The wireless network receiver is abbreviated as WLAN (Wireless Local Area Network), also known as high-power wireless network card, wireless network device. The network card is connected to the USB interface of the computer, and it automatically searches for a large area of wireless networks nearby to realize wireless Internet access. However, if such wireless products want to be sold on the Chinese market, SRRC certification is required.

The wireless communication module is the information portal through which various smart terminals can access the Internet of Things. It is the key link between the perception layer and the network layer of the Internet of Things. At present, in the M2M scenario, more cellular communication modules (2G/3G/4G) are used. In the future, LPWAN modules (NB/loT, LoRa) will be rapidly applied. But generally, if you want to sell this kind of products in our country, you need to apply for CTA access certification?.

Unmanned aircraft is abbreviated as \"unmanned aerial vehicle\", which is an unmanned aircraft operated by radio remote control equipment and self-provided program control device, or it is completely or intermittently operated autonomously by an onboard computer. UAVs are easy to use and have strong timeliness, and they are widely used in various fields of life. However, in general, these products need to be certified by SRRC if they want to be sold on the Chinese market.

With the continuous development of technology, Bluetooth headsets can be seen everywhere in our lives, and they have become a good tool for mobile business people to improve efficiency. But Bluetooth headsets need to apply for CE certification if they want to enter the EU market.

On September 3, 2021, the European Chemicals Agency (ECHA) announced the launch of a public comment on four potential substances of very high concern (SVHC). The comment period will end on October 18, 2021. During this period, all stakeholders All comments can be submitted to ECHA. The approved substances will be included in the SVHC candidate list as official substances.

Mobile hard disk mainly refers to the use of USB or IEEE1394 interface, which can be plugged in or unplugged at any time, compact and portable hard disk storage, which can transmit data with the system at a higher speed. However, in general, these products need to apply for SRRC certification if they want to be sold on the Chinese market. However, in order to avoid detours in the process of applying for SRRC certification, general merchants will conduct SRRC pre-test before doing SRRC certification.

The Bluetooth module is a PCBA board with integrated Bluetooth function, used for short-distance wireless communication, and is divided into Bluetooth data module and Bluetooth voice module according to function. However, in general, Bluetooth BQB certification? is required for such Bluetooth devices to be put on the market.

The Bluetooth keyboard refers to a keyboard that performs wireless transmission through the Bluetooth protocol and performs Bluetooth communication within an effective range (within 10m). In fact, it is a short-distance radio technology. Using \"Bluetooth\" technology, it can effectively simplify the communication between mobile communication terminal devices such as palmtops, notebook computers, and mobile phones. However, in general, such smart products need to be certified by TELEC if they want to export to the Japanese market.
