Abstract: A network system comprising a first network element and a second network element. The first network element is programmed to provide the step of first, communicating to the second network element a plurality of configuration parameter sets. Each configuration parameter set corresponds to a respective frame fragment and comprises a parameter value that differs in value from the parameter value in another configuration parameter set in the plurality of configuration parameter sets. The first network element also is programmed to provide the step of second, communicating a frame, to the second network element, in a plurality of frame fragments, wherein each frame fragment in the plurality of frame fragments is communicated according to a respective parameter value in the plurality of configuration parameter sets.

Abstract: A communication device in a network may receive a stream of frames from the network, in which each frame includes one or more beacon packets. A communication protocol being used by the network may be identified by tracking a preselected field within a sequence of beacon packets, in which the preselected field varies in a first known manner for a first protocol and in a second known manner for a second protocol. The communication device may then join to the network using the identified communication protocol to transmit and receive data.

Abstract: A method of BLE-Mesh communications includes providing a dual-mode BLE-Mesh device including dual-mode RF driver, dual-mode manager, a BLE stack for BLE operations, and a mesh stack for mesh operations in a BLE-mesh network having a BLE relay device and a functional end BLE device. The BLE-mesh device has a periodic set of time indexed data slots common throughout the BLE-mesh network which provides a BLE event timeline for BLE connection events. The dual-mode BLE device implements an event clustering algorithm that delays or advances mesh events with respect to a timing the BLE connection events for clustering together their respective occurrences into continuous BLE/Mesh events to reduce a duty cycle by reducing a number of transitions from active mode to sleep mode and from sleep mode to active mode. The BLE-Mesh device communicates in the BLE-mesh network using the continuous BLE/Mesh events with at least one mesh device.

Abstract: A communication system and method includes receiving payload data of first and second media access control (MAC) frames. A MAC-level protocol is identified in response to the indication of the selected network for each of the first and second MAC frames. The payload data of the first and second MAC frames is transmitted and/or received across respective networks transmitted using, for example, power line communications signals over a common communications medium. The common communications medium is operable for carrying signals of a plurality of networks.
