Power Efficient Broadcast Transmission Facilities Topic of New White Paper

--NAB FASTROAD-funded report includes proposal for industry-standard energy efficiency rating for transmitters--

WASHINGTON, D.C. -- NAB FASTROAD today released a White Paper on power-efficient broadcast facility transmission design for radio and television stations. With funding from the NAB FASTROAD technology advocacy program, this paper was researched and authored by the broadcast engineering consulting firm of Cavell, Mertz & Associates (CMA).

Consisting of two parts, this White Paper first presents a primer on power-efficient broadcast facility transmission design for stations that are considering the alteration or construction of new RF transmission facilities for over-the-air radio and DTV broadcasting. Topics include historical information on the evolution of transmitter efficiency, the impact of cooling system requirements on overall plant efficiency, and a brief discussion of "green" energy alternatives.

In the second part, a proposal for a "Transmitter Energy Efficiency Award" (TEEA) for broadcast transmitters is developed, reminiscent of the U.S. Government's "Energy Star" rating for home appliances. The TEEA proposal establishes a set of criteria and measurement methods that can be used to compare various transmitter products against one another, and would provide a tool for broadcasters to use in making "greener" decisions when purchasing transmission equipment.

A companion, web-based tool is also under development by CMA, designed to allow a broadcast station engineer or manager to conduct a "what if" study of various transmitter site topology decisions and their impact on facility long-term operational costs, as opposed to one-time capital costs. The web-based tool is expected to be launched by the end of the first quarter of 2011.

The full text of the White Paper, entitled "Power Efficient Broadcast Facility Transmission Design," and information on the NAB FASTROAD technology advocacy program are available at

NAB FASTROAD (Flexible Advanced Services for Television & Radio On All Devices) is the technology advocacy program of the National Association of Broadcasters. The overall mission of the FASTROAD program is to seek and facilitate development and commercialization of new technologies that can be exploited by broadcasters using radio and television broadcast spectrum.
