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

[edit]

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

Frequency allocation

[edit]

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).


 Frequency range       415... 495   kHz      505...526,5  kHz     1606,5...1625 kHz     1635...1800   kHz     2045...2160   kHz     2170...2173,5 kHz     2190,5...2194 kHz     2625...2650   kHz     4000...4438   kHz     6200...6525   kHz     8100...8815   kHz    12230...13200  kHz    16360...17410  kHz    18780...18900  kHz    19680...19800  kHz    22000...22855  kHz    25070...25210  kHz    26100...26175  kHz
