    Sammanfattning : Long Term Evolution (LTE) known in the market as 4G LTE, it is an evolution of the GSM/UMTS standard. The overall aim of LTE was to provide a new radio access technology focusing on packet-switched data only. LTE has provided a new peak download rates, low data transfer latencies, and improved the support for mobility. LÄS MER

  3. 2. Energy Efficient Analysis for WCDMA/ 3G Homogeneous and Heterogeneous Deployments in Indoor Environment

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Ahmad Moeed Aslam; [2012]
    Nyckelord :;

    Sammanfattning : In near future, the cellular traffic will increase rapidly with majority of the increase coming from Indoor traffic. To cope up with the ever increasing demand, more Base Stations are being deployed in limited areas, which can increase the capacity but will also be responsible for increased energy consumption.

  4. 3. Energy Consumption in Location Sharing Protocols for Android Applications

    Master-uppsats, Programvara och system; Tekniska högskolan

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

    Sammanfattning : 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.
