Patent ID: 8111718

Claim:
A method of operating a communication system, comprising: acquiring, by a scanning device coupled to a first device and a second device, a first frequency band for the first device to wirelessly communicate a first data stream, wherein the center frequency of said first frequency band is f 1 ; acquiring, by the scanning device, a second frequency band for the second device to wirelessly communicate a second data stream, wherein the center frequency of said second frequency band is f 2 , wherein f 2 is higher than f 1 ; scanning, by the scanning device via the second device, to find a third frequency band that is below the first frequency band and is available, wherein the center frequency of said third frequency band is f 3 ; scanning, by the scanning device via the second device, to find a fourth frequency band that is above the second frequency band and is available, wherein the center frequency of said fourth frequency band is f 4 ; if the scanning device determines that (f 1 −f 3 )/(f 4 −f 1 )>1, acquiring f 3 and assigning it to said second device as assigned frequency f A ; and if the scanning device determines that (f 1 −f 3 )/(f 4 −f 1 )<1, acquiring f 4 and assigning it to said second device as assigned frequency f A .
