2.2 FCC Regulations
Note: Organizations and individuals should seek legal counsel before operating TTWS. The summary and interpretations of relevant FCC regulations are the opin- ions of the SSBT CoE and should not be taken as legal advice. They are provided here for informational and planning purposes only.
The FCC regulates interstate and international communications by radio, televi- sion, wire, satellite and cable.1 The FCC governs all devices that emit radio waves and regulates the frequencies and power levels on which the devices are allowed to operate. The FCC also distributes licenses for the use of frequency bands to individuals and to organizations, if required.2 TTWS fall under the categories of intentional radiators and radiolocators; some TTWS are also governed by UWB requirements. Key regulations from Title 47 of the Code of Federal Regulations (CFR) for TTWS include:
- [Parts 15, 90] Intentional radiators are required to have FCC certification.3 FCC-certified devices will have an FCC Identification (FCCID) number associ- ated with them and shall be labeled as such.4
- [Part 15] UWB TTWS Operation is limited to law enforcement, emergency rescue or firefighting organizations.
- UWB TTWS Operators (or the organization by which the operator is em- ployed by or volunteers for) must have a license in the Public Safety Radio Pool under Title 47 Code of Federal Regulations, Part 90.
