Characterization of the indoor radio environment (RE) is a prerequisite for advances in the design and optimization of next-generation indoor wireless networks and for the construction of a digital twin of the building. The need for comprehensive and accurate indoor characterization will be evident in the future hyper-connected mixed real-virtual …
In this doctoral thesis, radio signal propagation in special environments is discussed. The primary focus is on the development of a path loss model for radio signal propagation in long road tunnels and underground passageways, which allows a rather precise calculation of radio signal path loss and, consequently, a quick …
