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.Congress Terminal
