Parameter Description Range Default Notes
<par1> range LTE band EARFCN range
[139650-141589] TDD 41 [39650 - 41589]
Table 10: <par1> parameter range
The "+CME ERROR: operation not supported" or
"+CME ERROR: 4" error result code will be provided in
these cases (depending on the +CMEE AT command
setting):
o A value not belonging to the above ranges is
set
o The RX channel parameter value belongs to a
not supported RAT (2G or 3G or 4G RAT) or
band
<par2> Time 1 ÷ 600000 1000 Time interval for RX test expressed in ms
<par3> Antenna diversity 0 ÷ 1 0 Receiver path:
o 0: main / primary antenna
o 1: diversity / secondary antenna
The parameter is available only if supported, otherwise
an error result code will be provided ("+CME ERROR:
operation not supported" or "+CME ERROR: 4" depending
on the +CMEE AT command setting)
<min> Minimum antenna
RF level estimation
-100 ÷ -20 Expressed in dBm, for 2G RAT
SARA-R4 / SARA-N4
The range goes from -75 to -20.
<avg> Average antenna
RF level estimation
-100 ÷ -20 Expressed in dBm, for 2G RAT
SARA-R4 / SARA-N4

Parameter Description Range Default Notes
<par1> Tx channel 0 ÷ 165535 32 TX channel 2G RAT: for 850, 900, 1800 bands the value
corresponds to ARFCN while for 1900 band an offset of
32768 is added.
o [0-124]: GSM 900 MHz
o [128-251]: GSM 850 MHz
o [512-885]: DCS 1800 MHz

o [33280-33578]: PCS 1900 MHz (corresponding to
ARFCN 512-810 range in band 1900)
TX channel 3G RAT: the value corresponds to UARFCN
except for the band 19 where an offset of 20000 is added,
additional channels available in some 3G bands are not
supported.
o [1312-1513]: band 4 (1700 MHz)
o [2712-2863]: band 8 (900 MHz)
o [4132-4233]: band 5 (850 MHz)
