Question: What is a necessary consequence of the multi-drop broadcast link nature of the physical layer on the Iuant interface between a RAN Node and RET antennas or TMAs?
Option 1: Full duplex communication to handle simultaneous transmissions
Option 2: Half duplex communication with an appropriate timing and access control scheme
Option 3: Increased transmission power to override potential interference
Option 4: Encryption to secure messages from unintended recipients
Explanation: The multi-drop broadcast link means all devices receive every transmission, and simultaneous transmissions result in garbled messages. Half duplex communication (where devices take turns transmitting) is necessary to avoid this issue, and an appropriate timing and access control scheme ensures orderly transmission without conflicts.
