Even the most restrictive limits of 6 V/m are fully respected in the surrounding of the bed. Fig. 10(b) shows instead a numeric simulation [36] using a realistic voxel-based
human body model [37] exposed to an electromagnetic field simulating the reader’s radiation (3.2WEIRP in the very worst case of unitary duty cycle), for increasing reader-body distance. The estimated SAR is compliant even with the most restrictive European constraint for a distance roughly longer than d(min)= 10-15cm from the reader which is fully compatible with the concept of remote monitoring.
