In this tech spotlight, ( Tech Spotlight: Frequency Hopping Spread Spectrum ) we discussed how Frequency Hopping Spread Spectrum (FHSS) works. It was originally invented (around WWII) as a means to prevent jamming of telecommunications and to reduce interference. In in most basic terms, FHSS is a modulation scheme that changes frequency in a pattern known to both the transmitter and receiver. The transmitted data is divided into packets and transmitted to the receiver over numerous hop frequencies. Only transmitters and receivers that are synchronized on the same hop frequency pattern will have access to the transmitted data. While FHSS is a fairly old technology, it has been updated for non-military purposes.
