Communications Technology Laboratory /Spectrum Technology and Research Division

Applied Systems Metrology Group

Applied Systems Metrology Group

Develops measurement techniques to characterize and evaluate commercial off-the-shelf (COTS) and closed-box communication systems operating in congested and dynamic radio frequency (RF) spectrum environments.  Identifies future spectrum issues and lays foundations for spectrum measurements and device testing. 

Major Activities:

  • Technical support for NASCTN projects
  • Testbed automation and sensor development 
  • Methodologies for communication systems testing and spectrum monitoring

Projects

CBRS Sharing Ecosystem Assessment

Ongoing
Background: In 2020, FCC auction 105 auctioned licenses in the Citizens Broadband Radio Service (CBRS). CBRS (3.55 GHz to 3.7 GHz) has a three-tiered framework to accommodate shared federal and non-federal use of the band. The DoD 3.5 GHz Transition Plans focus on ecosystem validations

Adaptive Closed-Box Interference Susceptibility Testing

Ongoing
The primary project objective is to develop new methods for experimental characterization of dynamic interference impacts on adaptive, closed-box COTS communication links. Specific goals include: Dissemination of low-cost, general-purpose testbed designs for interference testing. Methods to assess
Spectrum

In-Situ RF Emissions Metrology

Ongoing
Objectives The In-Situ RF Emissions Metrology Project blends expertise in traditional spectrum monitoring, digital signal processing and statistics with applied, situationally relevant, measurement methods, modeling, and simulation techniques to build towards assessments of: The time, frequency
