    Abstract: Systems and methods for routing protocols for power line communications (PLC) are described. In some embodiments, a method performed by a PLC device, such as a PLC meter, may include selecting one or more transmit sub-bands on which to transmit frames, where the transmit sub-bands comprise groups of carrier frequencies. The PLC device then generates a frame comprising a tone map that indicates which transmit sub-bands are used to carry data for the frame. The tone map using two bits per transmit sub-band to indicate a status of each transmit sub-band. The PLC device then transmits the frame on the selected transmit sub-bands. A resolution bit and a mode bit may be used to provide additional information about the transmit sub-bands, such as an amount of power adjustment that has been applied to carrier frequencies and whether dummy bits are transmitted on unused carrier frequencies.

    Abstract: Systems and methods for building, transmitting, and receiving frame structures in power line communications (PLC) are described. Various techniques described herein provide a preamble design using one or more symbols based on a chirp signal that yields a low peak-to-average power ratio (PAPR). According to some techniques, the preamble may be constructed with one or more different types and/or number of symbols configured to identify a PLC domain operating in close physical proximity to another PLC domain. According to other techniques, one or more preamble symbols may be interspersed within a header portion of a PLC frame to facilitate estimation of a frame boundary and/or sampling frequency offset, for example, in the presence of impulsive noise. According to yet other techniques, a PLC detector may be capable of receiving and decoding two or more types of PLC frames (e.g., using different PLC standards).

    Abstract: Systems and methods for application profiles and device classes in power line communications (PLCs) are described. In some embodiments, a PLC device has the device class defined by a PHY layer and may include a processor and a memory coupled to the processor. The memory may be configured to store program instructions, which may be executable by the processor to cause the PLC device to communicate with a higher-level PLC apparatus over a power line using a frequency band. The frequency band may be selected based upon an application profile and/or a device class associated with the PLC device. In some implementations, the higher-level PLC apparatus may include a PLC gateway or a data concentrator, and the PLC device may include a PLC modem or the like. Examples of application profiles include access communications, in-premises connectivity, AC charging, and/or DC charging. Device classes may represent a minimum communication data rate and/or an operating frequency band restriction of the PLC device.

    Abstract: A communication system and method includes a receiver for receiving a communication signal coupled through a physical medium in accordance with a protocol. An interface formed in a single substrate receives from the receiver an indication of the signal strength of the received communication signal. The interface also decodes the information contained in the received communication signal. For example, the interface sends the information decoded from the received communication signal to a first application for consuming the decoded information. The interface also sends the indication of the signal strength of the received communication signal to a second application for generating a quality determination of the physical medium in response to the indication of the signal strength of the received communication signal.
