    Subcommittee 1: Experimental Techniques

    The purpose of this sub-committee is to develop protocols for the measurement of the peak spatial average SAR in simplified models of the head and body of users of radio transceivers used for wireless communications services. It applies to contemporary and future devices with the same operational characteristics as contemporary devices that operate in the 300 MHz–6 GHz frequency range and provides a conservative estimate of the peak spatial average SAR representative of that which would be expected to occur in a significant majority of persons during normal use of these devices, but which may not be the absolute maximum value that could possibly occur under every conceivable combination of size and shape of the body, device orientation, and spacing relative to the body.

    Subcommittee 1 was established in February 1997. The scope of Subcommittee 1 covers a variety of devices. It initially focused on a recommended practice devoted exclusively to handsets used for personal wireless communication services. The first IEEE 1528 standard (IEEE Std 1528TM-2003) specifies protocols for the measurement of the peak spatial-average SAR in the head of users of certain hand-held radio transceivers that are used for personal wireless communications, operate in the 300 MHz – 3 GHz frequency range, and are intended to be operated while held against the ear. Specifically, this recommended practice describes the concepts, measurement techniques, instruments, calibration techniques, phantom models for SAR system validation, and limitations of systems used for measuring the radio frequency (RF) electric field strength for purposes of determining the spatial-peak mass-averaged SAR, e.g., per 1 gram or 10 grams of tissue, in simulated tissue models, including homogeneous anatomical models of the human head.

    Protocol requirements of IEEE Std 1528TM-2003, which have been incorporated into IEC Std 62209-1, are the primary globally adopted or referenced standards to assess the SAR in near field exposures.


    Subcommittee 2: Numerical Standards

    The purpose of these standards is to specify numerical techniques and standardized anatomical models used for determining the spatial peak specific absorption rates (SAR) in the human body of users for wireless communication devices. SAR is determined by applying Finite Difference Time Domain (FDTD) or Finite element techniques to simulate the field conditions produced by wireless devices in anatomically correct models of the human anatomy. Intended users of this practice will be (but will not be limited to) wireless communication device manufacturers and wireless service providers that are required to certify that their products comply with the applicable SAR limits and government regulations.

    IEEE/IEC JWG11, IEEE 1528.5 RECOMMENDED PRACTICE FOR COMPUTATIONAL TECHNIQUES TO DETERMINE THE POWER DENSITY OF THE ELECTROMAGNETIC FIELD ASSOCIATED WITH HUMAN EXPOSURE TO WIRELESS DEVICES AND NETWORK EQUIPMENT, 6 GHZ TO 100 GHZ
    This International Standard specifies computational procedures using Finite-Difference Time-Domain (FDTD) and Finite Element Methods (FEM) to assess the peak and spatial-averaged power density relevant to the exposure of the human head or body for devices operating between 6 GHz and 100 GHz. It applies to devices with radiating structures at distances up to and including 200 mm. This includes but is not limited to mobile phones, tablets, and wearables. This standard provides a conservative estimate of the power density of the exposure of the head or body for a significant majority of persons during normal use of these devices.

    This International Standard specifies protocols and test procedures for the reproducible and conservative measurement of the power density (PD) incident to the head or the body by radio-frequency (RF) transmitting devices, with a defined uncertainty. The protocols and procedures apply for a significant majority of people including children during the use of hand-held and body-worn wireless communication devices. These devices may feature single or multiple transmitters or antennas, and may be operated with their radiating part(s) at distances up to 200 mm from a human head or body. This International Standard can be employed to evaluate PD compliance of different types of wireless communication devices used in close proximity to the head and body, combined with other RF-transmitting or non-transmitting devices or accessories (e.g. belt-clip), or embedded in garments. The overall applicable frequency range is from 6 GHz to 300 GHz.

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 standard.

    Guide IEEE1528.7, Guide to assess the EMF exposure of Internet of Things (IoT) technologies
    Scope of this Guide is the identification of appropriate measurement and computational methodologies for the assessment of RF exposure from IoT devices. This guide, will consider the use and operating modes for a wide variety of devices and these will be grouped into a number of categories that follow an appropriate assessment route. This guide will not be able to address all available IoT devices but will offer advice for those that are not addressed. This guide, will try to address the new features that are under development where significant advances are expected in antenna technology and the use of millimeter wave bands.
