RF telemetry link quality assessment system and method
First Claim
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.

Abstract
A system and method for assessing link quality for radio frequency (RF) transmissions between a programmer and an implantable medical device (IMD) is provided. An embodiment of the method includes measuring a plurality of available wireless communication channel potentially used to communicate between an implantable medical device (IMD) and a programmer to determine signal and noise levels for the channels. The method also includes storing the signal and noise levels. The method further includes processing the stored levels to determine the interference potential on the channels adjacent to the available channels. In this embodiment, the method also includes selecting a preferred communication channel based on a function of noise level for a target center channel and interference potential for corresponding adjacent channels to the target channel. Other aspects and embodiments are provided herein.

14. A system, comprising:
-
means for measuring a plurality of available wireless communication channels potentially used to communicate between an implantable medical device (IMD) and a programmer to determine respective signal and noise levels for the channels; means for storing the signal and noise levels; means for processing the stored levels to sort the available channels by noise level, and for processing the stored levels to determine the interference potential on the channels adjacent to the available channels; and means for selecting a communication channel based on a lowest sum of noise level for a target center channel plus interference potential for corresponding adjacent channels to the target channel. - View Dependent Claims (15, 16)
