SUMMARY:

This document proposes revisions to the Commission's rules and policies regarding public safety operations in the private land mobile radio services. In the Further Notice of Proposed Rulemaking portion of this document the Commission proposes to reinstate an exemption for 4.9 GHz band applications from coordination via a certified frequency coordinator. Notwithstanding this proposal, the Commission also proposes a licensee-to-licensee coordination requirement for primary permanent fixed stations operating in the 4.9 GHz band. The remaining proposals consist of corrections and clarifications of frequency tables. The Commission makes first proposal because the Commission tentatively concludes that the exemption was deleted by inadvertent omission. The Commission makes the second proposal because it is concerned that the existing coordination rules may not protect primary permanent fixed stations from interference. The Commission proposes the frequency table corrections to fix various errors. The intended effects are to relieve 4.9 GHz band applicants from the cost of certified frequency coordination; ensure sufficient interference protection of 4.9 GHz band permanent fixed primary stations; and eliminate uncertainty regarding the licensing of particular public safety frequencies.

The major proposals in the Further Notice of Proposed Rulemaking are as follows:

  • Reinstate into § 90.175 an exemption for 4.9 GHz band applications from coordination via a certified frequency coordinator.
  • Impose a more formal licensee-to-licensee coordination requirement on primary fixed links in the 4.9 GHz band.
  • Correct and clarify the 4.9 GHz band plan:
  • Amend § 90.1213 by correcting the channel number 14 bandwidth from five megahertz to one megahertz.
  • Amend the table in § 90.1213 to list all the center frequencies that should be used for every possible channel aggregation permitted in the rules.
  • Make three corrections to § 90.20 of the Commission's rules relating to the Public Safety Pool Frequency Table and associated limitations:
  • Amend the § 90.20(d)(66)(i) table of frequency pairs by correcting the mobile-only frequency for Channel MED-4 from 463.075 MHz to 468.075 MHz.
  • Amend § 90.20(c)(3) by replacing limitation 38 with limitation 10 on nine frequencies.
  • Amend § 90.20(c)(3) by replacing the text in the limitation column “O='xl'>72” with the numeral “72.”

4.9 GHz General Exemption From Certified Frequency Coordination

We take this opportunity to address an apparent inadvertent omission of a Commission rule that provided an exemption to 4.9 GHz band applicants from certified frequency coordination. By this Further Notice of Proposed Rulemaking, we seek comment on reinstating the omitted language into the Commission's part 90 rules. When the Commission originally crafted the 4.9 GHz rules, it did not require frequency coordinators to certify applications because “all frequencies will be shared among licensees, and adjacent and co-located licensees are required to cooperate and coordinate in use of the spectrum.” Accordingly, the Commission codified a frequency coordination exemption for applications for frequencies in the 4940-4990 MHz band (4.9 GHz exemption). The 4.9 GHz exemption appeared in the Federal Register entry for the 4.9 GHz Third Report and Order, 68 FR 38635, June 30, 2003, as well as the 2003 and 2004 editions of the Commission's rules on § 90.175(j). However, in 2005 and subsequent editions of the Code of Federal Regulations, the exemption for 4.9 GHz applications was omitted.

The omission of the 4.9 GHz exemption appears to have occurred inadvertently as a result of a rulemaking in 2004. On February 10, 2004, the Commission released a 5.9 GHz Report and Order, 69 FR 46438, August 3, 2004, to revise, inter alia, § 90.175(j) “by adding a new subparagraph (17)” to exempt from frequency coordination “applications for DSRCS [Dedicated Short-Range Communications Service] licensees (as well as registrations for Roadside Units) in the 5850-5925 GHz band” (DSRCS exemption). However, the 2003 Code of Federal Regulations, which was in effect at the time the 5.9 GHz Report and Order was released, already contained seventeen exemptions in § 90.175(j). Because the 5.9 GHz Report and Order stated that it was adding a new subparagraph, we tentatively conclude that the Commission did not intend to delete the 4.9 GHz exemption, then listed as § 90.175(j)(17). We base this tentative conclusion on the lack of any corresponding discussion in the 5.9 GHz Report and Order relating to such a deletion, or any evidence of such an intention in subsequent proceedings. On July 1, 2004, as the result of an unrelated rulemaking, § 90.175 was further revised by removing subparagraph (j)(13) and redesignating subparagraphs (j)(14) through (17) as (j)(13) through (16). On August 3, 2004, Start Printed Page 23818the Federal Register entry for the 5.9 GHz Report and Order was published, 69 FR 46438, August 3, 2004, which overwrote the existing 4.9 GHz exemption in § 90.175(j)(16) with the DSRCS exemption rather than adding a new subparagraph as intended in the 5.9 GHz Report and Order. Subsequently, the omission of the 4.9 GHz exemption was perpetuated through other rulemakings, such as the Commission's Biennial Regulatory Review in 2005. Because there is no evidence that the Commission intended to impose a requirement for certified frequency coordination on applicants in the 4.9 GHz band, we believe that the subparagraph numbering in the 5.9 GHz Report and Order and the subsequent overwriting of the 4.9 GHz exemption were ministerial errors that contributed to the omission.

