Wireless Device Testing in India: RF, SAR, EMC & Safety Tests for WPC, TEC and FCC

Bluetooth speakers, smart watches, Wi-Fi cameras and IoT sensors all have one thing in common: before they can be sold, they must be tested as radio products. The tests feed approvals such as WPC ETA and TEC in India, FCC in the US and CE in Europe.

This guide explains the four groups of wireless testing, which approvals use them and how to plan testing so you do not pay twice.

The Four Groups of Wireless Testing

Test group	What it checks	Typical standards
Radio (RF)	Output power, frequency, occupied bandwidth, spurious emissions, receiver performance	ETSI EN 300 328 and EN 301 893 (EU), FCC Part 15C and 15E (US)
RF exposure	SAR for devices used close to the body, or MPE calculation for others	IEC/IEEE 62209-1528, FCC KDB guidance
EMC	Emissions and immunity of the whole device	ETSI EN 301 489 series, CISPR 32 and CISPR 35
Electrical safety	Shock, fire and heat hazards	IEC 62368-1, IS 13252 (Part 1) in India

Which Approvals Use These Tests

WPC ETA (India)

Products using de-licensed frequency bands, such as 2.4 GHz and parts of 5 GHz, need Equipment Type Approval from the WPC. Most go through the self-declaration route, which needs an RF test report from an accredited lab. See WPC ETA documents required.

TEC (India)

Telecom products notified under the Mandatory Testing and Certification of Telecom Equipment (MTCTE) regime, such as routers, smartphones and IoT gateways, must be tested in TEC-designated labs to TEC's Essential Requirements, which cover EMC, safety, technical and sometimes security. See our TEC approval service.

BIS CRS (India)

Many wireless products are also notified electronics under CRS, such as Bluetooth speakers, smart watches and power banks. They need safety testing in a BIS-recognised lab. See our CRS guide.

FCC (USA)

Transmitters need FCC certification, using RF, RF exposure and Part 15B tests from an FCC-recognised lab. See FCC certification cost and requirements.

CE and UKCA (Europe and UK)

Radio products fall under the Radio Equipment Directive or the UK radio regulations. They need RF, EMC, safety and RF exposure assessment, usually through self-declaration.

SAR Testing

Specific Absorption Rate (SAR) testing measures RF energy absorbed by the body. It applies to phones, tablets, smart watches, earbuds and other devices used close to the body.

• India: 1.6 W/kg averaged over 1 gram of tissue for mobile handsets
• United States: 1.6 W/kg over 1 gram for head and body
• Europe: 2.0 W/kg over 10 grams for head and body

Low-power devices may qualify for an exemption based on output power and distance, using a calculation instead of a full SAR test.

How to Plan Wireless Testing

1. List target markets and approvals. India only, or India plus the US and EU?
2. List every radio, frequency band and power level.
3. Check module certifications if you use pre-certified modules.
4. Build one test plan that covers all markets, so one set of samples and one lab visit serve several approvals.
5. Prepare samples: normal units plus units with test firmware that can set channels and power for RF testing.
6. Run pre-compliance for EMC and RF where budget allows.

Cost and Timeline

Cost depends on the number of radios, the number of markets, whether SAR is needed and how many models are covered. A single Bluetooth product for India only costs far less than a Wi-Fi plus LTE device for India, the US and the EU. Get a test plan and quote before sending samples.

For time, plan on two to four weeks for RF, EMC and safety on one product. SAR, TEC testing and retests after failures add time.

Common Mistakes

• No test firmware. Labs cannot test RF without a way to fix channels and power.
• Testing for one market at a time. This often repeats the same tests.
• Assuming a certified module is enough. The final product still needs testing.
• Changing the antenna after testing. This can invalidate RF and SAR results.

How Instacertify Helps

We build a single test plan across WPC, TEC, BIS, FCC and CE, coordinate testing in accredited and designated labs and file the approvals. See our wireless testing services and WPC ETA approval service.
