2023-14656. Implementation of the Final Acts of the 2019 World Radiocommunication Conference

AGENCY:

Federal Communications Commission

ACTION:

Final rule.

SUMMARY:

In this document, the Federal Communications Commission (Commission) makes non-substantive, editorial revisions to the Commission's Table of Frequency Allocations (Allocation Table), primarily to reflect decisions from the Final Acts of the World Radiocommunication Conference 2019 ( WRC–19 Final Acts). The purpose of this administrative action is to revise the Allocation Table by updating the International Table of Frequency Allocations (International Table) portion of the Allocation Table to reflect the International Telecommunication Union's (ITU's) Table of Frequency Allocations in its Radio Regulations (Edition of 2020) (Radio Regulations), and by making updates and corrections in the United States Table of Frequency Allocations (U.S. Table) portion of the Allocation Table.

DATES:

Effective October 30, 2023.

Synopsis

By this action, the Commission takes the necessary steps to implement certain decisions of the World Radiocommunication Conference held in 2019 (WRC–19). The Commission revises the Allocation Table by updating the International Table of Frequency Allocations (International Table) portion to reflect the International Telecommunication Union's (ITU) Table of Frequency Allocations in its Radio Regulations (Edition of 2020) (Radio Regulations) and by making updates and corrections in the United States Table of Frequency Allocations (U.S. Table) portion. These ministerial actions do not modify or otherwise change the Commission's rules with respect to any party's underlying rights or responsibilities.

The ITU convenes a World Radiocommunication Conference (WRC) typically every three to four years to address international spectrum use. Specifically, the ITU allocates frequency bands to various radio services generally on either a worldwide or regional basis and enters these radio services in its Table of Frequency Allocations (which is reflected in § 2.106 of the Commission's rules as the International Table) as part of the Radio Regulations.

Discussion

By this administrative action, the Commission makes several non-substantive, editorial changes to the Commission's Allocation Table. None of the rule changes discussed in the Order are subject to the notice and comment requirements for rulemaking in the Administrative Procedure Act (APA). Section 553(b)(B) of the APA provides exceptions to the notice and comment requirements for rulemakings when, among other things, the agency finds good cause that the notice and comment requirements are “impracticable, unnecessary, or contrary to the public interest” with respect to the rules at issue. Specifically, the Final Rules consist of conforming changes to and corrects minor errors in the Allocation Table, including removing expired text from domestic footnotes. All of these changes are summarized below. These changes have no substantive effect on industry or the general public. Accordingly, the Commission found that it is “unnecessary,” within the meaning of section 553(b)(B) of the APA, to provide notice and an opportunity for public comment before implementing these rule revisions.

