Abstract: This report includes NTIA measurements of characteristics of nonlicensed devices. These devices are authorized under the FCC Rules in CFR 47, Part 15. The measured values are intended for use by the Government in analysis of potential interference between nonlicensed devices and Government telecommunication systems. Facilities, equipment, and procedures to measure the characteristics of nonlicensed devices are described. Measurements include field intensities, harmonic levels, radiation patterns, emission spectra, receiver thresholds, and saturation levels of nonlicensed devices.

Keywords: emission spectra; Nonlicensed Devices; Part 15 Devices; Radiation Pattern; Receiver Saturation Bandwidth; Receiver Saturation Level; Receiver Threshold; Transmitted Field Intensity; Transmitter Harmonic Level
