UMTS is currently emerging as a global 3rd generation mobile
communications standard. For the first time, a global international
consortium has agreed on a common technology for the use in this
generation mobile cellular networks. However, three versions of the
radio air interface are defined in the 3GPP standards. One is based on
FDD with a chip rate of 3.84 Mcps for operation in a paired 2x5 MHz
band which is commonly known as WCDMA. The others consider TDD
operation in a single frequency band. One of the latter known as
TD-CDMA uses the same chip rate as the FDD mode and also 5 MHz
bandwidth. The Chinese TD-SCDMA option is included in the UMTS
standards as the TDD 1.28 Mcps option and is operated in 1.6 MHz
bandwidth. All modes are closely related since e.g. the layer two and
three protocols are harmonized to a large extent.
This thesis presents a fair comparison of the performance of the three
radio access modes with respect to network capacity under different
traffic conditions including voice, video and web services. The study
comprises analytical models based on information theory as well as
complex dynamic event-driven simulations in order to derive and
compare the spectral efficiency taking into account the various radio
resource management algorithms. Moreover, inter-working with GSM
networks and future enhancements like HSDPA which enables a TDMA
component for the FDD mode and allows for data rates up to 10 Mbps are
addressed.
The aim of this thesis is to provide substantial information and
performance aspects of all the UMTS radio access modes. The results
can help researchers, manufacturers, network planners and operators to
realistically dimension their UMTS network with respect to the
environment, service mixture and protocol algorithms applied.
