{"data":{"id":"us/47-cfr-95.2569","jurisdiction":"us","citation":"47 CFR 95.2569","heading":"MedRadio field strength measurements.","body":"Compliance with MedRadio equivalent isotropic radiated power (M-EIRP) limits can be determined by measuring the radiated field strength from the transmitter type, in accordance with the rules in this section.\n(a) Radiated field strength values corresponding to the M-EIRP limits in § 95.2567 are given in the table in this paragraph, for an open area test site, and for a test site equivalent to free space, such as a fully anechoic test chamber. Field strength is measured at a distance of 3 meters from the equipment under test.\nM-EIRP limit Open area (mV/m) Free space (mV/m)\n1 mW 115.1 57.55\n25 μW 18.2 9.1\n250 nW 1.8 0.9\n100 nW 1.2 0.6\n(b) Compliance with the maximum transmitter power requirements in § 95.2567 is based on measurements using a peak detector function and measured over an interval of time when transmission is continuous and at its maximum power level. In lieu of using a peak detector function, measurement procedures that have been found to be acceptable to the FCC in accordance with § 2.947 of this chapter may be used to demonstrate compliance.\n(c) For a MedRadio transmitter intended to be implanted in a human body, radiated emissions and M-EIRP measurements for transmissions by stations authorized under this section may be made in accordance with an FCC-approved human body simulator and test technique. Guidance regarding dielectric parameters for the tissue-equivalent material can be found in the Office of Engineering and Technology (OET) Laboratory Division Knowledge Database (KDB).","path":["Title 47—Telecommunication","CHAPTER I—FEDERAL COMMUNICATIONS COMMISSION","SUBCHAPTER D—SAFETY AND SPECIAL RADIO SERVICES","PART 95—PERSONAL RADIO SERVICES","Subpart I—Medical Device Radio Communications Service"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-47.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:26:28Z","sha256":"0e524629bc09df3749473de11cee69bf1c502af0e4531b3a7181b994c9a4ffe5","source_id":"us-cfr","stale":true,"prev":"us/47-cfr-95.2567","next":"us/47-cfr-95.2571"},"notice":"GroundRules: Original legal text.
