10.2.2 Multicast-to-Unicast Conversion
Scenario
When multicast-to-unicast conversion is not configured, packets are transmitted from the AP to STAs in multicast mode.
There is no acknowledgement and retransmission mechanism for multicast packets in wireless networks. As a result, severe
packet loss occurs, which affect experience of wireless multicast services in video on demand and other applications.
Wireless multicast packets between the AP and STAs can be configured to be transmitted in multicast-to-unicast conversion
mode in order to reduce the packet loss rate and enhance user experience.
