Abstract: Certain features relate to configuring a remote unit in a distributed antenna system (DAS) to switch between a baseband mode of operation and a measurement receiver mode of operation. In the baseband mode of operation, the remote unit can transmit a subset of baseband channels to a head-end unit or an extension unit of the DAS. The subset of baseband channels can carry wireless communication information. In the measurement receiver mode, the remote unit can transmit wideband data to the head-end unit or the extension unit of the DAS. The wideband data can include one or more of a measurement data for additional baseband channels other than the subset of baseband channels and information for use by the head-end unit to modify a configuration of the distributed antenna system.

Abstract: A system includes: a unit configured to communicate a modulated signal via a signal interface; and at least one additional unit configured to receive the modulated signal from the unit. The at least one additional unit includes circuitry configured to remove jitter from a recovered clock signal to generate a jitter reduced clock signal that tracks long-term drift in the modulated signal, wherein the at least one additional unit is configured to generate the recovered clock signal from the modulated signal.

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: 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: Method and apparatus for generating a jitter reduced clock signal from signal transmitted over a communication medium includes receiving, with high speed data interface circuitry, a modulated signal that includes a binary encoded data stream. A recovered clock signal is generated from the modulated signal and tracks the long-term drift in the modulated signal. A jitter reduced clock signal is generated by filtering the recovered clock signal with a filtering circuit having a bandwidth sufficient to remove jitter while allowing the jitter reduced clock signal to track the drift in the modulated signal.

Abstract: A method of controlling uplink signal power in a distributed antenna system includes monitoring a noise condition of an uplink signal path in the distributed antenna system and determining the noise contribution from the distributed antenna system that is presented to the base station. The receive noise floor of the base station is determined. The determined noise contribution and receive noise floor are unlisted. Based on the evaluation, the uplink gain that is applied to uplink signals from the distributed antenna system to a base station is adjusted.
