Managing the High Definition (HD) Transition Bandwidth Requirements for ENG: Microwave Links from the Field

The migration from standard definition (SDTV) to high definition (HDTV) program content in news, sports and special events coverage has forced broadcast news and field production managers to find transmission technology that can support higher bit rates for HD-ENG transport streams, with the same signal margins, in the new 12 MHz channel plan of the 2 GHz BAS or the existing 7 GHz band. — This paper will examine terrestrial microwave radio transmission techniques that allow contribution bit rates in excess of 80 Mbps in field production applications. It will describe the tradeoffs in radio performance associated with specific applications in regard to bit rate versus bandwidth versus C/N threshold and how they relate to maximum microwave path distances.
