1. A method, comprising:

  • measuring a plurality of available wireless communication channels potentially used to communicate between an implantable medical device (IMD) and a programmer to determine signal and noise levels for the plurality of channels;

    storing the signal and noise levels;

    processing the stored levels to determine an interference potential on the channels adjacent to the available channels;

    performing a link quality assessment (LQA) for each of the plurality of available wireless communication channels, wherein the LQA includes, for each channel analyzed as a target channel, using the noise level for the target channel and interference potential for corresponding adjacent channels to the target channel as inputs to a function to provide a value for the LQA for the target channel; and

    selecting a preferred communication channel based on the LQA for each of the plurality of available wireless communication channels.
