WPC ETA for drones in India sits at the intersection of telecom regulation and civil aviation compliance under the complete drone laws in India guide. The Wireless Planning and Coordination Wing of the Department of Telecommunications issues the approval through the Saral Sanchar portal under the Indian Telegraph Act, 1885. Drone applications cost ₹10,000 per model through Bharatkosh and run through Regional Licensing Office scrutiny rather than self-declaration. The approval feeds directly into the DGFT-WPC-DGCA triple-lock that governs every civilian unmanned aircraft entering Indian airspace.
Why WPC ETA matters for civilian drones
WPC ETA for drones in India shifted from a niche telecom approval into a frontline aviation gate. The change followed the Drone Rules, 2021 taking effect (Ministry of Civil Aviation, 25 August 2021). Every civilian drone carrying wireless hardware must now pass RF scrutiny before drone type certification, commercial deployment, or import clearance.
The Directorate General of Foreign Trade tightened the chain further through Notification No. 54/2015-2020 on 9 February 2022 (DGFT Notification No. 54/2015-2020, 9 February 2022). The notification prohibited imports of completely built, semi-knocked-down, and completely knocked-down drones except for government entities, defence organisations, recognised educational institutions, and research activities.
The statutory ground shifted again on 1 January 2025 when the Bharatiya Vayuyan Adhiniyam, 2024 came into force through Notification S.O. 5646(E) (Ministry of Civil Aviation, 31 December 2024). The 2024 Act replaced the Aircraft Act, 1934. It is now the parent statute for the Drone Rules, 2021 as amended by the Drone (Amendment) Rules, 2024 (G.S.R. 515(E), 21 August 2024).
Wireless approval continues to run under the Indian Telegraph Act, 1885. The Act empowers the Department of Telecommunications and the WPC Wing to license every radio device operating in India. Aviation law decides whether the aircraft can fly. Telegraph law decides whether its radios can transmit. A missing RF report or antenna mismatch now delays customs, drone import authorisation, and eGCA UIN registration simultaneously.
Locating ETA inside India's drone compliance stack
Equipment Type Approval certifies that a drone's wireless communication hardware operates inside India's authorised spectrum parameters. The certificate carries model-level scope, not unit-level scope. One ETA covers every airframe of that model produced without alteration, but does not transfer to a redesigned variant.
The approval is one layer in a four-layer civilian drone compliance chain. ETA validates the radio stack under WPC review. The DGCA Type Certificate validates airworthiness under Rule 7 of the Drone Rules, 2021. The Certification Scheme for Unmanned Aircraft Systems (CSUAS) runs the testing and inspection workflow. CSUAS was notified by the Quality Council of India on 26 January 2022 (Quality Council of India, CSUAS Framework). DGFT authorisation validates legal import. The eGCA platform issues the Unique Identification Number for every airframe.
Approval | Issuing authority | Primary purpose | Trigger point |
|---|---|---|---|
Equipment Type Approval | WPC Wing, DoT | RF spectrum compliance | Before Type Certification |
Type Certificate | DGCA | Airworthiness validation | Before commercial deployment |
Import authorisation | DGFT | Drone import approval | Before customs clearance |
UIN registration | DGCA eGCA | Aircraft identity | Before flight operations |
Form D-1, the Type Certificate application under the Drone Rules, 2021, will not progress past initial document verification without an ETA reference in the radio-stack annex. ETA therefore sits first in the sequence for domestic manufacturers. Importers carrying ETA still face the second-stage DGFT clearance under drone categories in the Drone Rules 2021.
Why drones are excluded from ETA self-declaration
The WPC ETA self-declaration drone exemption is the least understood compliance fact in the Indian unmanned aircraft ecosystem. The confusion comes from a real reform that left drones on the older route.
The Department of Telecommunications introduced ETA via self-declaration through Office Memorandum No. ETA-WPC/Policy/2018-19 dated 26 February 2019, with the Saral Sanchar online facility going live on 12 April 2019 (Department of Telecommunications, OM No. ETA-WPC/Policy/2018-19). The reform allowed wireless devices in de-licensed frequency bands and under the DGFT Free import category to obtain ETA without scrutiny review. Applicants uploaded documents and a fee receipt, and downloaded the certificate from the portal.
