Properties and functions of mobifinder®4 3G/4G/5G:
mobifinder®4 3G/4G/5G is able to cover a wide range.
Free field tests showed a maximum detection distance of 50 meters in 4G or 5G mode. The detection distance in buildings is restricted, especially if the walls consist of ferroconcrete. Typical values in this case are around 15 meters.
With the service key the detection trigger level can be set in the range 12…78dB.
mobifinder®4 3G/4G/5G analyses the specific signal structure of mobile phones. Thus the likelihood of an unwanted alarm generated by other electronic devices is minimal.
mobifinder®4 3G/4G/5G works with a black box recording function. Received signals are stored successively up to200 alarms together with time-stamps. This makes it possible to protocol all mobile phone activities in order to analyze the information at a later date
Main functions of mobifinder®4 3G/4G/5G
mobifinder®4 3G/4G/5G detects cellular phones working in 4G and 5G-DSS mode.
mobifinder®4 3G/4G/5G should always be used together with mobifinder5 for GSM900 & GSM1800, LTE830<E1800 because cellular phones often switch between 5G and GSM/LTE modes..

A clip fastener has been designed so that it can be worn on the breast pocket or belt.
Simple menu-driven parameters setting
LED and LCD indicators are arranged so that signals can not go unnoticed.
An acoustic signal with adjustable volume can, if required, be switched off.
An in-built vibrator mechanism enables the alarm to be transmitted silently.
A 6-digit identification number can be selected by users to identify series of measurements.
