The purpose of this sub-committee is to develop protocols for the measurement for EMF exposure assessment in simplified models of the head and body of users of radio transceivers used for wireless services. It applies to contemporary and future devices with the same operational characteristics as contemporary devices that operate up to 300 GHz frequency range and provides a conservative estimate of exposure levels 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.
Recently wireless technologies have been widespread and additionally used other than hand held devices up to 300 GHz. IoT, 5G communication systems, and Wireless power transfer (WPT) are typical cases. Subcommittee 1 covers all of the measurement methods to show comply with basic restrictions and reference levels. Most WGs under subcommittee 1 are carried out as joint activities with IEC TC106.
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) and power density (PD) for the human body of users of 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 or PD limits and government regulations.
All of WGs under subcommittee 2 are carried out as joint activities with IEC TC106
