TDD (Time Division Duplex)

2. FDD (Frequency Division Duplex):
• Used in telecommunications to allow for bidirectional
communication over separate frequency bands.
• In FDD systems, distinct frequency bands are allocated for
uplink (transmitting from user equipment to a base station) and
downlink (transmitting from the base station to user equipment)
communication.
• This allows for simultaneous transmission and reception in both
directions.

4. TDD (Time Division Duplex):
• Used in telecommunications to allow for bidirectional
communication over a single communication channel.
• In TDD systems, both upstream (transmitting from user
equipment to a base station) and downstream (transmitting from
the base station to user equipment) communication occur over
the same frequency band, but not simultaneously.
• TDD systems allocate different time slots for transmitting and
receiving data. This means that during a specific time interval,
the channel is used for either transmitting or receiving data.
