Propagation Measurements and Modeling with Transparent Reflectors at Sub-6 (3.6-6 GHz) and mmWave (28 GHz) in Indoor Environments, BWAC Core Project
Project runs from 10/01/2021 to 09/30/2022
In this project, channel sounding measurements will be conducted for 3.6 GHz and 28 GHz bands. USRP N310 with GNU radio setup will be used for the former, and NI PXIe-1085 TX/RX chassis will be used for the latter. Measuring the power angular-delay profile of the channel that includes angle-of-departure and angle-of-arrival of the multipath components (MPCs) is also possible with NI PXIe-1085 equipment. Sekisui smart reflectors will be placed on various backgrounds, e.g. glass, drywall, concrete. Experiments will be repeated for two different reflector shapes, i.e. planar and cylindrical. In the experiment setup, reflector and the transmitter will be fixed, whereas the receiver will move on a circular path for pattern characterization, and on a linear path for loss calculations. Initial assumption about this reflector is that it promotes diffuse scattering to enrich the multipath environment. This reflector is also transparent that is to address cosmetic issues.
