Applicant certification
Neither the applicant nor any other party to the application is subject to a denial of Federal benefits that includes FCC benefits pursuant to Section 5301 of the Anti-Drug Abuse Act of 1988, 21 U.S.C. Section 862, because of a conviction for possession or distribution of a controlled substance. The applicant hereby waives any claim to the use of any particular frequency or electromagnetic spectrum as against the regulatory power of the United States because of the prvious use of the same, whether by license or otherwise, and requests authorization in accordance with this application. (See Section 304 of the Communications Act of 1934, as amended.) The applicant acknowledges that all statements made in this application and attached exhibits are considered material representations, and that all the exhibits part hereof and are incorporated herein as if set out in full in this application; undersigned certifies that all statements in this application are true, complete and correct to the best of his/her knowledge and belief and are made in good faith. Applicant certifies that construction of the station would NOT be an action which is likely to have a significant environmental effect. See the Commission's Rules, 47 CFR1.1301-1.1319.

Special Temporary Authority application - Explanation
Please explain in the area below why an STA is necessary:
The MITRE Corporation seeks an FCC Special Temporary Authority License to transmit data within the High Frequency (HF) band between 6.4 MHz and 16 MHz from several locations in Alaska from 18 July – 08 August 2017. There are two primary locations from which the test will be executed: 1) Joint Base Elmendorf (JBER), Anchorage AK, and 2) Barrow, AK. The JBER primary location has three local sites, only one will be used at any given time/date. Each site will likely be used during the three-week test period, just not simultaneously. The Barrow primary site has four local sites, only one of which will be used at any given time/date as with the JBER locations. As with JBER, each of the local Barrow sites may be used, just not simultaneously. USNORTHCOM is conducting a test between these locations and have asked the MITRE team conducting advanced beyond line of sight (BLOS) High Frequency (HF) communications to be part of the test. As such, we will need transmit authority for those 22 days in those locations.

Special Temporary Authority application - Initial values - Purpose of Operation
Please explain the purpose of operation:
The goal is to communicate reliably at a rate of 1-4 bits/Hz/s. We will test several waveforms we have developed ranging from 10 to 400-kHz bandwidth to achieve ~ 256 kbps with forward error correction (FEC) coding. We may test waveforms out to 1 MHz bandwidth. Mitigation of signal fading and improved throughput will be accomplished using polarization diversity techniques and orthogonal coded waveform designs. The research program is planned to include a series of over-the-air (OTA) MIMO demonstrations, each testing new waveforms. We will attempt to test whether we can use both X and O modes to carry independent communications channels and then determine the carrying capability of each at different bandwidths. A stretch goal is to extend to wider bandwidth waveforms, up to 1 MHz. (Researchers’ note: we understand that this wideband waveform may run up against other users and possibly cause interference. We plan to transmit at as low a power as possible and on a not-to-interfere basis. Please see red-highlighted text in Table 1 attached Technical Amendment). We will also perform ionospheric sounding for channel characterization and waveform calibration.