A. Reflecting WRC–19 Revisions in the International Table

The Commission updates the International Table within § 2.106 of the Commission's rules to reflect Article 5, section IV of the Radio Regulations (Edition of 2020), except as revised herein. The International Table is included within the Commission's Allocation Table for informational purposes only. Consistent with past practice, the Commission incorporates the following corrections and updates to the ITU's Table of Frequency Allocations for display as the International Table in § 2.106 of the Commission's rules: First, the Commission updates eight footnotes (5.328B, 5.341A, 5.341B, 5.341C, 5.351A, 5.384A, 5.388, 5.484B) by cross referencing four resolutions (Resolutions 155, 212, 223, 610) that were revised at WRC–19. Next, the Commission: (1) revises two footnotes (5.169A, 5.169B) to make them consistent with the Federal Register 's style used in footnote 5.346 and update the cross reference to Resolution 99 in footnote 5.346 to match the version shown in footnotes 5.169A and 5.169B; and (2) corrects footnotes 5.547 and 5.550E by adding the missing notation “Rev.” and by removing a dash that is inconsistent with 72 other instances of “non-geostationary-satellite systems” in Volume 1 of the Radio Regulations, respectively. Finally, the Commission notes that WRC–19 revised footnote 5.79 by permitting the use of the NAVDAT [navigational data] system to expand the potential uses of the band. Because this is not a non-substantive editorial change to the International Table that affects the U.S. Table, the Commission maintains the status quo of the U.S. Table by replacing the existing reference to footnote 5.79 in the 415–472 kHz, 479–495 kHz, and 505–510 kHz bands within the U.S. Table with that of placeholder footnote US79A. Footnote US79A contains the pre-WRC–19 text of footnote 5.79, except that the Commission lists only the bands where footnote 5.79 currently applies ( i.e., the Commission excludes the 472–479 kHz band, which is no longer allocated to the maritime mobile service, and the 510–525 kHz band, to which the Commission has never applied the provisions of footnote 5.79). The Commission further notes that revised footnote 5.79 applies to the maritime mobile service in the 415–495 kHz and 505–526.5 kHz bands in all ITU Regions; however, a reference to footnote 5.79 is not shown in the 510–525 kHz band within the Region 2 Table and there is no maritime mobile service entry or reference to footnote 5.79 in the 525–526.5 kHz sub-band within the Region 2 Table of the Radio Regulations. Therefore, the Commission adds this footnote 5.79 issue to note 1 of the Commission's Online Table at https://www.fcc.gov/​engineering-technology/​policy-and-rules-division/​general/​radio-spectrum-allocation.Title 47 of the Code of Federal Regulations (CFR) at https://www.ecfr.gov/​current/​title-47 contains the official version of the Table of Frequency Allocations and the FCC Online Table of Frequency is provided for convenience only.

B. Reflecting WRC–19 Revisions in the U.S. Table

WRC–19 deleted one international footnote (5.396) that is referenced in the U.S. Table and revised a resolution that is referenced in two domestic footnotes (US444B, G132). The Commission reviewed the relevant footnotes (5.396, US444B, G132) and found that implementing these changes in the Commission's rules will have no substantive effect on non-Federal operations.

Footnote 5.396 requires space stations in the broadcasting-satellite service (BSS) in the band 2310–2360 MHz operating in accordance with footnote 5.393 that may affect the services to which this band is allocated in other countries to be coordinated and notified in accordance with Resolution 33 (Rev.WRC–15), and further provides that complementary terrestrial broadcasting stations shall be subject to bilateral coordination with neighboring countries prior to their bringing into use. WRC–19 deleted Resolution 33 because the processing of filings under this Resolution was completed prior to WRC–07, and consequently deleted footnote 5.396 after moving its still-relevant text to footnote 5.393. The Commission is updating footnote 5.393 in the International Footnotes to reflect the WRC–19 revisions. See Final Rules. In the United States, BSS operators provide satellite radio service to customers using the 2320–2345 MHz band and footnote 5.393 is not included in the 2310–2360 MHz band of the U.S. Table. The Commission therefore found that removal of footnote 5.396 will have no substantive effect on non-Federal operations. The Commission found that the reference to footnote 5.396 should be removed from the non-Federal Table, consistent with the WRC–19 implementation.

Footnote US444B contains a cross reference to Resolution 418 (Rev.WRC–12). WRC–19 revised Resolution 418 by updating the guidance on the aeronautical mobile service use of the 5091–5150 MHz band by citing to Resolution 748 (Rev.WRC–19), by deleting the invitation that the ITU continue to study the conditions and arrangements for flight testing in this band, and by simplifying its text. Therefore, the Commission found that changing the reference to WRC–19's revision of Resolution 418 will not have any substantive effect on non-Federal operations.

The Commission updates footnote G132, which applies to the 1215–1240 MHz band, to cross reference revised Resolution 608, replacing “(Rev.WRC–15)” with “(Rev.WRC–19).” Resolution 608 pertains to the protection of the radionavigation service in certain countries in Regions 1 and 3; because the United States is located in Region 2, the revision of this resolution will not have any substantive effect on non-Federal operations.

