The reduction can be seen in the plots on the following pages. The difference in height of the red (no Cell Shield) and blue (with Cell Shield) traces represents the reduction. A 5dB per division scale was used. The Cell Shield on the Verizon phone measured approx. 14dB (96%) reduction, on the Motorola, approx. 3dB (50%) and on the Qualcomm, 3+dB (50-60%). The Qualcomm is difficult to read.
