Abstract: The present home networking method and system is based on the IEEE 802.11 wireless networking standard expanded to encompass home phone line media communication and/or home power line media communication operation seamlessly. For each station in home network (i.e., wireless, phone line and power line), the protocol stack at the PHY layer and above, QoS, and network security are all based on the 802.11 standard. Chipset implementations differ in an applied analog interface that is specific to the respective medium. Station-to-station transmission between wireless and wired terminals is enabled via an intelligent access point which includes an analog interface for each of the medium types. Further, each station can be configured with the appropriate analog interface to communicate directly with any wireless station. The access point is also expandable to form extended service sets.

Abstract: A telecommunications system using DSL modems (36, 38) detects on-hook or off-hook states of a local loop telecommunications line (18). If the local loop (18) is in an off-hook state, the normal data communication rates are used. If the local loop is in an on-hook state, the unused voice band is allocated to either the upstream band and/or downstream band of the DSL modems, in order to increase data communication rates.

Abstract: A method and system for controlling data latency in a communication network use a pre-selected portion of the data to identify one of at least two latency paths. The data is transported to a network device (500) through physical channel (502). The network device (500) includes at least two latency paths (506,508), each operable to transport the data through to other parts of the device (500) at an associated rate. In a first aspect of the present invention, data sorter (504) extracts a latency path identifier from the incoming data then provides the incoming data to one of the at least two latency paths (506,508) accordingly. In another aspect of the present invention, the data sorter (504) extracts a indicator from the incoming data which characterizes the incoming data, decodes the indicator to determine which of the at least two latency paths (506,508) to selects, then provides the incoming data to the selected one of the at least two latency paths (506,508).

Abstract: A modem communication system with receiving and transmission paths includes a direct equalizer system having an adaptive filter (1532) in the transmission path to compensate for frequency distortion of the communication channel. The transmitter filter coefficients are adapted by a filter coefficient calculator (1528), under control of a data detector (1526) which detects incoming data in the receiving path. A switch (1534) is controlled by status of a transmit output data buffer to multiplex either the training sequence or output data into the transmission path. When the buffer is idle, the training sequence generator (1540) is linked to a digital-to-analog (D/A) converter (1536) and line driver (1538). The receiving path includes an isolation switch (1520), a receiver amplifier (1522) and a slicer (1524). The receiver correlates the received training sequence with a known training sequence and updates the equalizer filter coefficients using an adaptation algorithm, such as a least mean squared algorithm.
