Agenda item1.1: to consider additional spectrum allocations to the mobile service on a primary basis and identification of additional frequency bands for International Mobile Telecommunications (IMT) and related regulatory provisions, to facilitate the development of terrestrial mobile broadband applications, in accordance with Resolution 233 (WRC-12);

1. FREQUENCY RANGES BELOW 1 GHz

1.1 BAND 410-430 MHz

BACKGROUND:

WRC-15 will consider additional allocations to the mobile service on a primary basis and identification of additional frequency bands for IMT in accordance with Resolution 233 (WRC-12).

Article 5 allocates the 410-430 MHz frequency range to the mobile (except aeronautical mobile) service on a primary basis. However, these bands are not identified for IMT. Some Administrations introduced Preliminary Views supporting consideration of identifying the 410-430 MHz frequency range for IMT. Thus far no new ITU-R studies have been initiated to show compatibility between IMT and incumbent services in this frequency range since the adoption of Report ITU-R M.2110.which only addressed the 420-450 MHz frequency range in terms ofadjacent band compatibility.

No. 5.269 allocates the420-430 MHz and 440-450 MHz bands to the radiolocation service on a primary basis in specified countries. Article 5 allocates the 430-440 MHz bands to the radiolocation service on a primary basis worldwide. The 420-450 MHz bands are used in some countries for high-powered radars that detect and track earth-orbiting satellites and space debris. These radars also aid in identifying potential space debris hazards that could damage the International Space Station.

Report ITU-R M. 2110 accessed the feasibility of sharing between an IMT-2000 system operating in the 450-470 MHz band and the radiocommunication services having a primary allocation in Article 5 of the Radio Regulations in the 450-470 MHz band and in the adjacent 420-450 MHz and 470-480 MHz bands. The results indicate that for most cases, sharing between IMT-2000 base/mobile stations and the various types of radars when placed in adjacent spectrum is not feasible in the absence of mitigation. Based upon Report ITU-R M.2110, it is logical to conclude that co-frequency sharing between IMT and the radiolocation service in the 420-450 MHz bands is not feasible.

This proposal advocates no change to Article 5 Table of Frequency Allocations for the bands 420-450 MHz.

2. FREQUENCY RANGES BETWEEN 1-2 GHz

1.1 BAND 1350-1400518 MHz

BACKGROUND:

The Brazilian Administration conducted studies to satisfy agenda item 1.1 in various bands and concluded that the L-band should be used for mobile broadband. Specifically, Brazil is of the view that the bands 1350-1400 MHz, and 1427-1518 MHz should be considered as possible candidate bands for IMT identification at WRC-15.

Portions of the spectrum in the 1350-1518 MHz band (except for the 1400 MHz-1427 MHz band) are not extensively used in Brazil, as well as in most countries in Region 2. Although the band is allocated for radiolocation, broadcasting and broadcasting-satellite services in Region 2, many countries such as Brazil, Colombia and Mexico are looking into the actual usage of the L-band and are coming to the conclusion that the band is underused, and that the use of the band by the services mentioned above is not foreseen to increase in any significant manner in the near future.

Brazil aims to encourage the countries of Region 2 to change this situation and consider allowing that 141 MHz of spectrum to be used for new mobile services and applications with the aim of bringing substantial social and economic benefits to the region.

Other regions have already begun to examine this band for use by IMT. Some administrations in Europe, for example, are looking into the possibility of using parts of the L-band, for example 1375-1400 MHz paired with 1427-1452 MHz, for IMT, which could allow for frequency division duplex (FDD) services.1 In addition, the 1452 MHz to 1492 MHz frequency range at the L-band is now being harmonized for Supplemental Downlink (SDL) mobile applications by the European Conference of Postal and Telecommunications Administrations (CEPT).2 At the 35th ECC meeting of the Electronic Communications Committee (ECC) of CEPT, in November 2013, a decision was approved on the “harmonized use of the frequency band 1452-1492 MHz for Mobile/Fixed Communications Network Supplemental Downlink (MFCN SDL)” resolving that the CEPT administrations should designate the frequency band 1452-1492 MHz to SDL.3 This decision was approved with great support from the administrations, with 25 administrations indicating that they will implement the ECC Decision.

