摘要：
The International Telecommunication Union (ITU) began studies on globalization of personal communications in 1986 and identified long term spectrum needs for future "Third-Generation" mobile wireless telecommunications systems. These 3G mobile telecommunications systems are expected to provide worldwide access and global roaming for a wide range of services. This paper describes the proposed 3G air interfaces of Europe, Japan, and North America. This paper highlights ETSI activities in 3G arena and provides a brief description of the FRAMES Multiple Access (FMA) mode I and mode 2 air interfaces. Evolution of GSM and North American TDMA (TIA-IS-136) to Wide-band Code Division Multiple Access (W-CDMA) via EDGE system is also presented, as well as a discussion on industry trends.
