Subject: RE: Experimental License Application File No. 0379-EX-CN2018

Mr. Weinreich -

The purpose of our request for the experimental license with the FCC is to perform integration and verification
testing of our prototype design, make improvements and updates, and perform compliance testing for our
government customer. The product in question is a low power radar unit. The majority of testing will take place at
our Plano facility, however about 6 test flights will be required over the course of the 3 year license period.

These test flights would transmit and receive on the frequencies in question at very low power (3 watts) from an
altitude of no more than 2438 meters. The transmitter in our product emits very narrow pulses and changes
frequency multiple times per second. The duty cycle is on the order of 10% (transmit time vs receive time). During
a typical flight test, multiple flight passes are performed, with each flight pass consisting of operation on the order of
15 seconds, followed by data download, and repositioning of the aircraft. With the duty cycle and the frequency
hopping, I would estimate the product to be transmitting in your frequencies of interest only about (10 MHz/775
MHz [Frequency hopping])*(.1 [Duty Cycle])*15 seconds [time of a single flight pass] = ~20 msec. Each flight
pass requires starting and ending at specific points, with several minutes between flight passes. Typically only


about a dozen flight passes can be performed in an hour. On a good day of testing we may be able to fly for up to
six hours.

With the above information I believe during flight test our system could potentially interfere with your system
sporadically (no more than once every 5 minutes ) for a maximum duration of 20 msec no more than 72 times over
the span of 6 hours during a day of flight testing. With a 3W peak output power, your products sensitivity and the
distance from our system would determine the impact.

One of our product features is that it is difficult to detect in the RF spectrum, and to date we have not received any
reports of interference from any other licensees.

This experimental license request reflects an update of one that was previously active from December 11 2014
through December 01 2017 with the same low power and frequency considerations (prior experimental license
attached).

Please let me know if there is any additional technical data that I can provide.

Thank you

Dear Mr. Tolman,

Given the frequency ranges, power levels and modulation characteristics of your proposed emissions, Globalstar
feels that there is the potential for severe interference to our system operations.

In order to proceed, it would be beneficial for us to receive a detailed description of your proposed operations that


would be covered by this experimental license.

I look forward to your reply.

Subject: FCC Experimental License Coordination

Mr. Navarra -

L3 AS&T has submitted a request with the FCC for an experimental license to transmit in a frequency
range that may be of concern. As part of the FCC experimental license process, I am requesting
written consent of our proposed operations with any existing licensee that may be impacted by this
experimental license.

I have attached our FCC experimental license request. The items I believe to be of interest are:

Frequency of Operation/ Power / Location: Our test units may radiate up to 3 watts peak in the
frequency range of 1610-1620 MHz. Our operational test area is limited to a 100 Km radius of Plano
TX.
Testing is anticipated to occur ten to twenty times at our facility in Plano on the ground over the
next 3 years. Airborne testing is anticipated to occur about 6 times over the next 3 years within 100
Km radius of our facility in Plano TX.

In order to minimize interference, we are willing to coordinate test plans ahead of time and limit the
duration of testing in the frequencies of concern.

Thank you for your assistance in this matter.

Good morning Mr. Aliani –

Thank you for working with me to coordinate this experimental license.

In response to your questions -

Our original experimental license expired and this license is a replacement for it under a separate
government contract.
There is no change to the bandwidth of the TX carrier signal from the prior license (WH2XNP) – 150
MHZ is the bandwidth of our pulse mode, the mode that has the widest bandwidth.
Our current test plan calls for operation of one unit at a time for evaluation and verification.
We need to operate across all requested frequencies our device is capable of transmitting on to
verify device performance at each frequency and that the frequency hopping capability does not


impact performance.
We are willing to interrupt or stop testing on notification of interference - I am listed as the “stop
operations contact” in case of interference with any other system.

Please let me know if I additional information is needed!

Thank you for your prompt response!

Hello David,

Thanks for reaching out to us. I have some follow up questions.

•         What is the status of the Experimental License and testing with call sign WH2XNP?
•         What is the Tx carrier BW (of the new test program)?
•         How many test units that will be transmitted simultaneously during the testing?


•      Does L3 need to operate at specific frequencies?
•      Is L3 willing to interrupt their testing should interference to Ligado’s system becomes
unacceptable?

Regards,

Maqbool

Mr. Davenport / Mr. Aliani –

John Janka indicated you would be the best point of contact regarding our request for coordination
of our FCC experimental license.

L3 Advanced Systems and Technology has submitted a request with the FCC for a temporary
experimental license for a duration of 3 years. This license will be used to evaluate and test one of
our products in support of a governmental contract. The FCC requested we coordinate with
Lightsquared / Ligado Networks (Call sign E100051 and E080031) for potential interference in the
1626.5-1660.5 MHz portion of the band.

This experimental license we have applied for is similar to one we previously held, with call sign
WH2XNP.

Details of interest in our FCC experimental application:

Frequency of Operation/ Power / Location: Our test units may radiate up to 3 watts peak in the
frequency range of 1626.5-1660.5 MHz.
Our operational test area is limited to a 100 Km radius of our facility in Plano TX.
Testing is anticipated to occur ten to twenty times at our facility in Plano on the ground over the
next 3 years. Airborne testing is anticipated to occur about 6 times (each of 1 day duration) over the
next 3 years within 100 Km radius of our facility in Plano TX.

In order to minimize interference, we are willing to coordinate test plans ahead of time and limit the
duration of testing in the frequencies of concern.

Our complete FCC experimental license application is attached for your reference.

Thank you for your assistance.
