Radio speaking unit BW12C/D

With the antenna diversity technology, DSSS modulation has high anti-interference within the transmission frequency range of 2.4/5.2/5.8ghz. If the interference frequency system automatically switches the frequency band during the meeting, the signal communication between the host and the terminal unit adopts the wireless base station mode for voice data interaction to ensure that the audio delay is less than 10ms.

Each terminal unit has the function of wireless transceiver and relay, and the network between terminal unit and terminal unit can ensure the data is not lost. The audio sampling frequency is up to 48Khz, and the frequency response of speech unit is up to 30Hz-20KHz, similar to the effect of CD sound quality.

Qtrf-derfi digital electromagnetic radio frequency anti-jamming technology of qituo has carried out new anti-jamming algorithm, advanced circuit design and overall optimized shielding deployment for transmission signal, breaking through the traditional technology, providing more excellent anti-jamming shielding ability, effectively avoiding mobile phone, WiFi, Bluetooth, radar, wireless signal, microwave signal and complex machine room ring Environment and other electromagnetic interference.
