Abstract
The present disclosure provides radio frequency (RF)-based OTN systems and methods. This includes a framework to carry services over RF-based links without using SONET/SDH or asynchronous radio. In an exemplary embodiment, the present disclosure utilizes an OTN framework over RF. Additionally, the present disclosure can also apply to other non-OTN frameworks such as an extended Ethernet frame with forward error correction (FEC) over RF-based links. The present disclosure combines existing OTN FEC with a radio FEC or with an over-the-air FEC to reduce the OTN FEC. Additionally, the present disclosure utilizes unused overhead to communicate RF data rates between radios.
