Introduction+to+3G+Mobile+Communications - 资源详细说明
The third generation (3G) mobile communication system is the next big thing
in the world of mobile telecommunications. The first generation included
analog mobile phones [e.g., Total Access Communications Systems
(TACS), Nordic Mobile Telephone (NMT), and Advanced Mobile Phone
Service (AMPS)], and the second generation (2G) included digital mobile
phones [e.g., global system for mobile communications (GSM), personal
digital cellular (PDC), and digital AMPS (D-AMPS)]. The 3G will bring
digital multimedia handsets with high data transmission rates, capable of
providing much more than basic voice calls.
