Wireless USB adapters Japan TELEC certification

Introduction to telec Certification in Japan

The Radio Act requires certification of types of radio equipment (i.e. conformity certification of technical regulations). Certification is mandatory and the certification body is a registered certification body within the range of radio equipment recognized by mic. Telec(Telecommunication Engineering Center) is the main registration and certification body for radio equipment conformance certification in Japan.

Telecommunication certification standard

For technical standards for certification, refer to the classification and technical standards of radio equipment listed in the certification system of Technical regulations. It is important to note that where these technical standards differ from the technical requirements of the Radio Regulations (No. 18), the Radio Regulations shall prevail.

Authentication type

Telecom certification includes test certification and type certification. Test authentication is to verify each device unit, and the authentication is only valid for each verified device unit. Type certification refers to the validation of a batch of equipment samples with the same design and manufacture. This certification is valid for this lot of equipment, but if the design or manufacture of the equipment changes, the equipment will need to be recertified.

It is important to note that the use of non-low-power radio stations and their terminal equipment requires a licence from mic.

In addition, there are two types of telecom terminal equipment conformance certification:

For ordinary telephone equipment, as long as the requirements of the Telecommunications Act for jate certification;

For wireless terminal equipment, in addition to jate certification according to the requirements of the telecommunications Act, Telec certification is also required according to the requirements of the Radio Act.

Telec authentication for wireless LAN and Bluetooth products

Telec is Japan's mandatory certification for wireless products, somewhat similar to srrc. It follows the Japanese radio wave law. The specific test specification is in accordance with mic Announcement No. 88. See the link below. The update and maintenance of test specifications are also performed by mic.

The test program for wifi and Bluetooth products is basically similar to the European standard en300328.

Among them, 2.4ghzwifi products (802.11b/g, 2412~2472mhz) and Bluetooth products are annex43 mic notice No. 88, but for the 14 channels of 2.4ghzwifi products (Channel 14: 2471 ~ 2497 MHz), annex44 alone needs to be used for testing and reporting, and the corresponding cost needs to be increased.

What are the content and requirements of the mic Certification (telec) test for Bluetooth products in Japan? (Certification consultation: 18165794465)

Frequency error measurement (frequency error measurement)

Coupling bandwidth/carrier frequency bandwidth test (replication bandwidth and spread spectrum bandwidth/factor)

3 Stray interference test (measurement of excess interference intensity)

4. Measurement of antenna power error.

5. Receiver stray interference test (cooperative interference limit of receiver measurement).

6.eirp antenna power measurement (transmitting antenna gain).

7.3 Measurement of db lobe bandwidth (transmitted radiation Angle width (3db beam width))

8. Duty cycle measurement

9. Retention time (retention time)

Technical data required for telec authentication

1. English description of the product

2. Circuit schematic diagram of the product

3. Product circuit diagram and block diagram

4. Product bom(Parts list)

5. Instruction manual

6. Additional required information

Telec authentication period

telec certification for regular products takes 3-4 weeks, depending on the complexity of the specific product, provided that technical documentation and information for product testing are available.
