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

Abstract

This paper proposes a measurement based modeling of D-band indoor channels. Different indoor environments were considered including Line-of-Sight (LOS) and Non Line-of-Sight (NLOS) conditions. Double steering at the transmitter and receiver sides was performed allowing angular characterization of the channel. Path loss, delay spread, angular spread, intra-and inter-cluster characteristics were also modeled. These characteristics were then compared to the ones obtained in other millimeter wave bands for the same environment.

Technology Roadmap for Beyond 5G Wireless Connectivity in D-band

“…A fine characterization is required for realistic evaluation of new sub-THz behavior. Only few channel sounding campaigns, complex and costly, have been published yet [11] [12]. They are complemented by convenient numerical prediction, and produce on-demand channel models.…”

Performance study of path loss models at 14, 18, and 22 GHz in an indoor corridor environment for wireless communications

“…HE availability of a tremendous frequency spectrum is at the head of the reasons for achieving extremely high-speed communication services. Hence, the vital resource and the access factor for the fifth-generation mobile system (5 ) and any other mobile access networks are quantity, quality, and efficiency of using the amount of the available spectrum [1], [2].…”

“…Accordingly, this lack of bandwidth will not meet the aspirations of the upcoming 5 wireless system to accomplish high peak data transmission rates up to multi gigabits per second even with complex modulation schemes and multiple-input multiple-output (MIMO) systems [1]- [13]. Because of that and due to the rapid growth in demand for much higher data rates, the research on the millimeter-wave (mmWave) frequency spectrum (30-300 GHz) has been accelerated for the reason that these bands are the candidate for deployment of the 5 cellular network and for satisfying future needs [2], [4]- [7].…”

Angular characteristics of multipath propagation in an indoor industrial environment

“…However, the effective directionality of a system depends not only on the antenna system, but also on the considered environment [20]. Hence, the directions of arrival of the MPCs have been investigated in various indoor environments [21][22][23][24][25][26][27][28][29]. The cross-polarized signals exhibit similar power levels for all elevation angles, while co-polarized signals appear in clusters in the azimuthal plane [21].…”
