Question: What is a key requirement for transmission performance enhancement in a 3GPP network when supporting high-quality video channels via broadcast?
Option 1: Supporting at least 5 low-quality video channels of 8Mbps each simultaneously via unicast.
Option 2: Ensuring a fixed allocation of 50% network capacity for broadcast and 50% for unicast.
Option 3: Designing mechanisms to support at least 10 high-quality video channels of 12Mbps each simultaneously via broadcast.
Option 4: Allowing only dynamic switching between unicast and broadcast on different carriers.
Explanation: This option correctly reflects a key transmission performance enhancement requirement for the 3GPP network, emphasizing support for multiple high-quality video channels over broadcast. This highlights the network's capability to handle demanding multimedia services efficiently, showcasing its robustness in managing simultaneous high-bandwidth transmissions.
