Detectionrange of radio signal source is determined by its radiated power andsensitivity of the field indicator. In cell phones radiated power depends onthe reception conditions, such as distance from the base station, locationinside or outside the building, etc. and can vary significantly. Thetypical values and limits of detection range of radio signal sources for theRAKSA iDet field indicator are as follows:
GSM cell phone: radiated power -20 - +30 dBm, detection range 0.3 - 80m, typical value 10 - 20 m.
UMTS cell phone: radiated power -40 - +20 dBm, detection range 0.03 - 30m, typical value 2 - 3 m.
DECTwireless phone: radiated power -20 dBm, detection range 8 m.
Wirelessmicrophone for secret information retrieval : radiated power 0 - +10 dBm,detection range 3 - 10 m.
Thelimits of the transmitter power corresponding to the dynamic range of the RAKSAiDet field indicator are as follows:
at thedistance of 1 m from the transmitter 0.15 mW - 15 W
at the distance of 3 m fromthe transmitter 1.4 mW - 140 W
