FCC Adds OTA Efficiency Threshold to RF Module Approval

On June 28, 2026, the U.S. Federal Communications Commission (FCC) updated the certification path for integrated RF Modules through KDB 996369 D07v07, adding a mandatory OTA radiation efficiency test and a minimum 45% requirement for the 2.4 GHz band. Because the rule takes effect on October 1, 2026 and applies to RF Modules exported to the United States, the change is directly relevant to Chinese OEM and ODM suppliers, certification planning, technical documentation, and delivery schedules tied to the U.S. market.

What the FCC update confirms

The confirmed change is limited but operationally significant. According to the provided event information, the FCC released KDB 996369 D07v07 on June 28, 2026. The update applies to integrated RF Modules, including Wi-Fi 6E/7 modules and Sub-GHz IoT modules. It introduces mandatory OTA radiation efficiency testing, sets a minimum threshold of 45% for the 2.4 GHz band, and requires that the result be explicitly stated in the certification report.

The effective date provided is October 1, 2026. The event summary also states that the rule affects all Chinese OEM and ODM manufacturers exporting RF Modules to the U.S. market.

Where the pressure is likely to appear first

Certification workflows will become more document-sensitive

From an industry perspective, certification-related businesses are among the first to feel the change because the requirement is no longer limited to internal technical evaluation; it must also appear in the formal report. That means test completion and report wording both become relevant checkpoints. For companies preparing U.S.-bound module approvals, attention will need to shift toward whether OTA efficiency data is available, whether the 2.4 GHz result meets the threshold, and whether the certification package reflects the new reporting requirement.

OEM and ODM export programs may face earlier design review pressure

Chinese OEM and ODM suppliers serving the U.S. market may be affected at the product planning and export preparation stages. Analysis shows the new threshold can influence which module designs remain suitable for ongoing U.S. programs, especially where approval timing and customer delivery commitments are tight. The practical issue is not only passing a test, but also avoiding late-stage certification surprises that could interfere with shipment readiness or customer acceptance documentation.

Procurement and supply chain decisions may require additional screening

Buyers, sourcing teams, and supply chain service providers may need to treat OTA efficiency evidence as part of supplier qualification for U.S.-facing projects. Observably, once a threshold must be declared in certification materials, purchasing decisions may become more dependent on whether a module supplier can provide compliant reports within the required timeline. This can affect model selection, supplier comparison, replacement planning, and the timing of procurement commitments linked to export delivery.

Testing and compliance support functions may need closer coordination

Testing service providers and compliance teams may also see changes in workload and review focus. What deserves closer attention is the coordination between technical testing, report issuance, and customer-facing compliance files. Even where the rule itself is clear at a high level, companies involved in test execution or submission support will likely need to watch how the requirement is interpreted in actual certification preparation and customer document requests.

What companies should watch before the rule takes effect

Review whether current U.S.-bound modules have a gap against the new threshold

Companies with integrated RF Modules intended for the U.S. market should first identify which active or planned products fall within the affected scope. Analysis shows that modules already positioned for U.S. export may require a focused check on whether OTA radiation efficiency data for the 2.4 GHz band is available and whether it can be presented in the required certification format.

Check reporting language and technical file readiness

Because the event summary states that the efficiency result must be explicitly shown in the certification report, technical file management becomes a practical issue. Companies should pay attention to whether reports, supporting test documents, product files, and customer compliance packages are aligned with the new requirement. At this stage, it is more appropriate to treat documentation readiness as a compliance issue, not just an administrative detail.

Revisit delivery timing for projects crossing the October 1, 2026 date

For export orders, model transitions, or customer programs that overlap with the effective date, scheduling deserves closer attention. Observably, the certification step can become a gating item for shipment or project acceptance if the relevant test evidence is missing or incomplete. The provided information does not specify detailed transition arrangements, so companies should monitor how timing expectations develop in practice rather than assume a uniform implementation pattern.

Track how customers and market channels update their requirements

The rule change may also appear indirectly through procurement documents, supplier qualification requests, or customer compliance checklists. From an industry perspective, exporters should watch whether U.S.-facing buyers, distributors, or project channels begin asking for clearer proof of OTA efficiency performance in certification materials. The event information does not provide those downstream details, so this remains an area for continued attention rather than a confirmed outcome.

Why this looks more like an execution signal than a distant policy trend

Analysis shows this development is better understood as a concrete compliance change with a defined effective date than as a broad policy direction that still lacks operational form. The key reason is that the update identifies a specific test requirement, a measurable threshold for the 2.4 GHz band, and a reporting obligation inside the certification process. At the same time, it would be premature to treat all implementation consequences as settled, because the provided information does not include detailed enforcement practice, transition handling, or market response.

What deserves closer attention is how this requirement is reflected in actual certification workflows, customer acceptance standards, and supplier selection criteria after October 1, 2026. For affected companies, the immediate issue is less about abstract regulatory signaling and more about whether technical, compliance, and delivery functions can stay aligned under the updated FCC process.

How this update is best understood now

At this stage, the FCC update should be read as a rule change with direct relevance for U.S.-bound RF Module business, especially for Chinese OEM and ODM exporters. The confirmed facts already point to a new certification expectation: mandatory OTA radiation efficiency testing, a stated 45% minimum for the 2.4 GHz band, and explicit disclosure in certification reports. A cautious reading is still necessary, however, because the practical impact on project timing, procurement terms, and market acceptance will depend on how the rule is applied in execution.

In that sense, this is not merely a headline-level policy development. It is more appropriate to understand it as a compliance requirement that has entered the implementation window, while some downstream business effects still need to be observed through actual certification practice and market feedback.

Basis of this article and what still needs verification

This article is generated from the user-provided news title, event date, and event summary. The core factual basis used here is the stated June 28, 2026 FCC release of KDB 996369 D07v07, the mandatory OTA radiation efficiency test for integrated RF Modules, the minimum 45% threshold for the 2.4 GHz band, the requirement to disclose the result in the certification report, and the October 1, 2026 effective date affecting Chinese OEM and ODM exporters to the United States.

For this type of development, commonly relevant source categories would include official regulatory notices, releases from the competent authority, certification guidance documents, standards-related publications, industry association updates, trade administration information, and reporting by established industry media. No specific official source link was provided in the input, so the exact official link still needs to be verified on an ongoing basis. It also remains necessary to continue tracking any later detail on certification interpretation, implementation practice, customer document requirements, tender language, industry feedback, and exporter response.
