Maritime mobile service

A maritime mobile service (also MMS or maritime mobile radiocommunication service) is a mobile service between coast stations and ship stations, or between ship stations, or between associated on-board communication stations. The service may also be used by survival craft stations and emergency position-indicating radiobeacon stations.^[1]

Classification

This radiocommunication service is classified in accordance with ITU Radio Regulations (article 1) as follows:

Maritime mobile service
- Maritime mobile-satellite service (article 1.29)
- Port operations service (article 1.30)
- Ship movement service (article 1.31)

Frequency allocation

The allocation of radio frequencies is provided according to Article 5 of the ITU Radio Regulations (edition 2012).^[2]

In order to improve harmonisation in spectrum utilisation, the majority of service-allocations stipulated in this document were incorporated in national Tables of Frequency Allocations and Utilisations which is with-in the responsibility of the appropriate national administration. The allocation might be primary, secondary, exclusive, and shared.

primary allocation: is indicated by writing in capital letters (see example below)
secondary allocation: is indicated by small letters
exclusive or shared utilization: is within the responsibility of administrations

However, military usage, in bands where there is civil usage, will be in accordance with the ITU Radio Regulations. In NATO countries military utilizations will be in accordance with the NATO Joint Civil/Military Frequency Agreement (NJFA).
