Which Radio Frequency Bands Are Specifically Regulated Under India's WPC Certification Framework

 A wireless device approved overseas may still face difficulties in India because its channels, transmission power, or operating mode do not match Indian requirements. This can affect routers, smart sensors, remote controls, RFID readers, and connected consumer products. WPC registration starts with understanding the device’s complete radio specifications and comparing them with India’s notified conditions. Several bands permit licence-exempt use, but that permission is conditional. Businesses need to establish the correct approval route before ordering equipment or enabling additional wireless features.

Does WPC regulate only Wi-Fi and Bluetooth bands?

No. The Wireless Planning and Coordination Wing of the Department of Telecommunications deals with spectrum management across many radio services. The National Frequency Allocation Plan identifies allocations, while specific rules and authorizations determine how equipment may operate.

The term WPC registration is commonly used for the application process associated with wireless equipment approvals. For eligible devices in notified licence-exempt bands, Equipment Type Approval is a relevant route. However, an ETA does not authorize unrestricted use of every frequency.

A WPC Certificate must be checked against its actual scope. Equipment operating outside an applicable exemption may require a different spectrum or operational authorization.

Which bands commonly affect commercial devices?

The following ranges are important examples. They are not an exhaustive list of India’s regulated spectrum:

  • 2400–2483.5 MHz: Commonly used by Wi-Fi, Bluetooth, and other low-power wireless products.
  • 5150–5250 MHz and 5250–5350 MHz: Covered by the rules for wireless access systems, including radio local area networks.
  • 5470–5725 MHz and 5725–5875 MHz: Additional ranges covered by the 5 GHz wireless access framework.
  • 5925–6425 MHz: Covered by India’s 2026 rules for specified low-power and very-low-power wireless access systems.
  • 433.05–434.79 MHz: Covered by a low-power radio frequency device exemption.
  • 865–868 MHz: Covered by the short-range device framework, with conditions depending on the device category.

Other notifications address specialized equipment and applications. A product should be assessed against the relevant rule, not simply matched to a familiar band name.

What should businesses check in the 2.4 GHz band?

Although many products use 2.4 GHz, their power levels and antenna configurations can differ considerably. A Bluetooth speaker and an industrial wireless link should not be assumed to have identical compliance requirements merely because both operate within the same range.

Before WPC registration, obtain the manufacturer’s channel list, maximum transmit power, antenna specifications, and RF test report. Confirm that the tested configuration corresponds to the model intended for India.

A WPC ETA Certificate should support the relevant equipment configuration. Overseas approvals can provide useful technical evidence, but they do not independently establish compliance with Indian requirements.

Why does 5 GHz require a careful channel review?

“5 GHz Wi-Fi” describes several separate ranges, not one continuous licence-exempt band. A router’s global configuration may include channels that require different treatment in India.

Check the conditions governing indoor or outdoor operation, radiated power, and interference-management features where applicable. Dynamic Frequency Selection and Transmit Power Control requirements must be considered for the relevant range and equipment.

The WPC registration review should also examine firmware and regional settings. A compliant test report is insufficient if the supplied device operates with a different channel or power configuration. Preserve evidence that the Indian configuration matches the approved technical position.

What changed for the lower 6 GHz band?

India’s 2026 notification permits specified low-power indoor and very-low-power outdoor wireless access systems in 5925–6425 MHz, subject to technical and operational conditions. It does not open the entire international 6 GHz Wi-Fi range for unrestricted use.

Businesses should check device category, power limits, antenna requirements, and operational restrictions. The notified conditions include restrictions relating to drone communication and control.

DoT has also issued instructions concerning equipment capable of using this range but previously certified only for 2.4 GHz or 5 GHz. Manufacturers and importers should review those instructions when assessing whether an existing WPC Certificate needs replacement. A previous WPC ETA Certificate should not automatically be treated as covering newly enabled 6 GHz operation.

What about 433 MHz and 865–868 MHz devices?

Remote controls, telemetry equipment, RFID systems, and sensors may use sub-GHz frequencies. The notified 433.05–434.79 MHz range and 865–868 MHz short-range device framework have their own limits and conditions.

For 865–868 MHz, examine the category-specific provisions, including applicable power, bandwidth, and transmission-duty requirements. Do not assume that a device designed for another country’s sub-GHz allocation is suitable for India.

WPC registration should begin before selecting the regional radio module. Replacing an unsuitable module after production can affect testing, documentation, and delivery schedules.

Which documents help establish the right approval route?

Prepare a technical file containing:

  • Product and model identification.
  • Complete transmitting frequency ranges and channel settings.
  • RF test reports relevant to the supplied configuration.
  • Maximum output power, antenna gain, and radiated-power information.
  • Intended installation and operating environment.
  • Manufacturer declarations and applicant authorization documents.
  • Existing approval details and evidence of material changes.

Also check the import classification and applicable approval procedure. A WPC Certificate does not replace separate BIS, telecom testing, or other product requirements where those apply.

How can ASC Group help?

ASC Group can assist with WPC registration, frequency assessment, RF report review, and identification of the relevant application route. Its team can help businesses compare proposed equipment specifications with notified Indian conditions before procurement or shipment.

Support for a WPC ETA Certificate should also include checking model identity and whether the evidence covers all relevant radio functions. By coordinating the technical file and WPC Certificate requirements early, businesses can reduce avoidable application queries and make better decisions about products intended for the Indian market.

What is a Provisional Duty Bond & Special Valuation Branch?

When importing goods into India, businesses often encounter valuation complexities, especially in transactions involving related parties. To address such concerns, the Special Valuation Branch (SVB) of Indian Customs evaluates related-party transactions to ensure fair pricing and prevent duty evasion. One of the key requirements in the SVB process is the Provisional Duty Bond (PDB) . Understanding the Provisional Duty Bond A Provisional Duty Bond is a financial guarantee provided by importers undergoing SVB customs investigation. Since the final duty assessment may take time, the bond ensures that the government does not face revenue losses due to under-valuation. This bond is typically accompanied by a bank guarantee as additional security. Purpose of a Provisional Duty Bond: Allows clearance of goods while SVB verification is in progress. Ensures the customs department recovers any additional duty, if applicable. Acts as a safeguard against potential under-declaration of ...
