3 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

4 WRC 15 Agenda Item 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);

6 WRC 12 Resolution 360 Resolves to invite WRC 15

7 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

8 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.

9 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.

11 Regional VHF Data Exchange Channels (Proposed) Regional VDE (Regions 1 and 3) Ship transmit Ship receive Can be used separately and/or as 50 khz channel(s) or as one 100 khz channel Can be used separately or as one 50 khz channel 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.

12 ITU R Working Party 5B Agenda Item 1.16 Work Plan WP 5B 13 th meeting May Further work on sharing studies and compatibility. 2. Finalization on the list of candidate frequencies for VDES 3. Progress on the development of the relevant ITU R Report and Recommendation for the VDES. 4. Establish the Regulatory measures needed, taking into account the current proposal for the VDES 5. Finalization of the draft CPM Report. WP 5B 14 th meeting November 2014 WP 5B 15 th meeting May 2015 Finalization of all studies quoted to the draft CPM Report for WRC Finalization of the ITU R Report on the AIS requirements and on the new additional requirements of maritime mobile service.

13 CPM VDES Timeline

14 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

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.
