| Título | 5G technology and human exposure to radiofrequency electromagnetic fields |
| Resumo | The deployment of fifth generation (5G) will see the evolution and expansion of existing fourth generation (4G) networks and the introduction of new radio access networks in millimetre wavebands. As a result of the use of much higher frequency ranges, the number of base stations will substantially increase. These networks will include a range of installations including smaller cell deployments and advanced antenna technologies. Massive multiple input multiple output (MIMO) antennas will allow the use of very narrow beams that will follow the user with an impact on the surrounding exposure level different from that of current systems. The number of wireless devices will dramatically increase. New technology allows for the use of more efficient systems that require lower communication signal levels. Supplement 9 to ITU-T K-series Recommendations contains an analysis of the impact of the implementation of 5G mobile systems with respect to the exposure level of electromagnetic fields (EMFs) around radiocommunication infrastructure. |

| Título | Electromagnetic field considerations in smart sustainable cities |
| Resumo | The content of this Supplement 2 to Recommendation ITU-T K.91 was prepared by the Focus Group on Smart Sustainable Cities (FG‑SSC) and updated within Q3/5 sessions during SG5 meeting. Wireless networks provide vital infrastructure and connection of information and communication technology (ICT) elements that underpin smart sustainable cities. The effective design and careful deployment of wireless networks and short range devices (SRDs) are vital to ensuring electromagnetic field (EMF) compliance and maximum efficiency for ICTs. Key features of this Supplement are: a) It details the EMF considerations in smart sustainable cities. b) It provides guidance on implementation and promotes efficient deployment of wireless networks in smart sustainable cities. c) It features a ‘Smart sustainability city EMF check-list’ designed to provide an easy to use reference for city officials and planners to ensure smart city policies operate most efficiently and comply with EMF exposure standards. d) It references World Health Organization (WHO) materials, International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines, ITU-T Recommendations and IEC Standards. It is not intended to replicate the material in all references. |

| Título | Evaluation techniques and working procedures for compliance with exposure limits of network operator personnel to power-frequency electromagnetic fields |
| Resumo | Recommendation ITU-T K.90 provides evaluation techniques and guidelines for compliance with safety limits for human exposure to electromagnetic fields (EMFs) of telecommunication network personnel (e.g., outside plant craft) at power frequencies (DC, 50 Hz and 60 Hz). This Recommendation does not set safety limits; it seeks to provide techniques and procedures for determining the need for any precautions at the work site. This Recommendation includes an electronic attachment containing the EMFACDC program. |

| Título | Radiofrequency electromagnetic field (RF-EMF) exposure levels from mobile and portable devices during different conditions of use |
| Resumo | Modern mobile devices may be used for many different purposes. There are differences between the ways of using them depending on the service. Also, the exposure to RF-EMF is different depending on the service, environment and the conditions of the use of the mobile devices. This Supplement describes the various factors that determine the level of RF-EMF exposure, as defined by the specific absorption rate (SAR) that is induced in the users of mobile and portable radiocommunication devices. Based on this technical information practical information and guidance is provided for users of mobile devices. |

| Título | Guidance on measurement and numerical prediction of electromagnetic fields for compliance with human exposure limits for telecommunication installations |
| Resumo | Recommendation ITU-T K.61 helps telecommunication operators to verify compliance with exposure standards promulgated by local or national authorities. This Recommendation gives guidance on measurement methods that can be used to achieve a compliance assessment. It also provides guidance on the selection of numerical methods suitable for exposure prediction in various situations. |
