How it works


With each phone call, Zetro applies the following 3 steps.


(1) All mobile phone models are designed and built differently and as a result emit different power output levels. Although phone manufacturers do not make this information available to you, we have taken on this role by accessing your phone during operation and determining key variables such as network type, signal strength, frequency, channel, impedance and several other phone and network parameters.

Point 1

(2) Zetro uses your mobile phones internal variables along with a combination of complex mathematical calculations and network statistics to calculate the total effective radiated power (Electromagnetic Energy EME) being emitted from your phone.

Point 2

(3) With each phone call, Zetro utilizes all this information gathered, to measure EME levels generated by your mobile phone in real time and display results in an easy to understand way .
