A coordinator for coordinating the use of a physical layer between a first network operating using a first network protocol and a second network operating using a second network protocol different from the first network protocol, the network protocols being non-interoperable and supporting centralized management of nodes by a master device in each network respectively, including a receiver, a transmitter, a coordinator first network type device (CNTD) and a coordinator second network type device (CNTD), both coupled with the receiver and the transmitter, and a synchronizer and coordinator (SAC) coupled with the CNTDand CNTD, the SAC including a required resources determinator, for determining the required resources of both networks for the next transmission cycle and for providing the required resources of one network to the other, wherein the master device of one network allocates resources to the other network and vice-versa.

Multi-network type coordinator for a single physical layer

A method for a network device of a powerline communications network includes selecting between a default preamble signal and a network-specific preamble signal specific to the network but not to a neighboring network and transmitting at least user data in conjunction with the selected preamble signal. Another method for a network device of a powerline communications network includes tuning a sensor to detect network-specific preamble signals specific to the network but not to a neighboring network and receiving at least user data associated with the preamble signals.

Network-specific powerline transmissions

A power unit includes an AC/DC converter for converting VAC input to DC, a zero cross unit for modulating the AC/DC converter output to facilitate zero crossing detection based on the output, and a high pass filter (HPF) for filtering data signals, where the data signals are transmitted and received on the same medium from which the VAC input is received. A method for providing power and data signals from a single powerline source, including receiving incoming VAC in an external power unit, converting the incoming VAC to DC, modulating the DC in accordance with zero crossings from the incoming VAC, filtering the VAC to isolate high frequency data signals, where the data signals are transmitted and received on a same medium from which the incoming VAC is received, and providing the DC, modulated DC, and data signals to an embedded processing unit capable of processing the data signals.

Enhanced power supply unit for powerline networks

A method includes transmitting a next transmission after an inter-frame period after a previous transmission, wherein the inter-frame period is long enough to allow a return signal responding to the previous transmission. A network device includes a receiver to receive a transmission from a source device and a transmitter at least to transmit a return signal to the source device indicating successful receipt or lack thereof of the transmission during a return period forming part of an inter-frame period after the transmission.

After transmission return signal

A method for a central coordinator of a network includes transmitting an active media access plan (MAP) using at least a regional mask and a bit allocation table (BAT) associated with the regional mask and transmitting a default MAP using only a permanent mask and a BAT associated with the permanent mask. The default MAP includes at least regional mask information.

Method for coordinating the use of a physical layer between a first network and a second network sharing the physical layer, the first network including at least one device operating using a first network protocol, the second network including at least one device operating using a second network protocol different from the first network protocol, a device in the first network not communicating with a device in the second network, including the procedures of determining required resources of the first network, determining required resources of the second network, requesting the required resources of the first network from a master device of the second network, requesting the required resources of the second network from a master device of the first network, allocating resources to the first network, by the master device of the second network, and allocating resources to the second network by the master of the first network.
