“…Several other authors [10][11][12][13][14][15][16][17][18][19][20] performed extensive channel sounding experiments for millimeter wave channels in case of indoor communication environments, calculated the channel impulse response, and characterized the path loss for the different transmitter and receiver separations, human blockage, obstructions in the form of walls, cabinets, and furniture. Authors in [11] also considered polarimetric diffuse scattering channel model and recorded the channel measurements at 26 GHz and 60 GHz.…”

“…As the indoor environment can have several rough surfaces and edges, and when the signal impinges on these surfaces scattering will take place, the authors explored the polarimetric diffuse scattering channel measurements. Phased arrays were utilized by the authors in [12] to estimate the ray paths with the knowledge of beam patterns of the phased arrays. Authors also performed ray-tracing simulation to verify the results at mm-wave frequencies.…”

In this paper, we developed a 3-dimensional (3D) ray-tracing simulator using MATLAB for establishing the viability of heating, ventilation, and air conditioning (HVAC) ducts as a reliable communication channel for indoor communication at millimeter-wave (mm-wave) frequencies. We present theoretical analysis of image theory ray-tracing and provide the equations for total electric field due to different rays undergoing reflections at the duct walls. We also computed the received signal strength indicator (RSSI) for the dry and moisture-laden air flowing through the HVAC ducts. The ray-tracing results are compared with the experimental and theoretical results we obtained for the HVAC ducts. With transmitter effective isotropic radiated power (EIRP) of 7 dBm, we obtain RSSI which varies between −34 dBm and −53 dBm for dry atmospheric pressure and temperature of 1013.25 hPa and 294.26 K, respectively, and duct lengths of up to 8 m at 60 GHz.
