I. INTRODUCTION
This report presents the results of map studies together
with field verified location data for the proposed Overseas
Telecommunications, Inc.(OTI) microwave system connecting
Rosslyn, Virginia facilities with Independent Hill.
Virginia facilities. Feasible paths have been evaluated
using 7.5 minute topographic mapping of the Virginia area.
Section II of the report includes a summary of results for
the three (3) possible system routings. Conclusions are
presented in Section III. Supporting Documentation is
presented in Section IV.

II. SUMMARY OF RESULTS
This part of the report summarizes the results of map
studies and field verification of existing site/tower
locations. It has been divided into separate sections that
identify the paths that would be needed to achieve a
workable system based on the number of repeaters and
frequency band to be used.
At this stage of the project, no detailed frequency
interference analysis has been performed. Reference to
frequency bands of operation in the following paragraphs
refers to path profile presentations only, including
associated path clearances.
Direct Path_ Independent Hill _ Rosslyn
The field study confirms that a single path from Independent
Hill to Rosslyn cannot physically be achieved because of
taller buildings around the Rosslyn site. Therefore,
several other possibilities have been studied and listed
below.
One Intermediate Repeater Possibilities (Section 1~
--- ------------ ------------- -------- -
Two possible repeaters have been determined: WETA (#9) and
WAVA (#10 ). With reference to Exhibit 1 in Section IV,
Support Documentation, the longer paths, approximately 25
miles, between Independent Hill and the intermediate site
area if operated in the 11 GHz band could seriously degrade
overall system reliability because of excessive propagation
outages due to rain. If these paths were operable at 6 GHz,
then a frequency tradeoff study would be required to
determine compatibility with the proposed "C" band
Independent Hill earth station.
The two routes that appear feasibile from map studies are:

III CONCLUSIONS
The Rosslyn location is located such that a direct path
between Independent Hill is not possible.
- Taller buildings surrounding the customer locations in
Rosslyn limits the establishment of microwave paths between
150 degrees through 260, degrees referenced to true north.
- Three (3) different system routings are proposed in this
report. Each routing proposes the use of repeater location
between Rosslyn and Independent Hill.
- It may be necessary to utilize the 11GHz common carrier band
because of existing Earth Station uplinking facilities
between Rosslyn and Independent Hill which could adversely
effect 6GHz band operation. The 11GHz path lengths between
repeaters should be kept to a distance of 10 miles. Paths
lengths longer than 10 miles in the 11GHz band wi 11 be
subject to long outages due to rain which will affect the
overall system reliability.
- Based on the above two (2) or three (3) microwave repeaters
will be required if 11GHz is employed. One (1) repeater
will be required if 6GHz is employed.
