IEEE/IEC Draft International Standard - Assessment of Power Density of Human Exposure to Radio Frequency Fields from Wireless Devices in Close Proximity to the Head and Body (Frequency Range of 6 GHz to 300 GHz) Part 3: Measurement Procedures for Absorbed Power Density
This document specifies protocols and test procedures for repeatable and reproducible measurements of the absorbed power density (APD) that provide conservative estimates of the exposure of the human head or body to radio-frequency (RF) electromagnetic fields (EMF) emitted by wireless communication devices, with a specified measurement uncertainty. These protocols and procedures apply to the evaluation of the exposure of the significant majority of the population during the use of hand-held and body-worn RF transmitting wireless communication devices. The methods apply to devices, with single or multiple transmitters or antennas, that operate with their radiating structure(s) at distances up to 200 mm from the human head or body. The methods of this document can be used to evaluate compliance with applicable APD limits of different types of RF transmitting wireless communication devices used in close proximity to the head and body, with or without RF transmitting or non-transmitting accessories, or of devices embedded in garments. The overall applicable frequency range of the specified protocols and procedures is from 6 GHz to 300 GHz. The categories of wireless communication devices covered in this document include mobile telephones, radio transmitters in personal computers, desktop and laptop devices, and multi-band and multi-antenna devices. The procedures of this document do not apply to APD evaluation of electromagnetic fields emitted or altered by devices or objects intended to be implanted in the body.
