SRRC certification
SRRC certification is the State Radio Regulatory Commission certification. According to the "Administrative Regulations on Imported Radio Transmitting Equipment" and "Administrative Regulations on the Production of Radio Transmitting Equipment", in order to strengthen the management of the import and production of radio transmitting equipment, any radio transmitting equipment exported to the People's Republic of China, or within the territory of the People's Republic of China All radio transmitting equipment produced (including trial production) must hold a "Radio Transmitting Equipment Model Approval Certificate" issued by the State Radio Regulation Committee and SRRC after model approval of its transmitting characteristics.
The model approval code must be marked on the label of the factory equipment. The testing agency currently recognized by the Radio Administration Bureau of the Ministry of Information Industry is: State Radio Monitoring Center (SRMC)

SRRC certified product range:
Mobile communication equipment: 2G/3G base station/terminal/repeater, etc.;
Professional communication equipment: AM transceivers, digital walkie-talkie system base stations/vehicle-mounted stations/handheld stations, analog clusters, digital cluster base stations/handheld stations/repeater stations, digital transmission stations, microwave equipment, satellite earth station equipment, cordless telephone equipment, Bluetooth equipment, maritime satellite equipment, etc.;
Wireless access equipment: 2.4GHz/3.5GHz/5.8GHz wireless access equipment, etc.
Radar navigation equipment: weather radar, navigation radar, speed radar, aviation navigation equipment, etc.;
Radio and television equipment: FM/AM broadcast transmitter equipment, television transmitter equipment;
Short-distance micropower equipment: general micropower equipment, biomedical telemetry equipment, public intercoms, wireless microphones, etc.;
Various other systems containing radio transmitting devices.
In addition to the traditional products above, there are tablets, mobile phones, Bluetooth speakers and other products that contain wifi, BT and data terminal functions.
SAR (Specific Absorption Rate of Electromagnetic Radiation) detection
SAR definition
SAR concept 1: Introduction of SAR concept: Since various organs of the human body are lossy media, induced electromagnetic fields will be generated in the body under the action of external electromagnetic fields. The induced electromagnetic fields in the body will generate current, resulting in the absorption and dissipation of electromagnetic energy. Specific absorption rate SAR is used to characterize this physical process.
SAR Concept 2: Specific Absorption Rate: Specific Absorption Rate
It is defined as the electromagnetic radiation (irradiation) energy absorbed by an organism per unit time (s) and unit mass (kg). Its unit is W/kg.
SAR Concept 3: SAR measurement mechanism:
As can be seen from the definition, SAR evaluation is performed by measuring field strength distribution or temperature changes. However, it is difficult to conduct SAR evaluation by measuring temperature rise, and the error is large. Therefore, electric field probes are currently commonly used internationally to measure field strength distribution for SAR evaluation in order to achieve higher measurement accuracy.
SAR definition: Under the action of external electromagnetic fields, induced electromagnetic fields will be generated in the human body. Since various organs of the human body are lossy media, the electromagnetic field in the body will generate current, resulting in the absorption and dissipation of electromagnetic energy. SAR is commonly used in biological dosimetry to characterize this physical process. The meaning of SAR is the electromagnetic power absorbed or consumed by unit mass of human tissue, in W/kg.

Wireless communications EMC
European Union
In the EU market, the "CE" mark is a compulsory certification mark. Whether it is a product produced by an enterprise within the EU or a product produced in other countries, if it wants to circulate freely in the EU market, it must be affixed with the "CE" mark to indicate that the product Comply with the basic requirements of the EU's "New Approach to Technical Harmonization and Standardization" directive. This is a mandatory requirement imposed by EU law on products.

Radio and communication terminal products, testing and certification include:
1.Electromagnetic compatibility test EMC
2. Safety test LVD (in the new directive, this test is also required for RF products with battery input)
3. Conduct radio communication equipment testing (RF testing) according to European ETSI standards
4. Electrical safety and health protection testing (Health, SAR assessment)
US FCC certification
FCC certification: FCC (Federal Communication Commission, US Federal Communications Commission) was established by COMMUNICATIONACT in 1934 and is an independent agency of the US government. Communication products and digital products require FCC approval to enter the US market. The FCC committee investigates and studies all stages of product safety to find the best way to solve the problem. At the same time, the FCC also includes the detection of radio devices and aircraft.
According to the relevant parts of the U.S. Federal Communications Regulations (CFR Part 47), all electronic products entering the United States need to undergo electromagnetic compatibility certification (except for some products specifically stipulated in relevant provisions). There are three common certification methods: Certification, DoC, Verification. The certification methods and procedures for these three products are quite different. The optional certification methods for different products have relevant regulations in the FCC. The stringency of its certifications decreases.
For these three types of certifications, the FCC Committee also has relevant requirements for each laboratory. Generally speaking, wireless communication products require FCC ID certification. FCCID has a strict application process, which will not be explained in detail here.
