What do you mean by FDMA? Explain?


Frequency Division Multiple Access or FDMA is a channel
access method used in multiple-access protocols as a
channelization protocol. FDMA gives users an individual
allocation of one or several frequency bands, or channels.
Multiple Access systems coordinate access between multiple
users. The users may also share access via different methods
such as TDMA, CDMA, or SDMA. These protocols are utilized
differently, at different levels of the theoretical OSI model.

Disadvantage: Crosstalk which causes interference on the
other frequency and may disrupt the transmission.
