    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 (302). The sub-system can determine an amount by which to increase the power based on a resistance of the channel (306). 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 (304). The processor can determine the resistance of the channel based on the output voltage, the input voltage, and the current (306). The processor can output a command specifying an increase or decrease in the level of power supplied by the power sourcing equipment.

    Abstract: Certain features relate to operating a distributed antenna system or repeater system communicating frequency-division duplexing ("FDD") signals in a time-division duplexing ("TDD") mode. A TDD mode scheduler is configured for monitoring a downlink communications channel for the start of a downlink frame, sub-frame, or resource slot. Based on the start of a downlink frame, sub-frame, or resource slot, the TDD mode scheduler can identify a TDD transmission time-slot. The TDD mode scheduler can schedule high-powered downlink sub-frames during the TDD transmission time-slots where higher power output may be desirable. Based on the indication of the TDD transmission time-slot, a transmit/receive controller can increase the gain of the downlink communication and reduce the gain of the uplink communication.

    Abstract: Systems and methods for developing a configuration plan for communication transport links of a distributed antenna system are provided. The distributed antenna system includes a unit communicating with remote antenna units over the communication transport links. The unit receives signals from base stations. Characteristics of each of the signals are determined. The characteristics include, for each signal, a frequency occupancy, a digital bandwidth, and a coverage zone to which to provide the signal. The frequency occupancy includes the minimum frequency component and the maximum frequency component of the signal. The digital bandwidth is a bandwidth for communicating the signal via the communication transport links. A hardware capability of the distributed antenna system, such as a respective available bandwidth for each communication transport link, is also determined. The configuration plan for transporting the digital representations of the signals is determined based on the hardware capability and the characteristics of the signals.

    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.
