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
WRC‐15 Agenda Item 1.16
• 1.16
to consider regulatory provisions and spectrum allocations to enable possible new Automatic Identification System (AIS)
technology applications and possible new applications to improve maritime
radiocommunication in accordance with Resolution
360 (WRC-12);
WRC‐12 Resolution 360
WRC‐12 Resolution 360 Resolves to invite WRC‐15
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.

NOTE – The VHF channels shown above are a contiguous set in RR
Appendix 18. They comprise a
contiguous frequency block, and thus are
amenable to protection by a single selective filter in the receiver.

Future Maritime Agenda Items for WRC‐18
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.
