INTRODUCTION ă  R-1.` ` By this Second Notice of Inquiry (Second NOI), the Commission reviews  R-comments and replies submitted in response to the Notice of Inquiry (Notice) N6-#&d2PG;F&P##&Q2PQF&P#э Notice of Inquiry, IC Docket No. 9431, 9 FCC Rcd 2430 (1994). in this proceeding and reviews the recommendations of the WRC95 Industry Adivisory Committee (IAC). It also seeks comment on preliminary proposals for the 1995 World Radiocommunication Conference (WRC) and future WRCs.  RJ-2.` ` The International Telecommunication Union (ITU) will convene WRC95 from October 23, to November 17, 1995, at its headquarters in Geneva, Switzerland. The agenda for the conference includes substantive topics such as facilitating the introduction of global mobilesatellite services (MSS) and simplifying the international Radio Regulations. It also includes further consideration of an agenda for the next conference, WRC97, and drafting a preliminary agenda for WRC99. Presentation of the Commission's preliminary views on these topics is intended to stimulate discussions and is part of an overall effort to achieve early consensus on U.S. proposals to WRC95. The preliminary proposals described below are subject to modification, however, and the Commission's further development of its proposals will  Rd-include consideration of comments received in response to this Second NOI and of additional recommendations of the IAC. The Commission's ultimate recommendations for U.S. proposals will be released in a Final Report prior to WRC-95.  R-yH II. BACKGROUND ă  R-3.` ` World Radiocommunication Conference (WRC) Schedule. In the Notice,mh N-#&Q2PQF&P#э Id. at 2430.m we described the ITU's adoption (in conjunction with a major restructuring) of a fouryear planning cycle for WRCs that are now to be convened every two years to consider radiocommunication matters of worldwide character, including frequency  Ri-allocations and allotment plans.i N" -#&Q2PQF&P#э See Article 4B, Convention of the ITU, Final Acts of the Additional Plenipotentiary  N -Conference (Geneva, 1992). Each WRC also develops, subject to the approval of Council, an agenda for the next conference and recommends a preliminary agenda for  R;-the WRC four years hence.; Nl$-#Xm2PG;DFXP##&Q2PQF&P#э See Resolution No. 9, Final Acts of the Additional Plenipotentiary Conference, (Geneva, 1992). Thus, in addition to the substantive topics to be covered at WRC95, U.S. proposals are now being developed to propose additional items for the WRC97 agenda and for the preliminary agenda of WRC99, which could include" 0*((," initial views toward an agenda for WRC2001.  R-4.` ` Notice of Inquiry. This proceeding addresses technical and regulatory matters related to the agenda for WRC95, and solicits information to assist the  R-Commission in preparing cogent U.S. proposals for that conference. The initial Notice briefly reviewed the results of WRC93 and its recommendations for WRC95, including: review of the Radio Regulations based on the Final Report of the Voluntary Group of Experts (VGE); facilitating use of frequency bands allocated at WARC92 to the mobilesatellite service (MSS); and review of other selected topics, including future  R1-agendas.u1 N -#&Q2PQF&P#э WRC Notice, at 2430.u In the Notice we invited comment on these matters and also on certain procedural matters relating to ways in which the Commission might best structure its own processes to be responsive to industry needs and, in light of the ITU's new quadrennial conference planning cycle, to ensure timely and effective planning for future WRCs.  R -5.` ` WRC95 Industry Advisory Committee. Shortly after the release of the  R-initial Notice, the Commission established the WRC95 IAC to develop independent private sector proposals for consideration by the Commission in parallel with this  Rb-proceeding.bh N{-#&Q2PQF&P#э  See Public Notice, Notice of Advisory Committee Establishment, released May 25,  NS-1994; see also WRC Notice, at 2438. The IAC, which is chaired by a member of the private sector and includes experts from industry, is comprised of six Informal Working Groups (IWGs) studying issues of regulatory procedures for coordination, MSS below 1 GHz, MSS above 1 GHz, MSS feeder links, space sciences, and future conference agendas. IAC and IWG meetings are announced by Public Notices and all interested members of the public are encouraged to attend.

