  1. 1. Radio Environment Compensation in a Narrowband IoT Positioning System : Using Radio Signal Metrics Between Stationary Devices

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Elin Berglund; [2023]
    Nyckelord :Positioning; IoT; machine learning; range estimation; Positionering; IoT; maskininlärning; avståndsuppskattning;

    Sammanfattning : The Internet of Things (IoT) has emerged as a powerful tool for meeting our need to collect information about and interact with our environments. One important aspect of this technology is positioning which imposes requirements on both the energy consumption and the arrangement of the systems. LÄS MER

  3. 2. Evaluation of Discrete-Time Wideband Receivers for NB-IoT

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Magnus Wasting; [2021]
    Nyckelord :Discrete; time; filter; NB-IoT; Charge; Sharing; CMOS; Technology and Engineering;

    Sammanfattning : A receiver that covers several RF bands requires multiple front-end filters which increases the cost in terms of components and/or board/silicon area. Front-end filters assist a receiver to withstand interference at multiples of its down-conversion frequency. LÄS MER

  4. 3. An Energy Efficient Narrowband Internet of Things Radio Base Station

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Karl Minör; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : NB-IoT was designed as an add-on to the LTE standard to enable wide area cellular connectivity to low-cost devices to facilitate the rapid growth of the Internet of Things. NB-IoT was found to increase the idle power consumption of the radio unit in an example LTE radio base station by almost 17%, costing the mobile network operator not only money, but also harming the environment through increased CO2 emissions.

  5. 4. Smart Environment - Early Wildfire Detection using IoT

    Kandidat-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Carl Hidestål; André Zreik; [2020]
    Nyckelord :Internet of Things; Wildfire; Forest fire; Narrowband-IoT; Particle detection; Technology and Engineering;

    Sammanfattning : Problems with extreme weather, such as drought, has increased due to greenhouse emissions. As one of the consequences to this, forest fires have emerged more frequently on a global level. This became obvious in Sweden, in the summer of 2018, which has been stated to have been the worst affected year of forest fires in modern time. LÄS MER

  7. 5. A Linear, Wide-band, Low-Power Receiver for Narrowband- Internet of Things (NB-IoT)

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Rohan Raghunath; Ghanashyam Ravindranath Prabhu; [2018]
    Nyckelord :NB-IoT; FTNC; Harmonic rejection; N-path filtering; RX Front End; Low power; Wide-band; Passive mixer; Current mode; Technology and Engineering;

    Sammanfattning : Advancement of technology with the aid of new application, wireless communication has grown rapidly in the past two decades. Recently, in the wireless communication industry, Narrowband- Internet of Things (NB-IoT) is being discussed by everyone, as the most important emerging technology of the day. LÄS MER
