Geneva hosted last 3-11 July meetings of working parties 1A (WP1A), 1B (WP1B) and 1C (WP1C) of study group 1 (SG1) – spectrum management and engineering. WP1A handles issues associated to spectrum engineering techniques, WP1B spectrum methodologies and economic strategies and WP1C issues involving spectrum monitoring.
Among other matters, WP1A is responsible for:
- Protection of radio services from interference originating in cable systems, specifically:
- power line telecommunications (PLT);
- smart grid power management systems;
- Recommendation ITU-T G.fast (ITU-T G.fast "PSD specification2 and ITU-T G.fast "Physical Layer specification") - standard for cable network interfaces – in copper-wire pair (one or two pairs) with metal reinforcement for broadband distribution (objective: 500Mbps – 1 Gbps) from fibre boxes (located on-street or inside building - FTTB);
- Recommendation ITU T J.195 (J.HINOC) - High Performance Network Over Coax (HiNoC) - standard for coaxial network interfaces that reach speeds identical to those of fibre optics, for their replacement when same is present in the building (FTTB);
- Recommendation ITU-T K.mhn and ITU-T K.60 - present guidelines for resolving interference occurring between radio equipment and cablings or equipment linked to broadband cable networks, operated inside buildings;
- Wireless power transmission (WPT) - the aim of this task was to draw up a report on WPT, presenting its various types, respective frequency bands and power emitted. This equipment comprises wireless chargers that use radio frequency to induce fields and thereby charge terminal equipment, electrical appliances and vehicles (large and small);
- Unwanted emissions - the aim of this task has been to analyse and evaluate the behaviour of digital systems now on the market with respect to unwanted emissions. The subject is controversial, given that some countries (United States of America and Canada) fear that manufacturers see signs of intentions to change the limit (250 percent of bandwidth) where spurious emissions begin, which will impact equipment fabrication.
Among other matters, WP1B is responsible for:
- producing a report on equipment that implements dynamic spectrum access techniques "Preliminary Draft New Report ITU-R SM.[dynamic access]";
- producing a report on different aspects of digital dividend application, mainly focusing on experience in Region 1 countries "Draft new report ITU-R SM.[digital dividend issues]".