PROPOSAL:

Based on its analysis of the current situation, the Brazilian Administration proposes that the 1350-1400 MHz band be allocated to the mobile service on a primary basis and that the 1350-1400 MHz and 1427-1518 MHz bands be identified for use by IMT, in response to agenda item 1.1. Proposed changes to the Table of Allocations are shown below.

This identification does not preclude the use of these bands by any application of the services to which they are allocated and does not establish priority in the Radio Regulations.

Reasons: The identification of parts of the L-band to IMT will help satisfy agenda item 1.1.

2.21.2 BANDS 1435-1525 MHz y 1525-1535 MHz

BACKGROUND:

The band 1435 MHz – 1525 MHz (and subsets of the band) have been identified as “suitable frequency ranges” for IMT; they have also been addressed in sharing studies conducted within Joint Task Group JTG 4-5-6-7 in preparation for the 2015 World Radio Conference. The band has been and continues to be used widely in the United States and other Region 2 Administrations for aeronautical mobile telemetry (i.e. “AMT,” or “flight test”).

The 1435 – 1525 MHz band is essential for aerospace research and development, and for the certification of aircraft prior to commercial use. Interference-free, real-time use of the band is essential to the protection of test aircraft, payloads, flight crews, and persons and property located beneath flight test airspace. The continued use of the band 1435 - 1525 MHz on an interference-free basis is essential for the aerospace manufacturing industries and their many suppliers in Region 2, including Administrations in both North and South America.

Based on the studies introduced to date in the JTG, AMT sharing of the band with interference- limited

IMT services has been demonstrated as infeasible.4 The studies concluded independently that co-frequency operation of AMT and IMT operations requires exclusion zones in excess of100 km with respect to interference from IMT to AMT ground stations, and over 350 km for interference from AMT aircraft to IMT systems on the ground. The latter distance is measured with respect to the flight test ground station that is supervising the flight test aircraft. Flight test aircraft routinely fly several hundred kilometers in all directions from their AMT ground stations. This extends the impact of signals from aircraft transmitters to IMT users to distances that are well beyond the radio line of sight from the IMT user to the AMT ground station.

4 See JTG 4-5-6-7/ Docs 156 (July 2013)and4-5-6-7/291 (October 2013)


Radio Regulation 5.343 prescribes that “In Region 2, the use of the band 1435-1535 MHz by the aeronautical mobile service for telemetry has priority over other uses by the mobile service.”

The United States proposes to retain this foot note in Region 2 in order to protect the flight safety aspects of AMT operations from domestic and cross-border interference.

RR 5.343 is important for the avoidance of cross-border interference to and from flight test operations in Region 2. The footnote does not preclude administrations from implementing any mobile service systems within their own territories; rather, it ensures that in sensitive border areas administrations take proper account of long-established AMT operations.

For the foregoing reasons, the 1435 – 1535 MHz band should not be identified for IMT use in Region 2.

2.3 BANDS 1 164-1 215 MHz, 1 215-1 300 MHz and 1 559-1 610 MHz

Background:

The bands 1 164-1 215 MHz, 1 215-1 300 MHz and 1 559-1 610 MHz, are actively used for radionavigation-satellite services (RNSS) in all three ITU Regions. RNSS signals, which are transmitted from RNSS satellite constellations, are very low-power and use spread-spectrum modulation techniques. Special processing is required of RNSS receivers to detect and extract these low power signals from the background noise. A high-power signal broadcasted in the same frequency range and in proximity to a RNSS receiver could desensitize this receiver, rendering it unable to extract the RNSS signal transmitted by the RNSS satellites.

