TL;DR: In this paper, the authors provide an overview of the features of 5G wireless communication systems for use in the mmWave frequency bands, and the channel modeling efforts of many international groups for both licensed and unlicensed applications are described.

TL;DR: The current state of research in on-chip integrated antennas is presented, several pitfalls and challenges for on- chip design, modeling, and measurement are highlighted, and several antenna structures that derive from the microwave microstrip and amateur radio art are proposed.

TL;DR: A channel sounder that operates at 38 and 60 GHz with a passband bandwidth of 1.9 GHz is presented and provides sub-ns RMS delay spread measurement resolution and angle-of-arrival (AOA) capabilities.

TL;DR: Small-scale fading measurements for 28 GHz outdoor millimeter-wave ultrawideband channels using directional horn antennas at the transmitter and receiver are presented and signal amplitudes reach a correlation of 0 after 2 and 5 wavelengths in LOS and NLOS co-polarized V-V antenna scenarios.

TL;DR: In this article, a system and method for providing security to a wireless communication system having wireless communication components positioned at different locations within a physical environment are provided, including an access point and a network device, where an indicator is presented in the site-specific representation on the display when an erroneous authentication request or other undesired transmission is received by the network device or the access point.