The notice explicitly listed four product categories outside that route: radar, jamming devices, drones, and satellite equipment. For drones and other unmanned aircraft, the WPC clarification confirmed that "issuance of ETA through RLOs of WPC Wing shall continue" (Department of Telecommunications, WPC FAQ on ETA).
The Department of Telecommunications widened the self-declaration framework again on 9 September 2024 through Office Memorandum No. R-11017/01/2018-PP(part-1), extending the route to all wireless equipment licence-exempted under Gazette notifications (Department of Telecommunications, 9 September 2024). Drones still did not move. Civilian unmanned aircraft fall under the DGFT Restricted import category, not the Free category, and stay on the scrutiny-based ETA pathway at the Regional Licensing Office.
The structural reason is operational. Drones combine wireless emission with airborne mobility, telemetry, command links, video downlinks, and navigation aids in one airframe. The WPC Wing therefore evaluates every RF parameter through laboratory validation rather than document-only declaration.
De-licensed frequency bands for Indian drone systems
Civilian drone command and video links in India operate on four de-licensed frequency bands notified by the Department of Telecommunications through Gazette notifications. The bands carry no per-user spectrum licence, but every device transmitting on them still requires ETA.
Frequency band | Typical drone use | Maximum power | Regulatory status |
|---|---|---|---|
2.400 to 2.4835 GHz | Command, telemetry, video | ISM low-power limits | De-licensed |
5.150 to 5.350 GHz | Indoor wireless links | Indoor use, low power | De-licensed |
5.825 to 5.875 GHz | Drone command and video links | 1 W transmitter, 4 W EIRP | De-licensed |
865 to 867 MHz | Telemetry and short-range | 1 W transmitter, 4 W ERP | De-licensed |
The 5.825 to 5.875 GHz allocation is the band the WPC Wing notified specifically for outdoor low-power wireless equipment relevant to civilian drone systems. Transmitter output is capped at 1 watt or 30 dBm in a spread of 10 MHz or greater. EIRP is capped at 4 watts or 36 dBm peak (Department of Telecommunications, Gazette Notification on De-licensed Wireless Equipment). The 865 to 867 MHz band, originally notified for RFID applications, also carries 1 watt transmitter and 4 watt ERP ceilings under low-power short-range device rules.
Civilian drones manufactured in India generally combine 2.4 GHz for command-and-telemetry uplinks with 5.8 GHz for video downlinks. The WPC Wing validates antenna gain, occupied bandwidth, transmitter power, and EIRP against the laboratory RF test report. Inconsistent gain declarations remain the leading rejection trigger in scrutiny review.

Documents required for a WPC ETA drone application
A drone ETA submission carries a packet of organisational documents, technical declarations, and laboratory evidence. Missing or inconsistent entries account for the bulk of rejection cycles at the Regional Licensing Office. The drone ETA documents India set breaks into two streams: applicant-side records and product-side records.
Document | Purpose | Status |
|---|---|---|
Company PAN and GST registration | Applicant identity | Mandatory |
Authorised signatory ID and address | Application authentication | Mandatory |
Product datasheet and block diagram | Hardware and RF configuration | Mandatory |
RF test report (NABL or ILAC accredited) | Spectrum compliance evidence | Mandatory |
Antenna gain and EIRP declaration | Power and emission verification | Mandatory |
Bharatkosh payment receipt | ETA fee confirmation | Mandatory |
Signed Saral Sanchar application form | Submission authentication | Mandatory |
Authorized Indian Representative letter | Foreign manufacturer authorisation | Conditional |
Import Export Code | Customs and DGFT linkage for importers | Conditional |
The drone RF test report NABL accredited requirement is the heart of the packet. RF reports must come from an NABL-accredited Indian laboratory or an ILAC or ISO/IEC 17025 accredited foreign laboratory (WPC FAQ on RF Test Report). The report must include transmitter power, antenna gain, occupied bandwidth, modulation details, and laboratory-measured EIRP for every RF module on the airframe.
Drones with multiple RF modules require a separate RF test report for each module. A typical example carries a 2.4 GHz command radio, a 5.8 GHz video transmitter, and a separate GNSS module. A single composite report covering only the primary radio is the leading technical rejection in WPC review.
