590 ITU‐T's Technical Reports and Specifications 1 Introduction Connected devices, distributed sensors and Internet technologies are enabling smart sustainable cities (SSC) to capture valuable data, deploy new services and enhance existing services. The use of these tools can contribute to improving the effectiveness of city management, generating new growth opportunities for local businesses, improving sustainability and raising the quality of citizens’ lives, among other benefits. Wireless technologies and services are playing a pivotal role in enabling smart sustainable cities around the world. Wireless and wired networks provide the underlying connections that underpin smart sustainable cities. The design and deployment of wireless networks must ensure compliance with the required quality of service as well as with the standards and regulations on human exposure to radio frequency (RF) electromagnetic fields (EMFs). Efficient deployment of wireless infrastructure will reduce the transmitted RF power in providing services and support the maximum efficiency for ICTs. 1.1 Scope This Technical Report details the EMF considerations in smart sustainable cities to ensure that the networks and connected devices operate safely and efficiently. The recommendations in this Technical Report are based on existing ITU and WHO technical and policy recommendations. Supplement 1 to Recommendation ITU‐T K.91 includes a Guide on Electromagnetic Fields and Health that provides further information suitable for all stakeholders. The target audiences of this Technical Report include: City officials Town planners Urban developers Infrastructure providers Network operators The public This Technical Report provides guidance on the implementation of good policies for wireless networks and promotes the efficient deployment of smart sustainable cities strategies. This Technical Report features a ‘Smart Sustainable City EMF Check‐list’ designed to provide city officials and planners with a clear and easy‐to‐use reference, in order to ensure the efficient operation of smart city designs while complying with EMF safety standards (refer to Annex 1 for the check‐list). This Technical Report is not intended as a substitute for national EMF and wireless antenna siting requirements. Guidance on terms and definitions in relation to smart sustainable cities can be found in related publications and Technical Reports from the ITU‐T Focus Group on Smart Sustainable Cities. Abbreviations and acronyms are in Annex 4. 1.2 Background Some countries around the world have witnessed the opposition of local stakeholders to the deployment of mobile network antenna sites, and similar smart sustainable city wireless infrastructure. This opposition may be linked to concerns about potential health risks caused by the exposure to EMF, as well as to concerns about aesthetics, impacts on property values, or issues such as privacy of information. With respect to EMF exposure, these fields are imperceptible and
