    Socio-economic benefits of harmonisation of the S-band CGC in Europe 6 November 2015 Executive summary In 2009 two satellite operators --Solaris Mobile Limited, now EchoStar Mobile Limited (EML), and Inmarsat -- were granted licences to operate an S-band mobile satellite service (MSS) in combination with a Complementary Ground Component (CGC) throughout the European Union (EU). Both companies have excellent track records in the commercialisation of innovative services based on satellite technology and next year both intend to launch new satellites to deliver the MSS component throughout Europe. Inmarsat intends to offer a range of aviation services while EML intends to offer MSS, CGC and hybrid services throughout Europe on a wholesale basis through partnerships with regional and local operators. Potential services that could be offered by EML’s partners include machine-to-machine (M2M) communications, public protection and disaster relief (PPDR) services, mobile broadband, support for private networks and mobile virtual network operators (MVNOs) and lower cost mobile satellite services. The EU S-band regime was intended to give the S band licensees the means to offer advanced voice and data services throughout Europe using both the MSS and the CGC to avoid the service gaps typically associated with either a stand-alone MSS or terrestrial service. However, the ability of EML to press ahead and launch the full range of the commercial services that were envisaged by the EU, including those that rely on the CGC, is constrained by the fact that some member states have not yet implemented the rules or created a licensing regime for the S-band CGC while others are proposing to adopt a narrow interpretation of EU rules – specifying, for example, that the CGC must carry the same traffic as the MSS (effectively forcing the CGC to be used as an MSS repeater only).
