What this outcome means
The FAA studied the proposal and concluded it would not be a hazard to air navigation. A no-hazard determination is not permanent — it carries an expiration date, and if the structure is not built by then the case has to be re-filed.
The proposal, in the filer's words
"Adding frequencies only. This site will comply with the operational parameters agreed to in collaboration with the FAA as part of its 5G C-band compatibility evaluation process as they may evolve over time."
