FHMA (Frequency-hopping Multiple Access)

Spread-spectrum transmission technology that enables simultaneous data or voice communications to share the same communication medium by causing transmitting and receiving stations to change the frequency rapidly in a pseudorandom sequence among many discrete radio channels. Transceivers are synchronized using a hopping sequence calculated from a predefined algorithm. This sequence can be adjusted dynamically to avoid other transmissions and interference in the same frequency band.