We find that reinstating the 4.9 GHz exemption would relieve applicants from burdens and fees associated with obtaining certified frequency coordination and would satisfy the Commission's original intent to encourage licensees to cooperate and coordinate with each other in use of the spectrum. In this regard, we tentatively conclude that correcting the error would serve the public interest. However, the omission has been in effect for a substantial period of time, and some entities may be operating under the assumption that formal coordination from a certified frequency coordinator is required for 4.9 GHz applications. We tentatively conclude that correcting the error by restoring the 4.9 GHz exemption would eliminate such uncertainty. Therefore, we seek comment on our tentative conclusion to amend § 90.175(j) to restore the exemption for applications for frequencies in the 4940-4990 MHz band from certified frequency coordination requirements. Notwithstanding this tentative conclusion, we propose a separate, more formal licensee-to-licensee coordination requirement for applications seeking authorization for primary permanent fixed stations, as discussed below.

Coordination for 4.9 GHz Primary Permanent Fixed Stations

As discussed in the Report and Order, we accord primary status to certain permanent fixed point-to-point and point-to-multipoint stations. We are also licensing all permanent fixed point-to-point and point-to-multipoint stations on an individual, site-by-site basis. As we seek to make clear in the previous proposal, 4.9 GHz licensees are not subject to a formal frequency coordination requirement via certified frequency coordinators. Section 90.1209(b) addresses coordination matters by requiring that “[a]ll licensees shall cooperate in the selection and use of channels in order to reduce interference and make the most effective use of the authorized facilities.” We are concerned that the current rule language in § 90.1209(b) may not ensure that applicants for primary permanent fixed stations offer sufficient protection to other primary permanent fixed stations and other co-primary users. Without a specific coordination procedure in place, interference issues may arise between co-primary permanent fixed stations or other co-primary users of the band. We thus believe that additional measures are required to minimize the potential for interference.

Section 101.103(d) presently establishes a prior coordination process that we believe would also serve the application process for primary fixed 4.9 GHz stations. Section 101.103(d) provides that proposed frequency usage of fixed microwave stations must be prior coordinated with existing licensees, permittees, and applicants in the area. The coordination involves two separate elements: notification and response. To be acceptable for filing, all applications and major technical amendments must certify that coordination, including response, has been completed. The notification must specify the names of the licensees, permittees, and applicants with which coordination was accomplished. The notification must include relevant technical details of the proposal. Once notification is provided, affected parties have thirty days to respond. Accordingly, we propose to modify § 90.1209(b) to require applicants for primary fixed stations providing point-to-point and point-to-multipoint communications to successfully complete the prior coordination procedures of § 101.103(d). We seek comment on this proposal. Additionally, we invite commenters to suggest any alternative measures that would serve the purpose of our proposal.

4.9 GHz Band Plan Correction and Clarification

We seek comment on correcting an apparent error in the 4.9 GHz band plan and clarifying which center frequencies may be licensed when aggregating multiple channels into larger bandwidths. The band plan is governed by § 90.1213 of the Commission's rules. First, we identify an error in the bandwidth designated to channel number 14. In the 4.9 GHz Third Report and Order, the Commission decided that “the frequency utilization plan will consist of ten one-megahertz channels and eight five-megahertz channels * * *.” However, in the rule, “[c]hannel numbers 1 through 5 and 15 through 18 are 1 MHz channels and channels [sic] numbers 6 through 14 are 5 MHz channels,” which results in nine one-megahertz channels and nine five-megahertz channels. Accordingly, there is a discrepancy between the Commission's decision and the rule concerning the number of channels designated for each bandwidth.

