“…Unlike prior efforts that focus on propagation models using custom equipment [14,22,25,33], we experiment with commercial off-the-shelf 60GHz radios. We study key issues regarding the feasibility of 60GHz picocells, including range, sensitivity to motion and blockage, and interference footprint.…”

“…Our first contribution is to dispel common myths about 60GHz via extensive measurements and simulations, showing that the potential for 60GHz outdoor picocells can be realized without bending the laws of physics. Unlike prior efforts that focus on propagation models [22,14,25,33], we experiment with off-the-shelf 60GHz radios, and study key questions such as transmission range, robustness to blockage and user motion, and spatial reuse. We explore how these issues are affected by future hardware upgrades (especially in terms of increasing the number of antenna elements).…”

Mobile network traffic is set to explode in our near future, driven by the growth of bandwidth-hungry media applications. Current capacity solutions, including buying spectrum, WiFi offloading, and LTE picocells, are unlikely to supply the orders-of-magnitude bandwidth increase we need. In this paper, we explore a dramatically different alternative in the form of 60GHz mmwave picocells with highly directional links. While industry is investigating other mmwave bands (e.g. 28GHz to avoid oxygen absorption), we prefer the unlicensed 60GHz band with highly directional, short-range links (∼100m). 60GHz links truly reap the spatial reuse benefits of small cells while delivering high per-user data rates and leveraging efforts on indoor 60GHz PHY technology and standards. Using extensive measurements on off-the-shelf 60GHz radios and systemlevel simulations, we explore the feasibility of 60GHz picocells by characterizing range, attenuation due to reflections, sensitivity to movement and blockage, and interference in typical urban environments. Our results dispel some common myths, and show that there are no fundamental physical barriers to high-capacity 60GHz outdoor picocells. We conclude by identifying open challenges and associated research opportunities.

“…Devising a generic model of delay spread for varying types of antennas and environments is a difficult task at mm-waves because of its huge variation depending on the beamwidth and orientation of the Tx and Rx antennas. The seminal work [57] reports the delay spread up to 200 ns in an outdoor setting, while several papers report delay spreads lower than 20 ns in the best cases, even with NLOS outdoor scenarios, e.g., [26], [58]- [60]. A summary of delay spread values reported in major literatures with varying antenna configurations in indoor scenarios is available in [61].…”

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.

“…Fifth generation (5G) wireless communication systems that use mmWaves have been a research focus over the recent few years, and many research groups and industry entities have been conducting measurements and/or developing channel models at mmWave frequencies. For instance, outdoor propagation measurements and modeling at 60 GHz were carried out in various city streets [3], [4]; Aalto University performed outdoor channel measurements over 5 GHz of bandwidth from 81 GHz to 86 GHz in the E-band for point-to-point communications in a street canyon scenario in Helsinki, Finland [5]; 28 GHz channel propagation measurements and models have been conducted by Samsung and NYU WIRELESS for 5G mobile communications [2], [6], [7].…”

This paper presents millimeter-wave propagation measurements for urban micro-cellular and indoor office scenarios at 28 GHz and 73 GHz, and investigates the corresponding path loss using five types of path loss models, the singlefrequency floating-intercept (FI) model, single-frequency close-in (CI) free space reference distance model, multi-frequency alphabeta-gamma (ABG) model, multi-frequency CI model, and multifrequency CI model with a frequency-weighted path loss exponent (CIF), in both line-of-sight and non-line-of-sight environments. Results show that the CI and CIF models provide good estimation and exhibit stable behavior over frequencies and distances, with a solid physical basis and less computational complexity when compared with the FI and ABG models. Furthermore, path loss in outdoor scenarios shows little dependence on frequency beyond the first meter of free space propagation, whereas path loss tends to increase with frequency in addition to the increased free space path loss in indoor environments. Therefore, the CI model is suitable for outdoor environments over multiple frequencies, while the CIF model is more appropriate for indoor modeling. This work shows that both the CI and CIF models use fewer parameters and offer more convenient closed-form expressions suitable for analysis, without compromising model accuracy when compared to current 3GPP and WINNER path loss models.
