Claim Text:
1. A method of operating a wireless access node to limit intermodulation distortion between frequency bands, the method comprising: exchanging first communication signals with wireless communication devices in a first frequency band and a second frequency band, wherein the second frequency band transmits first data when the first frequency band transmits and receives second data; while exchanging the first communication signals, detecting signal to noise data for the first frequency band; determining whether the signal to noise data meets noise criteria for the first frequency band; if the signal to noise data meets the noise criteria, scheduling one or more observation periods for the first frequency band; during the one or more observation periods, determining intermodulation characteristics over the first frequency band from a second frequency band; determining whether the intermodulation characteristics over the first frequency band meet intermodulation criteria; and if the intermodulation characteristics meet the intermodulation criteria, scheduling second communication signals for the first frequency band and the second frequency band, wherein the second frequency band transmits third data when the first frequency band is neither transmitting nor receiving data.
