Read / set the current operating band
This command is used to read or set the current operating bands (1 or
more) of the modem.
Usage:
•
AT!GBAND=<bandmask> sets the operating bands.
•
AT!GBAND? returns the current operating band and the mask of
preferred bands (<band>, <bandmask>).
Parameters:
<band> (current WCDMA or GSM operating band)
•
ASCII string (example: "WCDMA1900", "GSM850", etc.)
<bandmask> (supported bands—use a bitwise OR to choose multiple
bands)
•
GSM850: 0000000000080000
•
GSM900: 0000000000000300
•
GSM1800: 0000000000000080
•
GSM1900: 0000000000200000
•
WCDMA2100: 0000000000400000
•
WCDMA1900: 0000000000800000
•
WCDMA850: 0000000004000000

WCDMA800: 0000000008000000
•
WCDMA900: 0002000000000000
•
Any band: 000000003FFFFFFF (autoband—the modem acquires
any available band)
Example:
You can set the modem to use multiple bands using a bitwise OR. For
example, to set the modem to use the GSM850 and GSM900 bands, you
would issue the command AT!GBAND=00080300:
0000000000080000 (GSM850)
0000000000000300 (GSM900)
-----------------------------
0000000000080300
Note: It is not possible to perform handoffs to bands not in the currently
selected band mask.
Note: Due to stack implementation, the query form of the command
(!GBAND?) reports WCDMA800 for both WCDMA800 and WCDMA850.
