WebThe Bottom Line. It strikes me that, as the 2.4GHz band becomes more congested with RC fliers, the number of problems being experienced by DSSS fliers seems to be also increasing disproportionately to the number of those systems in use. Theory makes it clear that a constantly agile system (FHSS) should be more resilient to noise on the band and ... WebFrequency-hopping spread spectrum (FHSS) transmission is the repeated switching of frequencies during radio transmission to reduce interference and avoid interception. It is useful to counter eavesdropping, or to obstruct jamming of telecommunications. And it can minimize the effects of unintentional interference.
