Any device that transmits or receives wireless signals in India — from a simple Bluetooth speaker to an enterprise Wi-Fi router — requires regulatory approval before it can be imported or sold. Two separate Indian government bodies oversee these approvals: the Wireless Planning & Coordination Wing (WPC) under the Ministry of Communications, and the Telecommunication Engineering Centre (TEC) under the Department of Telecommunications (DoT).
Understanding which certification applies to your product — and whether you need both — is essential before committing to a product launch timeline in India.
📡 Quick Overview: WPC vs TEC
WPC (Wireless Planning & Coordination)
Governs radio frequency spectrum use. Mandatory for any device with a wireless transmitter operating in licensed or unlicensed frequency bands in India.
TEC (Telecommunication Engineering Centre)
Governs technical standards for telecom equipment interfacing with Indian networks. Mandatory for devices connecting to public telecom networks.
📊 WPC vs TEC: Side-by-Side Comparison
| Parameter | WPC | TEC |
|---|---|---|
| Governing Body | WPC Wing, Ministry of Communications | TEC, Department of Telecommunications (DoT) |
| Scope | Radio frequency transmitting devices | Telecom equipment interfacing with public networks |
| Certificate Type | ETA (Equipment Type Approval) or IML (Import Licence) | TEC Type Approval Certificate |
| Product Examples | Wi-Fi routers, Bluetooth devices, walkie-talkies, drones, IoT modules | IP phones, DSL modems, PSTN equipment, SIM card devices, GSM/LTE terminals |
| Testing | At WPC-approved test labs for RF parameters | At TEC-designated labs against TEC Generic Requirements (GR) |
| Frequency | Based on operating frequency bands | Based on network interface type |
| Validity | Typically 2 years for ETA | Typically 1–3 years |
| Who Needs It | Manufacturers, importers, distributors of RF devices | Telecom equipment manufacturers/importers for network-connected devices |
📶 When Do You Need WPC ETA?
WPC issues two types of approvals: Equipment Type Approval (ETA) and Import Licence (IML). ETA is required for devices with wireless transmitters, while IML may be required for import of certain restricted radio devices. Common products requiring WPC ETA include:
- Wi-Fi routers, access points, and mesh systems
- Bluetooth devices (speakers, headphones, keyboards, mice)
- Cordless telephones and DECT systems
- Drones and unmanned aerial vehicles (UAVs)
- IoT gateway devices and smart home hubs
- Wireless security cameras and CCTV systems
- GPS receivers and trackers with RF capability
- Two-way radios and walkie-talkies
📌 Devices that operate ONLY in the 2.4 GHz and 5 GHz unlicensed ISM bands (like most standard Wi-Fi and Bluetooth products) are eligible for the simplified Self-Declaration ETA pathway — significantly faster and less expensive than the full ETA process.
🔌 When Do You Need TEC Certification?
TEC certification is required for equipment that connects to India's public switched telephone network (PSTN), public land mobile network (PLMN), or other licensed telecom networks. Products requiring TEC approval include:
- VoIP equipment and IP-PBX systems
- ADSL/VDSL modems and broadband gateways
- SIM card based devices (M2M modules, IoT with cellular)
- LTE/5G CPE (Customer Premises Equipment)
- Telecom network infrastructure equipment
- Emergency communication devices
🔄 WPC ETA Application Process
- Identify ETA TypeDetermine whether your product qualifies for Self-Declaration ETA (unlicensed bands) or requires full ETA with lab testing.
- Testing at WPC-Approved LabFor full ETA, submit samples to a WPC-approved test lab for RF parameter testing against WPC technical requirements.
- Apply on WPC Online PortalSubmit application at www.wpc.gov.in with test reports, technical specifications, and product photos.
- WPC ReviewWPC reviews the application and may raise technical queries. Respond promptly to avoid delays.
- Receive ETA CertificateWPC issues the ETA certificate. Mark the WPC approval number on the product and packaging.
🔄 TEC Certification Process
- Identify Applicable TEC Generic Requirement (GR)TEC issues Generic Requirements (GRs) for each equipment category — identify the correct GR for your product.
- Testing at TEC-Designated LabGet the product tested at a TEC-designated test laboratory against the relevant GR parameters.
- Submit Application to TECSubmit the complete application with test reports, technical documentation, and compliance declaration to TEC.
- TEC Technical EvaluationTEC engineers evaluate the application and test reports. Additional samples or clarifications may be requested.
- Receive TEC Type ApprovalTEC issues the Type Approval Certificate. This must be referenced in your customs documentation for import.
⚠️ Do You Need Both WPC and TEC?
Yes — for many modern connected devices. A cellular IoT device, for example, requires WPC ETA (for the RF transmitter) and TEC approval (for connecting to the mobile network). Similarly, a 4G/LTE router needs both certifications. Always map your product's features against both WPC and TEC requirements before starting the certification journey.
