“…Increasing the carrier frequency above 6 GHz and up to mmwave bands leads to higher free-space pathloss (20 dB at factor 10 frequency increase) with isotropic antennas [35], higher penetration and diffraction losses [52], and more severe shadow fading [53]. The net result seems to be a reduction in the number of active scatterers [54], i.e., a sparsification of the channel.…”

Abstract-Downlink beamforming in Massive MIMO either relies on uplink pilot measurements-exploiting reciprocity and time-division duplexing (TDD) operation, or on the use of a predetermined grid of beams with user equipments reporting their preferred beams, mostly in frequency-division duplexing (FDD) operation. Massive MIMO in its originally conceived form uses the first strategy, with uplink pilots, whereas there is currently significant commercial interest in the second, gridof-beams. It has been analytically shown that with isotropic scattering (independent Rayleigh fading) the first approach outperforms the second. Nevertheless, there remains controversy regarding their relative performance in practical channels. In this contribution, the performances of these two strategies are compared using measured channel data at 2.6 GHz.

“…In higher frequency bands, the material characteristics of the building have a major impact on defining the penetration loss pattern, which means that the value of Lmaterial(fc) can be significantly different for different buildings. Further discussion on the impact of fc on the wall penetration loss can be found for example in [10], [13] and [17]- [19]. Furthermore, the impact of different wall materials has been discussed in [10] and [17]- [23].…”

Recently introduced 5G micro operator concept aims at providing high-quality mobile services in specific highdemand (indoor) locations to complement the coverage and capacity offered by the traditional mobile network operators (MNOs). For reliable service delivery, micro operators need local spectrum access rights with predefined levels of quality guarantees. This can be obtained via granting spectrum micro licenses, where the license areas can be the different buildings. To coordinate the interference between the micro operators themselves and potential incumbent spectrum users, accurate interference characterization between the involved systems is a necessity. This requires proper modeling of the radio wave propagation characteristics, which is currently missing for micro operator deployment scenarios in their target frequency bands. This paper introduces a new propagation model for evaluating the interference between neighboring micro operators located inside different buildings. The proposed model is based on a number of sub-models and components, and the basis for each of the components has been taken by selecting appropriate path loss models described in the literature. In all, the introduced propagation model is valid for deployments in different frequency bands, and for various types of buildings and outdoor environments surrounding the buildings with micro operator deployments.

“…In mm-wave frequency spectrum and especially the V-band (40 − 75 GHz), most of the available research studies in the literature focused at evaluating reflection and transmission characteristics of common building materials at 60 GHz [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. For the same purpose, only a small number of research investigations tapped 70 GHz frequency band [9,[26][27][28][29][30][31]33]. [25] reviews the literature for penetration loss and electromagnetic properties of common building materials at mm-Wave frequencies.…”

Wireless backhauling at 70 GHz maybe a viable option for 5G small cells densification. Whether indoors or outdoors, the millimeter-wave (mm-wave) backhaul links in an obstructedline-of-sight (OLOS) or a non-LOS (NLOS) condition require a thorough investigation on reflection and transmission losses caused by various objects in the environment. In this paper, we evaluate the reflection and transmission loss due to linkobstructing objects at 70 GHz frequency band, ranging from human body to various building materials and vegetation. For this purpose, we employed a free-space wideband mm-wave channel sounding setup in the anechoic chamber and outdoors.The results indicate that building materials, human beings and trees cause significant attenuation of the 70 GHz radio signals, which is on average 45 − 50 dB. On the other hand, building materials such as, windows, and laminated or painted plywood, medium-density fiberboard and plasterboard are good reflectors. This extends an opportunity of establishing stable communication links through reflections from the materials in NLOS conditions using beamforming.
