    Abstract: Abstract A system is provided for adjusting power provided over a channel to a device. The system can include power sourcing equipment and a sub-system. The power sourcing equipment can provide power to a powered device via a channel. The sub system can determine an amount by which to increase the power based on a resistance of the channel. The power sourcing equipment or the powered device can adjust the power (or load) in response to a command from the sub-system. The sub-system can include at least one measurement device and a processor. The measurement device can measure an output voltage of the power sourcing equipment, an input voltage of the powered device, and a current on the channel. The processor can determine the resistance of the channel based on the output voltage, the input voltage, and the current. The processor can output a command specifying an increase or decrease in the level of power supplied by the power sourcing equipment.

    Abstract: Abstract Certain features relate to improving the link-fault tolerance in a distributed antenna system (DAS) by utilizing a series of synchronous Ethernet frames. A receiving remote unit or a head-end unit in the DAS can predict the start of incoming Ethernet frames based on frame information extracted from previously received Ethernet frames. For example, a remote unit can be configured to receive one or more Ethernet frames, each of the one or more Ethernet frames including a start-of-frame field. After a period of time corresponding to the frame repetition rate, the remote unit can search for an additional start-of-frame field, indicating the receipt of the next Ethernet frame. The remote unit can extract the payload data from the next Ethernet frame based on the predicted value for the additional start-of-frame field.

    Abstract: A telecommunications system is provided that includes a unit for communicating channelized digital baseband signals with remotely located units. The channelized digital baseband signals include call information for wireless communication. The unit includes a channelizer section and a transport section. The channelizer section can extract, per channel, the channelized digital baseband signals using channel filters and digital down-converters. The transport section can format the channelized digital baseband signals for transport together using a transport schedule unit for packetizing and packet scheduling the channelized digital baseband signals. A signal processing subsystem can control a gain of uplink digital baseband signals, independently, that are received from the remotely located units prior to summing the uplink digital baseband signals.

    Abstract: Abstract Certain aspects involve selectively combining uplink transmissions in a distributed antenna system ("DAS"). For example, a unit of the DAS can receive baseband uplink transmissions from remote units of the DAS via a first channel and a second channel. The unit can generate a first combined uplink signal by combining baseband uplink transmissions received from a first subset of the remote units via the first channel that include data for transmission to a base station. The unit can generate a second combined uplink signal that includes baseband uplink transmissions received from a second subset of the remote units via the second channel and excludes or attenuates baseband uplink transmissions that are received from the first subset of the remote units via the second channel and that lack data for transmission to the base station are excluded or attenuated. The unit can transmit the combined uplink signals to the base station.

For example, a remote unit can be configured to receive one or more Ethernet frames, each of the one or more Ethernet frames including a start-of- frame fie!d. After a period of time corresponding to the frame repetition rate, the remote unit can search for an additional start-of -frame field, indicating the receipt of the next Ethernet frame. The remote unit can extract the payload data from the next Ethernet frame based on the predicted value for the additional start-of-frame field.
