Millimeter Wave Propagation Measurements and Modeling in Hospital Environments Thesis Instructor: Title: Millimeter Wave Propagation Measurements and Modeling in Hospital

and Technology aalto university school of science and technology abstract of the master's thesis Applications of wireless technologies in medical treatments have been considered for realizing portable medical equipment and remote monitoring. The 60 GHz band can theoretically oer very high data rates for such applications, but the propagation characteristics of hospital environments have not been studied. Based on preliminary measurements in a shielded room, the propagation characteristics can be expected to be dierent compared to regular indoor environments. As a part of a feasibility study of 60 GHz radio systems, propagation channel measurements were performed in two dierent hospital environments, an angiog-raphy room and an ultrasonic inspection room. In this work, path loss and delay domain analysis were made based on the measurement data. Obtained power delay proles were used to develop delay domain channel models. The path loss of both hospital environments was found to be similar to common indoor environments. However, the delay domain characteristics of the two rooms turned out to be quite dierent from each other. Based on this, dierent models were developed for the environments. ympäristöille kehitettiin oma kanavamalli. 4 Preface I would like to thank my instructor, Mikko Kyrö and my supervisor, Pertti Vainikainen for all the helpful advice. Thanks to my unocial supervisor, Katsuyuki Haneda for all of his help and for getting me involved in this project. Thanks to the Radio Laboratory in general for giving me the opportunity to work there for the past year. Also thanks to my family for all the support and understanding during the work.
