FS-FHSS Wireless Simultaneous Interpretation System
FS-FHSS wireless simultaneous interpretation system utilize digital wireless communication and innovated FS-FHSS (Frequency Selecting - Frequency Hopping Spread Spectrum) technology. It comes with super-strong anti-interference capability and broad bandwidth, provides perfect audio quality, and utilizes AES technique to encrypt data. Effective communication distance is 50~500m. Signals can be transmitted out in all directions. Eight channel is configured with one antenna unit, which reduces deployment difficulty and saves system investment.
The system is able to modulate and transmit up to 16 channels at the same time, allowing participants to select a channel to hear the required language so long as he/she has a handheld or headset receiver.
