Abstract: In this paper the concept of infrastructure-dependent wireless multicasting (IDWM) is presented. IDWM aims to enhance the reliability of multicasting by modifying the infrastructure without requiring any modifications to the receiver's transceiver chain or its network layer stack. This paper presents packet error rate (PER) results measured from a testbed equipped with 802.11n nodes, when multicasting video through (i) one AP equipped with one antenna (ii) one AP equipped with two antennas which are co-sited, and (iii) one AP with two antennas located 23.4m apart. Empirical results are presented highlighting the improvement achieved in the PER when two transmitting sources, in this case two antennas are used to share the burden of multicasting data packets by halving the coverage area.
