3G is the next generation mobile technology offering higher speeds on both uplink (up to 5.7 Mbps) and downlink (up to 28 Mbps). It will enable a host of rich multimedia services such as video calling, video on demand, and provide a richer experience for existing services such as mobile internet, mobile TV and MMS.
3G networks operate on technology called High Speed Downlink Packet Access (HSPA). Data is transmitted many times faster than earlier 2G networks. This basically means that in addition to the earlier audio, graphics, and text, you can now send and receive video content too — provided you have a 3G-enabled handset or USB datacard and are in 3G coverage areas.
