♦ DCS-3021 wireless discussion terminal could be connected to GONSIN30000I congress server and the corresponding wireless AP directly, the system could realize discussion and simultaneous interpretation function.
* 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.
