This paper extensively investigates the Specific Absorption Rate (SAR) variations with respect to the category and size of the host device, frequency, and separation distance between a wireless terminal and a phantom. It is shown that SAR variations due to the host device depend on all of the conditions. SAR measurements were also conducted for comparison to the numerical results. The measurement results mostly support the numerically obtained results. Note that more attention should be given on the SAR measurement when the frequency is low such as 835MHz and the separation distance is not short, e.g., 15mm.
