We describe extensions to the Network Simulator version 3 (ns-3) New Radio (NR) sidelink simulator for higher-fidelity packet error models based on an extensive simulation campaign using the National Institute of Standards and Technology (NIST) Fifth

Rydberg atom reception of a handheld UHF frequency-modulated two-way radio

February 10, 2026
Author(s)
Noah Schlossberger, Tate McDonald, Nikunjkumar Prajapati, Christopher Holloway
Rydberg atoms, due to their large polarizabilities and strong transition dipole moments, have been utilized as sensitive electric field sensors. While their ability to detect modulated signals has been previously demonstrated, these studies have largely

Two-Tier Vector-Network-Analyzer Calibrations for Uncertainties in Laboratory-Based Over-the-Air and Channel Measurements

October 23, 2025
Author(s)
Paritosh Manurkar, Sudantha Perera, Catherine Remley, Dylan Williams, Mohamed Hany, Joshua Kast, Robert Horansky
We present a straightforward and systematic approach for identifying the dominant uncertainties related to vector network analyzer measurements of chambers utilized for free-field test of wireless devices. We assess the uncertainty related to long cable

System-Level Calibration of a Millimeter-Wave Vector Signal Analyzer with Uncertainties

August 15, 2025
Author(s)
Joshua Kast, Paritosh Manurkar, Catherine Remley, Dylan Williams, Robert Horansky
We describe the system-level calibration of a vector signal analyzer operating in the 28 GHz frequency band, including the determination of uncertainties in the magnitude and phase of measurements of a traceably characterized calibration waveform. We then
