RES362 – 311 – further recognizing a) that the majority of autonomous maritime radio devices using AIS technology are operating in AIS 1 and AIS 2 frequency bands, and, to some extent, occupying the resources of MMSIs for ship stations or aids to navigation; b) that Recommendations ITU-R M.493, ITU-R M.1371 and ITU-R M.541 describe technical and operational characteristics for some relevant maritime radio devices; c) that Report ITU-R M.2285 provides an overview of systems and their mode of operation for some maritime devices used as maritime survivor locating systems and devices (man overboard systems); d) that an evaluation of the effects on the functioning of AIS used for the safety of navigation, and especially search and rescue activities implemented by AIS-search and rescue transmitters (AIS-SARTs), is required, noting a) that WRC-12 designated channels in Appendix 18 of the Radio Regulations for experiments and testing for the future new AIS applications or systems; b) that ITU-R has been requested to study a future new maritime identification scheme, resolves to invite the 2019 World Radiocommunication Conference to consider the results of ITU-R studies and take appropriate actions, invites ITU-R 1 to conduct the necessary studies in time for WRC-19 to determine the spectrum needs and technical and operational characteristics of autonomous maritime radio devices operating in the frequency band 156-162.05 MHz; 2 to conduct the necessary studies to categorize the various autonomous maritime radio devices; 3 to conduct sharing and compatibility studies, based on the results of invites ITU-R 1 and 2, to ensure that no undue constraints are placed on the GMDSS and AIS; 4 to conduct studies, taking into account the results of invites ITU-R 1 to 3, and existing maritime technology, to determine potential regulatory actions and appropriate frequencies for autonomous maritime radio devices within the frequency band 156-162.05 MHz,
