FDMA:

It stands for Frequency division multiple access.

• The entire allocated radio spectrum is divided into many slices of the frequency bands and each band or channel is allocated to user. The channel allocation can be done on a demand basis to the users to request service.
• When a call is processed, no other user can share the same channel.

• Users are assigned a pair of frequencies, one for forward channel and other for reverse channel.

Features:

• No synchronisation necessary
• Complexity of system is low
• All stations can operate continuously 24 hours without having to wait for their turn to come.
• Hard handover is done
