Extending mobile communications to the sea
Since 2016, through activities centered on 3GPP and IALA, we have researched the requirements for applying land-based mobile communications to the sea, including linking vessel identification with communications identifiers, maritime communication ranges of approximately 100 km, ship-to-ship communications and the delivery of maritime emergency information. In 2018, these requirements were incorporated into 3GPP international technical specifications.
Over the course of maritime standardization, we took part in 25 meetings and submitted 159 contributions, completing the technical specifications through review and validation with global mobile communications companies. This experience now underpins our research on communications for autonomous vessels, DX-Ocean and our maritime data services.
