4ipnet Wireless Access Point Optimization Part 4

Hello everyone! We'll continuing introducing how 4ipnet APs can enhance Wi-Fi performance. Today's topic is Multicast to Unicast Conversion.

In Wi-Fi networks, multicast packets are typically sent at slower rates to ensure that devices at the edge of an AP’s cell are able to receive the packets without error. This may be useful in environments where most clients are a certain distance (further away) from the AP. However, if the cell size is very small and most clients are densely packed around the AP, this would be an inefficient use of airtime. Why send at 11M when you can send at 300M?

MULTICAST TO UNICAST CONVERSION is a method that 4ipnet APs employ to convert multicast transmissions to unicast so that they can be sent at unicast rates. When clients are close to an AP, high transmission rates can be more easily sustained, and thus unicast is more efficient. On the other hand, attempting to use the same rate with clients far away from the AP will lead to a high number of retransmissions, which lowers efficiency. As a result, Multicast to Unicast Conversion is not a universally beneficial feature – it merely allows network administrators to optimize performance based on how clients are spatially distributed around APs.

Multicast to Unicast Conversion is ideal in environments where the majority of clients are densely packed around APs
