Abstract
In systems and methods of selecting access nodes for broadcast, signal strength metrics are received from a plurality of wireless devices, wherein the signal strength metrics are based on signals received by the plurality of wireless devices from a plurality of access nodes. A first signal strength criteria is determined for each of the wireless devices based on the received signal strength metrics, and wireless devices for which the first signal strength criteria meets a threshold are selected from among the plurality of wireless devices. A second signal strength criteria is determined for each of the plurality of access nodes. A minimum number of the access nodes is selected wherein the second signal strength criteria meets the threshold for each of the selected wireless devices, and a multicast transmission is transmitted from the selected access nodes to the selected wireless devices.
