Missing or inadequate documentation is the leading cause of ETA delays and rejections.

Yes, if the test reports are from ILAC-accredited laboratories and cover Indian WPC requirements. However: Test frequencies must include Indian bands; power limits must be shown for Indian regulations; spurious emission limits should meet WPC specs. Some products may need supplemental India-specific testing. Always verify with your lab that they included WPC parameters. ### What is the validity period of RF test reports? WPC typically accepts RF test reports within 1 year of the test date. Older reports may be rejected. If product design or firmware has changed since testing, new testing may be required. Maintain test report continuity for product variants. ### Do I need separate ETA for each product variant? If variants have identical RF characteristics (same frequency bands, power levels, antenna, modulation), one ETA may cover multiple variants with clear documentation. If RF parameters differ (different bands, different power), separate ETA applications are required. Cosmetic variants (color, minor form factor) can typically share ETA. ### What if my product fails WPC testing? If pre-submission testing shows non-compliance: modify product hardware/firmware to meet limits; retest at accredited lab; submit new test report. If WPC finds issues during review: they may request clarification or additional testing; worst case - application rejection requiring redesign. ### Is software-defined radio (SDR) treated differently? Yes, SDR devices with programmable frequencies require additional documentation: SDR declaration stating frequency/power cannot exceed authorized limits via software; security measures preventing unauthorized modification; possibly additional testing. SDR adds complexity to ETA process. **Disclaimer:** This guide reflects current WPC ETA documentation requirements under Indian Telegraph Act.
