60-GHz Millimeter-Wave Pathloss Measurements in Boise Airport

This paper presents a large scale fading channel model at the 60 GHz band. This model is based on the measurement campaign that our team conducted at Boise Airport and Boise State University. The close-in reference path loss and floating-intercept path loss models with both statistical and stochastic approaches are investigated for these environments. The measurements were collected at several different locations in line-of-sight (LOS) and non-line-of-sight (NLOS) scenarios using high gain directional antenna. The path loss exponent and shadowing factor are determined based on the measurement results and compared with recent work at this frequency. Both the stochastic gradient descent algorithm and the statistical least-square technique are used to analyze the floating-intercept path loss model. The results show that the path loss exponents in the outdoor scenarios are higher than the indoor environment due the RF noise caused by the sunny and dry climate in the Boise area. Finally, a good agreement is found between the measurement results and the prior work results in presented in the literature.
