This study discusses the multicast capacity of a large-scale random Ultra Wideband (UWB) wireless ad hoc network with power constraint. For different number of multicast destination, two different upper bounds of multicast capacity are given. When the number of multicast destination is , an upper bound of multicast capacity is when the number of multicast destination is , an upper bound of multicast capacity is . A strategy of MAC and routing which can achieve the lower bound of multicast capacity of power- constraint UWB wireless ad hoc networks is designed and the lower bound of multicast capacity is . These results extend the foregoing work on unicast capacity for UWB wireless ad hoc networks.
