    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

  3. 2. Investigating power amplifier behavior in User Equipment terminals

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

    Author : Adyasha Panda; [2021]
    Keywords : Power Amplifier; Technology and Engineering;

    Abstract : In this thesis work, experiments have been carried out to study the behavior of radio frequency power amplifier which is the one of the largest power consumers in a user equipment which is a mobile phone in this case. A CMW-500 which is a Rohde and Schwarz equipment has been used to emulate the base station. READ MORE

  4. 3. Fall detection bracelet with an accelerometer and cellular connectivity

    University essay from Uppsala universitet/Signaler och System

    Author : Ola Hammarstedt; [2019]
    Keywords : Fall detection; Accelerometer; ADXL345;

    Abstract : This thesis aims at developing a prototype for a fall detection bracelet that can connect to the cellular network. The bracelet consists of a processing unit, three sensors, a LTE USB modem and a powerbank. The prototype is aimed at elderly people since up to one out of three over the age of 65-years-old fall each year. READ MORE
