WRC 2019 Agenda Items for WP 1B

This agenda item considers, based on the results of ITU-R studies: regulatory actions within the frequency band 156-162.05 MHz for autonomous maritime radio devices to protect the GMDSS and automatic identifications system (AIS), in accordance with Resolution 362 [COM6/10] (WRC-15).

This includes:

1. studies into the spectrum needs and technical and operational characteristics of autonomous maritime radio devices,
2. to conduct studies to categorize the various device types,
3. to conduct sharing and compatibility studies to ensure that no undue constraints are placed on the GMDSS and AIS and
4. from 1-3 undertake studies to determine potential regulatory actions and appropriate frequencies for autonomous maritime radio devices.

This agenda item relates to consideration of, based upon the results of ITU-R studies: modifications of the Radio Regulations, including new spectrum allocations to the maritime mobile-satellite service (Earth-to-space and space-to-Earth), preferably within the frequency bands 156.0125-157.4375 MHz and 160.6125-162.0375 MHz of Appendix 18, to enable a new VDES satellite component, while ensuring that this component will not degrade the current terrestrial VDES components, ASM and AIS operations and not impose any additional constraints on existing services in these and adjacent frequency bands.

This agenda item relates to consideration of issues related to wireless access systems, including radio local area networks (WAS/RLAN), in the frequency bands between 5 150 MHz and 5 925 MHz, and take the appropriate regulatory actions, including additional spectrum allocations to the mobile service, in accordance with Resolution 239 [COM6/22] (WRC-15).

The ITU-R is invited to:

1. study WAS/RLAN technical characteristics and operational requirements,
2. conduct studies with a view to identify potential WA/RLAN mitigation techniques to facilitate sharing with incumbent services at 5 150 - 5 350 MHz, 5 350 - 5 470 MHz, 5 725 - 5 850 and 5 850 - 5925 MHz,
3. to perform sharing and compatibility studies in the band 5 150 - 5 350 MHz of the possibility of enabling outdoor WLAN/RLAN operations
4. to conduct further sharing and compatibility studies between WA/RLAN applications and incumbent services at 5 350 - 5 470 MHz addressing:
   1. whether additional mitigation techniques would provide coexistence with EESS (active) and SRS (active) systems,
   2. with radio determination systems and,
   3. hence whether an allocation could be made to the mobile service for use by WAS/RLANs,
5. to conduct detailed sharing and compatibility studies including mitigation techniques between WAS/RLAN and incumbent services in the band 5 725 - 5 850 MHz with a view of enabling a mobile service to accommodate WAS/RLAN use, and
6. to conduct detailed sharing and compatibility studies including mitigation techniques between WAS/RLAN and incumbent services in the band 5 850 - 5 925 MHz with a view to accommodating WAS/RLAN use under the existing mobile allocation while not imposing any additional constraints on the existing services.

This agenda item relates to studies on the technical and operational aspects of radio networks and systems, as well as spectrum needed, including possible harmonized use of spectrum to support the implementation of narrowband and broadband machine-type communication infrastructures.
