Abstract

Abstract The present invention relates to a system for communication over a network. The System comprises a network application, a protocol stack and a Medium Access Control layer. Further, the system is functionally and physically divided into a network application device and a network interface device. The network application device comprises the network application and the network interface device comprises the protocol stack and the MAC layer. A physical interface for bidirectional communication is arranged between the two devices. Also, the invention relates to the network application device and the network interface device separately and to a method for transmitting and receiving information via the network.
