1. Antenna as a sensor for sensing available LTE networks
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)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

4. Energy harvesting from ambient WiFi energy : A method of harvesting and measuring ambient WiFi energy
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The aim of this thesis was to investigate the question of how to harvest RF energy and if we can harvest enough RF energy for it to be useful in an application. It is aimed towards sensor node applications, commonly used in a typical office environment. The WiFi band was chosen since it is omnipresent in the same environment. READ MORE

5. Impact of Time Synchronization Accuracy in Integrated Navigation Systems
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Global Navigation Satellite System/Inertial Measurement Unit (GNSS/IMU) Integrated Navigation Systems (INS) integrate the positive features of GNSS and IMU for optimal navigation guidance in high accuracy outdoor navigation systems, for example using Extended Kalman Filter (EKF) techniques. Time synchronization of IMU data with precise GNSS based time is necessary to accurately synchronize the two systems. READ MORE