The IAC Interim Report has  N-been associated with the docket in this proceeding. See News Release, released January 30, 1995. The results of the IAC's work are being fully considered by the Commission which will, in consultation with the Department of Commerce's National Telecommunications and Information Administration (NTIA) and the Department of State, develop final U.S. proposals for WRC95. "7 0*((="  R-K III. DISCUSSION ă  R-6.` ` WRC95 will be the first conference under the ITU's new conference planning cycle to discuss substantive spectrum allocation and regulatory matters. This conference represents a significant opportunity to build a foundation for advancing near and longterm United States telecommunications goals. In particular, WRC95 is critical to a new commercial telecommunications industry the mobilesatellite  Ra-services (MSS) industry, that includes lowEarth orbit (LEO) MSS systems.}a N-#&Q2PQF&P#э See Report and Order in CC Docket No. 92166, Amendment of the Commission's Rules to Establish Rules and Policies Pertaining to a Mobile Satellite Service in the 1610 N -1626.5/2483.52500 MHz Frequency Bands (Big LEO Report), 9 FCC Rcd 5936 (1994).} LEO systems can provide voice, data and other services at relatively low cost and will be a critical component in achieving the Commission's goals of universal service, open access and competition in the provision of services. They will also be part of a new seamless, nationwide (and eventually global) communication network. The new MSS industry also promises to stimulate significant economic growth both domestically and  R -abroad.p  N-#&Q2PQF&P#э Id. at 594041.p The proposals here are intended to facilitate implementing competitve MSS operations by easing international technical and regulatory constraints and providing additional spectrum allocations.  R{-7.` ` In addition to seeking comment on specific MSS proposals, we invite  Rd-input on other subjects raised in the first Notice. These topics include: various space service allocation matters; review of Appendices 30 and 30A; availability of high frequency broadcasting bands (HFBC); the Final Report of the VGE; and agendas for  R-WRC97 and for the 1999 and 2001 WRCs.  N-#&Q2PQF&P#э See WRC Notice, at 2431. Commenters should also consider the longrange planning aspects of the ITU's conference cycle the twoyear WRC schedule and fouryear WRC planning cycle. In that regard, parties should comment  R-on topics not addressed in the first Notice, or here, that may be appropriate for conferences beyond WRC97.

