Abstract

The analysis of 11 mobile phone anti-radiation stickers to determine their radiofrequency (RF) attenuation effectiveness was conducted in the laboratory. A spectrum analyser, coupled to a power metre, was used to test the stickers on a basic phone and a smartphone in a Faraday cage. The results showed no exposure reduction properties of the stickers. However, the presence of the stickers on the phone rather led to over a 300,000 % increase in emitted phone RF power and a relatively lower percentage increase by the smartphone.
