摘要： Systems and methods for channel selection in power line communications (PLC) are described. In some embodiments, a method may include defining a plurality of frames, each frame having a plurality of time slots (710). The method may also include assembling a pair of beacon and bandscan packets within each of time slot of each frame (720). The method may further include sequentially transmitting each of the frames over a corresponding one of a plurality of different frequency bands (725, 730). In some implementations, each bandscan packet may include a slot index indicating its position within its frame and/or a band index indicating one of the plurality of different frequency bands. In response to having transmitted the plurality of frames, the method may include receiving one or more packets indicating a selection of one or more of the plurality of different frequency bands to be used in subsequent communications (935, 1240).

摘要： Systems and methods for carrier sense multiple access (CSMA) protocols for power line communications (PLC) are described. A method may include performing a virtual carrier sensing operation and, in response to the virtual carrier sensing operation indicating that a communication channel is idle, calculating a contention window (602). The method may also include performing a physical carrier sensing operation subsequent to the virtual carrier sensing operation, the physical carrier sensing operation based, at least in part, upon the contention window (604). In response to the physical carrier sensing operation indicating that the communication channel is idle, the method may then include transmitting data over the channel (606). Another method may include determining that a transmission is a unicast transmission and that an acknowledgement message has not been received (607, 608). The method may further include incrementing a backoff parameter (609) and repeating one or more carrier sense operations (602, 604).

摘要： Systems and methods for avoiding access point transmission rate fall-back mechanism having an avalanche effect when acknowledgements are not received for packets sent during co-existence of WLAN and other wireless network technologies. A receiver (210, 300) comprises at least two dissimilar network technology subsystems (340). In some embodiments, a transmitter (220) transmits a handshake to the receiver prior to transmission of at least one data packet and does not reduce a transmission rate of future transmissions to the receiver if the transmitter does not receive a reply to the handshake. In other embodiments, the receiver is able to send an indicator to a transmitter requesting a protection mechanism be employed prior to transmission by the transmitter of at least one data packet. In further embodiments, the receiver is able to negotiate with the transmitter for the transmitter to employ a protection mechanism prior to transmission of at least one data packet to the receiver.