C. Other Revisions to the Allocation Table

The Commission makes the following additional editorial changes to section 2.106 of the Commission's rules:

• Correct the Federal and non-Federal Tables by removing the reference to footnote 5.79A from the 435–472 kHz band because the footnote does not apply to that band.
• Revise footnotes US1, US82, US247, US281, US283, US296, US342, and G115 by changing the references to frequency units from “kHz” to “MHz” and revise footnote G32 from “MHz” to “GHz” in order to make the text of the footnotes consistent with the frequency units shown in the Allocation Table. In each of these footnotes, the Commission also moves the decimal point three spaces to the left and deletes unneeded zeros. In footnote US342, the Commission also corrects a typographical error by changing from “23.07–23.12 GHz” to “23.07–23.12 GHz.”
• Add a space between the third and fourth digits of frequency bands that contain five digits in 28 international footnotes. Specifically, the Commission makes this display change by revising footnotes 5.109, 5.110, 5.111, 5.132, 5.133A, 5.134, 5.145, 5.145B, 5.146, 5.147, 5.149, 5.149A, 5.150, 5.151, 5.152, 5.153, 5.154, 5.155, 5.155A, 5.155B, 5.156, 5.156A, 5.157, 5.158, 5.474D, 5.477, 5.478, and 5.479. This display change is based on the format used in the Radio Regulations. ITU Radio Regulations, Vol. 1, Article 5, at 35–186.

• Simplify the display of facing pages in the Allocation Table. The heading on the top page of the Allocation Table also applies to the bottom page, i.e., every two pages in the Allocation Table are facing pages. The Commission simplifies the display of facing pages in the Allocation Table by ending page 19 on the frequency 52 MHz in the Region 1 Table and on the frequency 54 MHz in all other tables (instead of permitting the entries for the 50–54 MHz band in the combined table for Regions 2 and 3 and the non-Federal Table, and the 50–73 MHz band in the Federal Table, to span pages 19 and 20).

• Remove the references to footnote US108 from the 3300–3500 and 3500–3550 MHz bands in the Federal Table and from the 3300–3450 and 3450–3600 MHz bands in the non-Federal Table and revise footnote G2 by deleting “(except as provided for in US108)” because footnote US108 no longer applies to the 3300–3550 MHz band. Footnote US108 was recently revised to remove the text that applied to the 3300–3550 MHz band. The Commission also moves the reference to footnote US431B from the bottom of the cell to the right of RADIOLOCATION in the 3300–3500 MHz band within the Federal Table because the footnote applies to only the radiolocation service.
• Place footnotes US431B and US433 in ascending numerical order in the 3450–3600 MHz band within the non-Federal Table. On page 39 of the Allocation Table, change the frequency range of the facing pages from “2483.5–3500” to “2483.5–3600” because 3450–3600 MHz is the last frequency band in the non-Federal Table in this set of facing pages.
• Simplify the non-Federal Table by combining the common radiocommunication service entries in the 3600–3650 MHz and 3650–3700 MHz bands to form the 3600–3700 MHz band, move the text of footnote NG185 to footnote NG169, and remove footnote NG185 from the list of non-Federal government (non-Federal) footnotes.
• Simplify the Federal Table by combining the common radiocommunication service entries in the 17.8–18.3 GHz and 18.3–18.6 GHz bands to form the 17.8–18.6 GHz band.
• Correct the placement of footnote NG65 in the non-Federal Table in the 24.75–25.25 GHz and 47.2–48.2 GHz bands by moving the footnote reference from the right of the fixed-satellite service (Earth-to-space) entry to the bottom of the cell because this footnote refers to three allocated services. For consistency in the Allocation Table, the Commission employs the following rules for footnote placement in both the International and U.S. Tables: The footnote references that appear below the allocated service or services apply to more than one of the allocated services, or to the whole of the allocation concerned. The footnote references that appear to the right of the name of a service are applicable only to that particular service. 47 CFR 2.104(h)(5)–(6).

• Correct footnotes 5.430A, 5.458, 5.509D, and 5.547 to reflect their text as shown in the Radio Regulations (ITU Radio Regulations, Vol. 1, Article 5, at 122, 132, 150, and 164). Specifically, the Commission corrects footnotes: (1) 5.430A by deleting the last sentence ( i.e., “This allocation is effective from 17 November 2010.”); (2) 5.458 by changing from “6425–7025 MHz” to “6425–7075 MHz” in the last sentence; (3) 5.509D by changing from “19000” to “19 000” in the last sentence; and (4) 5.547 by changing from “Resolution 75 (WRC–12)” to “Resolution 75 (Rev.WRC–12).”

