3G Standards
 3G Standard is created by ITU-T and is called as IMT-2000.
 The aim of IMT-2000 is to harmonize worldwide 3G systems to provide Global Roaming.
3G OR UMTS Network Architecture
3G Technical Specifications:
 The transfer rate for 3G networks is between 144 and 2mbps (kilobits per second) for devices that are moving fast and 384 kbps for slow ones(like for pedestrians). For fixed wireless LANs, the speed goes beyond 2 Mbps.
3G makes possible a world of mobile multimed
WHAT IS NEXT GEN..?
NEXT IS 3.5G:
3.5G or HSDPA (High Speed Downlink Packet Access) is an enhanced version and the next intermediate generation of 3G UMTS. It comprises the technologies that improve the Air Interface and increase the spectral efficiency, to support data rates of the order of 30 Mbps. 3.5G introduces many new features that will enhance the UMTS technology in future. 1xEV-DV already supports most of the features that will be provided in 3.5G. These include:
 Adaptive Modulation and Coding
 Fast Scheduling
 Backward compatibility with 3G
 Enhanced Air interface
4G: Anytime, Anywhere Connection