The Authorized Indian Representative drone ETA requirement applies to every foreign manufacturer without an Indian branch or liaison office. The representative becomes the accountable Indian entity for regulatory communication, clarification cycles, and customs coordination during scrutiny.
The Saral Sanchar drone ETA workflow, step by step
The how to apply for WPC ETA for drones in India workflow runs through the Saral Sanchar portal at saralsanchar.gov.in. The portal is the digital interface of the Department of Telecommunications for wireless approvals. Drone applications follow the scrutiny-based route through the Regional Licensing Office.
The standard sequence runs eight stages:
- Register an organisational account on Saral Sanchar at saralsanchar.gov.in. Login credentials arrive on the registered mobile number and email after OTP verification.
- Complete the applicant profile with PAN, GST, authorised signatory details, and address records.
- Select the ETA application module under WPC services and choose the scrutiny-based route for drones and RPAS.
- Upload the RF test report, product datasheet, antenna declaration, technical block diagram, and Authorized Indian Representative letter where applicable.
- Pay ₹10,000 per drone model through Bharatkosh under the purpose head "Equipment Type Approval (ETA)" to PAO 077188-CCA Headquarters (Department of Telecommunications, Bharatkosh Payment Instructions for ETA).
- Upload the Bharatkosh payment receipt as a separate document inside the Saral Sanchar packet.
- Generate the application PDF from Saral Sanchar, sign it, scan it, and upload the signed version to complete submission.
- Track the application through the Regional Licensing Office, respond to clarification queries, and download the digitally authenticated ETA certificate after approval.
The WPC ETA timeline drone India processing window typically runs 25 to 45 working days from complete submission when the RF documentation aligns with the declared hardware. Multi-module drones, ambiguous antenna declarations, and Bharatkosh payment receipts uploaded outside the document panel extend timelines into the 60-day range and beyond.
Once issued, the ETA certificate is downloadable as a PDF with QR-code authentication. The same ETA can be referenced by subsequent importers of the unaltered model without re-paying the fee (WPC FAQ on ETA Reuse).
WPC ETA fee for drones, validity, and renewal rules
The WPC ETA fee for drones in India is ₹10,000 per model. Applicants pay through Bharatkosh under the "Equipment Type Approval (ETA)" purpose code (Department of Telecommunications, Bharatkosh Payment Instructions for ETA). The fee covers one model regardless of the number of RF modules inside the airframe. Each model requires its own application even where the radio stack is identical.
The WPC ETA validity period drone framework runs on a "valid while unmodified" rule rather than a fixed expiry. The official WPC clarification states that there is no period restriction for ETA. No renewal applies as long as the approved model is manufactured without alteration (Department of Telecommunications, WPC FAQ on ETA). Some commercial certifiers report a five-year validity figure, but this conflates ETA with the broader Wireless Operating Licence framework. ETA itself has no expiry while the model design is unchanged.
Fresh ETA becomes necessary whenever the manufacturer alters any wireless parameter. Changes to the RF chipset, antenna design, antenna gain, transmitter power, occupied bandwidth, or operating frequency trigger a new application. The existing RF validation no longer reflects the current hardware. Cosmetic changes that do not affect the radio stack do not trigger fresh ETA.
The validity rule reads differently against the other layers of drone compliance.
Approval | Validity structure | Renewal trigger | Fee |
|---|---|---|---|
WPC ETA | Valid while hardware is unchanged | Any RF parameter change | ₹10,000 per model |
DGCA Type Certificate | Tied to airframe configuration | Design or category change | As per DGCA schedule |
UIN registration | Tied to airframe lifecycle | Ownership transfer, destruction | ₹100 per Schedule II |
Remote Pilot Certificate | 10 years under Drone Amendment Rules | Expiry, retraining | RPTO training fee |
The WPC ETA vs DGCA Type Certificate distinction is operationally important. ETA approves the radio stack at the model level under telegraph law. The Type Certificate approves the airframe at the design level under aviation law. The two approvals together, not either alone, satisfy the drone insurance providers in India underwriting checks for commercial coverage.
How imported drones route through DGFT, WPC, and DGCA
The WPC ETA for imported drones DGFT workflow runs through three independent authorities, each governing a separate regulatory domain. Importers who treat the chain as a single window lose time at every handover.
