FDM and FHSS
Frequency Division Multiplexing (FDM) divides the available frequency spectrum into non-overlapping bands, assigning each band to a separate signal for simultaneous transmission, maximizing bandwidth efficiency.
Frequency Hopping Spread Spectrum (FHSS) rapidly changes the carrier frequency over a wide spectrum in a pseudorandom sequence, improving security and resistance to interference during data transmission.

About FDM
In FDM, each user is allocated a unique frequency band within the available spectrum. This allows multiple users to transmit simultaneously without interference, as their signals are separated by different carrier frequencies.
FDM divides the total available bandwidth into smaller, non-overlapping frequency bands, with each band dedicated to a separate signal. The spectrum is organized to ensure efficient use of bandwidth, with guard bands in between to prevent overlap and interference.
