  1. 11. 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.

  5. 14. Performance Evaluation of Packet Scheduling Algorithms for LTE Downlink

    University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Author : Ömer Arslan; Olufemi Emmanuel Anjorin; [2012]
    Keywords : LTE; 3GPP; OFDMA; Downlink Scheduling; CQI;

    Abstract : Long Term Evolution (LTE) of the Universal Mobile Telecommunications System (UMTS) is designed to revolutionize mobile broadband technology with key considerations of higher data rate, improved power efficiency, low latency and better quality of service. It promises high peak data rates of 100 Mbps downlink and 50 Mbps uplink transmissions and can operate in different bandwidths ranging from 1. READ MORE

  6. 15. Energy Consumption in Location Sharing Protocols for Android Applications

    University essay from Programvara och system; Tekniska högskolan

    Author : Mihails Prihodko; [2012]
    Keywords : Message Queuing Telemetry Transport; location sharing; Android; energy consumption; 3G networks; UMTS WCDMA;

    Abstract : This thesis studies the Message Queue Telemetry Transport protocol (MQTT) as an application layer protocol in geographical location sharing applications using third generation cellular communication (3G). The MQTT protocol is compared in terms of energy efficiency and amount of data generated with the Hypertext Transfer Protocol (HTTP), which is currently used in typical location sharing applications.
