<GSM band>,
<WCDMA band>
Set command selects the current band.
Parameter
<GSM band>:
0 - GSM 900MHz + DCS 1800MHz
1 - GSM 900MHz + PCS 1900MHz
2 - GSM 850MHz + PCS 1800MHz (available only on quadri-band
modules)
3 - GMS 850MHz + PCS 1900MHz (available only on quad-band modules)
4 - GSM 900MHz + DCS 1800MHz + PCS 1900MHz
5 - GSM 850MHz + DCS 1800MHz + GSM 900MHz + PCS 1900MHz
(available only in UC864-G Telstra version)
<WCDMA band>:
0 - 2100MHz(FDD I)
1 - 1900MHz(FDD II)
2 - 850MHz(FDD V)
3 - 2100MHz(FDD I) + 1900MHz(FDD II) + 850MHz(FDD V)
4 - 1900MHz(FDD II) + 850MHz(FDD V)
5 - 900MHz(FDD VIII)
6 - 2100MHz(FDD I) + 900MHz(FDD VIII)
Note: This setting is maintained even after power off.
Note: if the ‘four bands’ automatic band selection is enabled
(AT#AUTOBND=2) then you can issue AT#BND=<band> but it will have
no functional effect; nevertheless every following read command AT#BND?
will report that setting.
Band configuration for UC864 family is as followed
UC864-E(FDDI, GSM QUAD)
UC864-G (FDD I / II / V, GSM QUAD)
UC864-WD/E-DUAL (FDD I / VIII, GSM 900/DCS1800)
AT#BND? Read command returns the current selected band in the format:
#BND: <GSM band>, <WCDMA band>
AT#BND=? Test command returns the supported range of values of parameters <GSM
band> and <WCDMA band>.
