3G demystified

Description

This course is designed to give the delegate an
understanding of the technologies used within a 3G
UMTS mobile network. During the course we will
investigate the UMTS air interface and the use of
Wideband-Code Division Multiple Access (WCDMA) to
facilitate high speed data access, together with HSPA
to offer mobile broadband services. We will describe
the use of soft handover rather than hard handover
procedures and soft capacity sharing. The course
includes a brief exploration of the UMTS protocol stack
and the use of PDP Context and QoS support features.
