Question: What is driving the need for dynamic allocation of radio resources between unicast and multicast services in 5G networks?
Option 1: Increased demand for voice over IP (VoIP) services
Option 2: Growing use of IoT applications that require low-latency communications
Option 3: Proliferation of video services, ad-hoc multicast/broadcast streams, software delivery over wireless, group communications and broadcast/multicast IoT applications
Option 4: Increased demand for online gaming services
Explanation: The proliferation of various multimedia and IoT applications is driving the need for dynamic allocation of radio resources between unicast and multicast services in 5G networks. This will enable efficient delivery of real-time and streaming content over wide geographic areas, as well as specific areas with limited base stations.
