cellular phones. These define four cellular phone positions for the standardized head
model SAM: “cheek” and “tilt” for right and left ear use, as illustrated in Figure 5.14a
and b, respectively (Beard et al. 2006). In the “cheek” position, the body of the cellular
phone is placed against the cheek, while in the “tilt” position a projecting antenna is
placed close to the head. These typical positions are expected to produce representative
