ABSTRACT:
This invention provides a method and apparatus for providing easily adaptable and select transmission and reception rates between a number of clients and a server. With this invention a broadband signal is transmitted/received from the server to the clients, who individually may need to receive/transmit only a small portion of the composite signal. More specifically, this invention uses discrete multiple tone coding to provide the easily adaptable and selected transmission rates to the clients.