PP-#Xm2PG;DFXP# A.Mobile Satellite Service Issues  R"-8.` ` At WRC95, the United States will have the opportunity to improve the use of existing MSS bands by eliminating technical, operational, and regulatory barriers; by making available adequate, useable feeder link spectrum to support MSS user links; and by adopting limited new MSS allocations. These measures should  R -provide significant relief to MSS proponents worldwide. In the Notice, we solicited" o 0*((!"  R-comment on these points without addressing specific details.O  Ny-#&d2PG;F&P#э See id. at 243335. An exception to our general solicitation is the issue of RR 2613 that addresses the status of nonGeostationary (NGSO) MSS feeder link use of FSS spectrum  N)-(id. at 2434, para. 24). O Identification of specific concerns was left to interested parties and the IAC. Since then, ITU Radiocommunication Sector (ITUR) Task Groups 8/3 and 4/5, that addressed MSS and MSS feeder links respectively, have concluded their work and will report to the 1995 Conference Preparatory Meeting (CPM) technical and procedural bases for  R-consideration of MSS issues at WRC95. 8 NV -#&d2PG;F&P#э Task Group 8/3, Study Group 8 Preparation for Conference Preparatory Meeting 1995 (CPM95), met from Nov. 17 to 25, 1994. Task Group 4/5, Feeder Links for the Mobile Satellite Service, met from Nov. 24 to 30, 1994. During the same period Task Group 2/2, that deals with interservice sharing issues, addressed some aspects of MSS sharing with other services. For each major issue, discussion is broken down into issues relative to MSS Below 1 GHz followed by issues relative to MSS  R_-Between 1 and 3 GHz. _  N(-#&Q2PQF&P#э The exception is the discussion of feeder link issues. Feeder link issues here are germane only to MSS Between 1 and 3 GHz.  R1-9.` ` This Second NOI includes discussion and consideration of some frequency bands that are allocated exclusively for federal government use and other bands that are shared coequally between the private sector and the federal government agencies. Opposition to preliminary nongovernment MSS proposals for some of these bands has been expressed by NTIA and, through NTIA's Interdepartment Radio Advisory Committee (IRAC), by the government agencies. FCC WRC95 proposals for these bands will be the subject of detailed discussions between the Commission and NTIA. U.S. proposals to WRC95 and to future WRCs ultimately require agreement among the FCC, NTIA and the Department of State.  RK- 10.` ` WRC95 provides an opportunity to review technical constraints associated with MSS frequency bands below 3 GHz and to review any associated provisions, resolutions and recommendations. Parties to this proceeding, relevant ITUR Task Groups and the IAC have identified such constraints whose removal or modification would improve the use of frequency bands allocated for MSS.  R- 11.` ` Constraints identified thus far fall into general categories: 1) technical constraints, such as those that specify the maximum power a satellite beam can  R-produce at the Earth's surface}  N%-#&d2PG;F&P#э Stated in terms of power flux density (PFD).} devised presumably to assist sharing spectrum with other services, or to determine if and where coordination with services of other administrations is required; or, constraints that limit the radiated power emitted from"e0 0*((l" MSS earth stations; 2) allocation constraints on existing MSS allocations, such as those that limit MSS networks to a lower allocation status, to certain categories of  R-service or to certain geographic areas; NK-#&d2PG;F&P#э These types of constraints are discussed briefly and also are summarized in the MSS spectrum allocation proposal tables in paragraphs 56 and 57. and 3) regulatory/procedural constraints, particularly those relating to nongeostationary orbit (NGSO) MSS coordination procedures. Our discussion on these issues is divided into two sections. Parties should bring to our attention any constraints not identified whose removal would ease use of frequencies for MSS (either below 1 GHz or between 1 and 3 GHz).  RH-1. Constraints on MSS Below 1 GHz  R - 12.` ` Technical Constraints. Radio Regulation No. 608A (RR 608A) requires that the power flux density (PFD) of MSS mobile earth terminals (METs) operating in  R -the 148149.9 MHz band not exceed 150 dB (W/m2/4kHz) outside of the licensing administration's borders. This restraint poses both operational and regulatory difficulties. The limit as written cannot be complied with strictly, yet it appears that this is an absolute limit on the acceptable PFD of the METs instead of a coordination trigger.  Rb- 13.` ` As in the case of footnote RR 608A, RR 608B imposes a PFD limit of  RK-150 dB (W/m2/4kHz) for METs in the 149.9150.05 MHz band. This limit was devised to protect terrestrial fixed and mobile services from harmful interference from MET operations. This band, however, has no terrestrial allocations, and is shared with no terrestrial services.  R- 14.` ` Below 1 GHz MSS proponents suggest that the United States work to remove both the RR 608A and RR 608B PFD limits. STARSYS Global Positioning. Inc. (Starsys) states that because radiofrequency transmissions do not stop at international borders, the RR 608A and 608B requirements are impractical. Starsys contends that those requirements should either be removed or apply in instances  Re-where potential interference situations cannot be resolved between administrations.ge@ NV-#&d2PG;F&P#э Starsys comments at 5.g  RN-The IAC proposes that the 150 dB (W/m2/4kHz) PFD limit be eliminated, and replaced with an appropriate coordination triggering mechanism. Specifically, the IAC recommends that countries wishing to implement MSS systems be compelled to coordinate MET operations with administrations falling within a specified threshold  R-distance of the implementing country's borders. N%-#&d2PG;F&P#э A method for calculating the threshold distance is described in ITUR Document 83/TEMP/45E (Geneva, 1994). With regard to RR 608B, the IAC notes that this limit was devised to protect terrestrial fixed and mobile services from"X0*((*!" harmful interference from MET operations. This band, however, has no terrestrial allocations, and is shared with no terrestrial services. Accordingly, the IAC states that  R-this footnote is unnecessary and recommends that it be eliminated.p NK-#&d2PG;F&P#э IAC Interim Report at 62.p  R-15.` ` We agree that RR 608A and RR 608B would cause unnecessary difficulties in implementing NVNG systems. We believe in this case that PFD limits would be best negotiated between affected admistrations and would likely vary depending on the circumstance. We accept the IAC's recommendation and propose to eliminate RR 608A in favor of the coordination threshold distance methodology referenced above, and we propose to modify RR 608B as set forth in Proposal No. 2/LLEO, Appendix 1.  R -16.` ` Allocation Constraints. Within the band 137138 MHz space research and meteorological satellite (MetSat) operations have primary status. MSS has coprimary status in the 137137.025 MHz and 137.175137.825 band segments, and secondary status elsewhere. In the U.S., the National Oceanic and Atmospheric Administration (NOAA) has indicated it has worldwide commitments to operate in these bands at least until the year 2006 and will have continuing operations until  Rb-around the year 2010.bh N{-#&d2PG;F&P#э In October 1994, Congress mandated that DoD and NOAA combine their polar orbiting meteorological satellite programs. This convergence, as well as the potential convergence with similar European meteorological satellite programs, is in the planning stage and the characteristics and frequencies of operation of new satellites are not defined. Consequently, the time frame for migrating meteorological satellites from the 137137.025 MHz and 137.175137.825 MHz band segments is still under discussion. Therefore, the years 2006 and 2010, referenced in the text above, appear in square brackets in the attached proposal for the 137138 MHz band.  R4-17.` ` The IAC recommends phasing out MetSat operations in the 137.175137.825 MHz segments of the 137138 MHz band where MSS now has coprimary status. It proposes a new footnote to the international table that will provide a coprimary status for MetSats until 2006 and a secondary status until 2010. This recommendation would provide for MetSat needs while later providing less encumbered spectrum for MSS. We note that the situation is similar for the 137137.025 MHz portion of the band. We accept the IAC's recommendation, but also extend the IAC's proposal to the 137137.025 MHz band, noting that the time frame for migrating MetSats has not been finalized. We invite comment on this proposal set forth in Proposal No. 2/LLEO, Appendix 1. We also invite parties to comment on whether there is continued need for the space operation and space research alloctaions that also have coprimary status throughout the 137138 MHz band. "  0*(("Ԍ R-18.` ` At WARC92 the band 149.9150.05 MHz was allocated to the land mobilesatellite service on a coprimary basis. The IAC has recommended that this allocation be redesignated to a generic mobilesatellite service. Below 1 GHz MSS proponents have noted that services they intend to provide would extend beyond strictly "land mobile" offerings and could include maritime and possibly aeronaurical offerings. Their view is that potential service offerings should not be limited  Rv-needlessly.kv N-#&d2PG;F&P#э Orbcomm comments at 1011.k  RH-19.` ` We continue to believe that generic MSS allocations afford operators maximum flexibility in introducing needed services. This is particularly important in the case of a service such as MSS that require a large initial capital outlay. Without the flexibility of generic allocations, providers may not find it economically feasible to launch systems devoted strictly to discrete applications. In addition, we note that this proposal aligns with the VGE's recommendations that service allocations be made as  R -broadly as possible. h N-#&d2PG;F&P#э In this regard we note that the IAC recommends that, in light of recent sharing techniques identified in TG 8/3, countries should reconsider the need for RR 608C. This footnote to the 148149.9 MHZ bands states that MSS shall not cause harmful interference to, nor claim protection from stations of the fixed or mobile services in approximately 70 countries. Eliminating RR 608C would align with the VGE's attempt to eliminate countryspecific footnotes to the Table of Frequency Allocations. We request comment on this  N-recommendation. See IAC Interim Report at 62. Additionally, there is a consequential change to RR 599B. This change removes the 'land mobilesatellite' limitation.  Therefore, we accept the IAC's recommendation and propose that the 149.9 150.05 MHz band be allocated to MSS generically as given in Proposal No. 2/LLEO. Comment is invited.  Rb-2. Constraints on MSS Between 1 and 3 GHz  R4-20.` ` Technical Constraints. In the band 16101626.5 MHz, RR 731E stipulates that MSS mobile earth stations (MES) shall protect stations operating in accordance with RR 730 and RR 732. To protect stations operating pursuant to  R-ԊRR 732,C u N -#&Q2PQF&P#э RR 732 reserves the 16101626.5 MHz band on a worldwide basis for the use and development of air navigation and directly associated terrestrial or satellitebased facilities. It also provides that any satellite use of the band is subject to agreement under the procedures of Article 14 of the international Radio Regulations. Pursuant to the international Radio Regulations, MSS stations may not cause harmful interference to or claim protection from stations operating in accordance with RR 732.C MESs are limited to an e.i.r.p. of 15 dB (W/4 kHz) in those parts of the band where such stations operate. In other parts of the band, MESs can operate up to an eirp of 3 dB (W/4kHz). However, RR 731E does not specify whether these levels correspond to peak or mean values.

Pursuant to the international Radio Regulations, MSS stations may not cause harmful interference to or claim protection from stations operating in accordance with RR 730.L In its Interim Report, the IAC argues that RR No. 953 provides sufficient recognition of the need to protect  R -radionavigation services operating in the band.+ Xu N -#&Q2PQF&P#э Radio Regulation 953 of Article 9 cautions administrations that special heed be given to the safety aspects of radionavigation and other safety services when making assignments in bands in which those services operate.+ The MSS parties and the IAC recommend that this apparently contradictory text be deleted.

We also agree that RR No. 953 provides appropriate and sufficient recognition of the need to protect safety services operating in accordance with RR No. 732. With regard to fixed services operating in accordance with RR No. 730, we believe that sufficient protection can be afforded to these services in the coordination process. Consequently, we propose to delete the last sentence of RR 731E and replace it with text noting that the  R-application of RR No. 953 applies in the 16101626.5 MHz band.

In its Interim Report, the IAC states that RR 733E was originally adopted at WARC87 to protect RAS when RAS had a secondary status worldwide and RDSS was being introduced on a secondary basis. The IAC claims that since RAS has been made primary in the subject bands by WARC92, special recognition bestowed upon RAS by WARC87 is no longer needed. Further, it claims that RR 733E creates confusion and ambiguity with regard to the status of MSS and RDSS in  R -the 1610.61626.5 MHz band.

With respect to terrestrial stations, coordination is required only if the space station PFDs at the Earth's surface exceed limits established in RR No. 2566.  R-29.` ` NGSO MSS proponents contend that RR No.2566 PFD values should be regarded as a "trigger" value for coordination rather than absolute limits. Further, those proponents argue that the current PFD levels should be increased, as it is likely that their systems can operate at higher PFD levels without causing interference to  R_-terrestrial systems.8"_u N-#&d2PG;F&P#э For example, with regard to specifying the RR 2566 limits as coordination triggers, Constellation states that above 1 GHz NGSO MSS operators intend to operate globally and that therefore it is desirable to set a coordination trigger at a level that would obviate the need for operational systems to coordinate with every country in the world. Constellation comments at 5. With regard to revision of PFD levels, Loral contends that its recent analysis shows that a typical CDMA NGSO MSS system operating at PFD levels higher than those specified in RR 2566 would not cause interference to terrestrial services. Loral proposes to replace the reference to RR 2566 in RR 753F with PFD values it provides in its comments. Loral comments at 13.8   R1-30.` ` The IAC notes that since RR 753F was adopted at WARC92, substantial analyses have been undertaken that show the RR No. 2566 PFD limits are unduly restrictive.

Task Groups 8/3 and 4/5 have analyzed the sharing situation between MLS and NGSO MSS feeder links and have indicated that sharing may be feasible given certain constraints. However, Task Group 4/5 recommends that, given the safety aspects of MLS, the two services use nonoverlapping spectrum. Additionally, Task Group 4/5 notes that MLS could be 'reorganized' in the future into the 50005120 MHz portion of the band. This  NX-would yield 130 MHz of nonoverlapping, contiguous spectrum that could be used for NGSO MSS feeder links. See ITUR Document 45/Temp/38 (Rev.1) at 2.1.3.8.1.1.

