Executive summary As the Internet traffic grows, Broadband satellite systems have to increase their capacity. Beyond space segment performance upgrade, additi
24、onal spectrum is needed. Ka band is the preferred frequency band for such network. It includes exclusive spectrum allocation to FSS as well as spectrum shared between FSS and other services among which FS or FSS feeder links for BSS. Until now, the risk associated to the use of these shared bands ma
25、y have discouraged its full exploitation by satellite systems. Cognitive radio techniques may help to minimize this risk under appropriate operational and regulatory conditions. The present document provides an overview of typical Broadband Satellite systems targeting the Ka band shared between FSS
26、and other services, the related market data and spectrum regulation context. It then analyses the co-existence scenarios of FSS with FS or FSS feeder links for BSS, the enabling Cognitive Radio techniques as well as operational and regulatory conditions for a safer use of the shared spectrum. Introd
27、uction The present document has been developed to support the co-operation between ETSI and the Electronic Communications Committee (ECC) of the European Conference of Post and Telecommunications Administrations (CEPT). Flexible spectrum utilization is a surging trend for the optimized exploitation
28、of spectrum resources, and the cognitive approach has already demonstrated its potential for terrestrial systems, but not yet in the SatCom domain. However, SatCom are fundamental to achieve the challenging objectives of fast broadband access for everyone by 2020: their inherent large coverage footp
29、rint makes them the most suitable access scheme to reach those areas where deployment of wired and wireless networks is not economically viable. The Cognitive Radio (CR) paradigm has been identified as a promising solution to conciliate the existing conflicts between spectrum demand growth and spect
30、rum under utilization, and increase the overall efficiency of spectrum exploitation. ETSI ETSI TR 103 263 V1.2.1 (2016-02) 6 It is worth mentioning the 03-September-2012 Communication (2012) 478 i.8 from the European Commission to the European Parliament, the Council, the European Economic and Socia
31、l Committee and the Committee of the Regions on the promotion of the shared use of radio spectrum resources in the internal market. This communication provides clear guidance on the ways the technology research can help the compliance of the policy objectives. Furthermore, in 2011, the Radio Spectru
32、m Policy Group (European Commission) issued a Report on Collective Use of Spectrum that noted the high demand for shared use i.1. The RSPG stated that: “there is a need to progress further on appropriate regulatory mechanisms in regard to sharing of spectrum“. The key challenge for National Radio Au
33、thorities is to find appropriate ways to authorize shared spectrum access to a band, i.e. to allow two or more users to use the same frequency range under a defined sharing arrangement. This justifies the relevance of the present document that analyses the potential of CR concepts in satellite netwo
34、rks context, in order to improve coexistence scenarios in selected spectrum allocated to SatCom services. It has been largely drafted with the support of the EU funded project CoRaSat (see i.51). ETSI ETSI TR 103 263 V1.2.1 (2016-02) 7 1 Scope The present document identifies the potential regulatory
35、 impacts associated to the operation of SatCom solutions implementing cognitive radio techniques. In particular it addresses different scenarios in Ka band (17,3 GHz - 20,2 GHz for space to earth and 27,5 GHz - 30,0 GHz for earth to space) where the satellite communication service should not create
36、any harmful interference to another incumbent whether terrestrial or satellite service entitled to use the same spectrum on a primary basis. It includes in particular: market information; technical information (including expected sharing and compatibility issues); regulatory issues. The present docu
37、ment also identifies the existing related ETSI standards enabling this kind of architecture. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
