  1. 1. Saving Energy in Cellular IoT using Low-Power Wake-up Radios

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

    Author : Ratna Pavan Kumar Ponna; Dripta Ray; [2018]
    Keywords : Technology and Engineering;

    Abstract : The thesis work is based on power saving techniques to enhance the battery life of Machine Type Communication devices. The basic principle behind the introduced methods to save energy is to allow the Machine Type Communication devices only to perform its activities for a short time and go to sleep or inactive mode for rest of the time.

  3. 2. Impact of Extended DRX Cycles on Battery Lifetimes and UE Reachability

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Vignesh Cholaraju Narasaraju; [2016]
    Keywords : LTE; MTC; Machine-Type-Communication; SFN; DRX; eDRX; Extended DRX; Idle Mode; Paging; M2M; Machine-to-Machine; IoT; Internet-of-Things;

    Abstract : Several UE energy consumption optimization techniques have been proposed for Machine Type Communication (MTC) devices. Extended Discontinuous Reception (eDRX) in idle mode is one such technique wherein an UE in idle mode wakes up only during its Paging Occasion (PO) to monitor paging messages from eNodeB (eNB).

  4. 3. A LTE UPCUL architecture design combining Multi-Blackboards and Pipes & Filters architectures

    University essay from Blekinge Tekniska Högskola/Institutionen för programvaruteknik

    Author : Bohui Jiang Axelsson; [2015]
    Keywords : Multi-Blackboards; Pipes Filters; LTE 4G; Ericsson;

    Abstract : Context. The single blackboard architecture is widely used in the LTE application area. Despite its several benefits, this architecture limits synchronization possibilities of the developed systems and increases the signal operational latency. As a result the DSP (Digital Signal Processing) utilization is suboptimal. READ MORE

  5. 4. How to Cut the Electric Bill in Mobile Access Networks: A Mobile Operator's Perspective

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Konstantinos Chatzimichail; [2014]
    Keywords : ;

    Abstract : One of the major challenges that mobile operators are facing is the increasing power consumption costs as a consequence of the network densication experienced in current and future mobile access networks. This power increase causes both financial and environmental concerns to operators, since both the operational expenses and the CO2 emissions are affected. READ MORE
