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.
Thank You!