Proposals:

An allocation to the mobile service and designation for IMT should not be considered for the bands 1 164-1 215 MHz, 1 215-1 300 MHz and 1 559-1 610 MHz due to the incompatibility of RNSS with mobile services.

1.4 BANDS 3 400 – 3 700 MHz

Background

The frequency range 3 400-4 200 MHz, or parts thereof, is allocated to the Fixed (FS), Fixed Satellite (FSS), Amateur Radio (ARS), Mobile (MS) and Radiolocation (RLS) services.

Specifically, in Region1, the FS and FSS (space-to-Earth) have a primary allocation, while the MS and RLS have a secondary allocation in the band 3 400-3 600 MHz. The FS and FSS have a co-primary allocation and the MS has a secondary allocation in the band 3 600-4 200 MHz.

In Regions 2 the FS and FSS have a co-primary allocation in the range 3 400-3 500 MHz band, while the ARS and RLS have secondary allocations. In the band 3 500-3 700, the FS, FSS and MS have co-primary allocations while the RLS has a secondary allocation. In the band 3 700-4 200 MHz, the FS, FSS and MS have a co-primary allocation.


In Region 3, the frequency band 3 400-3 500 MHz is allocated to the FS and FSS on a co-primary basis and to the ARS, MS and RLS on a secondary basis. In the band 3 500-3 600 MHz, the band is allocated to the FS, FSS and MS on a co-primary basis and the RLS on a secondary basis. The band 3 600-3 700 MHz is also allocated to the FS, FSS and MS on a co-primary basis and the RLS on a secondary basis. In the band 3 700-4 200 MHz, the FS, FSS and MS have a co-primary allocation.

At the World Radiocommunication Conference-2007 (WRC-07), the frequency band 3 400-3 600 MHz was identified for use by IMT systems in the countries indicated in footnotes 5.430A, 5.432A, 5.432B and 5.433A under specific conditions outlined in those footnotes.

It is noted that under footnote 5.431A “Different category of service: in Argentina, Brazil, Chile, Costa Rica, Cuba, French overseas departments and communities in Region 2, Dominican Republic, El Salvador, Guatemala, Mexico, Paraguay, Suriname, Uruguay and Venezuela, the band 3 400-3 500 MHz is allocated to the mobile, except aeronautical mobile, service on a primary basis, subject to agreement obtained under No. 9.21. Stations of the mobile service in the band 3 400-3 500 MHz shall not claim more protection from space stations than that provided in Table 21-4 of the Radio Regulations (Edition of 2004)”.

It is further noted that work with respect to sharing studies between IMT and other services/applications has concluded at the ITU-R JTG 4-5-6-7. These studies include in-band and adjacent band analysis of the compatibility and sharing feasibility between IMT and the FSS and FS. Analyses of the results for all the frequency bands studied are contained in the draft CPM text for WRC-15 agenda item 1.1 (see Annex 3 of Document 4-5-6-7/715). Canada recognizes that appropriate measures to address compatibility between MS and FSS systems are an important consideration that will be part of the discussion at WRC-15.

Although FSS operations in Canada are in the range 3 700-4 200 MHz, Canada recognizes that other administrations may have FSS and FS operations in various portions of the band 3 400-3 700 MHz.

Discussion

In Region 1, the CEPT supports identification for IMT in the bands 3 400-3 600 MHz and 3 600-3 800 MHz. In the APT, discussions are underway to consider various portions of the range 3 400-4 200 MHz for IMT identification and/or use.

The World Meteorological Organization (WMO) has indicated that the band 3 400-4 200 MHz is used to distribute meteorological data through commercial satellite systems.

Canada recognizes that 14 CITEL administrations have a mobile, except aeronautical mobile, service allocation on a primary basis in the frequency band 3 400-3 500 MHz via No. 5.431A. It also recognizes that some administrations have expressed interest in raising this mobile allocation from secondary to primary.

Reason: This footnote is modified as the primary mobile allocation would be available to all in Region 2 and as such the country list would no longer be required.

