Allgemeine Informationen
antenna and TETRA signal were designed to simulate actual exposure of a TETRA hand-set; radio frequency background fields (broadband 100 kHz to 3 GHz) in the shielded exposure room were below 0.2 V/m, and low frequency electric and magnetic fields from power lines (50 Hz) were 2.1 V/m and max. 320 nT
