In re Application of

Silvus Technologies, Inc.
10990 Wilshire BLVD., Suite 1500
Los Angeles, California 90024

To operate at 1350-1390MHz, 2360-2390MHz and 5850-5870MHz Telemetry Bands in
Oceanside, California.

ATTN.: Microwave Branch

Silvus Technologies, Inc. hereby requests Special Temporary Authority (STA) to operate
within the 1350-1390MHz, 2360-2390MHz and 5850-5870MHz telemetry bands pursuant
to Section 21.25 of the Commission’s Rules. Silvus Technologies, Inc. requests that the
Commission grant it temporary authority to operate on the frequencies centered at
1370MHZ, 2385MHz and 5870MHz with a 5MHz bandwidth from May 04 through
September 04, 2015 with intermittent usage. As explained below, Silvus Technologies,
Inc is filing an STA request to test RF coverage with relation to wave propagation over
the ocean for the Defense Advanced Research Projects Agency (DARPA). Silvus
Technologies, Inc submits that there are extraordinary circumstances warranting a grant
of the STA request.

DARPA has contracted Silvus Technologies, Inc to test a wireless telemetry system. Due
to the extreme frequency congestion in the Southern California Area, coupled with the
added congestion from traditional Television and News coverage of area events, Silvus
Technologies, Inc. requests the use of these channels.

Silvus Technologies, Inc. certifies that the operation of the requested channels for the
purposes specified herein will not cause interference to any established stations.

Grant of the instant request for STA for the 1.3GHz, 2.3GHz and 5.8GHz bands would
serve the public interest by enabling Silvus Technologies, Inc to demonstrate the
reliability of the fixed link RF system for the laboratory. The proposed service would
enable testing of the bit stream by providing an RF fixed link across a large body of water
between Oceanside, CA and Scripps Pier that would not otherwise be available to the
laboratory. Silvus Technologies, Inc is in the process of obtaining the consent of the
relevant frequency coordinators for this project, including AFTRCC. AFTRCC has
indicated its intent to forward the results of the coordination to the Commission.

In accordance with Section 74.633 of the Commission’s Rules, the following is provided:
