TL;DR: The results show that linearly polarized (LP) directional antennas are more effective in combating multipath components than other types of antennas in OBS channels.

TL;DR: The results of multipath power delay profile measurements of 900-MHz mobile radio channels in Washington, DC, Greenbelt, MD, Oakland, CA, and San Francisco, California, are presented, revealing that at over 98% of the measured locations, RMS delay spreads are less than 12 mu s.

TL;DR: In this article, a computerized model provides a display of a physical environment in which a communications network is or will be installed, where the communication network is comprised of several components, each of which are selected by the design engineer and which are represented in the display.

TL;DR: In this paper, the authors summarized wireless communication research and activities above 100 GHz, overviews the results of previously published propagation measurements at D-band (110-170 GHz), provides the design of a 140 GHz wideband channel sounder system, and proposes indoor wideband propagation measurements and penetration measurements for common materials at 140 GHz which were not previously investigated.

TL;DR: The time cluster - spatial lobe (TCSL) modeling approach uses an alternative physically-based binning procedure and recreates 3GPP model parameters to generate channel impulse responses, as well as new parameters like the RMS lobe angular spreads useful in quantifying millimeter-wave directionality.
