Bandwidth determined by data rate and "chipping rate" required to achieve SCADA rain fade
margins for a given antenna size.

Antennas ranging from 18" x 18" (LDR Terminal) to 30" in diameter (HDR Terminal) will
be tested. Comparisons will be made between flat array and dish antennas at the higher
aperture sizes.

The goal would be to minimize bandwidth requirements subject to data rate and reliability
levels for different applications.


antenna, are more reliable technologies that keep certain facilities operational during those
emergencies when ongoing service and rapid restoration are most important.

B.     System Description

        Electric utilities with large operating territories, like SCE, must establish Supervisory
Control and Data Acquisition ("SCADA") communications with a large number of remotely—
located operational sites. In addition to more traditional facilities, SCE uses remotely—located
windmill and other diverse power generation methods. These diverse operations, and the
additional complications introduced by the deregulation of key elements of the power system,
demand that SCE have an enhanced ability to control its electrical power system. Because of its
diverse facilities and remote locations, in operating a SCADA system, SCE must be able to
install SCADA terminals on utility poles, power grid towers, etc., to monitor and control circuit
breakers, switches and other equipment. The remote terminal must be a small, lightweight,
single unit that can connect directly to electrical equipment, but still can withstand rugged
outdoor environments. It must also be easy to install.

         With this in mind, SCE has developed a satellite—based communications system to fulfill
its SCADA requirements. The design is based on a new technology and has been awarded
United States patents, with foreign patents pending. The ability of this small antenna technology
to comply with the performance criteria of § 25.209 is paramount. SCE is working to achieve
improved antenna performance characteristics with its small flat array design. The antenna that
is the subject of this experimental authorization request represents next generation technology
that SCE hopes will improve its SCADA network operations and reduce operating costs, while
still achieving the non—interference performance criteria required by the Commission.

C.     Need for Testing Next Generation Flat Array Antenna

         SCE wishes to test new antenna designs under this experimental license in conjunction
with its existing Ku—band satellite network. The antennas will operate with these technical
characteristics:

       Emission designator:           IMO0G7D
       Maximum power output:          10 Watts
       Maximum EIRP     ;;            34 dBW
       EIRP density:%P CM             —20.2 dBW.4 kHz

       Through testing, SCE will be able to demonstrate that use of the next generation flat array
antennas in its network will not create any interference concerns and will comply with the
antenna performance standards set forth in § 25.209.

D.     System Architecture Designed to Insure Compliance with Interference Criteria

       In addition to the design performance criteria that will be incorporated into the next
generation flat array antennas, to ensure ultimate compliance with the FCC‘s interference

                                               _2 .


standards, the following overall system architectural characteristics have been implemented in
SCE‘s network to prevent interference concerns even during this experimental testing phase:

       *       100% deterministic (synchronized) operation of the network
       *       All transmissions are under direct control of the Regional Control Center
               terminal
       *       The Regional Control Center terminal continuously monitors end—to—end radio
               frequency power calibration of the LDR or HDR terminals and makes automatic
               adjustment as necessary
       *       The Regional Control Center terminal implements rain fade compensation in such
               a manner that eliminates the possibility of increased interference despite
               variations in the spatial distribution of the rain fade.

E.     Testing Plan

        *      The Regional Control Center terminal uses the RF head and antenna authorized
under the current FCC earth station licenses, call signs E940064 and E940065. Under SCE‘s
operating Ultra—Net system, four (4) Regional Control Center terminals and two remote—DAC
terminals have been installed and fully tested. One hundred and ninety remote satellite terminals
have been installed and fully tested to monitor and control remote substations. SCE now seeks
authority to add up to 200 next generation flat array or 30" reflector antennas to the network to
complete full testing of this equipment. During the period of the experimental authorization, the
next generation flat array antennas will be fully tested so data may be developed to present to the
Commission to obtain regular operational authority for the new design.

       &       Data Rate


                The next generation remote terminal will be used for information data rates of
[10 kbps] or less. Typically, in a SCADA system, multiple remote terminals will communicate
with a single Regional Control Center terminal.

       &       FAA Compliance

              SCE will install its next generation remote terminals on structures that already
meet Federal Aviation Administration requirements. Moreover, remote terminals are always
mounted below the top (the authorized height) of the structure in question.

