Learn how TPMS sensor transmit power is evaluated under FCC Part 15 and ETSI EN 300 220, with clear boundaries between regulatory testing and vehicle validation.
Regulatory path
North American projects commonly evaluate applicable emissions requirements under FCC Part 15. European projects commonly evaluate the applicable band, equipment category and test conditions under ETSI EN 300 220. The exact clauses must be confirmed for the model, frequency and target market.
- Define the market, model and operating frequency.
- Confirm transmit power, bandwidth, modulation, transmission interval and spurious-emission tests.
- Test one consistent hardware, firmware and antenna configuration.
- Retain the test report, labeling, user documents and declaration of conformity.
Key parameters behind transmit power
| Parameter | What to review |
|---|---|
| RF output | Power, frequency and sample consistency against the test requirements. |
| Battery state | Stable transmission during low temperature, low voltage and end-of-life conditions. |
| Antenna and structure | Effects of antenna orientation, rim metal and installation position. |
| Protocol and timing | Packet, modulation, interval and repetition behavior against the receiver. |
Regulatory testing does not replace vehicle validation
Regulatory testing confirms the applicable RF requirements. Vehicle validation confirms whether the installed sensor is reliably identified by the target vehicle or receiver system. Validation may include activation, relearn, wheel-position identification, repeated reception, low-temperature and low-voltage conditions.
Vehicle results apply to the tested vehicle and conditions. They do not replace regulatory testing or establish universal vehicle coverage.
Scope
North America, Europe and other markets requiring applicable radio evaluation.
Sensor model, frequency, hardware or firmware revision, test reports and target vehicle information.
Engineering conclusion
Evaluating TPMS sensor transmit power under FCC Part 15 and ETSI EN 300 220 is an important compliance path for the relevant markets. The certification status of a specific model must be supported by current reports, certificates or declarations and their stated scope.
For a project-specific review, provide the vehicle application, product model, validation objective, target market, drawings, specifications, or manufacturing-readiness requirements.
