The third-generation concept started in 1992, when ITU issued a blueprint calledthe Internet Mobile Communication 2000 (IMT-2000). The blueprint definessome criteria for third-generation technology as outlined below:o Voice quality comparable to that of the existing public telephone network.o Data rate of 144 kbps for access in a moving vehicle (car), 384 kbps for access as the user walks (pedestrians), and 2 Mbps for the stationary user (office or home).o Support for packet-switched and circuit-switched data services.o A band of 2 GHz.o Bandwidths of each channel is 2 MHz.o Interface to the Internet.
