Explanation

Please explain in the area below why an STA is necessary: Requesting a STA to allow temporary evaluation of a 77GHz radar kit from Texas Instruments (IWR1642BOOST) for a potential train detection application at railroad crossings. Current technology used today for train detection at railroad crossings uses either track circuits or axle counters. Both solutions require connection of equipment to the rails, which are subject to vandalism at ground level and/or damage by track maintenance equipment. Both solutions are also susceptible to reliability issues caused by environmental conditions (eg rain, snow, magnetic fields, etc). US railroads are looking for more modern technologies to replace these solutions with something that does not require connection to the rails and is immune to vandalism, damage and reliability issues caused by environmental conditions. The 77GHz radar technology proposed for evaluation appears to nominally meet all of the technical requirements necessary for train detection at railroad crossings. The STA is requested to evaluate further its capability, particularly the ability to provide immunity against environmental conditions.

Purpose of Operation

Please explain the purpose of operation:

Evaluation of a 77GHz radar kit for a potential train detection application at railroad crossings. The temporary product evaluation will be conducted outdoors at a test facility on Alstom's campus in Grain Valley MO (https://goo.gl/maps/eAeMFeYhqvt ). Two radar units will be mounted to a fixed pole at an approximate height of 10 feet above ground and pointed downwards to observe the distance estimated by the radar transceiver to background objects (eg rails, ties, ground, etc). These estimated distances will be observed to study the variation over a time not to exceed 6 months with the purpose of studying the impacts of different environmental conditions (eg snow, rain, fog, temperature, etc) on the data. The goal is to understand the reliability of this technology to operate in an outdoor environment similar to that at a railroad crossing.

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.
