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

Hale, Mohit S. Mujumdar, Nada T. Golmie
National Metrology Institutes (NMIs) around the world are charged with supporting industry through improved measurement science and by providing a traceability path to fundamental physical standards. Mobile wireless communications have become a ubiquitous

Quasi-deterministic Model for Doppler Spread in Millimeter-wave Commmunication Systems

May 18, 2017
Author(s)
Jian Wang, Camillo Gentile, Peter B. Papazian, Jae-Kark Choi, Jelena Senic
The most salient feature differentiating millimeter-wave communication systems from their predecessors will be the steerable pencilbeam antennas at the transceivers. As opposed to conventional widebeam antennas, only a few multipath components will be

Pathloss Models for Indoor Hotspot Deployment at 83.5 GHz

December 3, 2016
Author(s)
Camillo Gentile, Jelena Senic, Peter B. Papazian, Jae-Kark Choi, Kate Remley
Conventional pathloss models are based on the received power from an omnidirectional antenna. Millimeter-wave receivers, conversely, will feature highly directional antennas that can be steered towards the angle with maximum power, exploiting their high

Peer-to-Peer Urban Channel Characteristics for Two Public-Safety Frequency Bands

October 1, 2015
Author(s)
Catherine A. Remley, David W. Matolak, Camillo A. Gentile, Christopher L. Holloway, Qiong Wu, Qian Zhang
We report on ground-based wireless channel characteristics for an urban environment in two public safety bands. Results are based upon measurements taken in Denver in June 2009. The public safety bands we investigated are the 700 MHz and 4.9 GHz bands

Calibration of Millimeter-wave Channel Sounders for Super-resolution Multipath Component Extraction

April 9, 2015
Author(s)
Peter B. Papazian, Jae-Kark Choi, Jelena Senic, Peter J. Jeavons, Camillo Gentile, Nada T. Golmie, Roy Sun, David R. Novotny, Kate Remley
Millimeter-wave communication systems will rely on highly directional antennas to compensate for the greater pathloss expected in their frequency bands of operation. Electronic beamforming, hence, will form a cornerstone for the technology. For the

Nationwide Public Safety Broadband Network Deployment: Network Parameter Sensitivity Analysis

March 15, 2015
Author(s)
Richard A. Rouil, Antonio Izquierdo Manzanares, Camillo A. Gentile, David W. Griffith, Nada T. Golmie
The legislation included in the middle class tax relief and job creation act of 2012 established the First Responder Network Authority (FirstNet) for the purpose of deploying and running a nationwide Long Term Evolution (LTE) network for Public Safety

Modeling a Nationwide Public Safety Broadband Network

June 1, 2013
Author(s)
Richard A. Rouil, Antonio Izquierdo Manzanares, Michael R. Souryal, Camillo Gentile, David W. Griffith, Nada T. Golmie
As governments plan nationwide, interoperable broadband networks for their public safety services, the challenge arises of determining how and where to invest limited resources to meet demanding requirements. The United States is at the early stages of

Wireless Network Deployment in the Smart Grid: Design and Evaluation Issues

November 30, 2012
Author(s)
Camillo A. Gentile, David W. Griffith, Michael R. Souryal
The projected use of the power grid for “smart” applications such as advanced metering and distributed automation will require highly reliable, secure, well-designed and managed communication networks. While many of the benefits of wireless communications

Throughput and Delay Analysis of Half-Duplex IEEE 802.11 Mesh Networks

June 6, 2011
Author(s)
Camillo A. Gentile
Emerging technologies for mesh networks can provide users with last-mile service to an access point by forwarding data through wireless relays instead of through expensive wireline infrastructure. While an extensive amount of literature on mesh networks
