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.
