ABSTRACT:
Bandwidth is reduced when transmitting content to a cellular device. Requests for a content item are received from a first cellular device and a second cellular device. The content is divided into a first portion and a second portion. A first portion plan corresponding to the first cellular device and second portion plan corresponding to the second cellular device are determined. The first portion plan may include instructions for transmitting the first portion from the first cellular device to the second cellular device and reconstructing the content item. The second portion plan may include instructions for transmitting the second portion from the second cellular device to the first cellular device and reconstructing the content item. The first portion and the first portion plan are transmitted to the first cellular device. The second portion and the second portion plan are transmitted to the second cellular device.