F.     Point—of—Contact

        SCE will maintain its testing records of location and frequency use with the following
point of contact:

G.       Radiation Frequency Hazard Compliance

         30x 30"° Antenna

       In accordance with FCC rules, SCE performed a radiation hazard study for its 30x 30"
remote terminal. The FCC—OET Bulletin No. 65, "Evaluating Compliance with FCC Specified
Guidelines For Human Exposure to Radio Frequency Radiation" was used as a reference guide.
The formulas were adjusted for the antenna‘s square aperture and absence of a feedhorn. The
parameters set forth in Table 1 (Radiation Hazard Study Parameters) were used in the study:

        The remote terminals are located in areas not accessible to the public, such as on utility
poles, high voltage towers and fenced substations. The results of the SCE‘s study are
summarized in Table 2:

        Based on the above analysis, it is concluded that harmful levels of radiation will not exist
in regions normally occupied by the public or by the earth stations operating personnel. The
transmitter will be turned off during antenna maintenance so that the 5.0 mW/em*2 standard will
be observed even in those areas with close proximity to the reflector that exceed acceptable
hazard levels under normal operations.


       30"° Diameter Antenna

       In accordance with FCC rules, SCE performed a radiation hazard study for its 30"
diameter terminal. The FCC—OET Bulletin No. 65, "Evaluating Compliance With FCC Specified
Guidelines For Human Exposure to Radio Frequency Radiation" was used as a reference guide.
The parameters set forth in Table 1 (Radiation Hazard Study Parameters) were used in the study:

Conclusion: Based on the above analysis, SCE has concluded that harmful levels of radiation
will not exist in regions normally occupied by the public or by the earth stations operating
personnel. The transmitter will be turned off during antenna maintenance so that the 5.0
mW/em*2 standard will be observed even in those areas with close proximity to the reflector that
exceed acceptable hazard levels under normal operations.

Antenna Pattern Data


Figure E—1 shows the antenna pattern for SCE‘s experimental license using a 30" reflector
antenna. In experimenting with various antennas roughly of this aperture or smaller, SCE will
adhere to the EIRP power density constraints using the Ultra—Net*Y integrated power control
techniques of SCE‘s Ultra—Net*Y permanent operating license for the 10" x 16" dish network.

                                Experimental License Application

        SCE seeks an experimental license to test a flat array antenna with the characteristics
identified in this request. SCE has received domestic fixed satellite service licenses under the
call signs E940064 and E940065 for its VSAT system operating in the Ku—band using 10" x 16" /@/FZL
conventional dish reflector antennas. In addition, SCE has applied for permanent authorization   2
for advanced flat array antennas, measuring 18" x 18" and 30" in diameter both with a superior
beam pattern and pointing accuracy.                                                               4

A.     Applicant Background

       SCE is the second largest utility in the nation. Its service area stretches from Los
Angeles, California, east to the Arizona border, and north to the Mono Lake region. Within this
50,000 square mile expanse, SCE serves over four million residences, schools, hospitals,
businesses and government facilities. In total, SCE provides electricity to approximately 9
million people, or almost one in every thirty persons in the United States.

       To ensure that its essential service is provided safely and efficiently to all of its
customers, SCE maintains a large, complex internal telecommunications network. SCE
extensively employs private wire and fiber lines, the public switched telephone network, land
mobile radio, microwave radio and satellite earth station facilities in its internal
telecommunications network. Together these services enable SCE to meet its enormous public
service obligations. A reliable communications network is indispensable to customer service and
for the maintenance, repair and emergency preparedness activities associated with SCE‘s
distribution system, its generating plants and its major transmission facilities.

         SCE‘s territory is known for severe natural disasters and extreme weather conditions,
including El Nifio, forest fires, mud—slides and earthquakes such as the one centered in
Northridge on January 17, 1994. Consequently, reliable communications are critical to SCE‘s
ability to quickly detect service outages, to promptly restore service and to protect the public
from downed "live" wires and other safety hazards that can occur during emergencies. Landline
communications facilities, such as telephone lines and fiber optic cable are sometimes ruptured
during earthquakes and other emergencies. For this reason, radio—based communication              |
