Third Generation Cellular Networks (commonly referred to as 3G) represent the next phase in the evolution of cellular technology, evolution from the analog systems (1st generation) and digital systems (2nd generation). 3G networks will represent a shift from voice-centric services to converged services, including voice, data, video, fax and so forth.

UMTS is the dominant 3G solution being developed, representing an evolution from the GSM network standards, interoperating with a GSM core network. The 3G will implement a new access network, utilizing both improved radio interfaces and different technologies for the interface between the access network and the radio network.

UMTS will use a wideband CDMA technology for transmission, and a more efficient modulation than GSM. This will allow UMTS to reach higher utilization, and offer higher bandwidth to the end-user. UMTS also implements an ATM infrastructure for the wireline interface, using both AAL2 and AAL5 adaptations; AAL2 for real-time traffic and AAL5 for data and signaling.
