Wireless bluetooth headset

Bluetooth headset's main RF test standard

Bluetooth devices operate in the ISM band and communicate with each other via Gaussian Frequency Shift Keying (GFSK) digital frequency modulation technology. Time division multiplexing (TDD) is used between devices, and an extremely fast frequency hopping scheme is used to facilitate congestion. Improve link reliability in the band. For the Bluetooth headset, the RF part is one of the main test content.