Channel number 14 is designated as a five-megahertz bandwidth channel in the rules. However, the band edges of its upper neighbors, channel numbers 15 and 16 (each one megahertz wide) are only 0.5 and 1.5 megahertz away, respectively, and the band edge of its lower neighbor, channel number 13 (five megahertz wide) is only 0.5 megahertz away. Therefore, the five megahertz bandwidth of channel number 14 overlaps the bandwidth of channel numbers 13, 15 and 16. Since none of the other channels in the 4.9 GHz band have overlapping bandwidth, we tentatively conclude that the channel plan contains an error in the bandwidth of channel number 14. We propose to correct the channel number 14 bandwidth from five megahertz to one megahertz. We note that this correction would eliminate bandwidth overlap with adjacent channels, improve spectrum efficiency, restore symmetry to the band plan, and result in ten one-megahertz channels and eight five-megahertz channels, consistent with the Commission's intent in the 4.9 GHz Third Report and Order. Also, we propose to grandfather existing licensees to minimize the effect of this rule change on existing operations. We seek comment on this proposed correction.

Finally, the Commission's Universal Licensing System accepts 4.9 GHz channel requests based on the center frequency. The Commission has been receiving applications for aggregated channels on improper center frequencies, which results in inefficient spectrum usage. For example, if a user seeks to aggregate two five-megahertz channels into a ten-megahertz bandwidth, the user might improperly request a frequency centered on one of the existing five-megahertz channels rather than centered in the middle of the desired ten-megahertz channel. The user takes up bandwidth over three or more channels rather than just the two channels that are needed. To resolve this problem, we propose to amend the table in § 90.1213 to list the center frequencies that should be requested for Start Printed Page 23819every possible channel aggregation permitted in the rules. We believe that clarifying the band plan in this manner would improve spectrum efficiency and eliminate confusion over how to license aggregated channels. Also, we propose to grandfather existing licensees to minimize the effect of this clarification on existing operations. We seek comment on this proposal.

Public Safety Pool Corrections

We seek comment on making three “clean-up” amendments to § 90.20 relating to the Public Safety Pool Frequency Table and its associated limitations. The following proposed amendments would rectify three errors that Commission staff has discovered in this rule section since the release of the earlier Notice of Proposed Rulemaking, 72 FR 35190, June 27, 2007, in this proceeding. Although these errors may appear ministerial in nature, they have been in effect for a substantial period of time, and thus, we seek comment on the corrections.

First, in the § 90.20(d)(66)(i) table of frequency pairs, we note that Channel MED-4 has a mobile-only frequency of 463.075 MHz, unlike the other listed channels, which have mobile-only frequencies in the 468 MHz range. We tentatively conclude that 463.075 MHz was a typographical error, and we seek comment on a proposal to correct the mobile-only frequency for Channel MED-4 to 468.075 MHz. The lower half of the MED-4 pair, frequency 463.075 MHz in the base and mobile column, would remain unchanged.

Second, nine frequencies in the Public Safety Pool Frequency Table contain limitation 38; however, § 90.20(d)(38) only contains the text, “[Reserved].” We propose to replace limitation 38 with limitation 10 on those frequencies. In 2005, the Commission issued an order that, inter alia, replaced limitation 38 with limitation 10 in the Public Safety Pool Frequency Table because the two limitations were identical. A portion of the final rule appendix reads: “Section 90.20 is further amended by replacing limitation 38 with 10 in the Public Safety Pool Frequency Table of Section 90.20(c)(3) (Frequencies.) for frequencies 155.325, 155.3325, 155.355, 155.3625, 155.385, 155.3925, 155.4, 155.4075, 462.9375, 462.95625, 462.9625, 462.96875, 462.975, 462.98125, 462.9875, 462.99375, 467.95, 467.95625, 467.9625, 467.96875, 467.975, 467.98125, 467.9875 and 467.99375 * * *.” However, the list erroneously included frequency 462.9375 MHz, which does not have limitation 38, and excluded frequency 462.95 MHz, which has limitation 38. Also, the rule implementation was never completed for the listed frequencies in the 467 MHz range. Therefore, we seek comment on a proposal to complete the rule implementation of the 2005 Biennial Review Report and Order, 70 FR 61049, October 20, 2005, and amend § 90.20(c)(3) by replacing limitation 38 with limitation 10 on the nine frequencies 462.95, 467.95, 467.95625, 467.9625, 467.96875, 467.975, 467.98125, 467.9875 and 467.99375 MHz.

Third, the frequency band 1427-1432 MHz in the Public Safety Pool Frequency Table contains an apparent error in the limitation column. The limitation reads, “O='xl'>72.” We seek comment on a proposal to amend § 90.20(c)(3) by replacing the text in the limitation column “O='xl'>72” with the numeral “72.” This correction would clarify that limitation 72 applies to this band. Limitation 72 reads, “[t]his frequency band is available to stations in this service subject to the provisions of § 90.259,” and § 90.259 contains provisions for the 1427-1432 MHz band.
