ISART 2018 • Path Lost: Navigating propagation challenges for ultra-dense wireless systems
Synopsis of Panel and Workshop Topics

Tuesday Afternoon Panel—Mapping a Path Forward: Economics, Applications and Policy Implications

Ongoing research into propagation modeling supported by academic, industry, and federal spectrum research funds and industry-government collaborations have set the stage for marked improvements in modeling. A forward looking approach requires preliminary analyses of future rulemakings to determine use case scenarios and propagation morphologies and a research effort that leads—not lags—upcoming rulemakings. This session will explore policy implications of improved propagation modeling, discuss economic valuations of improved models, and explore means of coordinating research at the national level.

Moderator: Giulia McHenry, NTIA Chief Economist

Wednesday Morning Panel—Preparing the Road: Recent Advances in Modeling infrastructure

Vast improvements in terrain databases, computational power, and measurement data repositories have fostered a renaissance in propagation model development. Increased collaboration has led to improved measurement methods using narrowband and broadband channel sounders, more extensive measurement data sets, applications of common, high resolution terrain databases, precision geolocation, etc. However, more data does not necessarily mean better data or better results, thus the panel will also look at how to make sense of what tools are available and utilize what is available. The overall purpose of this panel is to promote a shared awareness of these new resources and their potential applications and value to different stakeholders.

Moderator: William ("Billy") Kozma, NTIA/ITS

Wednesday Afternoon Roadside Chat—Visions for the Future

Massive reductions in uncertainty and dramatic increases in modeling precision have transformational possibilities.  Our distinguished guests will share and debate their visions of what could lie beyond next-generation wireless if technology, policy, and economics can be aligned.

Moderator: Mark Gibson, CommScope

Wednesday Afternoon Panel—Driving Forward: Advances in Propagation Modeling

The availability of higher fidelity datasets and the desire for increased precision in modeling results has led to a re-visiting of how to handle modeling the radio environment. Features such as vegetation, building clutter, and 3D geometries had traditionally been either ignored by existing models or incorporated after-the-fact as a form of endpoint correction. This panel will look at ongoing research that strives to implicitly incorporate such features directly into the propagation model.

Moderator: Kevin Sowerby, University of Auckland 

Thursday Morning Panel—Tuning for Precision: Best Practices for Measurements and Models

Once models have been developed they need to be verified and validated. Verification is the process of establishing the truth, accuracy, or soundness  of something. Validation, on the other hand, demonstrates that a product or product component fulfills its intended use when placed in its intended environment. This panel will discuss techniques for accomplishing this and address typical timelines, roadblocks, risks, and challenges.

Moderator: Jacquelynne Houts, NASA Glenn

Thursday Afternoon Workshop—Benchmarking Measurements and Modeling

Highly accurate propagation measurements are key to both model development and model validation. This two-part workshop will focus on precision propagation measurements and best practices. In the first part, we will present a series of talks on precision propagation measurement systems, best practices for doing accurate propagation measurements, and ways to assess measurement uncertainty of ameasurement system. The second part of this session will consist of live demos with actual propagation measurement systems. We will demonstrate best measurement practices with these systems and what is needed to get the best out of a propagation measurement system. In addition we will highlight problems that can occur if best practices are not followed..

Hosts: Chriss Hammerschmidt, Robert Johnk, and Mark McFarland, NTIA/ITS; Jeanne Quimby, NIST/CTL
