SUBJ: Proposed Approval for Testing Persistent Systems Wave Relay Data Downlink System for
testing in the Fort Collins area.

Description:

Persistent Systems, LLC has developed a data downlink system for use with airborne and
ground terminal users. Several customers have requested testing of the Persistent Systems
Data Link for evaluation of this technology for mobile and airborne operations. Testing with
customers is scheduled for 2018, setup and training will begin as soon as a grant is approved
(please see requested dates below).

Frequency Requested: 2277.00 MHz

Duration of Program: 6 months (anticipate continued testing after initial testing)

Program Notes: 2277.00 MHz is the preferred frequency to provide a consistent benchmark
for testing and evaluation. The Wave Relay Data Link center frequency is available from
2200-2500 MHz in 5Mhz steps. Frequency change can be facilitated remotely should the
need to do so arise. Planned testing can take place during daytime and/ or night time
hours as needed. A seven (7) day week is planned for testing and evaluation.

Note: Map showing the area of operations on following page for program plans discussed
below.

Wave Relay Data Link will operate primarily in the 20MIRAD area shown in the map below
daily as needed for testing. A ground antenna will be located at 5042 Technology PKWY, Fort
Collins, CO (40.517153°N, -105.014967°W). The ground station antenna can use either
directional or omni directional antennas. It is intended to maintain a link with mobile ground
stations in the local area. The MIRAD for this request is 20mi (32km) to ensure coverage of
operations area and allow for limited range testing.

Testing will cover systems operation, real-time sensor/ telemetry data, and high definition full
motion video to and from individual data links. Throughout the testing period, frequency
changes and/ or complete shutdown of all radiating sources from the Wave Relay units can
be accomplished from the ground within 30 minutes of notification. Operation is for ground
test only at this time.

For stop buzzer please contact Trent Bowman @ (646) 627-8931 (primary POC), Mat Buhler
(646) 627-8174.
