Federal Communications CommissionDA 13-431 Before the Federal Communications Commission Washington, D.C. 20554 In the Matter of Implementation of Sections 309(j) and 337 of the Communications Act of 1934 as Amended Promotion of Spectrum Efficient Technologies on Certain Part 90 Frequencies ) ) ) ) ) ) ) WT Docket No. 99-87 RM-9332 ORDER Adopted: March 15, 2013Released: March 18, 2013 By the Chief, Wireless Telecommunications Bureau, Chief, Public Safety and Homeland Security Bureau, and Chief, Office of Engineering and Technology: 1.Introduction.In this Order, we grant in part and deny in part a Petition to Delay Indefinitely Implementation of Section 90.203(j)(5) of the Commission’s Rules filed by Ritron, Inc. (Ritron) on September 21, 2012. 1 Pursuant to Section 90.203(j)(5) of the Commission’s rules, the Commission no longer accepts applications for certification of Part 90 private land mobile radio (PLMR) equipment in the 150-174 MHz and 450-512 MHz bands that cannot operate in a 6.25 kHz mode or with equivalent efficiency. 2 Ritron requests that implementation of this requirement be delayed indefinitely. We conclude that the requirement should be waived only until January 1, 2015. 2.Background.In 1995, the Commission adopted rule changes to promote the efficient use of the PLMR service and facilitate the introduction of advanced technologies. 3 To promote the transition to a more efficient narrowband channel plan, the Commission provided, inter alia, that “only increasingly efficient equipment” would be approved. 4 The Commissiondid not set a date after which it would no longer approve equipment with a wideband (25 kHz) mode, or after which such equipment could no longer be manufactured or used. 5 The Commission contemplated that, as systems reached the end of their service life and new radios were needed, users would migrate to the narrower bandwidth multi-mode radios in order to avoid the adjacent-channel interference that could occur from systems using the adjacent narrowband channels. 6 3.Subsequently, the Commission determined that the 1995 rules failed to provide adequate incentive to realize the Commission’s spectrum efficiency goals in these bands, and stronger measures 1 SeePetition to Delay Indefinitely Implementation Section 90.203(j)(5) of the Commission’s Rules (filed Sept. 21, 2012) (Petition). 2 See47 C.F.R. § 90.203(j)(5). 3 SeeReplacement of Part 90 by Part 88 to Revise the Private Land Mobile Radio Services and Modify the Policies Governing Them, Report and Order and Further Notice of Proposed Rule Making, PR Docket No. 92-235, 10 FCC Rcd 10076, 10077 ¶ 1 (1995). 4 Id.at 10081 ¶ 7. 5 Id.at 10100 ¶ 40. 6 Id. Federal Communications CommissionDA 13-431 2 would be required to bring about a timely transition to narrowband technology. 7 The Commission therefore amended the rules to provide that, by January 1, 2013, Industrial/Business and Public Safety Radio Pool licensees in the 150-174 MHz and 421-512 MHz bands must migrate to 12.5 kHz channel bandwidth or utilize a technology that achieves equivalent efficiency. 8 4.The Commission also adopted interim deadlines to facilitate this transition to narrowband technology. Among other rules, the Commission provided that, beginning January 1, 2011, it would no longer accept applications for certification of equipment that cannot operate in 6.25 kHz mode or with equivalent efficiency. 9 In 2010, the Commission temporarily waived this requirement until January 1, 2013, 10 but stated, “If 6.25 kHz standards still are not in place at that date, interested parties may request a further extension.” 11 5.Ritron, a manufacturer of wireless products, contends that standards for 6.25 kHz technology are not yet in place and that other issues exist that justify delaying implementation of mandatory 6.25 kHz certification by manufacturers.Ritron states that no one 6.25 kHz equipment standard exists and that, in the Industrial/Business sector of the market, two incompatible and proprietary technologies have emerged. 12 Italso argues that 6.25 kHz equipment is still unduly expensive. 13 Finally, Ritron asserts that using the equipment authorization process to facilitate the transition to narrowband technology has been largely unsuccessful. 14 Itconcludes that the implementation of Section 90.203(j)(5) should be delayed until (a) a real need has been established for additional PLMR frequencies beyond those created by the transition to 12.5 kHz channels; (b) the benefits of 6.25 kHz outweigh the associated research and development, manufacturing, and product costs; and (c) a standard has emergedfor a more cost-effective voice compressor/decompressor (vocoder). 15 6.The Wireless Telecommunications Bureau, Public Safety and Homeland Security Bureau and the Office of Engineering and Technology sought comment on Ritron’s request. 16 We asked commenters to address whether the public interest would be served by further delaying implementation of 7 See Implementation of Sections 309(j) and 337 of the Communications Act of 1934 as Amended,Second Report and Order and Second Further Notice of Proposed Rulemaking, WT Docket No. 99-87, 18 FCC Rcd 3034, 3038 ¶ 12 (2003). 8 See 47 C.F.R. § 90.209(b)(5). The January 1, 2013 deadline for converting to 12.5 kHz technology has been waived for licensees in the 470-512 MHz segment of the UHF band (the T-Band). SeeImplementation of Sections 309(j) and 337 of the Communications Act of 1934 as Amended, Order, WT Docket No. 99-87, 27 FCC Rcd 4213 (T-Band Order), on recon., Order on Reconsideration, 27 FCC Rcd 14770 (WTB/PSHSB/OET 2012). 9 See Implementation of Sections 309(j) and 337 of the Communications Act of 1934 as Amended,Third Report and Order, WT Docket No. 99-87, 22 FCC Rcd 6083, 6090 ¶ 16 (2007) (Third Report and Order). 10 See Implementation of Sections 309(j) and 337 of the Communications Act of 1934 as Amended, Order, WT Docket No. 99-87, 25 FCC Rcd 8861, 8866 ¶ 11 (2010) (Order). 11 Id.at 8866 n.41. 12 …
