WRC-15 agenda items 1.3 and 1.4

Broadband PPDRConclusion* towards possible additional RF spectrum in some countries, either

listed in Res. 646 (Rev. WRC-15) or listed in non-mandatory ITU-R Rec.

Common RF spectrum would ease coordination and harmonization

Amateur Radio for emergencyConclusion* towards a possible new 2ndary

allocation to amateur service, if any, within the frequency range 5 275 – 5 450 kHz

* See CPM Report to WRC-15


WRC-15 agenda items 1.11 and 1.12

Earth observation-SatelliteConclusion* towards a possible new primary

allocation to the EESS, if any, to accommodate spectrum requirements between 38 and 56 MHzin the band 7 190-7 250 MHz, with different conditions establishing protection of currently allocated services

Conclusion* towards a possible extension of the current

EESS (active) allocation at 9.3-9.9 GHz by up to 600 MHz only for use by future high-resolution radars (SAR) (50cm) within the band(s):

- 9 900-10 500 MHz (Primary), or- 9 200-9 300 MHz and 9 900-10 400 MHz (Primary) or- 9 200-9 300 MHz, 10 000-10 100 MHz (Primary) and

9 900-10 000 MHz (Secondary) or- No change


APG15-5/INF-22

Page 18 of 26

19



Space Research

Conclusion* towards a single solution:

Remove the 5 km distance limitation for proximity operations by space vehicles communication with orbiting manned space vehicle, and not solely limit the use of the 410-420 MHz band by SRS (s-to-s) for extra-vehicular activities




Feasibility of achieving a continuous reference time-scale, conclusion* towards 4 possible options:

UTC and leap seconds

Remove the leap second insertion or deletion from the UTC definition => contiguous time scale (retain UTC name or adopt a new name)

Keep current UTC definition and disseminate both theUTC time-scale & a continuous time-scale on an equal basis;

Keep current UTC definition but enable the recovery of the International Atomic Time (TAI) from the current implementation of UTC or use a continuous system time-scale.

No change to the RR as results of studies are inconclusive* See CPM Report to WRC-15

Aeronautical Issue #1 (UAS in FSS)

Unmanned Aircraft Systems – Consider use of FSS bands (not App. 30/30A/30B) for control and non-payload communications (CNPC) of UAS in non-segregated airspaces.Different views were added on the analysis of the results of studies.Conclusion* towards 2 possible solutions:

Identify conditions under which systems operating in the FSS could provide UA CNPC links;

No change, on the basis of concerns about the ability of FSS to provide a safety service.




Spectrum requirements & regulatory actions, including appropriate aeronautical allocations, to support Wireless Avionics Intra-Communications (WAIC)

Aeronautical Issue #2 (WAIC)

Conclusion* towards a new Primary allocation to the AM(R)S reserved exclusively for WAIC systems in the frequency band 4 200-4 400 MHz

GFT on WRC-15 agenda

Aeronautical Issue #3(Global flight tracking for civil aviation)

(PP-14) resolves to instruct WRC-15, pursuant to No. 119 of the ITU Convention;

to include in its agenda, as a matter of urgency, the consideration of global flight tracking, including, if appropriate, and consistent with ITU practices, various aspects of the matter, taking into account ITU-R studies,

instructs the Secretary-General

to bring this resolution to the attention of WRC-15 and ICAO,

instructs the Director of the Radiocommunication Bureau

to prepare a specific report on the matter as referred to in resolves above for consideration by WRC-15.

ITU-R studies on-going within Working Parties 5B & 4C

Two views included in Annex 1 of the CPM Report to WRC-15



Conclusion* towards a Primary allocation to the RLS in frequency band 77.5-78 GHz on a worldwide basis either:

limited to automotive applications (with short range high resolution radars), OR

supporting automotive radar operations

Automotive Radar Applications


APG15-5/INF-22

Page 21 of 26

22



Conclusion* towards a more efficient use of the existing frequencies in the range 450-470 MHz with the introduction of the possibility to use digital modulation and improved mitigation techniques.

Maritime Issue #1 (on board communication)




Maritime Issues #2 (Automatic Identification System)

Regulatory provisions & spectrum allocations to enable possible new Automatic Identification System (AIS) technology and other new applications to improve maritime radiocommunication

Conclusion* towards different solutions with the goal to introduce a new concept called VHF data exchange system (VDES) with terrestrial and satellite components.

Satellite FSS allocation IssuesAI 1.6.1: … 250 MHz, both directions, 10-17 GHz range, Reg.1AI 1.6.2: … Earth-to-space direction, 250 MHz in Reg. 2 and

300 MHz in Reg. 3, within the range 13-17 GHz

Conclusions* towards possible new allocations in the ranges highlighted above, with appropriate conditions of use such as PSD limits, E/S antenna minimum diameter, coordination distances, etc., according to the case




Use of 5091-5150 MHz by FSS (E-s), limited to feeder links for N-GSO MSS systems

Conclusions* towards maintaining this primary allocation withi) SUP of the time limits in RR No. 5.444A; ii) Conditions of use in a revision of Res. 114 (e.g. coordination of FSS E/S with ARNS ground stations)

WRC-15 agenda item 1.8Review the provisions relating to earth

stations located on board vessels (ESVs)Different possible conclusions* towards:A) No change of the current situation; orB) Increasing off-shore protection distance in

the C band (> 300 Km); orC) Establishment of different protection distances for

different maximum e.i.r.p. density levels, with shorter protection distances for e.i.r.p. density levels lower than those currently allowed by Resolution 902 (WRC-03); or

D) Establishment of different protection distances for different maximum e.i.r.p. density levels accounting for the statistical information on maritime traffic and the probability of frequency overlapping; or

E) Review of the regulatory regime governing ESVs operation* See CPM Report to WRC-15


WRC-15 agenda item 1.9.1
