D-band Channel Measurements and Characterization for Indoor Applications

Abstract

This paper presents measurements and characteriza5 tion of D-band indoor channels. The measurements are performed 6 in line-of-sight (LoS), obstructed-LoS (OLoS), and reflected non7 LoS (RNLoS) environments. For OLoS sceanrio, cylindrical 8 objects of different materials are used as an obstruction. For 9 RNLoS, different surfaces are used as reflectors. From the large 10 set of LoS and OLoS measured data, the parameters for single11 slope path loss model with shadowing are devised. Furthermore, 12 the analysis of multipath propagation is performed. The results 13 show that strong multiple reflections from the transmitter and 14 receiver electronics are present both in LoS and OLoS envi15 ronments. Additionally, the results show that glass and ceramic 16 objects in the propagation path produce surface-diffracted rays 17 which clock-wise and counter clock-wise superposition leads to 18 frequency-dependent path loss. Finally, the results show that the 19 RNLoS measured path loss with aluminum plate as a reflector is 20 very similar to free-space path loss when the angle of incidence 21 and the angle of reflection are equal. 22