The DGFT restricted civilian drone imports through Notification No. 54/2015-2020 issued on 9 February 2022 (DGFT Notification No. 54/2015-2020, 9 February 2022). The notification placed drones in the Restricted category of the EXIM policy, with exemptions limited to government entities, defence organisations, recognised educational institutions, and R&D activities. Commercial operators outside those categories cannot import drone airframes off the shelf.
The compliance sequence for an importer eligible under one of the carve-outs runs in four stages. ETA approval clears the radio stack at the WPC Regional Licensing Office. Without ETA, customs holds the consignment because the radio stack lacks telecom authorisation. DGFT authorisation then clears the import itself. A separate WPC import licence is also required because drones fall in the Restricted EXIM category (WPC Wing Compendium of Orders, 6 July 2022).
DGCA Type Certification clears the airframe for commercial deployment under Rule 7 of the Drone Rules, 2021 through the CSUAS framework. The eGCA platform then clears the airframe for flight by issuing the UIN and linking it to NPNT firmware on DigitalSky. The NPNT and permission artefact cluster covers the cryptographic flight authorisation that follows.
Foreign manufacturers without an Indian branch office must appoint an Authorized Indian Representative before the ETA filing. The representative is the accountable Indian entity for every clarification cycle, customs interaction, and compliance audit.
Common rejection reasons and how to avoid them
Drone ETA rejections cluster around six recurring failure modes at the Regional Licensing Office, each preventable at the documentation stage.
The leading trigger is missing RF coverage on a multi-module airframe. A drone with a 2.4 GHz command radio, a 5.8 GHz video transmitter, and a separate telemetry module needs three RF test reports, not one. Composite reports covering only the primary radio fail on first review.
Antenna gain mismatch is the second recurring trigger. The declared gain on the application must match the laboratory report and the product datasheet. A 5 dBi declaration against a 7 dBi tested antenna creates an automatic clarification cycle.
EIRP overshoot is the third. Transmitter output combined with antenna gain must stay under the 36 dBm ceiling for the 5.825 to 5.875 GHz band, with equivalent ceilings on other de-licensed bands.
Bharatkosh receipt routing is the fourth. The ₹10,000 receipt must upload as a separate document inside the Saral Sanchar packet, with the product name in the Remarks field at payment.
Model number mismatch is the fifth. The identifier on the datasheet, RF test report, antenna declaration, and Saral Sanchar application must match character-for-character. Minor variants ("X-300" against "X300") create rejection.
The sixth applies only to foreign manufacturers. Filing without the Authorized Indian Representative letter forces the application back to step one once the RLO identifies the foreign origin.
The fastest approvals happen when every RF parameter, every model identifier, and every document upload aligns across the packet from the first submission.
What changes under the Civil Drone Bill and the 2024 Act
India's drone regulatory architecture is moving toward tighter integration of telecom and aviation compliance, but the WPC ETA process itself stays stable in the near term.
The Bharatiya Vayuyan Adhiniyam, 2024 already provides the statutory umbrella. The Adhiniyam empowers the Central Government to frame consolidated rules for unmanned aircraft, including design, manufacture, possession, operation, and import. The umbrella is in place, the consolidated rules are still in development.
The Ministry of Civil Aviation issued a consultation draft on the Civil Drone (Promotion and Regulation) Bill on 16 September 2025 (Ministry of Civil Aviation, 16 September 2025). The draft examines single-window approval structures and tighter integration between aviation and telecom workflows. Whether wireless approval becomes a sub-process inside Type Certification, or remains a separate WPC review feeding into the DGCA workflow, is the open policy question.
The core ETA architecture stays unchanged. The ₹10,000 Bharatkosh fee, the NABL-accredited RF test report requirement, the Regional Licensing Office scrutiny route, and the four-product self-declaration exclusion all remain. Manufacturers and importers should plan compliance timelines around the existing architecture rather than anticipated reforms.
Once ETA is in hand, the operator moves to Form D-1 Type Certification under Rule 7 and DGFT authorisation for imported airframes. After that come eGCA UIN issuance, NPNT firmware compliance, and the first DigitalSky permission artefact on the Indian drone airspace zone map. The Remote Pilot Certificate clears the operator side of the same chain.
