FDMA
FDMA
separates the spectrum into distinct voice channels by splitting it into
uniform
chunks of bandwidth.
To better understand FDMA, think of radio stations: Each station sends its
signal at a different frequency within the available band. FDMA is used
mainly for
analog transmission.
While it is certainly capable of carrying digital information, FDMA is not
considered to be an efficient method for digital transmission.

In FDMA, each phone uses a different
frequency.
