To operate in the 2360-2390MHz Telemetry Band and
9210-9810MHz Band in Sioux Falls, South Dakota.

ATTN.: Microwave Branch

Sierra Nevada Corporation hereby requests Special Temporary Authority (STA) to operate
within the 2360-2390MHz and 9210-9810MHz telemetry bands pursuant to Section 21.25
of the Commission’s Rules. Sierra Nevada Corporation requests that the Commission grant
it temporary authority to operate on the frequency centered at 2380MHz with a 20MHz
bandwidth from September 10, 2018 through October 10, 2018 with intermittent usage.
Additionally, Sierra Nevada Corporation requests that the Commission grant it temporary
authority to operate on the frequency centered at 9510MHz with a 600MHz bandwidth from
September 01, 2018 through October 05, 2018. As explained below, Sierra Nevada
Corporation is filing an STA request to demonstrate high altitude MESH networking and
wide area surveillance for the United States Southern Command (USSOUTHCOM)
originating over Baltic, South Dakota and concluding in Central Illinois. Sierra Nevada
Corporation submits that there are extraordinary circumstances warranting a grant of the
STA request.

The United States Southern Command (USSOUTHCOM) has contracted Sierra Nevada
Corporation to conduct high altitude MESH networking and wide area surveillance tests
within a flight plan (attached below) over South Dakota. Due to the extreme frequency
congestion in the area, Sierra Nevada Corporation requests the use of these channels.

Sierra Nevada Corporation certifies that the operation of the requested channel for the
purposes specified herein will not cause interference to any established stations.

Grant of the instant request for STA for 2.3GHz and 9GHz Bands would serve the public
interest by enabling Sierra Nevada Corporation to conduct high altitude MESH networking
tests over South Dakota to provide a persistent surveillance system to locate and deter
narcotic trafficking and homeland security threats. Sierra Nevada Corporation 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:
