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: Telecommunication systems using multiple Nyquist zone operations are provided. In one aspect, a telecommunication system can include a first section and a second section. The first section can receive signals from at least one transmitting base station or transmitting terminal device. The received signals have frequencies in multiple frequency bands. The first section can also sample the received signals such that the received signals are aliased. The first section can also combine the aliased signals from the frequency bands into a combined frequency band in a common Nyquist zone. The second section can extract signals from the combined frequency band. The extracted signals are to be transmitted at frequencies in a frequency band from a Nyquist zone that is different than the common Nyquist zone. The second section can also transmit the extracted signals to at least one receiving base station or receiving terminal device. Other embodiments are disclosed.

Abstract: A user interface for a distributed antenna system (DAS) is provided. When executed by a processor, a signal distribution engine receives information about signals transported by the DAS and components of the DAS. The signal engine generates a signal set assignment user interface including a list of signals transported by the DAS and a signal set formation area for receiving a signal set. The signal engine also generates a signal distribution user interface that includes representations of signal sets, hardware components, and associations between hardware components. In response to receiving a request to associate the signal set with a specified hardware component, a command is output to configure a signal path so that signals in the signal set are provided to the specified hardware component.

Abstract: The present disclosure relates to transport link quality measurement in a distributed antenna system. A link quality indicator associated with the functional performance of a digital transport link in the distributed antenna system can be determined by a component of the distributed antenna system. An indication of a potential fault condition can be determined based on the link quality indicator before a fault condition associated with the potential fault condition occurs. The indication of the potential fault condition can be presented, for example, via a graphical user interface, a table, or an email alert.

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: Certain features relate to unequal distribution of transmitters and receivers in a distributed antenna system (DAS). Remote units in the DAS can be configured as transmitting remote units, receiving remote units, or remote transceiver units that can transmit and receive wireless signals. In some configurations, the DAS can be configured with a greater number of transmitting remote units than receiving remote units. In other configurations, the DAS can be configured with a greater number of receiving remote units. In some aspects, unequal distribution of transmitters and receivers can be obtained by allocation of transmission frequencies and receiver frequencies in the DAS.
