Abstract: Systems and methods for designing, using, and/or implementing hybrid communication networks are described. In various embodiments, these systems and methods may be applicable to power line communications (PLC). For example, one or more of the techniques disclosed herein may include methods to coordinate medium-to-low voltage (MV-LV) and low-to-low voltage (LV-LV) PLC networks when the MV-LV network operates in a frequency subband mode and the LV-LV network operates in wideband mode (i.e., hybrid communications). In some cases, MV routers and LV routers may have different profiles. For instance, MV-LV communications may be performed using MAC superframe structures, and first-level LV to lower-level LV communications may take place using a beacon mode. Lower layer LV nodes may communicate using non-beacon modes. Also, initial scanning procedures may encourage first-to-second-level LV device communications rather than MV-to-first-level LV connections.

Abstract: A system and method for arbitrating channel access in a wireless device including co-located network transceivers are disclosed herein. A wireless device includes a first wireless transceiver and a second wireless transceiver. The first transceiver is configured for operation with a first wireless network. The second transceiver is configured for operation with a second wireless network. The wireless device further includes logic that determines which of the first and second transceivers is enabled to transmit at a given time. The logic causes the first transceiver to transmit a notification signal indicating a time period during which the second transceiver of the wireless device will perform a first wireless transaction, and during which, based on receiving the notification signal, a different wireless device performs a second wireless transaction via the second wireless network without transmitting a notification signal.

Abstract: A power line communication (PLC) device comprises a processor and a memory coupled to the processor. The memory is configured to store program instructions executable by the processor to cause the PLC device perform operations. One or more time slots are sequentially scan in each of a plurality of frequency bands. A packet transmitted by a second PLC device to the PLC device over one of the plurality of frequency bands is detected. Additional packets received from the second PLC device across the plurality of frequency bands based, at least in part, upon the detected packet are synchronized. The additional packets are organized in a plurality of frames, each of the plurality of frames having been transmitted by the second PLC device to the PLC device over a respective one of the plurality of frequency bands. Each frame has a plurality of time slots, and each time slot has a pair of beacon and bandscan packets, Each bandscan packet includes information indicating a frequency band distinct from any of the plurality of different frequency bands to be used by the second PLC device to communicate with the first PLC device in a direction from the second PLC device to the first PLC device.

Abstract: Apparatus and methods implement aggregation frames and allocation frames. The aggregation frames include a plurality of MSDUs or fragments thereof aggregated or otherwise combined together. An aggregation frame makes more efficient use of the wireless communication resources. The allocation frame defines a plurality of time intervals. The allocation frame specifies a pair of stations that are permitted to communicate with each other during each time interval as well as the antenna configuration to be used for the communication. This permits stations to know ahead of time when they are to communicate, with which other stations and the antenna configuration that should be used. A buffered traffic field can also be added to the frames to specify how much data remains to be transmitted following the current frame. This enables network traffic to be scheduled more effectively.

Abstract: Authentication of a networked device with limited computational resources for secure communications over a network. Authentication of the device begins with the supplicant node transmitting a signed digital certificate with its authentication credentials to a proxy node. Upon verifying the certificate, the proxy node then authenticates the supplicant's credentials with an authentication server accessible over the network, acting as a proxy for the supplicant node. Typically, this verification includes decryption according to a public/private key scheme. Upon successful authentication, the authentication server creates a session key for the supplicant node and communicates it to the proxy node. The proxy node encrypts the session key with a symmetric key, and transmits the encrypted session key to the supplicant node which, after decryption, uses the session key for secure communications. In some embodiments, the authentication server encrypts the session key with the symmetric key.

Abstract: A method and apparatus for dynamic medium switching in a hybrid network. A method for packet transmission by a combo device includes maintaining a wireless network confidence rating value that is indicative of packet transfer reliability of a wireless network accessed by the device. A wired network confidence rating value that is indicative of packet transfer reliability of a wired network accessed by the device is also maintained. One of the wireless network and the wired network to be used for initial transmission of the data packet is selected based on which of the wireless confidence rating value and the wired confidence rating value is indicative of a higher likelihood of the packet being successfully transmitted. The packet is routed to be transmitted via the selected network.
