Universal Mobile Telecommunications System
(UMTS) is a third-generation cellular network that
enables high-speed wireless Internet access. It can
provide maximum data-rates ranging from 64kb/s to
2Mb/s in different environmental types. UMTS is
designed to provide access to the existing Internet
services as well as to UMTS specific services. It will
augment the existing capabilities of 2G mobile
networks and GPRS, and one often envisaged strategy
is to offer a richer set of multimedia services. It is
widely known that TCP does not perform efficiently in
wireless links where the bit error rate is high enough.
This paper has as main target to evaluate the
performance of TCP data transfer over the UMTS air
interface, by means of a rather detailed simulation
model. We examine the performance of TCP over
UMTS Dedicated Channels (DCHs) with different bit
rates and Transmission Time Intervals (TTIs) and we
represent some simulation experiments for UMTS
High Speed Downlink Packet Access (HSDPA)