Nonvoice, nongeostationary MSS proponents who intend to operate below 1 GHz have indicated a need for at least an additional 10 MHz of spectrum, available for network use by the year 2000, and for an additional 1320 MHz by the year 2010. The IAC identified candidate bands that may be suitable for these operations and recommends seeking an allocation of 10 MHz of spectrum at WRC95. The bands it identified are listed in the table in Appendix 2.  R -857.` ` While the proposed bands total more than 10 MHz, the identification of a number of candidate bands will likely be necessary to ensure the worldwide allocation of 10 MHz at WRC95. Note that the IAC has prioritized candidate bands into three categories. They are:  R4-Priority One {bands the IAC considers as most desirable for allocation in the near term and on a worldwide basis;(#  R-XPriority Two {bands where NVNG MSS can share with existing services, however, achieving worldwide allocations might be difficult; and(#  R-XLowest Prioritybands used heavily in the U.S. However, the nature of existing operations might permit sharing.(#  RN-The priorities above are the IAC's assessment of the potential for using the bands it identifies. We note that all of the 'Priority One' bands for which the IAC has submitted  R -draft conference proposals are either allocated exclusively for government use or for shared government nongovernment use. NVNG MSS use of these bands has not been coordinated or agreed upon among the FCC, NTIA or government agency users. Therefore, it is premature to indicate that these bands will be U.S. proposals to WRC95. We invite parties to comment on potential NVNG MSS allocations in the bands in  R!-the table, particularly the 'Priority One' bands,X`!hа N%-#&Q2PQF&P#э The IAC's 'Priority One' bands are: 138141 MHz (spacetoEarth) and 141144 MHz (Earthtospace); 225235 MHz (spacetoEarth) and 390.0399.9 MHz (Earthtospace); 312315 (Earthtospace) and 387390 MHz (spacetoEarth); and 399.9400.05 MHz (both"v'W0*(('" directions). With regard to the 380399.9 MHz spectrum range, we note that in Europe and the United States, some entities have indicated a desire to reserve any nonmilitary use for  N@-land mobile public safety services (see para. 104, infra.). We invite comment on the ability of NVNG MSS to share with existing and future fixed and mobile services in this spectrum. noting that, with the exception of the"!X0*((" " 399.9400.05 MHz band, such use has not been coordinated or agreed upon between the FCC and NTIA. We also invite parties to identify and give consideration to  R-potential below 1 GHz NVNG MSS allocations in nonGovernment spectrum. Y8а Ns-#&d2PG;F&P#э For example, we note that the IAC includes the 470512 MHz and 512806 MHz bands under its 'Priority Two' categorization as possible candidates for NVNG MSS allocations in the long term. In the United States, these bands are allocated for television broadcasting. For these bands, we invite parties to comment on the technically feasibility of spectrum sharing between NVNG MSS and both existing analog and future digital television broadcasting. Additionally, recognizing that it may be difficult to agree on U.S. proposals for allocations in spectrum with primary Government allocations, parties should attempt to identify potential allocations that might use both Government and nonGovernment  Rv-spectrum. Z8v а N-#&Q2PQF&P#э For example, it is usually necessary to have a certain percentage of frequency separation for send and receive transmissions. Given that a NVNG MSS allocation around 400 MHz is desirable and a frequency separation on the order of 57% is needed, would it be possible to obtain allocation in the 380400 MHz range for one transmission direction with a companion allocation in the 420450 MHz range? Parties should identify such possibilities.   RH-958.` ` Two of the IAC's candidate bands are being included as preliminary FCC proposals for WRC95. One, the 399.9400.05 MHz band has an operation that will cease by 1 January 1997. The IRAC's RCS also includes this band as a preliminary WRC95 proposals for NVNG MSS. The other, the 137138 MHz band is used in the U.S. by NOAA and DoD for MetSats operations. However, Congress has mandated that those entities consolidate their MetSat programs. This convergence of programs is still under discussion. Consequently, the time frame during which MetSats might migrate from this band is as yet uncertain. Discussions with NTIA on the eventual availability of this band continue. We invite further comment on including this band as a FCC proposal for a NVNG MSS allocation at WRC95.

Compared to other estimates, the Inmarsatbased forecasts are revised downward. This is because Inmarsat factored in a potential overlap in providing land mobilesatellite services (LMSS) between GSO and NGSO MSS networks. Nevertheless, a considerable amount of spectrum for GSO MSS will be required.

However, these bands are part of the transfer of spectrum from Federal use to private sector use and  N-are under consideration in our Spectrum Transfer Notice as candidate bands for mobile and fixed services. They are not likely candidates for U.S. proposals for MSS allocations. In particular, the 23002310 MHz band is being given to nongovernment use on an accelerated basis, but only for nonspace, nonairborne services. With regard to the 23902400 MHz band,  Na-in its preliminary report on identification of spectrum for private sector use the Department of Commerce expressed concern over the possible effect of private sector use on the National Astronomy and Ionospheric Center that conducts planetary research at 2380 MHz. To protect those operations the Department of Commerce stipulates that this band should not be  N -used for airborne or spacetoEarth links. See Spectrum Transfer Notice at paras. 56.

