Give the following information of person who can best handle inquiries pertaining to this application:   Last Name: Nealy First Name: Randall Title: Lecturer Phone Number: 540-231-7280

Explanation

Please explain in the area below why an STA is necessary: The STA provides for tests to determine compatibility of LTE signals in the 3550 to 3650 MHz frequency band with transmissions from existing in-band radar systems. These tests will be conducted with cooperation from the Navy radar operators.

Purpose of Operation

Please explain the purpose of operation:

The purpose of the operation is to operate a small cell LTE radio system in the presence of in-band radar transmission in order to evaluate compatibility at short ranges. The LTE radio equipment will be set up at various distances from the radar and operated while the radar is transmitting. BLER, CQI and other data will be recorded to evaluate the impact of the radar on the operation of the LTE link. The main incumbent in this band, the U.S. Navy, is participating in these tests, through NAVAIR, Pax River, and the U.S. Naval Academy. We have examined the FCCs IBFS database and determined that the closest in-band incumbent FSS earth station is more than 100 km away, and therefore no interference from our low-power LTE signal is anticipated.

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.
