The Instituto Federal de Telecomunicaciones (IFETEL) released Disposición Técnica IFT-016-2024 on February 7, 2025. This document defines specifications, limits, and testing methods for low-power radiocommunications devices (LPDs) operating in frequency ranges from 30 MHz to 3 GHz.
IFT-016-2024 applies to devices within the following bands: 30-40.02, 40.02-40.98, 40.98-50, 54-72, 72-73, 76-88, 74.6-74.8, 75.2-75.4, 74-76, 88-108, 143.6-144, 144-148, 148-149.9, 149.9-150.05, 156.7625-156.7875, 156.8125-156.8375, 161.9375-161.9625, 161.9875-162.0125, 174-216, 216-220, 220-225, 312-322, 399.9-400.15, 406.1-430, 430-440, 470-608, 614-698, 698-806, 806-902, 902-928, 928-960, 1427-1518, 1710-1780, 1780-1850, 1850-1920, 1880-1900, 1920-1930, 1930-2000, 2000-2025, 2110-2200, 2290-2300, 2300-2400, 2400-2483.5, 2483.5-2500, and 2500-2690 MHz.
Exceptions include frequency bands designated for emergency, safety, search, or rescue communications; spectrum protected in the National Frequency Allocation Table (NFAT); and applications inconsistent with NFAT band usage. The scope excludes frequency-hopping and digital modulation devices regulated under IFT-008 (NOM-208) in the 902-928 MHz, 2400-2483.5 MHz, and 5725-5850 MHz bands.
The regulation will take effect 270 days after publication, on November 4, 2025. Certification Bodies (CBs) and Testing Labs may begin conformity assessments from that date, provided they hold accreditation from IFT or an authorized Accreditation Body. Accreditation and authorization processes may start on February 8, 2025.
Certificates of Homologation (CoHs) issued under the Guidelines for secondary use of frequency bands will remain valid until expiration and will not require certification compliance monitoring. Devices with CoHs under the new regulation must meet the parameters in IFT-016-2024. LPDs outside the 30 MHz–3 GHz range that receive a Type B CoH must also comply with the technical and operational requirements in IFT-016-2024, except for cases involving protected spectrum for emergency, safety, search, or rescue communications, where NFAT conditions prevail.
