Parameter Type Description
<RAT> Number Indicates the Radio Access Technology (RAT):
• 0: LTE Cat M1
• 1: LTE Cat NB1
• 2: GSM
Allowed values:
• SARA-R410M-52B / SARA-R410M-63B / SARA-R410M-73B - 0
• SARA-R410M-02B / SARA-R410M-83B / SARA-R412M - 0, 1
<bitmask1> Number Depending on the <RAT> parameter value, configures the bitmask for LTE or GSM
bands. When <RAT>=0 (LTE Cat M1) or <RAT>=1 (LTE Cat NB1), it indicates the
bandmask for LTE bands 1 through 64. Each bit enables/disables a band:
• Bit 0: band 1
• Bit 1: band 2
• Bit 2: band 3
• Bit 3: band 4
• ..
• Bit 63: band 64
The factory-programmed value for LTE-M bands is:
• SARA-R4 - see Mobile Network Operator profiles
• SARA-N4 - 275063445663 (bands 1,2,3,4,5,8,12,13,17,18,19,20,25,26,28 and 39)
The factory-programmed value for NB-IoT bands is:
• SARA-R4 - see Mobile Network Operator profiles
• SARA-N4 - 185538719 (bands 1,2,3,4,5,8,12,13,17,18,19,20,25,26 and 28)
When <RAT>=2 (GSM), it indicates bandmask for GSM bands 800 / 900 / 1800 / 1900.
The following bit enables/disables a band:
• Bit 8: DCS 1800
• Bit 9: ESGM 900
• Bit 20: GSM 850
• Bit 22: PCS 1900
If any other bit of the bitmask is set to 1, the module return an error result code is
issued.
<bitmask2> Number When <RAT>=0 (LTE Cat M1) or <RAT>=1 (LTE Cat NB1), it indicates the bandmask
for LTE bands 65 through 128. Each bit enables/disables a band:
• Bit 0: band 65
• Bit 1: band 66
• Bit 2: band 67
• Bit 3: band 68
• ..
• Bit 63: band 128
The default value is 0 (all bands from 65 to 128 disabled).
If <RAT>=2 (GSM) the parameter is not supported.