ADD CAN/1.1/3


5.xxx The frequency band 3 500-3 700 MHz is identified for use by administrations wishing to implement International Mobile Telecommunications (IMT). This identification does not preclude the use of these bands by any application of the services to which they are allocated and does not establish priority in the Radio Regulations.

Reason: Identification of the band 3 500-3 700 MHz for IMT to promote globally harmonized spectrum for IMT.

1.5 BAND 3500-4200 MHz

1. INTRODUCTION

Due to its geographic location, tropical weather prevails over much of the Republic of Guatemala, making it common to see the low atmospheric pressures of inter-tropic convergence areas. This results in continual, intense precipitation, especially throughout the second half of the year.

Therefore, despite the new frequency band options for satellite communications, the “C” band is still widely used. To ensure efficient operation of land stations linked to satellites transmitting on the “C” band, national footnotes GTM-23 and GTM-24 on the National Frequency Allocation Table define how the 3 500 – 4 200 MHz band is being used in Guatemala. Logically, this definition prioritizes and protects Fixed Satellite Service allocations in that band.

From this viewpoint, Guatemala believes that the band in question is an irreplaceable pillar of satellite communications, especially at times of the year when weather is bad.

2. PROPOSAL

Based on its National Frequency Allocation Table, Guatemala proposes that on the 3 500 – 4 200 MHz frequency band, no changes be made to the current deployment allocations shown on the Radio Regulations and that said band not be identified for IMT deployment. The detailed proposal is shown below.

Rationale: “C”-band satellite communications are an important part of the telecommunications infrastructure in Guatemala. The continuity of satellite communications in the country can be ensured by maintaining current “C”-band allocations and uses, and by managing satellite operation licensing without interference in terms of what the National Frequency Allocation Table calls the “C” band.

1.6 BAND 5000-5010 MHz and 5010-5030 MHz

Background Information: The 2012 World Radiocommunication Conference (WRC-12) recognized a need for additional radio spectrum to support the increasing mobile data traffic, and placed consideration of additional spectrum allocations for terrestrial mobile broadband applications on the Agenda for WRC-15. Joint Task Group (JTG) 4-5-6-7 considered spectrum requirements for IMT/terrestrial mobile broadband applications and developed sharing and compatibility studies, taking into account protection requirements of other services from concerned ITU-R Working Parties.

The radionavigation-satellite service (RNSS) has allocations for Earth-to-space operations in the 5 000-5 010 MHz band and space-to-Earth and space-to-space operations in the 5 010-5 030 MHz band. Operators plan to operate several global and regional non-geostationary satellite RNSS systems, including GPS, QZSS, and Galileo, within these bands. RNSS shares its allocations 5 000-5 010 MHz and 5 010-5 030 MHz with the aeronautical radionavigation service (ARNS), which is a safety service.

There is a long history of protecting RNSS operations in the ITU. Multiple RNSS systems and networks transmit signals around-the-clock across all three ITU Regions and radiate across the entire surface of the Earth. Although these RNSS allocations are in bands that have favorable propagation and other characteristics for terrestrial mobile broadband, the ITU did not study the use of these or adjacent bands.


Due to the vital and global role of the RNSS, the sensitive nature of RNSS receivers, and lack of relevant sharing and compatibility studies within the ITU-R, no allocation to the mobile service for IMT, or identification for IMT, should be considered in the bands 5 000-5 010 MHz or 5 010-5 030 MHz.

1.7 BAND 5350-5470 MHz

BackgroundStudies indicate that sharing between EESS (active) and RLANs in the band 5 350-5 470 MHz may only be feasible if effective mitagtion measures are implemented. In that regard, additional studies were submitted to the ITU-R to examine possible mitigation measures, such as dynamic frequency selection, database look up and other measures, to address potential sharing between EESS (active) and RLANs. At this time, no effective mitigation measures have been identified. It is also noted that the draft CPM text contains only a single method of no change NOC to satisfy the agenda item for the frequency band 5 350-5 470 MHz.
