A source proxy for transmitting one or more TCP packets sent from a source device to a destination device over a wireless link is provided. Each TCP packet comprises a TCP data section and a TCP packet header. The source proxy is located on the wireless link and is configured to: receive the one or more TCP packets; determine a simple compression mode packet from the one or more TCP packets by removing the TCP packet header comprised in each TCP packet, the simple compression mode packet comprising the TCP data sections comprised in the one or more TCP packets and a header that comprises a connection identifier, and send the simple compression mode packet to a destination proxy located on the wireless link, the destination proxy being configured to: receive the simple compression mode packet and acknowledge reception to the source proxy; determine one or more reconstructed TCP packets by extracting the data sections of each TCP packet from the simple compression mode packet, and send the one or more reconstructed TCP packets to the destination device.
