Abstract
Methods and arrangements are provided that allow for data communications between a plurality of devices over a reduced bandwidth communication medium, such as, for example, a twisted pair wire as used in many home environments for telephone access. The methods and arrangements advantageously reduce the necessary bandwidth required for a data communication by eliminating the need to transmit encoded data, such as Manchester encoded data between devices. Thus, for example, Ethernet configured data that is encoded and output by a network interface within a sending device/appliance is intercepted, decoded, transmitted over a reduced bandwidth communication medium, and then re-encoded and re-transmitted or otherwise supplied to the network interface within the receiving device/appliance. For Manchester encoded data signals associated, for example, with a 10 BASE-T Ethernet network, the encoded data signal has a data rate that is twice that of the decoded data signal. Therefore, using the methods and arrangements of the present invention, an intercepted 20 Mbps Manchester encoded data signal is decoded to a corresponding 10 Mbps data signal, modulated using an RF carrier, transmitted for…
