Abstract: In a method for communicating with a plurality of devices using different communication protocols, a signal is received at a transceiver device from a neighbor device via a physical layer of a communication media. At a first time the signal contains a header frame from a first device conforming to a first communication protocol and at another time the signal contains a header frame from a second device conforming to a second communication protocol. The transceiver determines which of the different communication protocols is being used by each of the plurality of devices. The transceiver may then process inbound payload data using the indentified protocol type. Data frames are transmitted to the first device using the first communication protocol and data frames are transmitted to the second device using the second communication protocol.

Abstract: A system and method for reducing energy consumption in a wireless network. In one embodiment, a system includes a network coordinator configured to manage access to a wireless network. The network coordinator includes a controller. The controller is configured to define a channel hopping list that specifies on which channel a beacon signal is transmitted in each slot frame of the wireless network. The controller is also configured to set a number of time slots in each slot frame based on a length of the channel hopping list. The controller is further configured to transmit a first beacon signal in each slot frame on a channel specified by the channel hopping list. The number of slots in each slot frame causes the first beacon signal to be transmitted on a same channel in each slot frame.
