5.2 Jammed Detect & Report Extension
5.2.1 Overview
The Jammed Detect & Report feature allows a
Telit GE864 / GC864
to detect the presence of a
disturbing device such as a Communication Jammer and give indication to the user and/or
send a report of that to the network.
This feature can be very important in alarm, security and safety applications that rely on
the module for the communications. In these applications, the presence of a Jammer
device can compromise the whole system reliability and functionality and therefore shall be
recognized and reported either to the local system for countermeasure actions or to the
network providing remote actions.
An example scenario could be an intrusion detection system that uses the module for
sending the alarm indication for example with an SMS to the system owner, and a thief
income using a Jammer to prevent any communication between the GSM module and the
network.
In such a case, the module detects the Jammer presence even before the break in and
can trigger an alarm siren, other communication devices (PSTN modem) or directly report
this condition to the network that can provide further security services for example sending
SMS to the owner or police. Obviously this last service depends also from network
infrastructure support and it may not be supported by some networks.
