<rbp>(str)(+CSCS)
Preferred radio band(s)

The parameter <rbp> may be one of the single bands or one of the four dualband combinations listed below. All preferred bands must be contained in the range of allowed bands (see <rba>), otherwise the write command will return ERROR. Invalid combinations will neither be accepted, resulting in "+CME ERROR: invalid index". To give priority to a certain single band or band combination and suppress all others simply select the same value both for <rbp> and <rba>.

<rbp> primarily serves to trigger the network search, i.e. it is only used one time for searching and selecting a network. As the currently used band depends on the availability of the allowed networks the value indicated by <rbc> may be different from <rbp>. Also, next time a network search is necessary, for example after restart, the ME will first try to reselect the network last used, which may be different from the value of <rbp> last given. Therefore, the setting of <rbp> will not be saved.

The value range of <rbp> is "1...12", but only the bands or band selections listed below are allowed. Trying to set an unsupported value will be denied with "ERROR". To select or deselect a band calculate the sum of the values of all desired bands and enter the resulting value. For example, for GSM 1800 MHz (2) and GSM 850 MHz (8) please enter the value (10).

“1“	GSM 900 MHz
“2“	GSM 1800 MHz
“4“	GSM 1900 MHz
“8“	GSM 850 MHz
“3“	GSM 900 MHz + GSM 1800 MHz
“5“	GSM 900 MHz + GSM 1900 MHz
“10“	GSM 850 MHz + GSM 1800 MHz
“12“	GSM 850 MHz + GSM 1900 MHz

<rbc>(str)(+CSCS)

Currently selected radio band(s)

The band(s) indicated with <rbc> are all allowed bands found at a location area. This means, if prompted to select a network the ME will search for these networks only. The value can be either a single band or a dualband combination.

<rbc> is only a response parameter returned either after sending the read command AT^SCFG? or writing AT^SCFG="Radio/Band".

In addition to <rbc> and to allow the subscriber to be notified whenever the selected band changes it is recom- mended to activate the "+CIEV" (see Section 3.3, AT^SIND).
