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

3. An Energy Efficient Narrowband Internet of Things Radio Base Station
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : 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. Improved Precision Time Protocol with Relative Clock Phase Information
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)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
