    Abstract: Certain aspects involve a wideband remote unit. The wideband remote unit can include one or more antennas and an analog-to-digital converter (“ADC”). The antenna can receive wideband signals. The wideband signals can include an uplink RF signal and a leaked downlink RF signal. The uplink RF signal can have an uplink signal power at or near a noise level. The leaked downlink RF signal can have a downlink signal power greater than the uplink signal power. The ADC can convert the received wideband signals to digital RF signals representing the uplink signal and the downlink signal. The wideband remote unit can transmit the digital RF signals to a unit of a DAS that is in communication with a base station.

    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: Embodiments are disclosed for extracting sub-bands of interest from signals in a frequency domain for transmission via a distributed antenna system. In one aspect, a transformed downlink signal is generated by performing a frequency transform on a downlink signal. The transformed downlink signal represents the downlink signal in a frequency domain. At least one sub-band of the transformed downlink signal is identified as including data to be transmitted via the distributed antenna system. The sub-band is extracted from the transformed downlink signal for transmission via the distributed antenna system.

    Abstract: Systems and methods for optimized telecommunications distribution are provided. For example, a distributed antenna system can include a master unit for transceiving signals with remote units operable for wirelessly transceiving signals with mobile devices in a coverage area. A self-optimized network analyzer can be in a unit of the distributed antenna system. A self-optimized network controller in the distributed antenna system can output commands for changing operation of a component in the distributed antenna system in response to analysis results from the self-optimized network analyzer. In some aspects, the master unit includes base transceiver station cards for receiving call information in network protocol data from a network and for generating digital signals including the call information from the network protocol data for distribution to the remote units.

    Abstract: A telecommunications system is provided that can re-sample a digitized signal at a resample rate that is based on one or more factors to better utilize bandwidth. The factors can include the bandwidth of the signal that the digitized signal represents, the amount of bandwidth owned or used by the carrier, the full bandwidth of the designated RF band, the bandwidth of the serial link, the frame length of the serial link, the segmentation of the frames on the serial link, and the capability of the equipment at the receiving end of a serial link. The re-sampled signal can be transmitted to another unit that is remote to the unit transmitting the signal. The other unit can include a re-sampling device that restores the re-sampled signal to a digital signal that can be converted to an analog signal for wireless transmission.
