Data Throughput Evaluation of Internet Users over UMTS Wireless Network

Although voice is a mandatory service in the wireless telecommunication networks, most of new data services are based on Internet These services include http, telnet, SMTP, etc. In addition, mobile channel is a multipath fading channel. TCP/IP performance in the wired systems depends on the link congestion and packet loss. In this paper we study how TCP/P protocol is used in UMTS and survey its performance reduction in a multipath fading channel alone and with an ARQ protocol. KEYWORDS Internet, TCP/IP Protocol Performance, Fading Channel, UMTS.
