Item 7: Narrative Statement

Background:

         Science Applications International Corporation (“SAIC”) is the largest employee-
owned research and engineering company in the United States, with revenues
approaching $7Billion and more than 40,000 employees. SAIC is internationally
recognized as a leader in providing information technology services, system integration,
and e-solutions to commercial and governmental customers. In the wireless area, SAIC
has on-going programs to promote public safety interoperability, location monitoring and
reporting, secure wireless LANs and WANs, and first-responder support systems. SAIC
is working on contracts with the Office of Domestic Preparedness (ODP), state and local
first responders, and the Department of Defense. SAIC’s goal is, “linking people and
data anytime, anywhere.”

       Part of SAIC’s wireless program development for the public safety community is
to develop new equipment and systems for the newly-allocated 4.94 - 4.99 GHz band.1
This band has the potential to provide high-speed data and possibly voice to emergency
vehicles over wide areas through the deployment of numerous wireless access points to
provide contiguous coverage. Development of these wide-area systems is just beginning
and SAIC is leading the way in that effort. SAIC envisions development of secure,
robust networks that will provide first responders with vital information, in real time,
delivered to vehicles, personal data assistants (PDAs), or other portable wireless
terminals. This is critical for responding to new and evolving threats and scenarios.

        The purpose of the Experimental License being requested is to allow SAIC to 1)
demonstrate the viability of 802.11(g) and similar technology in the newly authorized
public safety band from 4.94 - 4.99 GHz at various locations within the United States,
and 2) conduct an experimental program to develop equipment with various modulation
techniques that fit within the basic 802.11(g) mask, primarily in three “test bed” areas.

Research Program:

        Although there are various wide-area solutions in place in other bands, the 4.9
GHz public safety band provides new and unique challenges. This band provides
opportunities to deploy wideband data equipment over large geographic areas to provide
essentially seamless high-speed data to emergency responders. Design of systems with
sufficient infrastructure to provide RF coverage to the area to be served is just the
beginning of the design issues. Each access point must be interconnected to sufficient
fixed infrastructure to provide hand-off from site-to-site while minimizing the number of
hops, as well as the ability to maintain the location of each mobile unit to allow
immediate peer-to-peer communications. The system must be able to provide

 The proposed program would be in support of equipment and infrastructure that would
operate under the provisions of the FCC Rules and Regulations, Part 90, Subpart Y.
Portions of these rules are currently under reconsideration by the FCC, including the
permissible emission mask.

                                            1


information from hundreds of data bases, including building blue prints, maps,
meteorological data, and law enforcement information (eg NCIC crime database
connectivity). Additionally, the system must be capable of relaying real-time video from
emergency response scenes, or high quality pictures for diagnostics and triage.

        The scope of the research program involving RF characteristics consists of
propagation studies, development of frequency reuse patterns, and techniques to
minimize interference between sites that are part of the same system and sites belonging
to other networks, hence optimizing spectrum usage. On the data side, the program will
look at data error rates in a mobile environment, data throughput limits, error correction
techniques, and maximum site loading. To conduct such a research program, SAIC may
deploy up to 150 fixed stations over each test area and operate a sufficient number
of mobile units to tax the limits of the system. Fixed stations will be installed in key
locations within each test area, including, on poles, on rooftops, or other fixed facilities,
such as, traffic lights and lamp posts. In these areas, SAIC also plans to experiment with
point-to-point and point-to- multipoint uses of the band using up to 26 dBi antennas, as
contemplated in Section 90.1215 of the rules. Research will be conducted primarily in
three locations: San Diego, California; San Jose, California; and New York City, New
York.

        In addition to the specific research program, SAIC needs the ability to
demonstrate its equipment at trade shows, at public safety facilities (working with the
public safety entities in the area to assure that no interference will be caused), and at
other locations as may be needed to prove the viability of the design to the public safety
community. Locations may include industrial, residential, and rural settings. Such
demonstrations may occur anywhere within the United States. SAIC plans not to operate
more than ten sites in any one demonstration area outside its licensed test bed regions.

