The GSM196 monitors the (E)GSM900, GSM1800 and WCDMA/UMTS
2100(3G) bands. It is designed to detect the presence of
unauthorised mobile phones and then help locate them.
In the Handheld mode, a 9-LED signal level display shows
the strongest signal detected and helps to guide the operator
to its source. In the Static mode, alarms are latched so
that the unit can be left unattended, for example overnight,
allowing later analysis.
In both modes, the unit distinguishes between Network signals
(text messages and registrations), GSM calls, and 3G calls,
and indicates both current and past alarms separately for
each type.
Two sensitivity ranges are provided. These are optimised
for detection at a distance and location at closer ranges.
For situations where greater accuracy is required and /
or specific monitoring is required in areas containing multiple
phones, a specially designed directional antenna SA918
system can be used with the GSM196 & GSM196A.
The GSM196A is set-up to the USA, Mexican and South American
networks. This device monitors the GSM850, GSM1900, and
WCDMA2100 (3G) bands.
