A study of mobile phone SAR levels modification in different experimental configurations under 2G and 3G communication standards

Experimental checking of the specific absorption rate (SAR) level modifications when using conductive textiles attached to mobile phone handsets was applied by using the COMOSAR system in both 2G and 3G communication standards. Based on measured data, SAR reduction effectiveness was calculated. Results indicated either shielded or amplified absorbed radiation in the head, depending on the communication technology and on the fabric position to the handset. A discussion based on SAR hotspot position variation with respect to different experimental scenarios is also provided.
