Quanta Guard

QUANTA Guard is a Health and Fitness application for those who are interested in promoting healthy environment by following up and limiting their exposure to radio-frequency (RF) emission from their phones.

Quanta Guard is based on Cellraid's proprietary QUANTA Algorithm that has been validated in extensive laboratory tests to accurately estimate RF emission from mobile devices. QUANTA Monitor is the first technological innovation based application in the world measuring the users RF exposure continuously both in real time and cumulatively. QUANTA Monitor takes into account all RF emission including the invisible emission caused by data usage, a major source of RF emission in modern smart phones. It runs invisibly in the phone and you can see on the display if the governmental limits (SAR limits) for RF emission from the phones are exceeded.


Real time RF emission from the mobile device and actual RF exposure
QUANTA Guard is an application that enables you to monitor radio-frequency (RF) emission from your mobile device in real time and further to monitor how much of the RF emission you are actually exposed to in real time.
Measures obtained are:
- Real time power density (μW/m2) from the mobile device
- Real time SAR (W/kg) from the mobile device
- Real time exposure to the RF emission (given both in SAR and power density values)

RF emission measuring from the mobile device (power density and SAR) takes place continuously, but actual exposure to RF emission is considered to take place and calculated only when the device is held close to the body. This differentiation is facilitated by the ability of QUANTA Monitor to detect the position of the mobile device, that is whether the device is in a close proximity (against the head or in a hand, lap or in a pocket) or further away from the body, for example on a table.

Reduce your RF exposure and avoid SAR excursions
With QUANTA Guard you will be able to reduce your RF exposure. Application constantly monitors your SAR exposure and based on that is automatically reducing up to 90 % of the RF exposure when the phone is in a close proximity to the user without causing a change to the user experience.

In addition QUANTA Cloud service will be available with following features:
- Long term data on real time RF emission and RF exposure and cumulative RF exposure from your phone
- Follow up from all phones and other mobile devices subscribed under same cloud service (Family feature)

Cumulative exposure to RF emission
In addition to real time estimates QUANTA Guard calculates your cumulative exposure to RF emission during different time intervals (hour, day, week, month).

Cumulative RF exposure is calculated as a sum of power density values in a certain time interval (μWh/m2). Cumulative figures help you to categorize the origins of RF emission you are exposed to (phone data traffic, phone calls, cellular towers and Wifi) and to consider how to limit emission from certain origins. It is worth noticing that the actual radio environment is the major factor in cumulative RF exposure, as the minutes spent on the phone have almost no direct correlation to cumulative RF exposure.


In each country regulatory limits for SAR values of mobile devices are complied with and the limits controlled by the national regulatory body. Generally, European countries follow ICNIRP standards (2.0 W/kg) and the North American countries the FCC standards (1.6 W/kg). QUANTA Guard displays if the governmental limits for RF emission from the phones are exceeded.
