This paper describes a measurement campaign performed in a modern building at the University of L’Aquila, Italy. Measurements are taken for two large bands around 60 GHz, i.e. 54-59 and 61-66 GHz. The channel probe is an ultrawideband (UWB) PN-sequence signal having a bandwidth of 1.2 GHz, which is up-converted to the 60 GHz band and finely tuned in order to span the whole mentioned bands. Measurements were done at several different locations, in line-of-sight and non-line-of-sight scenarios and using different combinations of transmitting and receiving antennas: either omnidirectional or directional antennas with a beam width of 30 or 9 degrees, respectively. Accurate processing of recorded signals and subsequent regression fits allow us to derive path loss models that include both distance and frequency dependence of the power decay. The path loss is modeled as the product of a distance dependent term and a frequency dependent term, both modeled through power laws. Our analysis shows that the parameters of the path loss models for 60 GHz channels in modern buildings assume values comparable to UWB channels.

Abstract

This paper describes a measurement campaign performed in a modern building at the University of L’Aquila, Italy. Measurements are taken for two large bands around 60 GHz, i.e. 54-59 and 61-66 GHz. The channel probe is an ultrawideband (UWB) PN-sequence signal having a bandwidth of 1.2 GHz, which is up-converted to the 60 GHz band and finely tuned in order to span the whole mentioned bands. Measurements were done at several different locations, in line-of-sight and non-line-of-sight scenarios and using different combinations of transmitting and receiving antennas: either omnidirectional or directional antennas with a beam width of 30 or 9 degrees, respectively. Accurate processing of recorded signals and subsequent regression fits allow us to derive path loss models that include both distance and frequency dependence of the power decay. The path loss is modeled as the product of a distance dependent term and a frequency dependent term, both modeled through power laws. Our analysis shows that the parameters of the path loss models for 60 GHz channels in modern buildings assume values comparable to UWB channels.
