Meetings of working parties WP1A and WP1B - Geneva

Geneva hosted on 22-30 November 2016 meetings of the working parties 1A (WP 1A) and 1B (WP 1B) that preceded the 2015 Radiocommunication Conference (WRC-15), focusing on the study period (2015-2019) before the next WRC, due to be held in 2019 (WRC-19).

At the WP 1A meeting the proposed recommendation on frequency ranges for global or regional operation and human hazards of non-beam wireless power transmission (WPT) systems, which includes just non-beam technologies, continued to be developed. Notably, in this proposed recommendation only the 6765-6795 kHz frequency band (for magnetic resonant technology for mobile devices) is proposed for regional or global harmonisation of WPT systems.

The report ITU-R SM.2303-1, on wireless power transmission using technologies other than radio frequency beam was also revised, particularly to include a new section on WPT systems’ compatibility with broadcasting service.

The report ITU-R SM.2392-0 on applications of wireless power transmission via radio frequency beam was approved by study group 1 (SG1) in June 2016; a contribution was submitted to this meeting with revision proposals that were noted and will be considered in the future. Given that the report ITU-R SM.2392-0 only describes beam technologies and research projects, the last WP 1A meeting in June 2016 decided to begin production of a new report to assess the impact of beam WPT systems on radiocommunication services, which continues to be developed.

The main frequency bands under consideration for beam WPT are 2.4 GHz and 5.8 GHz. The reports on smart grid utility management systems and ITU-R SM.2028-1 on Monte Carlo simulation methodology for use in sharing and compatibility studies between different radio services or systems were also revised.

At the WP 1B meeting, the group continued work on a recommendation concerning global harmonisation of SRD categories, which proposes the development of common definitions for some categories of short range devices where the existence of some level of harmonisation has been verified at global level; a new category was included, namely ultra low power active medical implant.

WP 1B is responsible for item 9.1 of the WRC-19 agenda (issue 9.1.6), concerning WPT systems in electric vehicles. It has continued to duly develop the text on the Conference Preparatory Meeting for WRC-19 and begun drawing up a new report on the methodology for spectrum management of WPT, which aims to explain and define the regulatory framework for such systems.

The proposed report on spectrum management principles, challenges and issues related to dynamic access to frequency bands by means of radio systems employing cognitive capabilities continues to be developed. This working item began with the so-designated topic of white spaces in the ultra high frequency band based on cognitive techniques and has evolved to become a more generic topic through systems that employ cognitive techniques.

Recommendation ITU-R SM.1896 on frequency ranges for global or regional harmonization of short-range devices was also revised, specifically to include frequency bands for ultra broadband technology with the aim of regional and global harmonisation for such technology.

WP 1B is also producing a report on innovative regulation tools, specifically on innovative regulatory tools to support enhanced shared use of the spectrum and the infrastructure of telecommunications networks, which was revised at this meeting and no longer includes infrastructure sharing as a regulation tool. Hence, the report now considers two regulatory tools: licensed shared access to share spectrum of different services, and shared spectrum access for similar technologies, to share spectrum of similar technologies/systems.

Proposals were also made to revise Recommendation ITU-R SM.1413 on the Radiocommunication Data Dictionary and Recommendation ITU-R SM.1046 on the definition of spectrum use and efficiency of a radio system.
