Power Azimuth Spectrum Measurements in Home and Office Environments at 62.4 GHz

The high demand for unlicensed spectrum mandates the use of higher frequencies, such as the 60 GHz band, where large amounts unlicensed bandwidth exists. In this paper, the results from Power Azimuth Spectrum (PAS) measurements in a home and an office environment are presented with a view of revealing the amount of scattering power at that frequency and its relative power to the Line-of-Sight (LoS) signal. Moreover, a tractable scheme is proposed for the estimation of the Power Azimuth Spectrum from absolute power measurement data which produces a very close fit with the measured PAS. A discussion is made on the accuracy of this method which is dependent on the directionality of the antenna elements, the fading in the channel and the presence of noise.
