1.15.2 Jamming detection
In real network situations modules can experience various kind of out-of-coverage conditions: limited service
conditions when roaming to networks not supporting the specific SIM, limited service in cells which are not
suitable or barred due to operators’ choice, no cell condition when moving to poorly served or highly
interfered areas. In the latter case, interference can be artificially injected in the environment by a noise
generator covering a given spectrum, thus obscuring the operator’s carries entitled to give access to the
LTE/3G/2G service.
The congestion (i.e. jamming) detection feature can be enabled and configured by the +UCD AT command:
the feature consists of detecting an anomalous sources of interference and signaling the start and stop of
such conditions to the host application processor with an unsolicited indication, which can react
appropriately by e.g. switching off the radio transceiver of the module (i.e. configuring the module in
“airplane mode” by means of the +CFUN AT command) in order to reduce power consumption and
monitoring the environment at constant periods (for more details, see the TOBY-L3 series AT command
manual [2]).
1.15.3 IP modes of operation
IP modes of operation refer to the TOBY-L3 series modules configuration related to the network IP
termination and network interfaces settings in general IP modes of operation are following:
