Abstract :
GSM (Global System for Mobile Communications) phones are part of everyday life. Their emission level is an EMC (Electro-Magnetic Compatibility) issue. It is important to know the peak of signal levels of the mobile phones. They can cause interference with other electronic devices. The emission testing was performed in GTEM-cell (Giga-Hertz Transversal Electromagnetic mode). The measured peak powers in various regimes of the operation were 15.1 mW for conversation and 2 W for ringing and SMS (short message service) message. Use of GSM mobile phones should be used carefully in the vicinity of electronic devices and systems.
