Abstract
Systems, methods, and software described herein provide enhancements for monitoring communication data for multiple applications on a wireless device. In particular, a wireless access node is configured to monitor signal to noise data for a first frequency band from a second frequency band. When the signal to noise data meets noise criteria, the access point schedules observation periods in the first frequency band to determine intermodulation distortion for the first frequency band from the second frequency band. Based on the intermodulation distortion meeting distortion criteria, the access point schedules the second frequency band to transmit data only when the first frequency band is neither transmitting nor receiving data.
