  1. 1. Emulating 3G Network Characteristics on WiFi Networks

    University essay from Linköpings universitet/Programvara och system

    Author : Alexander Alesand; [2015]
    Keywords : Emulation; Network Emulation; Network Testing; Software Testing; Testing; UMTS; 3G; Spotify; Emulering; Nätverksemulering; Nätverkstestning; Mjukvarutestning; Testning; 3G; UMTS; Spotify;

    Abstract : Mobile applications should work regardless of which type of wireless interface is used, and should be able to conceal unstable connections from the user to improve user experience. Therefore, network testing is important when developing mobile applications, but it is a challenge to reproduce network conditions when using real cellular networks since the test engineer has no control over the quality of the cellular network.

  6. 5. WCDMA Cell Load Control in a High-speed Train Scenario : Development of Proactive Load Control Strategies

    University essay from Kommunikationssystem; Tekniska högskolan

    Author : Raoul Joshi; Per Sundström; [2012]
    Keywords : WCDMA; High-speed Train; Congestion Control; Admission Control; Load Control; Cell Capacity; Cell Resource Allocation; Train Detection; Quality of Service; Dropping Fairness; Predictive Load Control;

    Abstract : Load control design is one of the major cornerstones of radio resource management in today's UMTS networks. A WCDMA cell's ability to utilize available spectrum efficiently, maintain system stability and deliver minimum quality of service (QoS) requirements to in-cell users builds on the algorithms employed to manage the load.
