1. The sounds of radio : on radio as an auditive means of communication
Abstract : The primary purpose of this doctoral thesis is to present a theoretical framework for analysis of communication through radio, taking the sounding dimension of the medium as a primary characteristic. My theoretical approach is manifold, but I explicitly use writings from the field of ethnomethodology/microsociology (linguistic communication) of Alfred Schutz (sociology of everyday life) and Gerhard Maletzke (mediated communication).

2. Impulse Radio UWB for the Internet-of-Things : A Study on UHF/UWB Hybrid Solution
Abstract : This dissertation investigates Ultra-Wideband (UWB) techniques for the next generation Radio Frequency Identification (RFID) towards the Internet-of-Things (IoT). In particular, an ultra-high frequency (UHF) wireless-powered UWB radio (UHF/UWB hybrid) with asymmetric links is explored from system architecture to circuit implementation. READ MORE

3. Wireless Sensor Network and Radio Wave Propagation in Harsh Environments
Abstract : This licentiate thesis cover two important subjects regarding the application of wireless sensor networks (WSNs). Both subjects are related to propagation mechanisms. The first subject is what the radio channel looks like and how it behaves. READ MORE

4. Model-Based Cognitive Radio Strategies
Abstract : Many frequency bands for wireless services are severely underutilized by the primary users (PU) to which these bands are assigned. This motivates a new class of wireless communication devices known as cognitive radios (CR), which identify vacant spectrum and transmit accordingly. READ MORE

5. Towards Secure Synchronous Communication Architectures for Wireless Networks
Abstract : The vision behind the Internet of Things (IoT) revolves around creating a connected ecosystem where devices, people, and systems collaborate seamlessly, unlocking new possibilities, improving efficiency, and enhancing our daily lives. IoT encloses many device classes, including low-power wireless devices that rely on batteries or energy harvesting. READ MORE
