ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: In this document, the Federal Communications Commission (Commission) amends its rules to permit vehicular radars and certain non-vehicular fixed and mobile radars used at airports to operate in the entire 76-81 GHz band on an interference-protected basis. Access to the entire 76-81 GHz band is intended to provide sufficient spectrum bandwidth to enable the deployment of wideband high-precision short- range vehicular radar (SRR) applications, such as blind spot detectors, that can enhance the safety of drivers and other road users, while continuing to allow the deployment of proven long-range vehicular radar (LRR) applications, such as adaptive cruise control. The amended rules also permit the deployment in airport air operations areas of fixed and mobile radars that detect foreign object debris (FOD) on runways, which could harm aircraft on take-off and landing, and aircraft-mounted radars that can help aircraft avoid colliding with equipment, buildings, and other aircraft while moving on airport grounds. In addition, the amended rules allow for the continued shared use of the 76-81 GHz band by other incumbent users, including amateur radio operators and the scientific research community. DATES: Effective date: Effective October 20, 2017, except for Sec. 15.37(l), which is effective September 20, 2018. Applicability date: Section 15.37(o) was applicable beginning July 13, 2017.

Synopsis I. Introduction 1. On February 3, 2015, the Commission adopted a Notice of Proposed Rulemaking (NPRM) in this proceeding. 80 FR 12120, March 6, 2015. In the Report and Order, the Commission amended the United States Table of Frequency Allocations (U.S. Table) in Sec. 2.106 and several related service rules to establish a comprehensive and consistent set of rules and policies for radar operations in the 76-81 GHz band. The following are the major actions that the Commission took to support the deployment in the 76-81 GHz band of advanced vehicular radar applications and certain non-vehicular fixed and mobile radar applications for use at airports:Allocated the 77.5-78 GHz band to the Radiolocation Service on a primary basis in the U.S. Table to provide a contiguous five gigahertz band at 76-81 GHz for radar operations. Allowed vehicular radars and certain non-vehicular fixed and mobile radars used at airports to operate in the entire 76-81 GHz band. Consolidated radar operations in the 76-81 GHz band under part 95 of the Commission's rules to be licensed-by-rule and protected from interference with the same technical parameters as currently specified for 76-77 GHz radars in part 15 of the rules. Restricted fixed radar operations to airport air operations areas to prevent such radars signals from illuminating public roadways and causing harmful interference to vehicular radar operations. Reduced the maximum equivalent isotropically radiated power (EIRP) of amateur and amateur satellite operations in the 76-81 GHz band to match that of radar operations in the 76-81 GHz band to reduce the potential for these amateur operations to cause harmful interference to radar operations in the band. II. Discussion 2. In the Report and Order, the Commission amended parts 1, 2, 15, 90, 95, and 97 of its rules to facilitate the deployment in the 76-81 GHz band of advanced vehicular radar applications and certain fixed and mobile radars in airport air operations areas. These actions are described in greater detail below. A. Allocation Changes to the 77.5-78 GHz Band 3. As proposed in the NPRM, the Commission allocated the 77.5-78 GHz band to the Radiolocation Service (RLS) on a primary basis in the U.S. Table. This action made the entire 76-81 GHz band available for licensed radar applications on a primary basis nationwide and brought the U.S. Table into agreement with the International Table of Frequency Allocations. In response to commenters' concerns about the potential for interference from amateur operations to vehicular radar operations in the 76-81 GHz band, the Commission changed the Amateur Service and Amateur Satellite Service allocations in the 77.5-78 GHz band of the U.S. Table from primary to secondary status to match the secondary Amateur Service and Amateur Satellite Service allocations in the remainder of the 76-81 GHz band. As secondary users in the 76-81 GHz band, amateurs will have an obligation to operate in a manner that minimizes the potential for harmful interference to licensed radar applications that will operate under the primary RLS allocation throughout the entire 76-81 GHz band and Radio Astronomy Service (RAS) stations in the 76-81 GHz band, and cannot claim protection from harmful interference from any primary service. If amateur radio operators cause any harmful interference, they will be required to provide an immediate remedy, up to and including terminating their operations. As an added protection against potential interference from amateur operations to vehicular radar operations in the 76-81 GHz band, the Commission amended the part 97 Amateur Radio Service rules to specify a maximum EIRP of 55 dBm (316 Watts) that Amateur Service and Amateur Satellite Service stations in the 76-81 GHz band may transmit, the same as the allowable vehicular radar peak EIRP limit. 