FCC Improves Spectrum Utilization Thru Use of Part 15

This paper reviews the history of Part 15 which was originally adopted in 1938 and revised in the period 1949-1957. It then shows how in three specific cases the Commission increased the efficiency of use of the spectrum by adopting its Part 15 regulations to permit the operation of RF operated garage door openers, FM wireless microphones, and auditory training systems. Finally, the paper discusses the certification program for devices operating under Part 15.
