The transfer of real-time VoIP data over wireless and mobile networks is subject to packet losses that yield unacceptable quality. This work proposes that the quality can vary significantly depending on the packet coding method used. An adaptive piggyback packet coding that can provide the VoIP user acceptable quality over the wide range of packet loss conditions observed in wireless and mobile networks is found.
