Why STA Is Necessary:

Caterpillar hereby requests special temporary authority for six months to conduct outdoor
electromagnetic compatibility (EMC) immunity testing on prototype models of new, large earth-
moving machinery on three frequencies: 275 MHz, 325 MHz and 375 MHz at its Peoria Proving
Grounds and Tucson Proving Grounds sites.

Caterpillar is required to conduct EMC testing on its prototype equipments across a large number
of frequencies to ensure both product safety and compliance under different international
regulatory schemes, including those of the European Union. Outdoor EMC testing supplements
EMC immunity testing that is performed in an absorber-lined shielded enclosure. Because of the
size of Caterpillar’s heavy machinery, testing of these prototypes in a shielded enclosure is
practically impossible.

An earlier Caterpillar experimental application to conduct outdoor EMC testing on a large number
of frequencies was granted effective December 7, 2007. See FCC File No. 0003-EX-PL-2007.
However, despite a request in its application, Caterpillar’s experimental authorization did not
include authority to conduct EMC testing on any frequency in the 275-375 MHz band.

Unfortunately, Caterpillar must conduct some EMC testing in the 275-375 MHz band to comply
with international safety regulations. Unless it can certify compliance with the EMC compatibility
requirements in these international safety regulations, Caterpillar will not be permitted to export
any new products into the countries that rely on these regulations.

At the present time, Caterpillar has at least three prototype machines ready for EMC testing. This
testing is conducted during the product development stage to ensure that no machine goes to
production without satisfying the necessary safety regulations. To maintain the tight product
development schedules and continue to offer innovative products in the intensely competitive
international marketplace, Caterpillar must have some EMC testing authority on the three
requested channels.

For all of these reasons, Caterpillar requests experimental authority so it can commence EMC
testing on 275 MHz, 325 MHz and 375 MHz as soon as possible. Given the importance of
innovation to success in the marketplace, Caterpillar must have authority to bring new equipment
to market. Caterpillar submits that the requested STA is in the public interest and should be
granted.


Purpose of Operation:

Caterpillar is required to conduct EMC testing on its prototype equipments across a large number
of frequencies to ensure both product safety and compliance under different international
regulatory schemes, including those of the European Union. Outdoor EMC testing supplements
EMC immunity testing that is performed in an absorber-lined shielded enclosure. Because of the
size of Caterpillar’s heavy machinery, testing of these prototypes in a shielded enclosure is
practically impossible.

An earlier Caterpillar experimental application to conduct outdoor EMC testing on a large number
of frequencies was granted effective December 7, 2007. See FCC File No. 0003-EX-PL-2007.
However, despite a request in its application, Caterpillar’s experimental authorization did not
include authority to conduct EMC testing on any frequency in the 275-375 MHz band.

Unfortunately, Caterpillar must conduct some EMC testing in the 275-375 MHz band to comply
with international safety regulations. Unless it can certify compliance with the EMC compatibility
requirements in these international safety regulations, Caterpillar will not be permitted to export
any new products into the countries that rely on these regulations.


A pending experimental application (FCC File No. 0077-EX-PL-2008) represents Caterpillar’s
reasonable, good faith attempt to propose some tests in the 275-375 MHz band that will be
acceptable to the Department of Defense. In this application, Caterpillar reduced the frequencies
requested for testing to three: 275 MHz, 325 MHz and 375 MHz. It also modified its EMC testing
procedures so that the testing on these frequencies will be from a single, fixed location.

The ERP of Caterpillar’s proposed EMC testing on these frequencies is 500 watts with emission
designators 2K00A3E and 0H00N0N from an antenna less than 2 meters off the ground.
Caterpillar notes that the Commission has previously approved, presumably with the DOD's
concurrence, similar EMC testing proposals on and around these frequencies. See, e.g., FCC
File No. 0025-EX-RR-2002, Experimental Radio Station Construction Permit and License, Wyle
Laboratories, Inc. (granted effective Feb. 1, 2002) (allowing testing on 300 MHz and 350 MHz at
2,000 watts ERP with emission designators 100HA1A, 30K0P0N, and N0N).

If EMC testing on 275, 325 and 375 MHz cannot be authorized, Caterpillar request authority to
conduct its proposed EMC testing on any other channels between 275-375 MHz where testing
can be authorized. Caterpillar needs authority to test on channels in this band at increments of
no more than 50 MHz. Similarly, if Caterpillar’s proposed EMC testing at 500 watts cannot be
authorized, Caterpillar requests authority to conduct these tests at the highest power level that
can be authorized.

As noted in Caterpillar’s earlier application, EMC immunity testing involves placing a transmitting
antenna on or near the equipment under test and generating an RF signal with an RF signal
generator and amplifier. The RF signal is directed to critical electronic components on
Caterpillar’s large earth-moving equipment that could potentially be affected if operated in a high
electromagnetic field environment.

Any potential interference will be mitigated by the use of fixed antennas mounted close (2 meters
or less) to the ground and close (3 to 5 meters) to the equipment under test, which will greatly
limit the range of the transmitted signal. In addition, Caterpillar typically conducts outdoor EMC
testing on prototype equipment approximately 10 times per year and the dwell time on any single
frequency during one of these tests is less than 10 seconds.

In addition, Caterpillar personnel will be present for all aspects of the investigation, testing will be
coordinated with various public safety and government agencies in the area, and standards of
good engineering practice will be followed, with applicable FCC rules available as a reference.

For all of these reasons, Caterpillar requests experimental authority so it can schedule and
conduct EMC testing on 275 MHz, 325 MHz and 375 MHz. Given the importance of Caterpillar’s
prototype machines to maintaining and enhancing its global competitive position, Caterpillar
submits that the requested STA is in the public interest and should be granted.
