suBJECT: IBS INTERNET Study
Attached is the Work Statement for a study which I believe will
answer the question raised in your 6 January memo. If?you agree, I
will forward it to the Contracting Officer and work out a procurement
schedule.

STATII-~IVT OF WOKK
BACKGROUND
The Foreign Broadcast Information Service operates monitoring sites at
many locations worldwide. These sites are referred to as Bureaus and
monitor public media transmissions and publications for items of relevance
to the U.S. Government. Items so identified are analyzed and forwarded to
the Washington FBIS Headquarters .for distribution.
In support of-this mission, FBIS has leased a full transponder on an
IlVTELSAT located at 332.5 degrees east. The transponder is utilized as the
relay point for an emerging comnnmications system designated Il~'I'FRNET. The
function of INTFRNhT is to provide connectivity between the designated
Bureaus and to carry specific types of traffic ranging from high quality
audio to full motion television. At present the transponder carries one
24bII~iz television carrier, one 800KHz FM carrier and 13 - 75KHz FM carriers.
The satellite radiates, from the leased transponder, on a global beam;
thus, because of the satellite position over the Atlantic Ocean the FBIS
sites listed below are in the footprint:
Asuncion, Paraguay
Fort Clayton, Panama
Key West, Florida
Washington, D. C.
Caversham, England
Nicosia, Cyprus
Vienna, Austria
Tel Aviv, Israel
Amman, Jordan
l~abane, Swaziland
Abidjan, Ivory Coast
Washington, Ft. Clayton, and Caversham currently have IlVTIItNEr

earth terminal nodes. Each having a minimum G/T-of 34.7 db/degree K on
receive and a 54 db transmit gain.
Requirement: FBIS would like to conduct a feasibility study addressing
the issue .of placing limited International Business Service (IBS) terminals
at the Bureaus not now part of the INTIItNET System. "Limited" IBS service
is defined to be a data rate of 9600 bits der second (BPS) and the minimum
sized antenna consistent with a ten to the minus 6 bit error rate. It is
the intent to establish full duplex service between each node and
Washington. The contractor is to analyize the issue from a technical and
implementation point of view. Results of this effort will be presented to
FBIS in a detailed final report and an in-depth presentation.
TASKS TO BE COMPLETID
I. A comprehensive analysis of link performance (connectivity
between U.S.-Panama-U.K. may be excluded) including EIRP required, look
angle degradation, transponder intermod C/N impact, and projected
availability will be performed for each Bureau site.
II. A comprehensive analysis of anticipated antenna requirements
including antenna size trade-offs, expected side lobe suppression
requirements, and mounting methods is to be conducted.
III. Conduct an analysis of regulatory considerations in each of the
potential II~1'ERNiET sites. To be explicitly addressed, as a minimum,
are station licensing requirements/procedures, frequency clearing
requirements (RFI suppression), local zoning, if any, restrictions,
building construction permits, and expected processing time for all of
the above.

IV. Perform an on-site survey to verify the analysis performed in
Tasks I,_II, and III. The survey will, for each site, identify the.
exact location of actual equipment, establish the impact of this
determination on antenna size, RFI suppression,-and erection methods.
Sufficient frequency surveying must be completed to support the
licensing application. In addition, a complete set of the needed
application forms should be collected-from each potential site during
the visit.
