Explanation

The packet error rate is the key performance value that indicates an issue with Wi-Fi multicast video traffic. Multicast frames are not retransmitted on Wi-Fi, so any packet loss or high error rate will directly cause video artifacts, unreliability, or loss of stream integrity, even if coverage and throughput appear sufficient for other applications.
