because 2.4GHz It's a kind of engineering medicine without license （ISM） Frequency band , So it's also the most widely used 、 One of the most crowded frequency ranges , Typical 2.4GHz The product has Bluetooth （Bluetooth）,WIFI, Cordless telephone , wireless MIC etc. . This kind of product applies to Japan MIC（ It's also called radio wave or TELEC） Specific tests required by Certification .

MIC Requirements are mandatory certification requirements for wireless products in Japan , It is similar to the domestic model approval for wireless products （SRRC） requirement . It follows the upper law of Japan radio wave law . The specific test specification is to follow the Ministry of general affairs of Japan （MIC） Notice 88 Regulation No , The update and maintenance of the test specification is also carried out by the Ministry of general affairs of Japan .

It's about 2.4GHz The specific standard of Bluetooth products is MIC No.88 Annex 43. The following is a list of specific test items that should be considered according to the standard , Mainly as follows ：

1、 Frequency error test （FrequencyError Measurement）;

2、 Coupling bandwidth / Carrier frequency bandwidth test （Occupied Bandwidth and Spread-spectrum Bandwidth / Factor）;

3、 Stray disturbance test （UnwantedEmission Intensity Measurement）;

4、 Antenna power error test （AntennaPower Error Measurement）;

5、 Receiver spurious disturbance test （Limitationof Collateral Emission of Receiver Measurement）;

6、EIRP Antenna power test （TransmissionAntenna Gain (EIRP Antenna Power) Measurement）;

7、3dB Lobe bandwidth test （TransmissionRadiation Angle Width 3dB Bandwidth Measurement）;

8、 Duty cycle test （DutyCycle Measurement）;

9、 Take time to test （retentiontime）;

10、 Interference protection and carrier interception （RadioInterference Prevention Capability & Carrier Sense Capability Measurement）.

In Japan, MIC Certification is for WIFI Of 2.4G requirement , The specific test items are similar to Bluetooth products , But it needs to be pointed out that it is aimed at 2.4GHz WiFi Of the product 14 channel （Channel14：2471〜2497MHz）, In Japan, TELEC It needs to be used separately in authentication Annex 44 Standard for testing and reporting .

For the above Certification , If you still have questions , Welcome to leave a message to discuss with each other , Together to promote ！
