Abstract:
1. A method comprising: operating a device capable of receiving wireless communication signals; and monitoring a selected communication channel with an integrated frequency deviation signal detector to detect whether a wireless communication signal being received over the selected communication channel is a desired communication signal; wherein the integrated frequency deviation signal detector monitors the selected communication channel by: wherein the device is an implantable medical device, the method further comprising: performing a plurality of different phases of sniff operations in an implantable medical device for detecting whether a wake-up communication signal is being received by the implantable medical device over a selected communication channel, wherein one of the phases of sniff operations comprises the monitoring the selected communication channel performed by the integrated frequency deviation signal detector, the method further aborting all of the different phases of sniff operations on the selected communication channel if the integrated frequency deviation fails to fall between the corresponding high and low threshold values.
