3.3 Signal Strength Indicator
When setting up the system it is important to know the strength of signal for reliable opera-
tion. To receive a message showing the Received Signal Strength Indicator (RSSI) the CSQ
command is sent to the system as follows:
CSQ
When the system SIM card has sufficient credit a SMS text message is sent to the number
which sent the command displaying the current RSSI.
e.g. >RSSI 21
It is recommended that the minimum signal level for the installation is 12 (-83dBm) to en-
sure reliable operation. The system will operate below 8 (–100dBm) but may become
unresponsive at times.
The CSQ command will respond to any number that sends it not just master numbers.
To achieve an improved RSSI the standard antenna can be upgraded to a model with
higher gain and/or the antenna should be positioned in an area with less physical ob-
struction. An extension lead can be attached to the SMA connector on the PCB to lo-
cate the antenna away from the control unit housing.
