... The wireless coexistence work is linked to the group's work on wireless signal characterization, as coexistence depends on the nature and strength of the interfering signals. The Spectrum Technology and Research Division cited several examples of past or current work in this domain, including the following: ● Wi-Fi and Bluetooth coexistence as a testbed for general coexistence studies; ● Characterization of user terminal emissions for predicting coexistence between Advanced Wireless Services (AWS)

... Spectrum Sensing The Spectrum Technology and Research Division made a pivot of resources to address the COVID19 pandemic. The group used machine learning to infer a person's breathing from variations of the Wi-Fi received signal (the physical movement of respiration caused measurable changes in signal)

... Key Recommendation 10: CTL should engage actively with industry, including wireless standards groups, to remain aware of upcoming and pressing spectrum coexistence issues. The Spectrum Technology and Research Division should develop a framework that allows fast pivoting of resources (and techniques)

... Key Recommendation 11: The Spectrum Sharing and Sensing team should collaborate closely with the Rydberg Atom-based Radio Frequency Field Probe team to examine the probe's potential application to spectrum sensing and metrology and identify key technology opportunities in the space of spectrum metrology. PORTFOLIO OF SCIENTIFIC EXPERTISE Personnel Expertise The Spectrum Technology and Research Division is well staffed with many of its team members recognized as experts in their field.

... For example, NIST helped guide the standards for CBRS within the Wireless Innovation Forum. Since the adoption of CBRS rules by FCC in 2015, NIST representatives participated in Wireless Innovation Forum standards meetings and made important contributions to a wide range of standards items, including propagation models, interference statistics, protocols, and certification test codes.