4. Although the Commission determined that the addition of the primary RLS allocation in the 77.5-78 GHz band did not raise any new interference considerations for RAS operations in the 76-81 GHz band, because there is no distinction between RAS use of the 77.5-78 GHz band and the remainder of the 76-81 GHz band it upgraded the secondary RAS allocation [[Page 43866]] in the 77.5-78 GHz band to primary status to match the RAS allocations in the 76-77.5 GHz/78-81 GHz bands. By making the RLS and RAS co- primary throughout the 76-81 GHz band, the Commission provided regulatory consistency between the two services and eliminated the potential problem, in the event of harmful interference to the RAS due to vehicular radar operations, of determining protection rights in favor of addressing and mitigating the interference concern. However, since the Commission determined that addition of the primary RLS allocation in the 77.5-78 GHz band did not raise any new interference considerations that would justify upgrading the secondary Space Research Service (space-to-Earth) (SRS (space-to-Earth)) allocation in the 77.5-78 GHz band to primary status, the Commission maintained this service's current secondary status, consistent with the SRS (space-to- Earth) allocations in the remainder of the 76-81 GHz band. Given the size and scope of the automotive fleet in the United States as compared to the two RAS facilities that operate in the 76-81 GHz band, the Commission declined to adopt commenters proposals for an automatic or manual on/off switch and coordination zones in the vicinity of RAS observatories for vehicular radars that operate in the 76-81 GHz band. B. Consolidating Vehicular Radar Operations Into the 76-81 GHz Band 5. As part of the Commission's efforts to consolidate future vehicular radar operations into the 76-81 GHz band, the NPRM noted that there is little or no use of vehicular radars in the 16.2-17.7 GHz and 46.7-46.9 GHz bands, and sought comment on modifying the Commission's part 15 rules to no longer approve vehicular radar devices for operation in these bands. Since no commenters opposed this suggestion, the Commission deleted the references to vehicular radar operations in the 16.2-17.7 GHz and 46.7-46.9 GHz bands from the Commission's part 15 rules and ceased accepting applications for equipment certification of such devices effective upon the adoption of the Report and Order. It prohibited the continued manufacture, importation, marketing, sale, and installation for use in the United States of such equipment in the 16.2-17.7 GHz band under the sole existing equipment authorization, FCC ID No. L2C0004TR. However, it grandfathered, for the life of the equipment, any vehicular radars that are already installed or in use under this authorization, thus allowing such systems to continue operating for the life of the vehicle or until the supply of existing equipment necessary for maintenance is exhausted. 6. As proposed in the NPRM, the Commission also phased out unlicensed wideband radars authorized under Sec. 15.252 to operate in the 23.12-29 GHz and ultra-wideband (UWB) radars authorized under Sec. 15.515 to operate in the 22-29 GHz band (collectively, ``unlicensed 24 GHz wideband and UWB vehicular radars''). In response to commenters' concerns that ceasing certification of new unlicensed 24 GHz wideband and UWB vehicular radars beginning 30 days after publication of the final rules in the Federal Register, as proposed in the NPRM, would be insufficiently short, the Commission decided it will not certify new unlicensed 24 GHz wideband and UWB vehicular radar equipment on or after one year from the date of publication of the Report and Order in the Federal Register. In response to commenters' suggestions to, at a minimum, harmonize the phase-out of unlicensed 24 GHz wideband and UWB vehicular radars with the phase-out adopted for 24 GHz vehicular radars in the European Union (EU), the Commission decided to allow the manufacture, importation, marketing, sale, and installation of, as well as Class II permissive changes for, previously certified unlicensed 24 GHz wideband and UWB vehicular radar devices until January 1, 2022, consistent with the EU transition plan for 24 GHz vehicular radars. After January 1, 2022, the manufacture, importation, marketing, sale, and installation of, and Class II permissive changes for, these devices for use in the United States, with one limited exception regarding sale and installation for the repair/replacement of defective, damaged, or malfunctioning equipment, will not be permitted. 7. However, as proposed in the NPRM, the Commission decided to permit unlicensed 24 GHz wideband and UWB vehicular radars that are already installed or in use by January 1, 2022 to continue to operate in the vehicle. In that regard, the Commission provided a narrow exception to the phase-out requirements to permit, for the life of the vehicle, the continued sale and installation of unlicensed 24 GHz wideband and UWB radar devices for the exclusive purpose of repairing or replacing defective, damaged, or potentially malfunctioning equipment installed on or before January 1, 2022. This exception is available only when it is not possible to repair or replace the radar equipment designed to operate in the 24 GHz band with radar equipment designed to operate in the 76-81 GHz band, and is limited to the repair and replacement of unlicensed 24 GHz wideband and UWB vehicular radar equipment that has been certified for operation in the 24 GHz band. The Commission expects manufacturers to draw on existing stock of equipment that has been approved before January 1, 2022, but it will address requests for additional relief (e.g., manufacture, importation, or product redesign) on a case-by-case basis. 