Radio Frequency (RF) Engineering Expert Witness
Radio frequency disputes are technical enough that attorneys may not have a clear idea of what happened: equipment malfunction, spectrum interference, signal loss, improper maintenance, or a system that was improperly designed or tested. I bring published, peer-reviewed research experience in RF measurement and propagation to these cases.
I spent years researching and developing RF propagation and interference measurement techniques, RF propagation models, and system performance at our nation’s spectrum and communications lab, the Institute for Telecommunication Sciences. I presented my work at international technical symposiums, including the International Union of Radio Science and the IEEE Antenna Measurement Techniques Association, and published in the IEEE. This is a different tier of technical grounding than most RF-adjacent experts can bring to a case.
What I Investigate
RF Equipment Malfunction
Cases involving public safety and emergency communications systems, where a link in the signal chain may have malfunctioned and important messages don’t get through.
Industrial Communications Systems
Factories, mines, warehouses, and other harsh environments, where specialized communications systems are used to protect workers, property, product, and the environment.
Interference and Receiver Performance
Whether a receiver’s performance was degraded by an outside signal source, and whether that interference was foreseeable given the systems operating nearby.
RF Mitigation
Reviewed RF mitigation plans for rooftop cellular base station installations and provided opinion on the validity of the RF emission predictions.
A Research Background Courts Can Rely On
I implemented rigorous research methods and techniques while at the government in support of the government’s management of the radio spectrum. My research involved public safety communication systems and RF research commissioned by the US Department of Defense (DoD), the National Telecommunications and Information Administration (NTIA), and other federal agencies. I validated RF propagation models using quality sciences (Six Sigma) techniques, classified RF propagations environments using statistical learning methods.
Discuss Your Case
Fifteen minutes covers the engineering question, any conflicts, and whether my background fits. No charge, no obligation.
My Process
- Initial call. You describe the RF or interference question, and I tell you directly whether it’s a fit.
- Technical review. I review the relevant system specifications, measurement data, or interference reports. I perform my own measurements if necessary.
- Analysis or modeling. I apply the same rigor I did as a researcher to the specific facts of the case.
- Ongoing communication. I share findings as the analysis develops.
- Report and testimony. A written opinion, and testimony where the case requires, explained in terms a judge or jury can genuinely follow.
Why Attorneys Choose Me for RF Cases
- Published, peer-reviewed research, not just field consulting experience picked up informally over a career.
- International conference presentations on RF measurement and propagation topics, including sessions where I served as session co-chair.
- I’ve never had an opinion limited or excluded. No Daubert challenge has ever succeeded against me — my RF methodology, like my other engineering work, has held up under scrutiny.
- Works alongside my telecommunications and cellular practice areas, so RF disputes that overlap with broader wireless or network questions don’t require bringing in a second expert for the adjacent issue.
- Statistical rigor built in. My education in the quality sciences means RF findings aren’t just measured, they’re validated against the kind of scrutiny that holds up.
- Multi-disciplinary Capabilities. My strong background in RF, wireless, electrical, and electronic phenomena supports complicated cases that span several fields of expertise.
FAQs
Whether a radio frequency system caused or suffered interference, whether signal coverage matched what was represented, and whether a system was designed and installed appropriately for its physical environment.
RF engineering focuses specifically on how radio signals propagate, interfere, and perform in physical environments. My research background is specifically in measuring and modeling that behavior at a national research level, not just describing systems at a higher, more general level the way a broader telecommunications review might.
Yes. My work spans spectrum interference questions at the systems level and the performance of the specific equipment operating within that spectrum.
That’s the point of translating research-level work into plain language. I’ve spent my career presenting highly technical RF findings to technical peers at conferences, and I apply that same discipline, simplify without distorting, when I’m in front of a judge or jury.
