A BCN network with BCN modems that enable network wired devices to communicate over a typical home coaxial network that may include passive splitters and different types of coaxial cable.

Broadband local area network

A network for determining a common bit-loading modulation scheme for communicating between nodes in the network is disclosed. The network may include a transmitting node within the plurality of nodes where the transmitting node is capable of sending a probe signal to the nodes, and at least one receiving node within the plurality of nodes in signal communication with the transmitting node. The at least one receiving node is capable of transmitting a first response signal in response to receiving the probe signal. The first response signal includes a first bit-loading modulation scheme determined by the at least one receiving node. The transmitting node is further capable of determining the common bit-loading modulation scheme from the first response signal.

Broadband cable network utilizing common bit-loading

A broadband cable network ('BCN') for determining a common bit-loading modulation scheme for communicating between a plurality of nodes in the BCN is disclosed. The BCN may include a transmitting node within the plurality of nodes where the transmitting node is capable of sending a probe signal to the plurality of nodes, and at least one receiving node within the plurality of nodes in signal communication with the transmitting node. The at least one receiving node is capable of transmitting a first response signal in response to receiving the probe signal. The first response signal includes a first bit-loading modulation scheme determined by the at least one receiving node. The transmitting node is further capable of determining the common bit-loading modulation scheme from the first response signal.

A BCN network with BCN modems that communicate using predefined messages to establish, optimize and facilitate data communication.

Multimedia over coaxial cable access protocol

A physical layer transmitter that communicates between nodes in a broadband cable network by transmitting and receiving packets containing data and control information. Packets are constructed by the physical layer transmitter and transmitted to one or more receiving nodes that are capable of processing the packets. Packets are directed to specific nodes utilizing link layer control data. The packets may also contain control information that may include formatting, encoding and modulation parameters that are capable of being processed by the appropriate receiving nodes. The physical layer transmitter allows node-to-node communication within a broadband cable network and each node in the network is capable of communicating with every other node in the network.

Physical layer transmitter for use in a broadband local area network

A broadband local area data network uses coaxial cable wiring for interconnection of terminal devices. Orthogonal frequency division multiplexing (OFDM) with bit loading is used to overcome channel impairments and provide a path for terminal devices to transmit to and receive from other terminal devices. Probe messages are sent between devices to characterize the communication channel and determine optimum bit loading. The data network shares the cable spectrum with other services and uses frequency bands not used by other services. Adaptive power control can be used to maintain signal to noise ratio in a communication between terminal devices. Frequency coordination can be used to avoid interference between the LAN communications and other services transmitted on the cable.

Broadband network for coaxial cable using multi-carrier modulation

A local area network uses coaxial cable wiring for interconnection of terminal devices. A frequency selective network interface device is placed at the building point of entry or another point in the wiring to reflect network signals transmitted by terminal devices back into the building distribution to be received by other terminal devices. By reflecting network upstream signals back into the building as downstream signals, the network interface provides a path for terminal devices to transmit to and receive from other terminal devices.
