What is 3G Technology?
3G is the next generation of technology which has revolutionized the telecommunication industry. Apart from increasing the speed of communication, the objective of this technology is to provide various value added services like video calling, live streaming, mobile internet access, IPTV, etc on the mobile phones. These services are possible because the 3G spectrum provides the necessary bandwidth.
3G Technology is designed for multimedia communication. It provides services like higher data transfer rates.One of its key visions is to provide seamless global roaming, enabling users to move across borders while using the same number and handset. According to ITU it is expected that IMT-2000 will provide higher transmission rates: a minimum speed of 2Mbit/s for stationary or walking users, and 348kbit/s in a moving vehicle.
Technologies of 3G
The 3G technology is comprised of basically three technologies, but it is not the reason for its name as 3G.
· CDMA2000 - Code Division Multiple Access.
TD-SCDMA - Time-division Synchronous Code-division Multiple Access.
· W-CDMA (UMTS) - Wideband Code Division Multiple Access.
Let’s take a look on what these technologies are.
