SUBJ: Proposed Approval for Testing Persistent Systems Wave Relay Data Downlink System
for testing with the KRIV FOX network.

Description:

Persistent Systems, LLC has developed a data downlink system for use with airborne and
ground terminal users. FOX has requested testing of the Persistent Systems Data Downlink for
evaluation of this technology for mobile and airborne operations. Testing with FOX is
scheduled for JAN-June 2018, setup and training will begin as soon as a grant is approved
(please see requested dates below). To facilitate testing and evaluation, Persistent Systems
is requesting that AFTRCC approve the following test and evaluation plan.

Frequency Requested: 2377.00 MHz

Duration of Program: 180 days (JAN –JUL 2018)

Program Notes: 2377.00 MHz is the preferred frequency to provide a consistent benchmark
for testing and evaluation, however any frequency from 2360.00 to 2390.00 MHz can be
utilized. Frequency change can be facilitated from the ground should the need to do so
arise. Planned testing and demonstration 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 & Radio Specifications on following page for program plans discussed below.

Persistent Systems, LLC and KRIV FOX will operate primarily in the 50MIRAD area shown in the
map below daily as needed for testing. A ground antenna will be located at 4261 SW
Freeway Houston, Texas 77027 (29.728493°N, -95.446828°W). The ground station antenna is
omni directional and is intended to maintain a link to mobile transmit stations. The MIRAD for
this request is 50mi (80.5km) to allow for max range testing. Ground check use is the primary
intent, no aircraft operating at this time.

Testing will cover systems operation, real-time telemetry data, and high definition full motion
video from remote ground station(s). Throughout the program 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.

For stop buzzer please contact Jeffery Washington at (816) 559-1866.
