“…A seminal work [188] mentions that a basic propagation mechanism of the measured 40 and 60 GHz outdoor channels is similar, while the fading statistics are different from microwave mobile links due to fewer multipaths. Reported comparisons of channel characteristics at the mm-wave bands cover pathloss and delay spread with those measured at 2 GHz in office rooms [189], [190], 5 GHz in halls and meeting rooms [191], [192], 6.5 GHz in a car compartment [62], 17 GHz in an office building [193], [194] and in a car compartment [195], and finally with ultrawideband indoor channels [196], [197]. Comparison of channel characteristics parameters for different mm-wave frequency bands is reported in [27] for outdoor 38 and 60 GHz channels, [90] for indoor 60 and 70 GHz channels, and [21], [28] for 28 and 73 GHz in urban cellular channels.…”

SUMMARYMillimeter-wave (mm-wave) radio is attracting attention as one of the key enabling physical layer technologies for the fifthgeneration (5G) mobile access and backhaul. This paper aims at clarifying possible roles of mm-wave radio in the 5G development and performing a comprehensive literature survey on mm-wave radio channel modeling essential for the feasibility study. Emphasis in the literature survey is laid on grasping the typical behavior of mm-wave channels, identifying missing features in the presently available channel models for the design and evaluation of the mm-wave radio links within the 5G context, and exemplifying different channel modeling activities through analyses performed in the authors' group. As a key technological element of the mm-wave radios, reduced complexity beamforming is also addressed. Design criteria of the beamforming are developed based on the spatial multipath characteristics of measured indoor mm-wave channels.

“…Indoor wireless channels are currently served over 2.4 GHz, 5 GHz WiFi, and 60 GHz WiGig frequency bands, commonly used for short-range indoor communications. The vast available bandwidth (6 GHz) in the 60 GHz mmWave band has motivated extensive 60 GHz indoor propagation measurements to understand channel characteristics for designing WLAN systems, capable of achieving multi-gigabits-persecond throughputs [6]- [8]. Highly directional horn antennas have also been placed at the TX to overcome the additional 15 dB/km of atmospheric attenuation, while reducing inter-cell interference [6].…”

Abstract-This paper presents 28 GHz and 73 GHz millimeterwave propagation measurements performed in a typical office environment using a 400 Megachip-per-second broadband sliding correlator channel sounder and highly directional steerable 15 dBi (30• beamwidth) and 20 dBi (15 • beamwidth) horn antennas. Power delay profiles were acquired for 48 transmitter-receiver location combinations over distances ranging from 3.9 m to 45.9 m with maximum transmit powers of 24 dBm and 12.3 dBm at 28 GHz and 73 GHz, respectively. Directional and omnidirectional path loss models and RMS delay spread statistics are presented for line-of-sight and non-line-of-sight environments for both co-and cross-polarized antenna configurations. The LOS omnidirectional path loss exponents were 1.1 and 1.3 at 28 GHz and 73 GHz, and 2.7 and 3.2 in NLOS at 28 GHz and 73 GHz, respectively, for vertically-polarized antennas. The mean directional RMS delay spreads were 18.4 ns and 13.3 ns, with maximum values of 193 ns and 288 ns at 28 GHz and 73 GHz, respectively.Index Terms-Millimeter-wave; 28 GHz; 73 GHz; indoor propagation; indoor environment; path loss; RMS delay spread; close-in free space reference model; polarization.

“…General investigations of the frequency dependence of radio wave propagation effects are presented in McDonnell []. In Nobles and Halsall [] and Droste and Kadel [], path loss and wideband characteristics are measured at 17 and 60 GHz, respectively. Measured data and empirical models for 2.5 and 60 GHz in‐building propagation path loss and multipath delay spread are presented in Anderson and Rappaport [].…”

Experimental comparison between centimeter‐ and millimeter‐wave ultrawideband radio channels

This paper analyzes radio wave propagation phenomena at two very different frequency bands: 2-10 GHz (centimeter wave) and 57-66 GHz (millimeter wave (mm-W)). The two frequency bands have been measured using the same equipment and under similar propagation conditions, such as path loss, root-mean-square delay spread, maximum excess delay, and Rician K factor, and their respective correlations compared. Obstructed line of sight situations have also been considered by using metal and cardboard obstructions. The statistical distributions, main specular reflections, and decay factors have been found similar for the two bands. However, the measured path loss, correlation in terms of electrical distances, and the K factor are higher for the millimeter-wave frequency band. Indeed, the importance of propagation mechanism changes from one band to the other, which must be considered in the design of future mm-W systems.
