* 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.
