Systemer, der leverer mobilkommunikationstjenester om bord på skibe (»MCV-tjenester«), har til formål at supplere den eksisterende mobilnetdækning i de områder af EU-medlemsstaternes søterritorier, jf. De Forenede Nationers havretskonvention, der ikke er dækket af landbaserede mobilnet, som er omfattet af Kommissionens beslutning 2009/766/EF af 16. oktober 2009 om harmonisering af 900 MHz-båndet og 1800 MHz-båndet for landbaserede systemer, som kan levere fælleseuropæiske elektroniske kommunikationstjenester i Fællesskabet [3].
Systems providing mobile communication services on board vessels (‘MCV services’) aim to complement existing mobile connectivity when operating in those areas of the territorial seas of the European Union Member States, as defined in the United Nations Convention on the Law of the Sea, that are not covered by land-based mobile networks, which are subject to Commission Decision 2009/766/EC of 16 October 2009 on the harmonisation of the 900 MHz and 1800 MHz frequency bands for terrestrial systems capable of providing pan-European electronic communications service in the Community [3].
