Abstract: A method for transmitting data through a multi-media communication network includes converting transmission entities into data symbols at a first communication device, transmitting the data symbols from the first communication device to a second communication device through at least two different types of communication media using only lower PHY layers of the at least two different types of communication media, and converting the data symbols into transmission entities at the second communication device. A network implementing a universal data link includes a first communication device configured to convert transmission entities into data symbols, a second communication device configured to convert the data symbols into transmission entities, at least a first communication medium and a second communication medium communicatively coupled between the first communication device and the second communication device, and a first physical-layer translator configured to translate data symbols without converting the data symbols into transmission entities. In order to reduce processing time and end-to-end latency, the physical-layer translator only performs demodulation and modulation operations, optionally also equalization.
