What are the disadvantages of full duplex?

Full duplex communication allows simultaneous data transmission in both directions, which can lead to increased complexity in network design and management. It often requires more bandwidth than half duplex systems, as both channels need to be active at the same time. Additionally, full duplex systems may be more expensive to implement due to the need for advanced hardware and technology. Finally, troubleshooting can be more challenging, as simultaneous data flow can obscure issues.
