E-band millimeter wave indoor channel characterization

Abstract

Abstract-This paper presents the channel characterization of indoor environments in the E-Band (80.5-86.5 GHz). Measurements were performed by means of mechanical steering of directive antennas at both the transmitter and receiver side, allowing a double-directional angular characterization. Specular components have been estimated by means of a detection algorithm. Characterization of the path loss, delay spread, Angle-ofDeparture and Angle-of-Arrival spreads are presented for two indoor environments.

An Indoor Channel Model for High Data-Rate Communications in D-Band

“…It is known that for LOS conditions, the majority of the multipath appears from the LOS path and first order reflections over large surfaces. Our results are comparable with the ones presented in [18], [31], [32] where a maximum of 6 clusters were obtained at 60 GHz and of 4 clusters at 73 GHz and 80.5-86.5 GHz for indoor/outdoor scenarios. Furthermore, 2 -5 clusters were obtained at 28 GHz only for indoor channel measurements [33].…”

“…In this section, we compare the results obtained in D-band with those previously obtained in the V (59 -65 GHz) and E (80.5 -86.5 GHz) bands considering the Indoor 3 scenario [18].…”

“…where α k , τ k , T k , R k represent the amplitude, delay, angle of departure and angle of arrival of the kth multipath component (MPC), respectively. The MPCs were extracted from the bidirectional channel measurements by synthetizing the omnidirectional Power Angular Delay Profile (PADP) [17], [18]. the distance in between the antennas is of 1.8m, is equal to 0 • at the receiver side and the Azimuth angle at the transmitter side is 0 • .…”

“…Other studies have also been done at mm-Wave frequencies (IEEE 802.15.3c [1], IEEE 802.11ad [3]) that are based on the extended time-angular S-V model and considered that the model is cluster based. At the same time, we wanted to also be able to compare our results with the ones presented in [18] that are part of the mmMagic initiative [6] and that used the same approach to characterize their measurements. In this article, blocking scenarios from humans, doors and partitions were also considered.…”

“…In Section III, the channel characteristics and model are provided for both LOS and NLOS scenarios. Section IV compares the measured channel characteristics with those obtained in the E and V bands under the same environment conditions [18], as well as with other mm-Wave indoor models. Finally, Section V concludes the paper and gives an outlook for future works.…”
