Mutlticast Streaming for WiFi

Multicast packets are delivered in each DTIM period so don't assume that you can get the quality same as videon on demand (VOD) which is categorized as unicast streaming. I first thaught that the quality of multicast streaming will be better than unicast streaming. But it is actually the other way round. Anyway, if you would like to reduce the number of IP packet and number of PHY acknowledgement frame, multicast is still a better choice. My test experiences always show that the same wifi chipsets between the AP and clients provide better results.
