Global VSAT Forum (“GVF”)InformationPaper onWRC-15AgendaItem 1.1
The WorldRadiocommunication Conference2012(“WRC-12”) decided in itsResolution 807 torecommendto the Councilthe agenda for the World Radiocommunication Conference2015
(“WRC-15”), which includesan item (Agenda item 1.1)“toconsideradditionalspectrumallocationsto themobileserviceona primarybasisand identification ofadditionalfrequencybandsforInternationalMobileTelecommunications(IMT)and relatedregulatoryprovisions, to facilitatethedevelopmentofterrestrialmobilebroadband applications,in accordance withResolution233(WRC-12)”.1
The firstsessionof the ConferencePreparatoryMeeting for WRC-15 (“CPM15-1”) decidedtoestablish a Joint Task Group among Study Groups4,5, 6and7 (“JTG4-5-6-7”)asresponsible forconductingtherelevantstudies in accordancewiththeTermsof Reference specified in Annex10ofthe Administrative CircularCA/201.2ITU-RWorkingParty 5D (“WP 5D”)istaskedwith determining“suitable frequency ranges”forInternationalMobile Telecommunications (“IMT”) systems. WP5Dis continuing towork onthe identification of“suitable frequency bands”.Atpresent, a largenumberof frequencybands havebeen identified, totalling 3,765 MHz below6 GHz.Thesefrequencybands are in addition tothe totalof1,177MHz which havealready been identified forIMTinthe RadioRegulations, and the738.5MHzwhich are available forRadioLocal Area Networks(“RLANs”).Some frequencybands above6 GHz havealso been suggested by WP 5D, these bandstotalling an additional5,100 MHzof spectrum.Inall,more than10,000MHzof spectrumhasbeensuggested aspotentiallysuitableforusebyIMTsystems.
Severalofthe identified bandsfor IMT systemsareallocated tosatelliteapplications, and are eithercurrently usedor areplanned for use by satelliteapplications.Thefrequencybands of particularconcernto theglobal satellite community arethefollowing: 1,452-1,492 MHz
This documentexamines the potential foroperationof IMT systemsinsomeofthesefrequencybands. In particular, this document provides detaileddiscussionon theL-band geostationarymobile-satellite service(“GSO MSS”) bands and the C-band fixed-satellite service(“FSS”)bands,whicharewidely used by satelliteapplications andforwhichthere currentlyappears tobeinterestfor terrestrial IMT applications.3
