 MB/sec compared to 3G's 3.1 MB/sec. 3G allows broadband internet and streaming of audio/video on mobile phones, while 4G provides ultra-broadband access and higher resolution mobile TV. Key differences include 4G having faster transmission speeds, supporting both LAN and WAN networks, and operating on higher frequency bands of 2-8 GHz versus 3G's 1.8-2.5 GHz. Mobile banking uses both 3G and 4G technologies to enable transactions like funds transfer and trading via mobile handsets.
