Abstract: An adaptive multiband access communication system and method for a network of downhole components located in a wellbore are disclosed. Low noise regions of a communication spectrum are identified and frequency channels within the low noise regions are assigned to the downhole components. Communications on the assigned channels are monitored for quality and adjustments are dynamically made to frequency channel assignments if the quality does not satisfy an acceptance criterion.
