Wireless Simultaneous Interpretation System
FS-FHSS Wireless Simultaneous Interpretation System
FS-FHSS wireless simultaneous interpretation system utilize digital wireless communication and Gonsin innovated FS-FHSS( Frequency Selecting - Frequency Hopping Spread Spectrum) technology. It comes with super-strong anti-interference capability and broad bandwidth, provides perfect CD-level 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.
* FS-FHSS( Frequency Selection –Frequency Hopping Spread Spectrum) technology:Frequency hopping communication technology is a common spread spectrum communication technology which is widely applied to various wireless communication fields. GONSIN has developed the unique FS-FHSS based on this communication technology. The new technology can monitor and select the undisturbed frequency band. FS-FHSS ensures the stability of the communication. It is applied to GONSIN wireless conference system, which implements the discussion, simultaneous interpretation, voting and others comprehensive conference application functions.
Features
♦ One system just requires one wireless access point, which makes the deployment simple and applicable.