       SAIC stands ready to provide the FCC with any and all details of its research and
demonstration operations that may be conducted under the Experimental License in
accordance with Section 5.73 of the FCC rules. Further, SAIC believes that the research
program fits squarely under one of more of the qualifications listed in Section 5.3 of the
FCC rules, thus qualifying for an Experimental License.

Equipment:

        At the present time, there is no commercially available equipment for the 4.9 GHz
band. To allow testing to begin as quickly as possible, SAIC plans to utilize chipsets for
the IEEE 802.11(g) technology. This technology will reasonably represent other
modulation technologies that may eventually be developed. In the alternative, the public
safety community has expressed a desire to be allowed to deploy the 802.11 structure
because of its availability and low cost, so 802.11(g) may become the de-facto standard
in the band. RF equipment will be either specifically designed by SAIC for operation in
the band or will be equipment designed for neighboring bands that is modified to work at
4.9 GHz. In either event, the equipment will be prototype and will not be certified under
the FCC’s equipment certification rules. SAIC is aware that Section 2.803 of the FCC



                                              2


rules prohibits offering such equipment for sale. In addition, all prototype equipment will
carry the label required by Section 2.803(c) of the rules, which is:

       “This device has not been authorized as required by the rules of the Federal
       Communications Commission. This device is not, and may not be, offered for
       sale or lease, or sold or leased, until authorization is obtained.

        SAIC further acknowledges that operation of this equipment may not cause
interference to other authorized services and must accept interference in accordance with
the requirements of Section 5.111 of the rules. SAIC plans to work closely with the
public safety community in each deployment area to assure that interference will not
become an issue.

Technical Details:

        SAIC plans to generally follow the technical requirements in Part 90, Subpart Y
of the FCC Rules and Regulations. The following is being requested:

       Power: Transmitter power output: 2 watts (33 dBm)
              Mobile Environment EIRP: 16 watts (42 dBm - assumes a 9 dBi antenna
              and no line loss - higher gain antennas may be used with a
              corresponding decrease in transmitter power to maintain 16 watts EIRP)
              Fixed point-to-point/multipoint Environment EIRP: 800 watts (59 dBm)
              In both the fixed and mobile cases, these power limits conform to Section
              90.1215.

       Channels: Operation between 4.94 GHz and 4.99 GHz in accordance with the
                 channels defined in Section 90.1213.

       Emissions: 22M0G7D or 22M0GXW. In no event will the occupied bandwidth
                  exceed 22.0 MHz.2

       Antennas: Antennas will be mounted not higher than 20 feet (6.1 meters) above
                 ground or not more than 20 feet above any man-made structure unless
                 mounted on a tower already in the ASR database or on a tower not
                 requiring registration. Note that for the point-to-point/multipoint
                 antennas, the application shows “0” for beamwidth, horizontal
                 orientation, and vertical orientation. In fact, the answer for each
                 should be “various,” but the electronic filing system did not permit
                 that.



2
 SAIC is requesting 22M0GXW to permit use of alternative modulation schemes without
the need to modify the license for each experimental modulation that may be used. Also,
the 802.11(g) emission mask slightly exceeds 20 MHz bandwidth at very low levels, thus
SAIC is requesting 22 MHz bandwidth to accommodate the existing chipsets.

                                            3

Sites 2, 4, and 6: 150 fixed and 3000 mobile, each area
Sites 3, 5, and 7: 100 fixed, each area

Conclusion:

        SAIC desires to conduct a research and equipment demonstration program
designed to maximize the potential of the 4.9 GHz public safety band. No equipment is
currently available for the band and much research needs to be conducted in both the RF
and data environments. SAIC has the experience and resources to make a meaningful
contribution to the state of the art in this band. The requested Experimental License will
allow SAIC to deploy and test a variety of 4.9 GHz systems that will ultimately benefit
the public safety community. All operations will be conducted on a non-interference
basis and operations will be terminated should interference occur. For the above reasons,
SAIC respectfully requests grant of the instant application.

       If the Commission has any questions, they can be directed to Dr. Daniel,
