100+ VoIP Calls on 802.11b: The Power of Combining Voice Frame Aggregation and Uplink-Downlink Bandwidth Control in Wireless LANs

Sangki Yun, Hyogon Kim, Heejo Lee, and Inhye Kang

Very interesting... so many things to summarize! Deals with uplink/downlink unfairness aspects, packet aggregation at the MAC level, E-model.

The key idea is that the channel access is the main overhead in VoIPoWLAN. Thus aggregating packets belonging to the same call at the mac level drastycally boosts the performance.
