Characterization of millimeter wave propagation in indoor office environments

For the last few decades, the millimeter wave frequency band (30–300 GHz) has been seen as a serious candidate to host very high data rate communications. In order to design the next-generation (5G and beyond) radio communication systems, it is prerequisite to properly model the radio propagation channel and to know the electromagnetic properties of different materials in this frequency band. This work presents some measurements carried out in a typical office environment at 28 GHz, with the aim of analyzing the main propagation mechanisms and characterizing the electromagnetic properties of some common construction materials.
