Utilization of the 495-505 kHz band by the maritime mobile service for the digital broadcasting of safety and security related information from shore-to-ships
This Report describes a technical approach allowing the reuse of the 500 kHz band for digital broadcasting of maritime safety and security related information for the benefit of ships at sea. Systems based on this technical approach can coexist with the worldwide NAVTEX system that operates on 490 kHz, 518 kHz, and in some cases 424 kHz.
