BQB authentication is Bluetooth authentication. In short, if your product has Bluetooth function and is marked with Bluetooth mark on the product appearance, it must pass a certification called BQB. For details of the origin and operation form of BQB certification, please refer to the following.



Essence of Bluetooth Technology: a short-range wireless communication standard, which works in ISM frequency band of 2.45GHz (2402-2480mhz), with a total of 79 channels. Each transceiver is equipped with 48 bit address in accordance with IEEE 802 standard, and the data frequency is 1Mbps. Using spread spectrum and frequency hopping technology, its working range is about 10M-100M.



To understand BQB certification, you must first understand Bluetooth SIG (Bluetooth special interest group). In May 1998, Ericsson, Nokia, Toshiba, IBM and Intel, five famous companies in the world, jointly launched the Bluetooth program, which has been responded and supported by many manufacturers. Bluetooth SIG has more than 9000 members, including seven original promoters, including Ericsson, Intel, Lenovo, Motorola, Microsoft, Nokia and Toshiba. In order to better develop Bluetooth technology and ensure the compatibility of interoperability between different devices, Bluetooth SIG has issued the qualification program reference document v2.0 (PRD 2.0 for short) to supervise and control the standard use of Bluetooth technology. Must be a Bluetooth SIG member; the product must be certified in accordance with the Bluetooth qualification process (BQP) to use the Bluetooth logo. This requires that all Bluetooth products must pass BQB certification before they can be sold and used.




BQB certification process




First of all, you must become a Bluetooth SIG member. There are two types of members: Associate paid member (annual fee $7500 is required), and the other type is that adorer does not need paid member. You can apply for different types of members according to specific needs.



Members must complete all steps in accordance with PRD 2.0. Bluetooth certification program is to better ensure the interoperability, verify the consistency with Bluetooth specifications, strengthen the implementation of Bluetooth SIG, correct the abuse of potential Bluetooth trademarks and provide members with a higher test standard to show the stability and quality of their products and other Bluetooth devices working together. The new program through a large number of process automation, so that the time to pass the qualification process and reduce costs at the same time to promote the more effective development of Bluetooth devices.









According to the test type, BQB test includes the following test items



RF Testing



Protocol Conformance Test



Profile Conformance Test



Profile Interoperability Test



All test items are divided into four categories: A, B, C and D. the details are as follows:



The test shall be carried out on test equipment meeting the requirements of the following equipment and the test certificate shall meet the requirements of the certificate.



Because components, chips and modules are pre qualified, only RF and profile tests are required for end products using these components.



For end product, if the component is certified, only RF needs to be tested, and IOP testing is required, even if other profiles are not supported.
