FS-FHSS 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

♦ Gonsin innovated FS-FHSS (Frequency Selecting-Frequency Hopping Spread Spectrum) technology
♦ Highly flexible for conference places, suits various conference places including outdoor/ indoor/ temporary/fixed conference place
♦ AES for data encryption, preventing malicious interference and listening
♦ Super-strong anti-interference capability, being immune to any light source, wireless communication equipment, and signal jammer
♦ Adjustable transmission power, the effective communication distance could reach from 50m to 500m.
♦ Unlimited system capacity within the effective transmission scope, suitable for small/medium/large/super-large conferences
♦ All-direction transmission, allowing participants to move within the effective transmission scope
♦ Max number of simultaneous interpretation channels in one system: 8; in support of cascading, max number of simultaneous interpretation channels: 16
♦ Simultaneous interpretation server GONSIN30000I could be connected to DCS-3021 wireless discussion terminal to extend conference discussion function.

♦ One system just requires one wireless access point, which makes the deployment simple and applicable.
