Geneva hosted on 2-9 June meetings of the working parties 1A (WP 1A) and 1B (WP 1B) antedating the 2015 World Communications Conference (WRC-15), the focus being the 2015-2019 study period ahead of the next WRC in 2019 (WRC-19).
The WP 1A meeting considered the issue of co-existence of wired telecommunications and radiocommunication systems, including power line telecommunications. Contributions were received for review of the reports “ITU-R SM.2158 - impact of power line telecommunication systems on radiocommunication systems operating below 80 MHz” and “ITU-R SM.2212 - impact of power line telecommunication systems on radiocommunication systems operating in the VHF and UHF bands above 80 MHz”.
Regarding smart grids, the report “ITU-R SM.2351 - smart grid utility management systems” was reviewed. The discussion focused on interference created by light-emitting diode (LED) illumination in broadcasting services, specifically the description of LED illumination’s potential to become a source of electromagnetic interference, namely for the operation of many radio services, a matter that will continue to be studied.
Another major issue with much activity in the group is wireless power transmission (WPT). Work continued on revising the report “ITU-R SM.2303 - wireless power transmission using technologies other than radio frequency beam”. Also approved was the report on applications of wireless power transmission via radio frequency beam.
Regarding applications and services above 275 GHz, in the scope of WRC-19 agenda item 1.15 (275-450 GHz), which is WP 1A’s responsibility, the working plans were determined in order to identify frequency bands in 275-450 GHz for fixed and mobile services.
The following ITU-R recommendations were also subject to editorial revision:
- SM.326 - determination and measurement of the power of amplitude-modulated radio transmitters;
- SM.328 - spectra and bandwidth of emissions;
- SM.1446 - definition and measurement of intermodulation products in transmitter using frequency, phase or complex modulation techniques;
- SM.1879 - the impact of power line high data rate telecommunication systems on radiocommunication systems below 470 MHz.
The WP 1B meeting continued work on drawing up a recommendation for global harmonisation of SRD categories, which proposes the development of common definitions for some short range device categories in which a certain level of global harmonisation has been verified. Also regarding short range devices, the report “ITU-R SM.2153 - technical and operating parameters and spectrum requirements for short-range devices” was subject to editorial revision.
WP 1B is responsible for item 9.1 of the WRC-19 agenda (issue 9.1.6), concerning WPT systems in electric vehicles, and for issue 9.7, satellite Earth stations, and determined the respective working plans for those issues.
WP 1B continues work on drawing up the report on “spectrum management principles, challenges and issues related to dynamic access to frequency bands by means of radio systems employing cognitive capabilities”, a working item which began by considering the matter of white spaces in the ultra high frequency (UHF) band based on cognitive techniques before evolving to more generic focus on dynamic spectrum access via systems that use cognitive techniques.
Lastly, work notably continued on drawing up the report on “innovative regulatory tools to support enhanced shared use of the spectrum and the infrastructure of telecommunications network”, which includes the concept of licensed shared access as developed by the European Conference of Postal and Telecommunications Administrations. The report “ITU-R SM.2012 - economic aspects of spectrum management” was revised, along with Recommendation “ITU-R SM.1046 - definition of spectrum use and efficiency of a radio system” and Recommendation “ITU-R SM.1413 - radiocommunication data dictionary for notification and coordination purposes”.
