Conclusion:
Based on the results from the 300 and 450MHz validations, the derived conversion
factors should over-estimate the SAR for a device operating in the 150MHz band by
approximately 17%. In addition, the above graphs and tabular results show that the probe
conversion factors vary only slightly between head and body as the frequency approaches
450MHz. It is therefore safe to assume that as the frequency is further extended to
150MHz, the difference in the conversion factors between head and body will be less
significant. Therefore, for this reason only one conversion factor is reported for both
head and body at 150MHz.
