NOM-208-SCFI-2016 is an Official Mexican Standard titled “Products. Radiocommunication systems that employ the dispersed spectrum technique (Radiocommunication equipment) Frequency hopping radiocommunication and digital modulation equipment to operate in the 902 MHz-928 MHz, 2400 MHz-2483.5 MHz, and 5725 MHz-5850 MHz bands, Specifications and test methods.” The standard aims to ensure the safety, reliability, and efficient spectrum use of short-range radiocommunication devices, protecting consumers and preventing interference with other communication systems.

NOM-208-SCFI-2016: Scope and Applicability
The standard applies to radiocommunication equipment using spread spectrum techniques—specifically frequency hopping and digital modulation—operating in the following unlicensed frequency bands:
- 902 MHz–928 MHz (often used for industrial, scientific, and medical devices).
- 2400 MHz–2483.5 MHz (common for Wi-Fi, Bluetooth, and Zigbee).
- 5725 MHz–5850 MHz (used for higher-bandwidth short-range applications).
Covered products include
- Wireless devices like Wi-Fi routers, Bluetooth headsets, cordless phones, and IoT sensors.
- Short-range devices (SRDs) marketed, imported, or distributed in Mexico.
Exclusions
- RFID devices in the 900 MHz range subject to separate testing processes.
- Equipment not operating in the specified bands or using different modulation techniques.
NOM-208-SCFI-2016 It applies to new products entering the Mexican market, replacing NOM-121-SCT1-2009 and NOM-EM-016-SCFI-2015.
Key Requirements
1. Technical Specifications
- Frequency Adherence: Devices must operate strictly within their assigned bands to avoid interference.
- Output Power: Must comply with maximum permissible power levels (e.g., ≤1 W for most SRDs) to limit signal range and interference.
- Frequency Stability: Must maintain stable frequencies to prevent drift into unauthorized bands.
- Bandwidth and Channel Spacing: Must adhere to specified limits for efficient spectrum use.
- Aligns with Technical Provision IFT-008-2015 (or its latest update) for detailed parameters.
2. Performance Requirements
- Ensures reliable operation without causing harmful interference to other radio systems.
- Devices must meet minimum performance criteria for signal integrity and modulation accuracy.
3. Test Methods
- Based on IFT-008-2015, incorporating Mexican standards (e.g., NMX series) and international norms (e.g., FCC Part 15 equivalents).
Tests include
- Evaluation is based on IFT-008-2015, utilizing methodologies derived from Mexican standards (NMX) and international benchmarks (such as FCC Part 15).
4. Labeling
- Products must be clearly marked with their IFT ID (provided upon successful homologation). This label serves as the consumer’s and the authority’s guarantee that the device is legal for use in Mexico.
5. Compliance and NOM-208-SCFI-2016 Certification
- Requires a Certificate of Conformity from accredited certification bodies and IFT homologation.
- Testing must be conducted by accredited labs under EMA (Entidad Mexicana de Acreditación) guidelines.
- Certificates from prior standards (NOM-121, NOM-EM-016) remain valid until expiration but cannot be extended to new models.
- Frequency stability under temperature and voltage variations.
- Output power measurement.
- Bandwidth occupancy and hopping sequence verification.
Purpose and Enforcement
NOM-208-SCFI-2016 ensures short-range devices like Wi-Fi and Bluetooth equipment operate safely and efficiently, protecting consumer health, safety, and telecommunications infrastructure. It aligns with Mexico’s spectrum management goals under the Ley Federal de Telecomunicaciones y Radiodifusión. Enforcement is managed by:
- Secretaría de Economía: Oversees NOM compliance and certification.
- IFT: Regulates spectrum use and conducts market surveillance.
- PROFECO: Monitors consumer products.
- Customs authorities: Verify certificates at import.
