Wireless Planning & Coordination (WPC) Equipment Type Approval (ETA) is mandatory for wireless products operating in de-licensed frequency bands in India. While the WPC ETA process is considered document-based and relatively simple, many applications still face delays, objections, or rejections due to common mistakes made by applicants.
Understanding these common errors is crucial for manufacturers, importers, startups, and distributors to ensure smooth approval and avoid unnecessary compliance risks.
1. Incorrect or Incomplete RF Test Report
One of the most frequent reasons for WPC ETA application issues is an incorrect RF test report.
Common problems include:
-
Test report not issued by an ISO/IEC 17025 accredited laboratory
-
Missing accreditation scope for the tested frequency band
-
Test report not matching the exact product model
-
Incomplete technical parameters such as frequency range, output power, or modulation
WPC strictly relies on the RF test report to verify compliance with de-licensed bands. Any mismatch or missing detail can result in rejection.
2. Mismatch Between Product Model and Documents
Another major error is inconsistency between the product model number mentioned in:
-
RF test report
-
Product datasheet
-
ETA application form
-
Product label or packaging
Even a small variation in model name (for example, adding or removing a suffix) can cause objections. WPC approvals are model-specific, and any mismatch raises concerns about authenticity.
3. Incorrect Frequency Band Declaration
Applicants often make mistakes while declaring the operating frequency band.
Common issues include:
-
Declaring licensed frequency bands under ETA (ETA applies only to de-licensed bands)
-
Mentioning a broader frequency range than tested
-
Failing to declare multiple frequency bands used by the same device (e.g., Wi-Fi + Bluetooth)
Incorrect frequency declarations can lead to immediate rejection, as WPC closely monitors spectrum usage to avoid interference with critical communication systems.
4. Using Unauthorized or Outdated Technical Datasheets
Submitting outdated or incomplete technical datasheets is another common error.
Problems include:
-
Datasheets not matching the tested version of the product
-
Missing RF specifications
-
Marketing brochures submitted instead of technical datasheets
WPC requires accurate and technical documentation, not promotional material. Any discrepancy creates doubt about compliance.
5. Incorrect Applicant Details
Errors in applicant information frequently delay approvals.
These include:
-
Incorrect company name or address
-
Mismatch between IEC, GST, and company registration details
-
Applying as manufacturer when actually acting as importer
-
Using outdated authorization letters
ETA approval is issued to a specific legal entity. Incorrect applicant details may result in rejection or the need to reapply.
6. Missing Authorization Documents
When an importer or authorized representative applies on behalf of a foreign manufacturer, a proper authorization letter is mandatory.
Common mistakes:
-
Missing authorization letter
-
Letter not signed or stamped by the manufacturer
-
Incorrect product model mentioned in authorization
Without valid authorization, the application is considered incomplete.
7. Failure to Update Product Variants
Many applicants assume that one ETA covers all variants of a product.
This is incorrect if:
-
Frequency band changes
-
Output power changes
-
Hardware version differs significantly
Each RF-relevant variant may require a separate ETA approval. Ignoring this leads to non-compliance risks.
8. Poor Understanding of De-Licensed Band Rules
Applicants often misunderstand de-licensed band conditions such as:
-
Maximum permitted output power
-
Indoor vs outdoor usage restrictions
-
Band-specific limitations
If a device exceeds permitted limits, ETA will not be granted, even if documentation appears complete.
Conclusion
Most WPC ETA application issues arise not from complex regulations but from documentation errors, technical mismatches, and lack of attention to detail. Ensuring accurate RF test reports, correct frequency declarations, consistent model information, and proper authorization documents can significantly reduce the risk of rejection.
By addressing these common errors proactively, businesses can secure WPC ETA approval smoothly, avoid import delays, and ensure lawful sale of wireless products in India.
