Abstract: A transceiver, a communication system and an associated method thereof for reducing overall power consumption and complexity of the transceiver that operates over short reach twisted pair cables. The analog front end (AFE) of the transceiver communicates over at least one twisted pair that is configured only for transmission of data streams and communicates over at least one twisted pair that is only for reception of data streams. The transceiver includes circuitry that generates multiplexed and demultiplexed data streams for communication with the analog front end. Additionally, the transceiver utilizes at least certain portions of signal processing circuitry and AFE of a 10 GBASE-T transceiver or the like.

Abstract: In a satellite gateway, data is transmitted over a downstream channel at different throughput rates. Data destined for each subscriber/receiver is assigned a throughput rate depending upon the downstream signal quality of that subscriber/receiver. The downstream data is parsed to extract data packets. The data packets are then loaded into packet queues based on an identifier within such packets. The queues represent a bandwidth efficiency or throughput rate that can be currently tolerated by specific subscribers that may also be based on the current signal quality at a subscriber location. The parsed data traffic is processed based on the profile of the plurality of profiles to produce processed data traffic, and transmitted from the packet queues over a downstream channel.

Abstract: An apparatus for operating a low data-rate (LDR) link and legacy switch at a high data-rate (HDR) includes a first block and a second block. The first block receives input signals from the legacy switch and generates identical output signals. The second block receives the identical output signals and generates an HDR signal for communication over the LDR link coupled to an access point. Further, a media access control (MAC) interface communicates data at a first data rate with an Ethernet PHY block including a first-in-first-out (FIFO) module and a buffer. The FIFO receives data from the MAC interface at the first data rate and transmits data at a second data rate. The buffer receives data from the Ethernet port at the second data rate and transmits the received data at the first data rate in response to detection of an end of packet.

Abstract: Disclosed are method and system for Ethernet media conversion supporting high-speed wireless access points. The method includes receiving at each of a plurality of input-side Ethernet modules in a media converter, a plurality of input data streams at a first data rate. In the media converter each of the plurality of input data streams may be aggregated into an output data stream at a second data rate. The output data stream may then be transmitted at the second data rate from an output-side Ethernet module in the media converter. Each of the input data streams may be received from an Ethernet switch, and the output data stream may be transmitted to a wireless access point. In one exemplary implementation, each of the input-side Ethernet modules may include a 1G PHY, while the output-side Ethernet module may include one or both of a 2.5G PHY and a 4G PHY.
