  1. 1. Evaluation of a Set of TCP Features over Narrowband Radio Bearer for Train Communication

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Pajtim Buzolli; Jakub Tadeusz Mucha; [2016]
    Keywords : TCP; TCP Features; Circuit Switched; GSM-R; Packet Switched; GPRS; Train Communication; Technology and Engineering;

    Abstract : An engineering approach to the evaluation of the TCP as a narrowband bearer for short messages in the low latency train-trackside communication scenario is described in this report. The project was developed in cooperation with Bombardier Transportation Sweden AB as a part of the “ETCS over GPRS” venture. READ MORE

  3. 2. Addressing non-conformities in a ERTMS implementation : Collecting non-conformities in ERTMS simulation and analyzing their management via a database

    Abstract : The global rail network every year is used to transport approximately 21 billion of people and 10 billion tons of cargo. These numbers is estimated that are going to increase in the future. Railway will become the transportation of the future. READ MORE

  5. 4. Is GSM-R the limiting factor for the ERTMS system capacity?

    University essay from KTH/Trafik och logistik

    Author : Gustaf Lindström; [2012]
    Keywords : ;

    Abstract : The European Rail Traffic Management System, ERTMS, is introduced as a common signalling system for the European railway network. ERTMS consist of two main parts, the signalling part ETCS and the radio transmission system GSM-R, based on the well-established GSM standard. READ MORE

  6. 5. On Models for Interference Calculations between Radio Communication Systems

    University essay from KTH/Signalbehandling

    Author : Fredrik Vihlborg; [2011]
    Keywords : ;

    Abstract : When installing a new radio system, it is of great importance to know that it will not interfere with the already existing systems, and that they can coexist side by side. The problems that will follow if interference occurs, can be of huge magnitude, e.g. radars not working, trains stopping etc. READ MORE
