    Keywords : HSDPA; packet scheduler; performance;

    Abstract : The introduction of a new technology High Speed Downlink Packet Access (HSDPA) in the Release 5 of the 3GPP specifications raises the question about its performance capabilities. HSDPA is a promising technology which gives theoretical rates up to 14.4 Mbits. READ MORE

  5. 4. Performance Evaluation of TCP Variants over UMTS Networks

    University essay from Institutionen för informationsteknologi

    Author : Nikunj Modi; [2008]
    Keywords : ;

    Abstract : With the evolution of 3G technologies like Universal Mobile TelecommunicationSystem (UMTS), the usage of TCP has become more popular for a reliable end-to-end (e2e) data delivery. However, TCP was initially designed for wired networks and therefore it suffers performance degradation due to the radio signal getting affected by fading, shadowing and interference. READ MORE
