FAQs – Regulatory Prerequisites
This section answers some common questions on regulatory requirements for FCC as a prerequisite for PTCRB in the US and RED as a prerequisite for GCF in the EU and many global markets, with a specific focus on IoT devices using integrated (pre-certified) cellular modules.
FCC Certification
Yes. FCC authorization is a prerequisite for PTCRB certification. A device must hold valid FCC approval before it can be submitted for PTCRB review.
Yes. Even when using an FCC-certified cellular module, the end device still requires FCC authorization unless it strictly meets modular integration conditions. Most IoT products require either:
- FCC Supplier’s Declaration of Conformity (SDoC), or
- A new FCC ID for the end product
depending on the integration and radio configuration.
The FCC path depends on:
- Whether the module is single-modular or limited modular approved
- Antenna type and gain
- Co-located radios (Wi-Fi, BLE, GNSS, etc.)
Improper assumptions about “module reuse” are a common cause of PTCRB delays.
Yes. Antenna changes almost always trigger FCC evaluation, as RF exposure, output power, and emissions can change at the end-device level.
Planning can be done in parallel, but FCC approval must be completed first before PTCRB certification can proceed to final approval.
CE/RED Compliance
The Radio Equipment Directive (RED) is a mandatory EU regulatory requirement. RED compliance is a prerequisite for GCF certification, as GCF assumes the device meets regional regulatory requirements.
Yes. RED compliance applies to the complete end product, not just the module. Integration, antennas, power levels, and additional radios must be assessed at the device level.
RED assessment commonly includes:
- Article 3.1(a): Health & safety
- Article 3.1(b): EMC
- Article 3.2: Efficient use of radio spectrum
The applicable scope depends on device configuration and supported technologies.
Not always. Many IoT devices can follow self-declaration if harmonized standards are fully met. However, Notified Body review may be required if:
- Harmonized standards are not fully applied
- New or non-standard radio technologies are used
Yes. As with FCC, antenna design and placement directly affect RED compliance, even when using a pre-approved module.
No. While a GCF-certified module reduces risk, the end device still requires GCF evaluation, especially for RF performance and integration-related impacts.
Some test reports and technical documentation can be leveraged, but GCF has its own declaration process and acceptance criteria. Proper planning helps minimize duplicate testing.
Assuming “module certified” means “device certified.”
Regulatory (FCC/RED) and industry (PTCRB/GCF) approvals apply to the final integrated product, not just the radio module.
Prowess IoT ensures:
- Correct regulatory path selection (FCC & RED)
- Alignment of regulatory approvals with PTCRB and GCF
- Early identification of integration risks
- Reduced re-testing, delays, and certification cost
