Tucano’s Anti-Radiation System cases are easy to use, and their performance has been laboratory-tested by Nemko.

Easy-to-use Protection

All Tucano’s anti-radiation cases featuring our new Anti-Radiation System offer you effective protection against electromagnetic waves by attenuating the radio waves emitted towards your body.

The front cover of the anti-radiation cases contains a layer of special material which reduces the radio waves, preventing them from being emitted towards your body.

The phone’s signal strength does not change: you can receive calls and talk without losing any reception quality. As a matter of fact, the back of the telephone is not shielded so as not to obstruct call reception.

Laboratory Tests

Tucano’s Anti-Radiation System cases have been laboratory tested by Nemko, an independent international certification body for electrical and electronic equipment.For each case tested, the emission of radio waves from the telephone was tested with and without the case fitted. The level of reduction of the radiation is measured in decibels, as you can see in this graph. The same test was performed on various cases, using different telephones and the radio frequencies normally used in Europe and most of the world for incoming and outgoing smartphone communications, that is 900 MHz GSM, 1.8 GHz DCS and 2.4 GHz WiFi.

DIDA: The test performed on the Filo case with Anti-Radiation System with 4.7” iPhone 6 on the 900MHz GSM band shows a reduction of 15.55 decibels per milliwatt (dBm).

The Reduction in Radiation

Here are two examples of the results of the tests performed by Nemko on our Anti-Radiation System cases.
The attenuation of the emissions is measured in decibels per milliwatt (dBm).

What exactly is dBm?

This is the unit of measurement used to quantify the difference in the level of radiation emitted by the phone with and without the Anti-Radiation System case.

The decibel per milliwatt, or dBm, is a dimensionless unit of measurement. Unlike metres, litres or volts – which measure precise physical quantities – the decibel estimates the logarithmic relationship between two values of a physical quantity. In this case, the difference measured is the level of radiation from the telephone with and without the Anti-Radiation System case. The decibel unit therefore refers to the milliwatt (hence the abbreviation dBm) with which radio frequency emissions are usually measured. As this is a logarithmic relationship, the value in dBm is not directly proportional to the multiplication factor for the increase or decrease in the level of emissions. This table gives rough conversion values.

Attenuation in dBm Multiplication factor
0 dBm invariato
1 dBm Attenuazione x1,25
2 dBm x1,6
3dBm x2
4 dBm x2,25
5 dBm x3
6 dBm x4
7 dBm x5
8 dBm x6,3
9 dBm x8
10 dBm x10

The Test Method

The method used by Nemko to test the Anti-Radiation System cases is a scientific procedure designed to obtain pure data on the actual reduction in emissions of radio waves.

The tests were performed in an isolated environment, inside an anechoic chamber, that is a room in which the signals cannot reflect off the walls and then be erroneously recorded. This situation reproduces indoors the same conditions which would be found outdoors.

We placed a radio communications device which precisely simulates the signal emitted by the mobile phone antennas on a wooden table, and directly beside it the smartphone. This was tested first without the anti-radiation case and then with the protection offered by the Anti-Radiation System facing outwards. On this side, a receiving antenna recorded the decrease in radiation, measured in decibels per milliwatt (dBm), obtained thanks to the tested case.
