8.7 AT^SMONC Cell Monitoring
Description: The AT^SMONC execute command delivers cell information containing 9 values from a
maximum of 7 base stations.
The first base station is the serving cell.
Syntax: Test Command: AT^SMONC=?
Response: OK
ERROR
+CME ERROR: <err>
Exec Command: AT^SMONC
Response: ^SMONC: <MCC>1, <MNC>1, <LAC>1, <cell>1, <BSIC>1, <chann>1,
<RSSI>1, <C1>1, <C2>1, <MCC>2, <MNC>2, <LAC>2, <cell>2, <BSIC>2,
<chann>2, <RSSI>2, <C1>2, <C2>2, ...
OK

+CME ERROR: <err>
Parameter:
<MCC>
Mobile country code
3 digits; e.g., 232
000 Not decoded
<MNC>
Mobile network code
2 digits or 3 digits; e.g., 07 or 003
000 Not decoded
<LAC>
Location area code
4 hexadecimal digits; e.g., 4EED
0000 Not decoded
<cell>
Cell identifier
4 hexadecimal digits; e.g., 4EAF
0000 Not decoded
FFFF Cell ID currently not available because the cell ID information is not yet
read from the Sysinfo 3 transmitted by the base station.
<BSIC>
Base station identity code
2 digits; e.g., 32
00 Not decoded
<chann>
ARFCN (Absolute Frequency Channel Number)
0 Not decoded. In this case, all remaining parameters related to the same
channel are neither decoded. For example, a non-existing cell appears
as follows:
000,000,0000,0000,00,0,0,-,-
<RSSI>
Received signal level of the BCCH carrier (0..63). The indicated value is composed of the measured value in
dBm plus an offset. This is in accordance with a formula specified in 3GPP TS 05.08
<C1>
Coefficient for base station reselection; e.g., 30. In dedicated mode, under certain conditions the parameter
cannot be updated. In such cases a ‘-‘ is presented.
<C2>
Coefficient for base station reselection; e.g., 30. In dedicated mode, under certain conditions the parameter
cannot be updated. In such cases a ‘-‘ is presented.
Notes:
• To some extent, the cell monitoring commands AT^MONI, AT^MONP and AT^SMONC cover the same
parameters. The receiving level, for example, can be queried with all three 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.
• This command is PIN protected.
• This command is not supported in airplane mode.
