This paper presents experimental studies on the use of IEEE 802.11b wireless Ad Hoc networks for Multicast. The experiments show that the maximal throughput achievable in such networks is 1.76 Mbps for an 802.11 Data Rate of 2 Mbps. This paper studies the behavior of VoIP traffic in such networks in multi-hop scenarios with and without hidden stations. The maximal number of hops for VoIP multicast traffic over 802.11 is four as critical loss ratios are approached for more hops. While loss turns out to be problematic, round trip time and delay characteristics of the VoIP streams remain acceptable in all scenarios.
