7.3 AT^MONP Monitor neighbour cells
Cell information can be issued in the form of periodic outputs (depending on <period> set with the
Write command), or it can be queried directly using the Execute command.
Test command
AT^MONP=?
Response
^MONP: (list of supported < period >s) OK
Write command
AT^MONP
=<period>
The Write command can be used to retrieve information of up to six neighbour
cells automatically every n seconds. To stop the presentation type any character.
Response
See execute command
Parameter
<period> 1 – 254 Display period in seconds
Execute command
AT^MONP
The Execute command can be used to obtain information of up to six neighbour
cells on request.
Parameters

dBm Receiving level in dBm
MCC Mobile Country Code (first part of the PLMN code)
MNC Mobile Network Code (second part of the PLMN code)

Note
· Due to the fact that not all necessary information of the neighbour cells can be
decoded during a connection, there are several constraints to be considered:
- Only neighbour cells that have already been visible in IDLE mode will be
further updated, as long as they are still included in the list.
- Though new neighbour cells can be added to the list (e.g. due to hand-
over), their C1 and C2 parameters cannot be displayed until the connec-
tion is released. In this case “-“ is presented for C1 and C2.
- To some extent, the cell monitoring command AT^SMONC covers the
same parameters. The receiving level, for example, can be queried with
both commands. Yet the resulting values may be slightly different, even
though obtained over a time period of a few seconds. This is quite normal
and nothing to worry about, as the cell information is permanently updated.
