BT WiFi Devices Testing

Bluetooth technology is a short-range wireless transmission technology widely used in various electronic products. The Bluetooth specification issued by the Bluetooth Special Interest Group (SIG), the Bluetooth standardization organization, has evolved to Bluetooth v5.3.

JJR Laboratory in China has obtained wireless radio frequency and performance testing authorization qualifications in mULtiple countries and regions. It has built test sites that meet standard requirements and introduced multiple sets of professional testing equipment. Its Bluetooth testing capabilities cover Bluetooth chips and the latest Bluetooth v5.3 version. The professional technical team established can provide customers with mature and comprehensive one-stop solutions for testing and certification, such as OTA performance testing of Bluetooth products.
