Radiation Reduction Test Results
Headsets provide safe hands-free communication. Using a GN Netcom headset with a mobile phone reduces radiation by at least 80%, compared to using a mobile phone without a GN Netcom headset.
This is the result of a test carried out by "Telelaboratoriet" at TeleDanmark, an internationally accredited testing facility for telecommunication equipment.
The test was conducted using three of our most popular mobile headsets and three different types of mobile phone. All trials showed that, when using a GN Netcom headset, radiation was reduced by at least 80% and in some cases even up to 90%, compared to using any of the mobile phones without a headset.
A series of tests was performed in order to compare the relative difference in electromagnetic field strength levels at different carrier frequencies inside a human head simulator, using different types of GSM900 and DCS1800 mobile terminals operated alternatively in "handheld" mode and in "headset" mode.
The tests were carried out on Wednesday April 5, 2000 and used the following equipment:
Headsets: GN Netcom M2120, GN Netcom M2320 and GN Netcom M3120
Mobile phones: Nokia 6150, Ericsson A1018S and Motorola Timeport / Triband GSM/DCS Network simulator.
Human head simulator filled with 0.9% NaCl water solution with an inserted isotropic E-field probe to measure radiation (E-field strength)
Test configuration:
The measurements were performed inside the human head simulator with the probe just touching the wall of the head. The center of the probe was located at the center of the ear-channel of the human head simulator.
In handheld mode, the phones were located with the center of the earpiece matching the center of the ear-channel of the human head simulator.
In headset mode, the headsets were located with the ear-piece center matching the center of the ear-channel of the human head simulator.
Measurements were made in a RF anechoic room to simulate "field" conditions without any interference from other radio transmitters (including mobile phone transmitters) in the area.
GN Netcom engineers and manufactures products to the highest available industry standards for safety and performance such as: ETS 300 342-1, EN 50082-1, BABT 85/013, EN 60950, and UL 1459.
