Available cellular operators and their RSSI | Telit Cinterion IoT Developer Community

Hi,
I know in a cellular model we can search and find all available operators in a given location my question here is, Is it possible to detect all the vailable operators and their RSSI an a particular location? Is there any modem avilable which supports this kind of feature?
thanks in advance

Hi!
Please use the AT^SNMON="INS",2 command. Please deregister manually first using AT+COPS=2.You will get a list of operator base stations sorted by strongest signal.
This is supported by all current Gemalto modems.
Example of one line of the output for ELS61-E:
^SNMON: "INS",0,"0x00000004",7,"0046602","71C1","24405",1825,115,20,20,-77,-10
"7" means LTE, "24405" is operator Elisa in Finland, "-77" is the RSSI.

Please have a look at https://iot-developer.thalesgroup.com/showcase/cell-id-based-positioning... .
It is a very good Cell ID based positioning demo which is using the SNMON-command.
You can also limit the searched radio access technologies, see: https://iot-developer.thalesgroup.com/threads/pds6-network-monitoringban... .

Thanks Antero
We tried these commands "AT^SNMON="INS",2" on PLS8-X modem.
We are getting "+CME ERROR: invalid index" error.Would this module support this feature?
Modem details (Response of ATI1):
"Cinterion
PLS8-X
REVISION 03.017
A-REVISION 01.000.05"
Thanks in advance.

Hello,
For this module the AT^SNMON command is a little different than for ELS61. Please try AT^SNMON="PDM",2. See more in the AT commands specification document.

Hi,
we are seeing below response for the command
AT^SNMON="PDM",2
^SNMON: "PDM",0,-1,2,1,0,-1,-1,0,0000
As per the AT command specs doc,
response format is [^SNMON: "PDM", <reserved>, <ta>, <nom>, <rac>, <dsac_avail>, <dsac_cs>, <dsac_ps>,<tac_avail>, <tac>]

Hi,
Any update on this? we are not seeing list of operator base stations sorted by strongest signal
with the AT^SNMON="PDM",2 command.

Hello,
For this module AT^SNMON command has different functionality because "PDM" displays different parameters than "INS". For neighboring cells monitoring there is AT^SMONP command but it also has a different functionality than AT^SNMON="INS". You can display the available operators with at+cops=? but I can't see the other command that would give you the functionality of AT^SNMON="INS".