8. The Commission clarified that the proposal with regard to phasing out use of the 22-29 GHz band for wideband and UWB vehicular radar operations that operate under Sec. Sec. 15.252 and 15.515 of the rules was not intended to apply to unlicensed radars that operate at 24.075-24.175 GHz and 24.0-24.25 GHz under Sec. Sec. 15.245 and 15.249 of the rules, respectively. These rules, which are not being modified, authorize a wide variety of devices that include, but are not limited to, vehicular-specific radars. As such, the Commission will continue to certify radars that operate under these rules and they can continue to be used in vehicular applications. C. Fixed and Other Mobile Radar Operations in the 76-81 GHz Band 9. Fixed Radars Operations. The NPRM proposed to adopt rules that would permit fixed infrastructure radar applications in all or part of the 76-81 GHz band if there was sufficient demand for such uses and studies could support sharing between vehicular and non-vehicular radar applications in the band. Although several commenters expressed interest in deploying fixed radar applications in the 76-81 GHz band at any location, there was substantial disagreement as to whether such applications could successfully coexist with vehicular radars. Many commenters opposed allowing fixed radar operations in the 76-81 GHz band, citing potential interference that could compromise the safe operation of vehicular radar systems. Although commenters asserted that they expected fixed radar manufacturers to design equipment that is technically identical to vehicular radars, the Commission stated that it could not guarantee that this would happen in practice since it neither proposed nor developed a record for the Commission to mandate device specifications and guidelines. Therefore, to prevent non- vehicular fixed radar applications outside of airport locations from causing harmful interference to vehicular radars and provide a more certain environment for the successful migration of vehicular radars to the 76-81 GHz band, the Commission decided to maintain the [[Page 43867]] existing prohibition on non-vehicular fixed radar operations outside of airport air operations areas. 10. However, the Commission recognized the possibility that there may be situations in which fixed radars might be compatible with vehicular radars in the 76-81 GHz band, and did not foreclose exploration of such scenarios. The Commission acknowledged that, under careful coordination, it might be possible for fixed radars to operate in the band at carefully selected locations without causing harmful interference to vehicular radars, but noted that there was insufficient information in the record to develop the specific criteria for a successful coordination process. The Commission stated that it is open to the possibility that specific, limited fixed uses of 76-81 GHz radars outside of airport locations may be possible so long as it can be convinced that such use would not cause harmful interference to vehicular radar operations in the band. 11. Airport Radar Operations. Prior to adoption of the Report and Order, unlicensed FOD detection radar operations were operating as fixed devices in the 76-77 GHz band under part 15 of the rules, and could be authorized as either fixed or mobile devices on a licensed basis under the Commission's part 90 rules in the 78-81 GHz band, in airport air operations areas only. As proposed in the NPRM and supported by the record, the Commission decided to permit fixed and mobile FOD detection radar operations throughout the entire 76-81 GHz band on airport grounds only, under the same technical requirements as those provided for such operations in the 76-77 GHz band in part 15 of the Commission's rules. To minimize the potential for harmful interference to vehicular radar operations from expanded FOD detection radar operations, the Commission maintained the limitation that FOD detection radar operations occur only in airport locations that avoid illumination of public roadways (i.e., in airport air operations areas). This restriction will provide geographic separation between airport-based radar operations and vehicular radar operations on public roads, avoiding any possibility of harmful interference to vehicular radar operations in the 76-81 GHz band. As proposed in the NPRM and supported by the record, the Commission grandfathered for the life of the equipment, or until the supply of existing equipment necessary for maintenance is exhausted, any FOD detection radars that are already installed or in use. If entities want to operate existing FOD detection radars in the 77-78 GHz band, which has not previously been available for FOD detection radar use, such equipment would first have to be certified under the Commission's equipment authorization procedures to operate in the 77-78 GHz band under the part 95 rules. 12. The Commission also permitted the use of aircraft-mounted radar applications, referred to as ``wingtip radars,'' in the entire 76-81 GHz band with the same technical rules as FOD detection radars, as long as they are used in airport air operations areas while aircraft (including helicopters) are on the ground. These radars will be used to prevent and mitigate the severity of aircraft wingtip collisions while planes move between airport gates and runways. The Commission agreed with commenters that aircraft-mounted radar applications can help protect aircraft during taxiing and ground maneuvering, improve airport operations, and provide significant benefits to the airline industry and traveling public, while still protecting vehicular radars from harmful interference. 13. Based on the potential for airborne radar operations to interfere with RAS operations, the Commission decided not to permit the use of aircraft-mounted radars when the aircraft (or helicopter) is airborne. To provide greater assurance that parties will comply with the ground-based restriction for aircraft-mounted radars, the Commission also decided to require that aircraft-mounted radars include an automatic mechanism that discontinues all 76-81 GHz radar functions while the aircraft is airborne, which no commenters objected to, and one commenter indicated is technically feasible. D. Radar Operations in the 76-81 GHz Band Under Part 95 of the Commission's Rules 14. As proposed in the NPRM and supported by the majority of commenters, the Commission consolidated 76-81 GHz radar operations, except for Level Probing Radars (LPRs), under part 95 of the Commission's rules to be licensed-by-rule and protected from interference. Radar applications operating in the 76-81 GHz range will now be governed by Subpart M, The 76-81 GHz Radar Service, in part 95 of the rules. LPRs, which are authorized by Sec. 15.256 to operate in a variety of frequency ranges, including the 75-85 GHz band, and can coexist with vehicular radar operations, will remain authorized to operate on an unlicensed basis. 15. A licensed-by-rule approach under part 95 will provide a level of interference protection to 76-81 GHz radar operations that the Commission's part 15 rules cannot provide since unlicensed users must accept interference from licensed and unlicensed users, whereas under part 95, primary licensed users are protected from interference from secondary and unlicensed users. A licensed-by-rule approach will also reduce the application and licensing burdens associated with authorizing radar operations under an individual license basis, and create time and cost efficiencies for deployment of these important services. Given that FOD detection radar operations are restricted to airport air operations areas that do not have public vehicle access, and considering the narrow beamwidths, highly directional antennas, and large signal propagation losses at relatively short distances of radar operations in the 76-81 GHz band, the Commission saw no need to require licensed FOD detection radars to coordinate with other licensed services or exclude FOD detection radars from part 95 regulation. 16. Technical Rules. As proposed in the NPRM, the Commission adopted technical rules for the newly expanded radar band that mirrored those currently provided for unlicensed vehicular radars and FOD detection radars in the 76-77 GHz band under the part 15 rules. Specifically, the Commission adopted the same average (50 dBm) and peak (55 dBm) EIRP emissions limits for radar applications in the entire 76- 81 GHz band as is currently specified in the part 15 rules for unlicensed vehicular radars in the 76-77 GHz band. The Commission also adopted other technical rules for the newly expanded radar band that mirrored those currently provided under part 15, including unwanted emissions limits, equipment certification, and radiofrequency exposure evaluation. Consistent with the NPRM, the new part 95 rules do not specify distinct spectrum blocks in the 76-81 GHz band for particular radar operations such as LRR and SRR, or FOD detection and aircraft- mounted radars. Instead, the Commission chose to rely on market forces and standardization processes to drive radars use of the band in accordance with application needs and the state of the technology, and decided that interested parties can determine whether particular segments of the 76-81 GHz band should be designated exclusively for LRR or SRR applications, or for FOD detection or aircraft-mounted [[Page 43868]] radars. Neither LRR applications nor aircraft-mounted radars are restricted to operating within a one-gigahertz block of spectrum within the 76-81 GHz band, as suggested by some commenters. 17. Vehicular and FOD detection radars currently certified under part 15 to operate in the 76-77 GHz band need not be recertified under part 95 to continue to operate in the band. These devices may continue their operations, but will now do so on a licensed-by-rule basis and be entitled to interference protection from amateur operations in the 76- 81 GHz band. Any changes for such previously certified devices will need to comply with the applicable part 95 rules. III. Procedural Matters A. Paperwork Reduction Act Analysis 18. This document does not contain any new or modified information collections subject to the Paperwork Reduction Act of 1995 (PRA), Public Law 104-13. B. Congressional Review Act 19. The Commission will send a copy of the Report and Order in a report to be sent to Congress and the Government Accountability Office pursuant to the Congressional Review Act, see 5 U.S.C. 801(a)(1)(A). C. Final Regulatory Flexibility Act 20. The Regulatory Flexibility Act of 1980 (RFA) requires that an agency prepare a regulatory flexibility analysis for notice and comment rulemakings, unless the agency certifies that ``the rule will not, if promulgated, have a significant economic impact on a substantial number of small entities.'' Accordingly, the Commission has prepared a Final Regulatory Flexibility Analysis (FRFA), set forth in Appendix B of the Report and Order concerning the possible impact of the rule changes. IV. Ordering Clauses 21. Accordingly, it is ordered that pursuant to sections 1, 2, 4(i), 301, 302(a), and 303(f) of the Communications Act of 1934, 47 U.S.C. 151, 152, 154(i), 301, 302(a), and 303(f), the Report and Order in ET Docket No. 15-26 is hereby adopted. 22. It is further ordered that parts 1, 2, 15, 90, 95, and 97 of the Commission's rules, 47 CFR parts 1, 2, 15, 90, 95, and 97 are amended, effective October 20, 2017, except as otherwise specified.
