    Author : Barath Kumar Sathish Kumar; [2022]
    Keywords : Radio Frequency energy harvesting; Antenna as a sensor; Long-Term Evolution; Rectifier; Printed Circuit Board; Altium Designer; Matching network; Voltage multiplier; Schottky diodes; Multiband LTE antenna; Ambient energy harvesting; Low power Internet of Things; Wireless power transfer; Radiofrekvensenergiskörd; Antenn som sensor; LTE; Likriktare; Printed Circuit Board; Altium Designer; Matchande nätverk; Spänningsmultiplikator; Schottky-dioder; Multiband LTE-antenn; Omgivande energiskörd; Lågeffekt Internet of Things; Trådlös kraftöverföring;

    Abstract : This thesis primarily deals with the concept of designing an antenna based device to harvest energy from Radio Frequency (RF) and using the harvested energy to sense the available Long Term Evolution (LTE) network in order for the Internet of Things (IoT) devices to connect to the network for the purpose of transmitting and receiving data. Secondarily the importance of this project is targeting how to conserve battery power in an IoT device and extend it’s lifetime. READ MORE

  2. 2. Characterisation and Modeling of RF environment

    University essay from Uppsala universitet/Signaler och system

    Author : Patric Beas Petersson; [2022]
    Keywords : signal processing; passive radar; antenna array; data processing; signalbehandling; passiv radar; antennarray; databehandling;

    Abstract : Devices that transmit and receive electromagnetic signals are today central to the way people communicate and acquire information from the surroundings. WiDAR, Wideband Digital Array Receiver, is the name of a new system of digital antenna array receivers, which has recently been developed at Saab in Järfälla and is the focus of this thesis.

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

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

    Author : Karl Minör; [2020]
    Keywords : Technology and Engineering;

    Abstract : 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.

  4. 4. Improved Precision Time Protocol with Relative Clock Phase Information

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Avneesh Vyas; [2020]
    Keywords : ;

    Abstract : A common time reference among nodes is one of the key requirements in telecommunication, distributed control systems and industrial automation systems. For instance, 3GPP LTE TDD standard requires at least ± 1.5 µsec time accuracy among base stations in order to resolve uplink and downlink transmission. READ MORE

  5. 5. Design of Cellular and GNSS Antenna for IoT Edge Device

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi
