In a Wireless Communication System, tower mounted transmission lines and cables are replaced frequently, perhaps every five to ten years, in some cases.

Replacing all the cables frequently is an expensive proposition.

A TDR cannot detect small performance changes at RF frequencies, so it is not possible to monitor performance degradation between maintenance intervals with these traditional methods.

Without FDR techniques, the “Fix after Failure” philosophy becomes the only alternative.

FDR is a transmission line fault isolation method which precisely identifies signal path degradation for coax and waveguide transmission lines.

Although the acronyms are similar, FDR technology is different from traditional Time Domain Reflectometry (TDR) techniques.
