World Radio Conference (WRC‐12) Results

– Exclusive Utilisation of AIS 1 and AIS 2 by the  maritime mobile service in Region 2 and 3 (in 2025)

– Allocation for the mobile satellite service for the  channel 75 and 76 in order to detect the Message 

27 of AIS for the Long Range AIS

– Identification of the channels 27, 28, 87, 88 for

testing  future AIS applications, e.g. Application Specific 

Messages (ASM)

– Identification worldwide of channels 24, 84, 25, 85,  26, 86 for utilization of digital systems

ITU‐R Working Party 5B 

VHF Data Exchange System (VDES)• Significant support internationally at ITU, IMO and IALA 

to protect the AIS VDL and as a VHF Data solution • Concept includes:

– AIS 1 and 2 (Navigation – as originally intended)– AIS 3 and 4 (Satellite – space detection of AIS)– ASM 1 and 2 (Application Specific Messages, MSI)– VHF Data (General Data Comms) Channels 24, 84, 25,

85, 26, 86)

*Potential for future Distress capabilities

ITU‐R WP5B Agenda Item 1.6 CPM  Text Development

• In November 2013 the frequency/channel  arrangement remain under discussion and has to 

be reedited after agreement. • There are three channelling plans for VDES under 

studies. • The only agreement is that the VDES terrestrial 

and satellite component will be deployed in the  following channels: 24, 84, 25, 85 26, 86. 

• Ship and Shore transmit arrangements and the  transition period  have to be decided.

CPM TEXT METHODS

• METHOD A: After the transitional period  [1

January

2019], RR Appendix 18

CH27 and CH28 will 

be split into four simplex channels, CH1027, CH1028,  CH2027 and CH2028. CH2027 and CH2028 will be 

assigned for the ASM application.

• METHOD B: Channel 87 and 88 could be used as ASM  channels with an effective date TBD.

• METHOD C:

CH2027 and CH2028 will be assigned for  the ASM application with an effective date TBD.

WRC‐12 Resolution 359 ‐

Consideration of regulatory  provisions for modernization of the Global Maritime 

Distress and Safety System and studies related to e‐ navigation. Resolves

1.

to invite WRC‐18 to consider possible regulatory  actions, including spectrum allocations based on the 

ITU‐R studies, to support GMDSS modernization;2.  to consider possible regulatory actions, including 

spectrum allocations based on the ITU‐R studies, for  maritime mobile service supporting e‐navigation

*Subject to change at WRC‐15

WRC‐15 and WRC‐18 Maritime Opportunities 

• The Maritime community has a great  opportunity to secure additional channels to 

protect the VDL and to develop a  comprehensive terrestrial and satellite system 

that will significantly enhance AIS and VHF  communications.

• Additionally, opportunities exist to enhance  Polar communications, modernize the GMDSS, 

and satisfy e‐Navigation requirements.
