62.5-GHz Phased-Array Channel Sounder for Double-Directional Angle Estimation

July 1, 2019
Author(s)
Peter B. Papazian, Derek Caudill, Camillo Gentile, Jack Chuang, Nada T. Golmie
The paper describes implementation of phased array antennas for use in a wideband channel sounding system. The antennas are 62.5 GHz prototypes, utilizing SiGe chips on a printed circuit-board. Each board consists of two 16-element series-fed patch array

Omnidirectional Channel Sounder with Phased-Array Antennas for 5G Mobile Communications

June 30, 2019
Author(s)
Derek Caudill, Peter B. Papazian, Camillo Gentile, Jack Chuang, Nada T. Golmie
We describe a 60-GHz channel sounder with phased-array antennas and 1-GHz bandwidth. It estimates the angle of departure (AoD)/angle of arrival (AoA) of channel multipath components (MPCs) by sweeping the antenna space of the transmitter/receiver through 5

System Distortion Model for the Cross-Validation of Millimeter-Wave Channel Sounders

Camillo Gentile, Andreas Molisch, Jack Chuang, Anuraag Bodi, Anmol Bhardwaj, Ozgur Ozdemir, Ismail Guvenc, Zihang Cheng, Thomas Choi, Robert Mueller
Because millimeter-wave directional channel measurements are time-consuming and expensive to collect, there is considerable interest in combining measurement data obtained with different channel sounders in order to yield more comprehensive datasets. The

Methodology for Multipath-Component Tracking in Millimeter-Wave Channel Modeling

March 1, 2019
Author(s)
Chiehping Lai, Roy Sun, Camillo Gentile, Peter B. Papazian, Jian Wang, Jelena Senic
In this paper, we describe an extensive channel-measurement campaign - including 325 unique transmitter-receiver configurations - conducted in a lecture room with our 3D double- directional 60-GHz channel sounder. The receiver was mounted on a mobile robot

EMC and Metrology Challenges for 5G and Beyond

December 7, 2018
Author(s)
Perry F. Wilson, Catherine A. Remley, William F. Young, Camillo A. Gentile, John M. Ladbury, Dylan F. Williams
The potential to connect people and devices anywhere and anytime is driving the development and deployment of a multitude of wireless systems. Wireless connectivity is central to advanced communication technologies, the internet of things (IoT), the smart

Millimeter-Wave Channel Measurement and Modeling: A NIST Perspective

December 7, 2018
Author(s)
Camillo A. Gentile, Peter B. Papazian, Nada T. Golmie, Catherine A. Remley, Peter G. Vouras, Jelena Senic, Jian Wang, Jack Chuang, Ruoyu Sun
The exponential increase in wireless data transmission from smartphones has led to the saturation of the sub-6-GHz bands, forcing cellular providers to migrate to the millimeter-wave (mmWave) regime for 5G. Although available channel bandwidths will grow

Millimeter-Wave Propagation Channels vs. Synthetic Beamwidth

December 7, 2018
Author(s)
Roy Sun, Camillo A. Gentile, Jelena Senic, Peter G. Vouras, Peter B. Papazian, Nada T. Golmie, Catherine A. Remley
High-gain narrow-beam antennas or beamformed antenna arrays will likely be used in millimeter- wave (mmWave) bands and 5G to mitigate the high path loss. Since many multipath components may be excluded by the narrow beam, the mmWave propagation channels

Quasi-Deterministic-Channel-Propagation Model for a Data Center at 60 GHz

April 30, 2018
Author(s)
Camillo Gentile, Peter B. Papazian, Roy Sun, Jelena Senic, Jian Wang
We describe a measurement campaign conducted in a data center, a unique environment in which transceivers are positioned above the server racks. A total of 80 channel acquisitions, including small-scale measurements, were recorded using our 3D double

Angle- and Delay-Dispersion Characteristics in a Hallway and Lobby at 60 GHz

April 9, 2018
Author(s)
Roy Sun, Peter B. Papazian, Jelena Senic, Camillo A. Gentile, Catherine A. Remley
In this paper, we present results from measurement data collected in a hallway and lobby up to 33 meters in line-of-sight and non-line-of-sight conditions. The data was collected using a custom double-directional 60 GHz channel sounder. By tracking the

Unsupervised Clustering for Millimeter-Wave Channel Propagation Modeling

February 11, 2018
Author(s)
Jian Wang, Camillo Gentile, Jelena Senic, Roy Sun, Peter B. Papazian
We have designed and assembled millimeter-wave channel sounders at 28, 60, and 83 GHz. They can measure the three-dimensional (azimuth and elevation) double-directional angle (angle-of- departure and angle-of-arrival) of channel multipath components as

Increasing Public Safety Broadband Network Resiliency Through Traffic Control

February 1, 2018
Author(s)
Richard A. Rouil, Wesley D. Garey, Camillo A. Gentile, Nada T. Golmie
Long Term Evolution (LTE)-based cellular networks are being deployed around the world to provide public safety with enhanced capabilities and access to broadband technology. In the United States, the First Responder Network Authority (FirstNet) is on the

Methods for Channel Sounder Measurement Verification

September 23, 2017
Author(s)
Kate Remley, Camillo Gentile, Alenka Zajic, Jeanne Quimby
We describe an activity of the 5G mmWave Channel Sounder Alliance to verify the hardware performance of channel sounders operating at mmWave frequencies. Such verification procedures are critical when attempting to compare data from sounders having
