Testing for FCC standards

Meet FCC requirements for wireless products

Ensuring compliance with Federal Communications Commission (FCC) regulations is essential for any electronic or wireless product entering the U.S. market. FCC compliance testing verifies that devices emitting radio frequency energy – such as smartphones, laptops, routers, wearables and IoT devices – meet strict requirements for electromagnetic compatibility (EMC), radio frequency emissions and RF exposure (SAR or power density).

Testing must be conducted at FCC-accredited laboratories. Passing the compliance tests leads to an FCC ID, which is necessary for legal marketing and sales within the U.S. The testing process references CFR Title 47 (CFR47), relevant KDB (Knowledge Database) guidance and ANSI C63 standards, ensuring standardized and reproducible methods across product types.

Early pre-compliance testing during product development helps identify potential failures before final submission, reducing costly redesigns and retesting later in the process.

Master your FCC compliance testing challenges

FCC requirements change as wireless technologies evolve. Manufacturers face several recurring challenges in meeting these standards:

  • Keeping up with changing regulations: Revisions must be actively monitored and incorporated into design and verification workflows.
  • Increased wireless complexity: Modern devices integrate multiple wireless technologies that operate across various frequency bands.
  • EMC and emissions testing: Compliance with radiated and conducted emissions limits per CISPR and ANSI C63 standards is a fundamental but challenging part of FCC approval.
  • RF exposure and SAR compliance: Wireless devices must comply with human exposure limits for specific absorption rate (SAR) or power density (PD).

High-performance solutions for FCC compliance testing

Our test systems delivers end-to-end coverage for FCC testing – from EMC and RF exposure validation to DFS and 6 GHz compliance:

Case studies with our FCC compliance testing solutions

Case study 1: Dynamic frequency selection (DFS) in the 5 GHz band

DFS ensures that Wi-Fi devices can share spectrum with radar systems. The FCC’s KDB 905462 defines strict waveform and detection requirements.

Challenges:

  • Generating and synchronizing radar waveforms with high accuracy
  • Ensuring repeatable detection probability results across test cycles

Solution:

The R&S®TS8997 test system delivers high-fidelity waveform generation, wide dynamic range and full automation – simplifying the complex DFS testing workflow.

Case study 2: 6 GHz band device testing (KDB 987594)

The opening of the 6 GHz band (5.925-7.125 GHz) for unlicensed use has enabled Wi-Fi 6E and Wi-Fi 7 technologies. Compliance testing under KDB 987594 requires validation across multiple device classes (LPI, SP, VLP) and coordination with AFC systems for standard-power devices.

Challenge:

Limited flexibility when testing client devices requiring standard-power AP operation under AFC control.

Solution:

Custom test configurations and application notes support complete and efficient testing for all 6 GHz device categories.
