Patent ID: 8340166

Claim:
An electrical infrastructure noise detection system, comprising: a wireless receiver operable to receive one or more radio frequency signals and one or more symbols present in the one or more received radio frequency signals on a communication link; an error detector operable to detect the presence of one or more erred symbols of the one or more symbols; and a pattern identifier operable to determine a correlation in time between the one or more erred symbols and an infrastructure waveform associated with electrical infrastructure, wherein when the determined correlation between the one or more erred symbols and the infrastructure waveform indicates the electrical infrastructure as a source of detectable radio frequency interference to a smart grid device in the noise detection system, the pattern identifier generates a pattern flag, wherein one or more of the pattern flag and a pattern flag representation of the pattern flag are usable to control transmission of packets to the smart grid device to substantially avoid transmission of the packets to the smart grid device during one or more interference periods having a determined correlation between the one or more erred symbols and the infrastructure waveform that indicates the electrical infrastructure as the source of detectable radio frequency interference to the smart grid device.
