SUBJ: Proposed Approval for Testing Persistent Systems WR5100 Da ta Downlink System
during SOFIC Tampa 2017

Description:

Persistent Systems, LLC has developed a data downlink system for use with airborne and
ground terminal users. The US Special Operations Command (USSOCOM) has requested
testing of the Persistent Systems Data Downlink for limited evaluation of this technology for its
use to better enable its users in the future. The SOFIC event is scheduled for 11-19 MAY 2017.
To facilitate testing and evaluation, Persistent Systems is requesting that AFTRCC approve the
following test and evaluation plan. Persistent Systems personnel will conduct all testing and
use of RF equipment.

Frequency Requested: 2342MHz-2362MHz 5,10,20 MHz of bandwidth

Duration of Program: 9 days (11-19 MAY 2017)

Program Notes: 2342.00 MHz is the preferred frequency to provide a consistent benchmark
for testing and evaluation, however any frequency from 2342.00 MHz up to 2362 MHz using
5MHz steps can be utilized with minimal impact to testing and demonstration. Frequency
change can be facilitated from the ground should the need to do so arise. All testing will be
conducted during daylight hours. Only a request from USSOCOM would alter the planned
testing and demonstration testing hours. A five (7) day week (M-S) is planned for testing and
evaluation.

Note: Map & Radio Specifications on following page for following program plans.

The system will operate inside of the red circle shown in the map below on a daily as needed
for testing. A ground station will be located at the Convention Center in Tampa Florida – (N
27. 56’ 30, W 82. 27’24). The ground station antenna is omni directional and is intended to
maintain a link to the aircraft. The MIRAD for this request is 2.71 Nautical Miles (5km) to ensure
coverage of the aircraft operations area.

Testing will cover systems operation, real-time telemetry data, Radio over IP (RoIP) and high
definition full motion video. Throughout the test period, frequency changes and/ or complete
shutdown of all radiating sources from the WR5100 unit can be accomplished from the
ground within 30 minutes of notification.
