| Título | Measurement procedure for the assessment of specific absorption rate of human exposure to radio frequency fields from hand-held and body-worn wireless communication devices – Part 1528: Human models, instrumentation and procedures (Frequency range of 4 MHz to 10 GHz) |
| Resumo | IEC/IEEE 62209-1528:2020 specifies protocols and test procedures for the reproducible and repeatable measurement of the conservative exposure peak spatial average SAR (psSAR) induced inside a simplified model of the head and the body by radio-frequency (RF) transmitting devices, with a defined measurement uncertainty. These protocols and procedures apply to a significant majority of the population, including children, during the use of hand-held and body-worn wireless communication devices. These devices include single or multiple transmitters or antennas, and are operated with their radiating structure(s) at distances up to 200 mm from a human head or body. This document is employed to evaluate SAR compliance of different types of wireless communication devices used next to the ear, in front of the face, mounted on the body, operating in conjunction with other RF-transmitting, non-transmitting devices or accessories (e.g. belt-clips), or embedded in garments. The applicable frequency range is from 4 MHz to 10 GHz. Devices operating in the applicable frequency range can be tested using the phantoms and other requirements defined in this document. The device categories covered include, but are not limited to, mobile telephones, cordless microphones, and radio transmitters in personal, desktop and laptop computers, for multi band operations using single or multiple antennas, including push-to-talk devices. This document can also be applied for wireless power transfer devices operating above 4 MHz. |

| Título | Product standard to demonstrate the compliance of wireless communication devices, with the basic restrictions and exposure limit values related to human exposure to electromagnetic fields in the frequency range from 300 MHz to 6 GHz: devices used next to the ear |
| Resumo | This product standard applies to wireless communication devices used in close proximity to the human ear (e.g. mobile phones, wireless headsets). The applicable frequency range is from 300 MHz to 6 GHz. The objective of this standard is to demonstrate the compliance of such devices with the basic restrictions and exposure limit values related to human exposure to radio frequency electromagnetic fields. For devices used next to the body or in front of the face the applicable product standard is EN 50566:2017. For low power devices the applicable product standard is EN 50663:2017. |

| Título | OET Bulletin 65, Supplement C – Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields, Additional Information for Evaluating Compliance of Mobile and Portable Devices with FCC Limits for Human Exposure |
| Resumo | In August, 1996, the Commission adopted a Report and Order in ET Docket 93-62 amending its rules for evaluating the environmental effects of radiofrequency (RF) electromagnetic fields. Specifically, the Commission adopted new guidelines and procedures for evaluating human exposure to RF emissions from FCC-regulated transmitters and facilities. As a part of this proceeding, new limits were adopted for human exposure to RF emissions from certain mobile and portable devices. Two subsequent FCC Orders were issued to refine and clarify the decisions adopted in the original Report and Order. A revised version of OET Bulletin 65, “Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields” was also issued. One of the areas discussed in Bulletin 65 is compliance with the limits adopted by the Commission for safe exposure to RF emissions due to mobile and portable devices such as non-fixed wireless transmitters and hand-held cellular telephones. The first edition of Supplement C (97-01) was released in 1997. The purpose of this revised supplement is to provide parties filing applications for equipment authorization with guidance on complying with the latest requirements using up-to-date test procedures. This supplement is not intended, however, to establish mandatory procedures, and other methods and procedures may be acceptable if based on sound engineering practice. |

| Título | LTE for UMTS: OFDMA and SC-FDMA Based Radio Access |
| Resumo | From the editors of the highly successful WCDMA for UMTS, this new book gives a complete and up-to-date overview of Long Term Evolution (LTE) in a systematic and clear manner. It starts with an in-depth explanation of the background and standardization process before moving on to examine the system architecture evolution (SAE). The basics of air interface modulation choices are introduced and key subjects such as 3GPP LTE physical layer and protocol solutions are described. Mobility aspects and radio resource management together with radio and end-to-end performance are assessed. The voice solution and voice capacity in LTE are also illustrated. Finally, the main differences between LTE TDD and FDD modes are examined and HSPA evolution in 3GPP Releases 7 and 8 is described. LTE for UMTS is one of the first books to provide a comprehensive guide to the standards and technologies of LTE. Key features of the book include: covers all the key aspects of LTE in a systematic manner; presents full description of 3GPP Release 8 LTE; examines the expected performance of LTE. Written by experts actively involved in the 3GPP standards and product development. |

| Título | Determination of the radiated power through ground-based field strength measurements in the frequency range from 30 MHz to 6000 MHz |
| Resumo | The radiated power of a transmitter is one of the most important parameters which characterise a transmitter and its emissions. Usually, it is not possible to measure the radiated power directly. However, there are two different methods to determine the radiated power indirectly. The first method would measure the transmitter output power and calculate the radiated power by taking into account cable losses and antenna gain. The second method measures the field strength and calculates the radiated power by taking into account the measurement distance and the propagation loss. The purpose of this ECC Recommendation is to provide common measurement methods which will enable CEPT administrations to determine the radiated power of a transmitter in the frequency range from 30 MHz to 6000 MHz from field strength measurements reducing as much as possible the uncertainty of the measurement. |

| Título | IEEE Recommended Practice for Measurements and Computations of Radio Frequency Electromagnetic Fields With Respect to Human Exposure to Such Fields,100 kHz-300 GHz |
| Resumo | Techniques and instrumentation for the measurement and computation of potentially hazardous electromagnetic (EM) fields both in the near field and the far field of the electromagnetic source are specified. The specifications previously set forth in IEEE Std C95.3-1991 are extended and combined. Leakage and near-field measurements and a description of the concepts, techniques, and instruments that can be applied to the measurement of specific absorption rate (SAR) or the electric field strength in organisms (including humans) and phantoms exposed to electromagnetic fields are included. Below 100 MHz, the current flowing through the body to ground is measurable and can be used to determine the SAR and, therefore, a brief treatment of lowfrequency body current measurement is included. |