• Revise footnote US52 to account for now-expired text. Footnote US52 states that use of the frequencies 156.775 MHz and 156.825 MHz by the mobile-satellite service (Earth-to-space) is restricted to the reception of long-range Automatic Identification System (AIS) broadcast messages from ships. It also provided, in the text of the footnote, for port operations and ship navigation communications on these two frequencies (AIS 3 and AIS 4) until August 26, 2019. The Commission revises footnote US52 paragraph (b) to remove the reference to August 26, 2019. Previous port operations and ship navigation communications on these two frequencies (AIS 3 and AIS 4) expired on August 26, 2019 and are no longer permitted.

• Revise footnotes US100, US312, and NG33 to remove footnote text that pertains to dates that have passed ( i.e., expired text). Specifically, the Commission updates footnote US100 by removing the expired text in paragraph (b) providing that the 2345–2360 MHz band would be available for non-Federal aeronautical telemetering and associated telecommand operations for flight testing of aircraft and missiles until January 1, 2020; updates footnote US312 by limiting the use of the frequency 173.075 MHz by all stolen vehicle recovery systems to an authorized bandwidth not to exceed 12.5 kilohertz and striking language regarding operations on 20 kilohertz that expired on May 27, 2019; updates footnote NG33 by removing the expired text in paragraph (a), i.e., the transition period for full-power and Class A television (TV) station and fixed TV broadcast auxiliary station operations in the 614–698 MHz band has concluded and the band is now used predominately for mobile broadband services. The Commission also corrects a typographical error, i.e., white space devices may operate in the 657–663 MHz band in accordance with § 15.707(a)(2), instead of paragraph (a)(4), and simplifies the text of the footnote.

Paperwork Reduction Act Analysis

This document does not contain new or modified information collections subject to the Paperwork Reduction Act of 1995 (PRA), Public Law 104–13 (44 U.S.C. 3501–3520). In addition, it does not contain any new or modified information collection burden for small business concerns with fewer than 25 employees pursuant to the Small Business Paperwork Relief Act of 2002, Public Law 107–198, see44 U.S.C. 3506(c)(4).

Congressional Review Act

The Commission has determined, and the Administrator of the Office of Information and Regulatory Affairs, Office of Management and Budget, concurs, that this rule is “non-major” under the Congressional Review Act, 5 U.S.C. 804(2). The Commission will send a copy of this Order to Congress and the Government Accountability office, pursuant to 5 U.S.C. 801(a)(1)(A).

Administrative Procedure Act Requirements

None of the rule changes discussed in this Final Rule are subject to the notice and comment requirements for rulemaking in the Administrative Procedure Act (APA). Section 553(b)(B) of the APA provides exceptions to the notice and comment requirements for rulemakings when, among other things, the agency finds good cause that the notice and comment requirements are “impracticable, unnecessary, or contrary to the public interest” with respect to the rules at issue. The changes discussed in this Final Rule have no substantive effect on industry or the general public. Accordingly, the Commission finds that it is “unnecessary,” within the meaning of section 553(b)(B) of the APA, to provide notice and an opportunity for public comment before implementing these rule revisions. Because the rule changes are being implemented without notice and comment, the Regulatory Flexibility Act, 5 U.S.C. 601 et seq., does not apply.

Ordering Clause

It is ordered that, pursuant to sections 1, 4(i), 4(j), 7, 301, 303(c), 303(f), and 303(r) of the Communications Act of 1934, as amended, 47 U.S.C. 151, 154(i), 154(j), 157, 301, 303(c), 303(f), and 303(r), this Order is adopted.

It is further ordered that the amendments of part 2 of the Commission's rules, as set forth in Appendix A of the Order, are adopted, effective thirty (30) days after publication in the Federal Register .
