“…Each of the exponentially decaying spectrum is treated as a unit to build the entire channel and called a cluster [72], [73]. The PDP shape has been reported in the microwave frequency band originally, and the same shape was also found applicable at the mm-wave band [74]- [76]. A simplified shape model yields the tapped delay line model, e.g., as reported for indoor rooms [77] at 62 GHz and outdoor fixed links [33], [78] around 30 GHz.…”

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.

“…The susceptibility of mm wave links to blockage due to their weak diffraction characteristics is well known [23], [34], and the effect of human movement is investigated in [35], [36], but their impact on the network performance has not been studied previously. Many deterministic and statistical mm wave propagation models have been proposed based on channel measurement studies [25], [30], [37], but many of these focus on omnidirectional transmission (and possibly directional reception). Reference [38] provides line of sight (LOS)/ non-line of sight (NLOS) channel models developed by the IEEE 802.15 TG3c group for indoor WPAN environments.…”

Abstract-We present a cross-layer modeling and design approach for multiGigabit indoor wireless personal area networks (WPANs) utilizing the unlicensed millimeter (mm) wave spectrum in the 60 GHz band. Our approach accounts for the following two characteristics that sharply distinguish mm wave networking from that at lower carrier frequencies. First, mm wave links are inherently directional: directivity is required to overcome the higher path loss at smaller wavelengths, and it is feasible with compact, low-cost circuit board antenna arrays. Second, indoor mm wave links are highly susceptible to blockage because of the limited ability to diffract around obstacles such as the human body and furniture. We develop a diffraction-based model to determine network link connectivity as a function of the locations of stationary and moving obstacles. For a centralized WPAN controlled by an access point, it is shown that multihop communication, with the introduction of a small number of relay nodes, is effective in maintaining network connectivity in scenarios where single-hop communication would suffer unacceptable outages. The proposed multihop MAC protocol accounts for the fact that every link in the WPAN is highly directional, and is shown, using packet level simulations, to maintain high network utilization with low overhead.

“…The 60 GHz band and the 70 GHz as well as 80/90 GHz frequency bands [15], [82] have also attracted much attention. Based on these measurements, channel models have been produced for several mmWave bands in [6], [7], [14], [27], [69], [76], [77], [98], [103], [120], [125], [167]. We commence by presenting the early stages of mmWave narrow-band channel characterization studies an then we proceed to specifying the recent advancements on the wideband mmWave channel models.…”

“…The spatio-temporal characteristics of the 60 GHz channel were also studied in [14], [28], [66], [69], [120], [121], [125], [142], [166], [175], [206], where the model of the indoor 60 GHz channel is based on the TSV [67] and on the extended-SV [171], [172] channel models. The general double-directional wideband CIR is given by:…”

Abstract-The millimeter wave (mmWave) frequency band spanning from 30 GHz to 300 GHz constitutes a substantial portion of the unused frequency spectrum, which is an important resource for future wireless communication systems in order to fulfill the escalating capacity demand. Given the improvements in integrated components and enhanced power efficiency at high frequencies, wireless systems can operate in the mmWave frequency band. In this paper, we present a survey of the mmWave propagation characteristics, channel modeling and design guidelines, such as system and antenna design considerations for mmWave, including the link budget of the network, which are essential for mmWave communication systems. We commence by introducing the main channel propagation characteristics of mmWaves followed by channel modeling and design guidelines. Then, we report on the main measurement and modeling campaigns conducted in order to understand the mmWave band's properties and present the associated channel models. We survey the different channel models focusing on the channel models available for the 28 GHz, 38 GHz, 60 GHz and 73 GHz frequency bands. Finally, we present the mmWave channel model and its challenges in the context of mmWave communication systems design.
