Question:   Are multiple transmitters addressed in the Commission's Part 15 Rules?

Answer:   There are no specific regulations that address the use of multiple Part 15 transmitters. In 1987-1989, the Commission revised its rules for unlicensed operation (GEN Docket No. 87-389). In the original Notice of Proposed Rule Making, the Commission proposed to prohibit the use of multiple transmitters to extend coverage area. However, the final Report and Order in this proceeding did not adopt that prohibition. In paragraph 137, the Commission stated that it concurred with the comments that multiple devices should be permitted provided, the individual transmitters comply with the rules and any emission resulting from the simultaneous operation of the individual, non-coordinated transmitters complies with the rules.
