Abstract
A broadband over powerline (BPL) master control unit is provided. The BPL master control unit includes a processor, a local memory device, a first wireless transceiver, a second wireless transceiver and a powerline transceiver. The processor is configured to transmit and receive data over a power line via the powerline transceiver. The processor is further configured to receive a plurality of data via the powerline transceiver, determine whether to route the plurality of data through the first wireless transceiver or the second wireless transceiver, and transmit the plurality of data via one of the first wireless transceiver and the second wireless transceiver based on the determination.
Claims19
A broadband over powerline (BPL) master control unit comprising:
- a processor;
- a local memory device in communication with the processor;
- a first wireless transceiver in communication with the processor;
- a second wireless transceiver in communication with the processor;
- and
- a powerline transceiver in communication with the processor,
- wherein the processor is configured to transmit and receive data over a power line via the powerline transceiver, and wherein the processor is further configured to:
- receive a plurality of data via the powerline transceiver;
- determine a first signal strength of the first wireless transceiver;
- determine a second signal strength of the second wireless transceiver;
- compare the first signal strength and the second signal strength;
- determine whether to route the plurality of data through the first wireless transceiver or the second wireless transceiver based on the comparison;
- and
- transmit the plurality of data via one of the first wireless transceiver and the second wireless transceiver based on the determination.
A BPL slave unit comprising:
- a processor;
- a local memory device in communication with the processor;
- a removable storage device in communication with the processor;
- and
- a powerline transceiver in communication with the processor,
- wherein the processor is configured to transmit and receive data over a power line via the powerline transceiver, wherein the processor is in communication with a plurality of systems, and wherein the processor is further configured to:
- receive a plurality of data from the plurality of systems;
- determine whether or not the powerline transceiver is connected to a BPL master control unit;
- transmit, via the powerline transceiver, the plurality of data to the BPL master control unit if the powerline transceiver is connected to the BPL master control unit;
- and
- store, in the removable storage device, the plurality of data if the powerline transceiver is not connected to the BPL master control unit.
A method for communicating via a BPL connection, the method implemented by a master control unit including a processor in communication with a memory, the method comprising:
- detecting, via the BPL connection, a connection to a slave unit;
- receiving, via the BPL connection, a plurality of data from the slave unit;
- determining a destination for the plurality of data;
- comparing two or more transmission methods for transmitting the plurality of data to the destination;
- and
- transmitting the plurality of data to the destination via one of the two or more transmission methods based on the comparison.
