    As the flagship mobile phones of major mobile phone manufacturers cancel 3.5mm audio interfaces, more and more Bluetooth audio products have received market attention. Bluetooth audio products such as Bluetooth headsets, Bluetooth speakers, and Bluetooth headsets, including mobile phones, remote controls, wireless doorbells, and other wireless Bluetooth products are becoming more and more abundant. Wireless electronic products have always had a high degree of attention in the Japanese market. Wireless products need to pass telec certification before they can be sold in Japan. So what test items do Bluetooth products do for telec certification?

    The specific standard for 2.4GHz Bluetooth products is MIC No.88 Annex43. The following are the specific test items we should consider based on the standards, mainly as follows:

    1. Frequency error measurement (Frequency Error Measurement);

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

    3. Unwanted Emission Intensity Measurement;

    4. Antenna Power Error Measurement;

    5. Receiver spurious disturbance test (Limitation of Collateral Emission of Receiver Measurement);

    6. EIRP antenna power test (Transmission Antenna Gain (EIRP Antenna Power) Measurement);

    7.3dB Lobe Bandwidth Test (Transmission Radiation Angle Width 3dB BandwidthMeasurement);

    8. Duty Cycle Measurement (Duty Cycle Measurement);

    9. Occupation time test (retention time);

    10. Interference protection and carrier sense (Radio Interference Prevention Capability & Carrier Sense Capability Measurement).
