This paper explores the Third Generation Partnership project—Release 99 (3GPP) wireless networking standards from an infrastructure (both core and radio access), terminals and applications vantage point. It provides a chronological perspective of how we got from Second Generation (2G) wireless systems to the 3G standard known as Universal Mobile Telecommunications System / Wideband – Code Division Multiple Access (UMTS / W-CDMA) technology and why it relies so heavily on Asynchronous Transfer Mode (ATM) and its low latency, high QoS capabilities for wireless and video delivery.
