US Patent 10299142 Wireless network plan with multi band access points

A network planning tool for a merged plan comprising multi-band access points having radio groups merges at least a first and a second frequency-band-specific plan. Firstly, a set of pairs, each pair having a radio from the first plan as a first element and a radio from the second plan as a second element is created and utilities are assigned to the pairs. Then a subset of pairs that maximizes a sum of utilities and contains any radio from the first and second plan at most once is selected. The merged plan is created by placing radios in a pair in the selected subset into the same radio group and selecting a location of the radio group based on locations of corresponding radios in the first and second frequency-band-specific plans.
