For each of the plurality of wireless devices, a location may be determined. A geographic area may be classified as a first broadcast classification based on the channel quality indicators received from wireless devices that comprise a location proximate to the geographic area. A transmission scheme may be determined for a broadcast transmission to wireless devices proximate to the geographic area based on the first broadcast classification, where the transmission scheme may comprise a least a modulation and coding scheme. One or more access nodes may then be instructed to broadcast using the determined transmission scheme for the geographic area.

Abstract: Systems and methods for sending data packets to a wireless device are provided. An access node can determine a number of wireless devices in communication with the access node that meets a signal quality criteria. The access node can determine when the number of wireless devices that meets the signal quality criteria exceeds a threshold. The access node can receive from a content node first multimedia broadcast service (MBMS) data. The access node can encode the first MBMS data into second MBMS data when the number of wireless devices that meets the signal quality criteria exceeds the threshold. The encoding can be based on the number of wireless devices in communication with the access node that meets the signal quality criteria, a load at the content node, a load at the access node, and a bit error rate of each wireless device in communication with the access node.
