Various methods are known in the art for performing a standardized measurement of averaged SAR values, e.g. 1 g or 10 g averaged SAR values, using a standardized phantom or human body model, e.g. an anthropomorphic phantom, to assess SAR values, such as the ESM-120 (Maschek, Germany), DASY (SPEAG, Switzerland), cSAR3D (SPEAG, Switzerland) and iSAR (SPEAG, Switzerland) systems. However, most of such methods known in the art are adapted for providing 1 g or 10 g averaged SAR values.
Specific numerical tools are known in the art, such as SEMCAD-X (SPEAG, Switzerland) and Sim4Life (SPEAG, Switzerland), that allow one to use numerical human body models in order to provide SARwb-values. For example, such numerical methods may use an MRI model of a specific subject. However, to achieve a highly specific estimate of SARwb for a particular human subject, such methods would also require a detailed measurement of the subject's dielectric properties, which may not be possible in living humans using methods known in the art.
Another approach for the determination of SARwb uses the concept of ‘room electromagnetics’, a theory which studies the propagation and absorption of electromagnetic fields using methods from room acoustics. This theory established a relationship between the reverberation time, a time constant of the decay of electromagnetic power in a room, and the electromagnetic radiation absorption in a room. For example, Bamba et al. disclosed an application of room electromagnetics for determining SARwb in “Experimental Assessment of Specific Absorption Rate Using Room Electromagnetics,” IEEE Transactions on Electromagnetic Compatibility, 54(4), pp. 747-757. However, such approach requires knowledge of the incident power density without the subject present, which cannot be directly determined when the monitored person is present. Wireless communication systems are widely deployed to provide various types of communication content such as voice and data. Typical wireless communication systems may be multiple-access systems capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, and the like). Examples of such multiple-access systems may include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA)
