Research on Reliable Low-Power Wide-Area Communications Utilizing Multi-RAT LPWAN Technologies for IoT Applications
Štůsek, Martin ; Grochla, Krzysztof (oponent) ; Curado, Marilia (oponent) ; Hošek, Jiří (vedoucí práce)
This doctoral thesis addresses the “Research on Reliable Low-Power Wide-Area Communications Utilizing Multi-RAT LPWAN Technologies for IoT Applications”. Despite the immense progress in massive Machine-Type Communication (mMTC) technology enablers such as Low-Power Wide-Area (LPWA) networks, their performance does not have to satisfy the requirements of novelty Internet of Things (IoT) applications. The main goal of this Ph.D. work is to explore and evaluate the limitations of current LPWA technologies and propose novel mechanisms facilitating coverage planning and assessment. Proposed frameworks are fine-tuned and cross-validated by the extensive measurement campaigns conducted in public LPWA networks. This doctoral thesis further introduces the novelty approach of multi-RAT LPWA devices to overcome the performance limitation of individual LPWA technologies. The current implementation primarily focuses on diminishing the greatest multi-RAT solutions disadvantage, i.e., increased power consumption by employing a machine learning approach to radio interface selection.

Universal Multi-Rat Tester For Mmtc Applications
Juráň, Radovan ; Možný, Radek
While the IoT has made significant progress along the lines of supporting its individualapplications, there are many massive Machine-Type Communication (mMTC) scenarios in which theperformance offered by any single Radio Access Technology (RAT) available today might be insufficient.To address these use cases, we introduce the concept of multi-RAT tester, which implies theavailability and utilization of several RATs within a single IoT device. We begin by offering insightsinto which use cases could be beneficial and what the key challenges for mMTC implementation are.We continue by discussing the potential technical solutions and employing our own prototype of amulti-RAT device capable of using different Low-Power Wide-Area (LPWA) communication technologies.It is assumed that use of multiple radios simultaneously will lead to overall improvementof communication parameters by leveraging the synergy between RATs. The novel vision enabledby the multi-RAT concept in this work could be impactful across multiple fields and calls for crosscommunityresearch efforts in order to adequately design, implement, and deploy future multi-RATmMTC solutions.
