NSF NRAO Hosts SpectrumX Field Experiment at the Very Large Array

The U. S. National Science Foundation's National Radio Astronomy Observatory (NSF NRAO) recently collaborated with NSF SpectrumX, the Spectrum Innovation Center, to host a large-scale spectrum research experiment at the U.S. National Science Foundation Very Large Array (NSF VLA) in New Mexico.

This week-long effort, conducted in July 2025, brought together researchers, students, and experts from across academia, government, and industry to study spectrum usage in the 7.125 to 7.4 GHz band-frequencies of increasing importance to both science and emerging sixth-generation (6G) communications. Because of the unique sensitivity of the NSF VLA, the experiment provided a vital opportunity to explore how future spectrum allocations may affect radio astronomy and other passive scientific applications.
