2.1 General

2.1.1 The head and body tissue parameters given in this Part should be used to test transmitters operating in the cellular, PCS, U‑NII, spread spectrum and other frequencies bands (See Reference \[1\], \[3\] and \[4\]). When a transmission band overlaps with one of the target frequencies specified in this Part, the tissue dielectric parameters of the tissue medium at the middle of a device transmission band should be within 5% of the parameters specified at that target frequency. At other frequencies, the dielectric parameters should be linearly interpolated between the closest pair of target frequencies specified in this Part to determine the applicable dielectric parameters corresponding to the middle of a device transmission band. It has been reported that a 5% tolerance in tissue parameters may not be easily achieved at certain frequencies. Under such circumstances, 10% tolerance may be used until more precise tissue recipes are available.
