Abstract
Disconnected from the powerline, a battery-powered receiver is configured to conserve power. The receiver communicates information between a local controller and a communication network that uses the powerline and a radio frequency (RF) band to propagate messages. An antenna wirelessly detects the presence of the powerline carrier signal that radiates into free space, which indicates a first message encoded onto the powerline. A computer processor wakes up from an inactive state based on the presence of the carrier signal and receives a second message via a second RF signal having a different frequency than the powerline carrier signal, and determines whether the device address in the second message is the assigned address of the receiver. If the message is not addressed to the receiver, the receiver returns to an inactive state.