These adjustments reflect the Commission's allocation of the 18501990  R-MHz band for Personal Communication Services (PCS),d N4-#&Q2PQF&P#э See id. This decision likely precludes use of the 19701990 MHz band for coprimary MSS. and its effect on our ability to use that spectrum for MSS in the United States. Specifically, WARC92 made a secondary allocation for MSS in the 19301970 MHz band for Region 2 only. We are proposing to eliminate this allocation in the 19301945 MHz portion of this band. WARC92 also made a primary allocation for MSS in the 19701980 MHz band for Region 2 only. We are proposing to drop the status of MSS in this band to secondary. This would reflect the current PCS use in the U.S. but could allow some MSS operation. Finally, we propose to eliminate the primary MSS allocation in the 19801985 MHz band in all three Regions. This last proposal leaves a 5 MHz primary MSS overlap with the our domestic PCS allocation. Although this spectrum may not  R -be useable for primary MSS in the U.S.,!e @ N-#&d2PG;F&P#э Our proposals in this proceeding reflect our desire to obtain common, useable worldwide MSS allocations at 2 GHz. We note however, that at least one U.S. petitioner (CELSAT, Inc.; RM7927) has indicated that it desires to implement a hybrid PCS/MSS network that would use PCS spectrum on a coprimary basis. As there are differing, evolving requirements for access to 2 GHz spectrum for both terrestrial and MSS networks, parties should take these into account.! it may be useable in other parts of Region 2 and it provides additional spectrum for coordinating spectrum use between administrations international MSS networks. We invite comment on this proposed MSS allocation structure.  Rb-6. Date of Entry Into Force of MSS Spectrum Allocations Around 2 GHz.  R4->63.` ` At WARC92, different dates of entry into force (dates of entry) of 2 GHz MSS allocations were agreed upon. Footnote RR 746C specifies a date of entry of 1 January 1996 onwards for the United States, whereas RR 746B specifies a date of entry of 1 January 2005. In Task Group 8 /3, it was noted that, with new interest in implementing 2 GHz MSS systems on the part of administrations other than the United States, this difference in dates of entry could have an adverse impact on implementing  R-nonU.S. MSS networks.f`  Ns"-#&Q2PQF&P#э See ITUR Document 83/TEMP/36 (Rev.3), Geneva, 1994. This relates to the fact that MSS systems can only be notified 6 years in advance of the date of entry of an allocation. Many administrations have advance published 2 GHz MSS systems in advance of that timeframe and thus have been given unfavorable findings by the BR.  "|$@ f0*((m"Ԍ R-?64.` ` Parties take positions on both sides of the date of entry issue. Motorola opposes advancing the date of entry. Motorola argues that the U.S. should not support advancing the date of entry, because that action would be inconsistent with the use of 2 GHz spectrum for Future Public Land Mobile Telecommunication Systems  R-(FPLMTS)compatible satellite systems.g` N-#&Q2PQF&P#э RR 746A (WARC92) states in part: "The frequency bands 18852025 MHz and 21102200 MHz are intended for use, on a worldwide basis, by administrations wishing to implement the future public land mobile telecommunications systems (FPLMTS). Such use does not preclude the use of these bands by other services to which the bands are allocated." Motorola states that it would support moving the U.S. date in RR 746C to 1 January 2005 so that all potential MSS  Rv-operators would face identical constraints.jhv N -#&Q2PQF&P#э Motorola comments at 67.j  RH-@65.` ` COMSAT Mobile Communications (COMSAT) argues that the U.S. should propose moving the RR 746B date of entry forward to be compatible with the U.S. date (19962000). COMSAT contends that there will likely be early saturation of MSS bands, therefore, it is urgent that WRC95 provide access to 2 GHz bands  R -around the year 2000.ii  N--#&Q2PQF&P#э COMSAT comments at 712.i COMSAT also maintains that early access to 2 GHz spectrum would facilitate provision of a FLMPTScompatible satellite component worldwide.  R-A66.` ` The Commission's IAC recommends that the United States propose no change to its RR 746C date. It takes no position on advancing the RR 746B date. However, it does recommend that the U.S. adopt a position supporting a transition plan to gradually introduce MSS into 2 GHz bands sometime prior to the year 2005.  R-B67.` ` We note that although the current 1996 U.S. date of entry of RR 746C affords the United States maximum flexibility in implementing U.S.based MSS networks, advancing the 2005 date of RR 746B could facilitate early introduction of global MSS networks including future networks in which U.S. entities may have interests. Therefore, we believe that consideration of the differing dates of entry into force of 2 GHz MSS allocations should be in the context of an overall approach to making available 2 GHz MSS spectrum, including potential expansion of existing allocations as proposed elsewhere in this document. Therefore, we will not make a specific proposal at this time.  PN- " %0i0*((-"  P-B.Other WRC95 Issues  R-1. Space Services  R-C68.` ` Earth Stations in the 20252110 MHz Band.

