Dear Mr. O’Dell, There was a unexpected surprise with our equipment during integration with the aircraft and a cable connector adapter needs to be purchased. As a result, we would like to reschedule the ground tear at YPG for Monday, June 17, at the same time. All else remains the same. I hope this rescheduling does not conflict with AT&T or your plans.

Importance: High Dear Mr. O’Dell, I wanted to check if you had an opportunity to consider my request to perform a 20-minute aviation ground test of airborne cellular system at the Yuma Proving Grounds transmitting on LTE Band 14 (758-768 MHz) and Band 4 (2135 – 2140 MHz) prior to June 17. I apologize for the urgency, but we are scheduled to perform the flight test on June 19 and safety-of-flight rules require a ground test of new radios prior to flight. Should you have any questions, or prefer to talk through the request, please call my cell at your earliest convenience (858-753-8433). Thank you, Carlos Carlos I. Rivera Sr. Program Manager

Hi Chet: Thank you for your prompt response and for the introduction to Mr. O’Dell. Dear Mr. O’Dell: It is a pleasure to make your acquaintance. My team is working with National Guard to deploy an aerial cellular network on their predator drones to support first responders and carry 911 calls hours after a disaster strikes. We briefed Mr. Sambar on the benefits to FirstNet and he is supportive. We have been working with Chet to test the system 100 miles offshore on June 19, but need to find a location to run a 20-minute required ground test on the aircraft first. May we perform this ground test from the Yuma Proving Grounds during one of your maintenance windows at 0’dark hundred?

I forgot one to ask for one very important item that precedes the flight test by several days: ground testing of the radios on the aircraft. For safety-of- flight purposes, the aircraft must first radiate the same radios on the ground at the same power level before they can radiate them in the air. The test takes 20 minutes. Chet: Can we perform this ground test from Montgomery Field during one of your maintenance windows at 0’dark hundred? Warren: If Chet cannot allow this ground test, would you please put us in contact with the Yuma Market Manager to see if we can perform the ground test at the Yuma Proving Ground (we have access to hangar facilities there and it is in the middle of nowhere). <image006.jpg> From: Rivera, Carlos I.

Thanks for your quick response, Chet. I will send you our detailed schedule in the next few days. Regarding Band 1, we have an STA from the FCC approving it, but it asks that we coordinate with the license holders. We chose Band 1 because that is the specific NodeB equipment that our supplier had available to lend us for the test. The specific 5 MHz WCDMA channel that we want to test actually overlaps with your Band 2 PCS Block D Downlink and your Band 4 AWS Block D Downlink. Being 100 miles offshore should mitigate interference. Listed below are some helpful tables: <image007.png> The specific 5 MHz channel that we want to use is: 3G WCDMA: TX: 2135 – 2140 MHz RX: 1945 – 1950 MHz The San Diego database shows AT&T owns both: <image008.jpg>

Please send uis a detailed schedule and I will let the performance manager know . I should have a contact person doing the test so if we see anything, we can instantly call as a stop switch. I think, we may need to coordinate this to LA market as well to see if they have any objections due to Catalina islands or Navy Base. As for the spectrum, ATT does not won BAND1 so we are OK.

Hi Chet, We would like to perform our “over the ocean - 100 miles out” manned flight cellular testing on June 19. What process would like for us to follow in terms of coordination (establishing the day’s lines of communications, the “Stop Button” in case any problems arise, etc.)? Also I would like to ask if on the same day that we test on LTE Band 14, could we also test 3G WCDMA voice on Band 1 (specifically TX: 2135 – 2140 MHz and RX: 1945 – 1950 MHz) out in the same spot over the ocean. I’d be happy to set up a conference call if you think it’s best for coordination. Kind regards, Carlos m. 858-753-8433 P.S. We met earlier this week with Chris Sambar to brief him on our airborne cellular network for disaster recovery (FirstNet support) and humanitarian assistance (route 911 calls to PSAP). We informed him that the National Guard is going to be putting this solution on their Air National Guard MQ-9 UAVs. Mr. Sambar saw value in this solution (especially since it helps FN at no cost to his budget J ) and asked for a three-way meeting between the Air National Guard, AT&T/FN, and GA-ASI for coordination purposes.

HI Team, Thanks for the info. I can only speak for San Diego . The other proposed location is in Arizona Market. But that area does seem to be more isolated than Imperial County. As for the third location, doing it over the ocean West of San Diego. , that would depend how far as

Propagation over water and LOS can hit the San Diego coastline of 70 miles with a lot of sites. Hope that helps.

Dear Chet, Warren, Michael, Mike, and Soontorn: Thank you for your participation in last week’s conference call regarding our request for airborne cellular network testing near the Anza Borrego desert; it was very informative. It’s a shame that we missed testing in that area prior to AT&T initiating Band 14 and AWS-3 service. Following the conference call, the GA-ASI team met to come up with next steps and these three suggestions were raised for aerial testing: Option 1: AT&T to recommend a location which hasn’t been placed in FirstNet service yet Based on your knowledge of AT&T’s LTE Band 14 deployment plans, is there another area that AT&T still has not placed these bands into service and could serve as a candidate area for our airborne testing for a day or two? It doesn’t have to be in San Diego County; it can be over any county or state so long as can avoid interference. Option 2: GA-ASI proposes a more remote location, further away from roads, population and AT&T towers (see Maps 2 below) We would like to propose an area east of Yuma, AZ and west of Phoenix, AZ (shown in Map 1 below ) which is significantly farther from AT&T towers than the Anza Borrego desert test area we discussed on Thursday (left red rectangle below). Whilst transmissions from our airborne eNodeB would not reach your AT&T cell sites below at noise levels (-118 dBm at ??? bandwidth), they would be considerably attenuated based on the distances involved (see Map 2). The airborne test would take place 50 miles from Arizona State Routes 95 and 85, and 30 miles from Interstates 8 and 10. Option 3: Propose testing offshore, west of San Diego Testing offshore could be a last option. Attached is the information that you requested during our conference call. Please let me know if you have any questions or concerns with this information. We look forward to receiving your feedback. MAP 1.
