 To find an ideal channel the above data is combined by taking into account the target operational bandwidth and selected band. E.g. on 2.4GHz channels overlap w/ 20MHz bandwidth, but there is no overlap for 20MHz bandwidth on 5GHz.  To find an ideal channel the above data is combined by taking into account the target operational bandwidth and selected band.

-Each valid and possible channel spec (i.e. channel + width) is taken and its interference factor is computed by summing up intereferences ​of each channel it overlaps. The one with least total interference is picked up. +Each valid and possible channel spec (i.e. channel + width) is taken and its interference factor is computed by summing up interferences ​of each channel it overlaps.

 Note: This implies base channel interference factor must be non-negative allowing easy summing up.  Note: This implies base channel interference factor must be non-negative allowing easy summing up.
