  1. 11. Design of Cellular and GNSS Antenna for IoT Edge Device

    Magister-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Ioannis Broumas; [2019]
    Nyckelord :IoT; Internet of Things; Edge device; LTE; 4G; LTE-M1; Antenna; Antenna System; Narrow Band IoT; NB-IoT; Plannar Antennas; GPS; PCB; multiband antenna;

    Sammanfattning : Antennas are one of the most sensitive elements in any wireless communication equipment. Designing small-profile, multiband and wideband internal antennas with a simple structure has become a necessary challenge. LÄS MER

  3. 12. Virtualizing LoRa baseband functionalities to the Edge

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

    Författare :Patrik Vijayendra Walvekar; [2019]
    Nyckelord :;

    Sammanfattning : Traditional network architecture design of Low Power Wide Area Networks (LPWAN) suffer from their inability to dynamically scale resources based on the incoming traffic and involve manual procedures for capacity upgrades. There is a need to develop a cloud-native architecture where the gateway hardware performs signal detection while baseband processing is virtualized in the Edge, provisioning for dynamic scaling of resources.

  4. 13. Phase Locked Loops in Fully Integrated NB-IoT Transceivers

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

    Författare :Adam Waks; [2018]
    Nyckelord :Phase locked loops; Narrow Band Internet of Things; Frequency pulling; Balun; Inductor; Technology and Engineering;

    Sammanfattning : This thesis investigates how to fulfill the Narrow Band - Internet of Things (NB-IoT) specification for a fully integrated transceiver in the phase locked loop's (PLL) perspective. Designing a fully integrated transceiver, integrating a power amplifier (PA) is challenging as it leads to frequency pulling of the voltage controlled oscillator (VCO) in the PLL, deteriorating the performance.

  5. 14. IoT for fresh water quality monitoring

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

    Författare :Duarte Maher; [2018]
    Nyckelord :IoT; Machine Learning; Water Quality Monitoring; iWater; IoT; Maskininlärning; Vattenkvalitetsövervakning; iWater;

    Sammanfattning : Water is one of the most important resources in the world. It has direct impact on the daily life ofmankind and sustainable development of society. Water quality affects biological life and has to obeystrict regulations. Traditional water quality assurance methods, used today, involve manual samplingfollowed by laboratory analysis. LÄS MER

  7. 15. Smart City Lighting in the City of Stockholm

    Master-uppsats, KTH/Nätverk och systemteknik

    Författare :Ignacio Javier Pascual Pelayo; [2018]
