Simulation using Radio Mobile. (questions about Frecuency)

I have a question about min-max frecuencys, if i´m going to use AU frecuencys i was wondering what range should i put on the software?

the entire band range frequency:
915Mhz - 928Mhz

sub-band with 8 channels
915.2Mhz - 916.6 Mhz

or the range frequency of 1 channel (Bw= 200khz)
915.2Mhz - 915.4 Mhz



This seems relatively meaningless.

Either your simulator is aware of the applicable regional parameters (which go far beyond simply frequency), or its conclusions have little practical meaning.
