With antenna diversity technology, DSSS modulation ensures 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 frequency delay is less than 10ms. With the technology of intellectual property rights owned by qituo, each terminal unit has the function of wireless transceiver and relay. The network between the terminal unit and the terminal unit can ensure that 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. Qituo's qtrf-derfi digital electromagnetic radio frequency anti-interference technology has carried out new anti-interference algorithm, advanced circuit design and overall optimized shielding deployment for transmission signals, breaking through the traditional technology, providing more excellent anti-interference shielding capability, effectively avoiding mobile phones, WiFi, Bluetooth, radar, wireless signals, microwave signals, and complex computer rooms Environment and other electromagnetic interference.