Rv-3. High Frequency Broadcasting  RH-R83.` ` WRC95 Agenda Item 3c addresses the availability of High Frequency Broadcasting (HFBC) bands allocated at WARC79 and WARC92. The use of these bands was conditioned on the development of an acceptable worldwide planning system which has proven to be a difficult task due to excessive demand and limited  R -HFBC spectrum. Since the Notice, the ITU has established Task Group 10/5 for the purpose of addressing planning procedures.  R -S84.` ` Task Group 10/5 has made significant progress. In its draft report, the group examines planning procedures associated with broadcasting and other radio  Ry-services.xy N-#&Q2PQF&P#э ITUR Document 105/TEMP/5, 1994 (Report to CPM95). It enumerates guiding principles for a new planning procedure and describes the procedure for a new, simple, and flexible process for planning the HFBC bands. This approach is premised on the concept of seasonal coordination carried out at the regional level. Coordination is based on an agreed upon technical evaluation of the incompatibilities in the proposed broadcasting schedules. This technical evaluation is based on existing ITUR Recommendations. This approach will be refined at subsequent meetings of Task Group 10/5 scheduled after WRC95. The direction  R-Task Group 10/5 takes appears to be consistent with U.S. interests.yh N-#&Q2PQF&P#э We note, however, that during recent Task Group 10/5 meetings, representatives of the Asian Broadcasting Union (ABU) and Japan expressed strong interest in global coordination meetings hosted by the ITU. At present, these entities do not participate in the coordination meetings where European and North American entities coordinate their frequency use and thus they find that their interests do not at present have an adequate forum for consideration. Although the WRC95 agenda does not provide for substantive action on this issue, Task Group R-10/5's final report will likely be the basis for substantive action at WRC97.z`@ N!-#&Q2PQF&P#э Task Group 10/5 also concluded that a suitable planning procedure for HF broadcasting will be produced and provided to WRC97. Further, it recommends to WRC95 that it hold in abeyance its review of the VGE Final Report's proposed revision of Article 17  N#$-(Article S12) until WRC97. We request comments on these subjects. Į We invite further comment on the work of Task Group 10/5 and alternate approaches to facilitating the availability of HFBC bands.

Under the current WARC92 constraints, only Single Side Band (SSB) transmissions can be used in this additional spectrum. This matter may be linked to the approval of a planning procedure at WRC97. At present, SSB receivers are not widely available and represent a very small fraction of the HF receiver market. Also, the SSB receivers that are available are prohibitively expensive in many areas of the world. Commenters indicate that with the advent of new technologies, such as digital audio broadcasting (DAB), it may be unwise to impose a SSB standard without first giving further consideration to better long term alternatives. We request comments on the requirement of SSB transmissions in the new HFBC bands.  R -4.

This convergence, as well as the potential convergence with similar European meteorological satellite programs, is in the planning stage and the characteristics and"$L0*%%JJs#+" frequencies of operation of new satellites are not defined. Consequently, the time frame for migrating meteorological satellites from the 137137.025 MHz and 137.175137.825 MHz band is still under discussion.

ITUR Task Group 44 was formed to perform the necessary studies. This Task Group completed its studies and confirmed the values given in No. 855A. Recommendation ITUR S.1068 was developed with respect to the sharing of the fixedsatellite service with the radiolocation and radionavigation services. Resolves 2 of Resolution 112 called for studies with respect to the technical compatibility between the primary allocation to the fixedsatellite service (Earthtospace) and the secondary allocations to the space research and Earth explorationsatellite services. ITUR Task group 73 was established to study this compatibility taking into account the time frames given in No. 855B. Task Group 73 developed protection criteria for the secondary services. Task Group 44 considered constraints which would apply to the fixedsatellite service to meet these protection criteria within the time frames given in No. 855B. The two Task Groups, in close consultation, developed two companion Recommendations: ITUR S.1069 and ITUR SA.1071. These Recommendations provide further technical details with respect to the compatibility between the fixedsatellite services and these secondary services.
