Parameters
The output contains 9 values from a maximum of 7 base stations. The first base
station is the serving cell.
Values for one base station in output order:
MCC Mobile country code, 3 decimal digits, e.g. 232
Value 000: not decoded
MNC Mobile network code, 2 or 3 decimal digits, e.g. 03
Value 000: not decoded
LAC Location area code, 4 hexadecimal digits, e.g. 3010
Value 0000: not decoded
cell Cell ID, 4 hexadecimal digits, e.g. 4EAF
Value 0000: not decoded
BSIC Base station identity code, 2 decimal digits, e.g. 32
Value 00: not decoded
chann ARFCN (Absolute Frequency Channel Number) of the BCCH carrier,
decimal, e.g. 82.
Value 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, decimal value from
0 to 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, decimal, e.g. 30
C2 Coefficient for base station reselection, decimal, e.g. 30

Note
· In dedicated mode, under certain conditions the parameters C1 and C2 can-
not be updated. In such cases, a ‘-‘ is presented for C1 and C2.
· 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.
