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: 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: Certain aspects and aspects of the present invention are directed to a distributed antenna system having a downlink communication path, an uplink communication path, and a non-duplexer isolator sub-system. The downlink communication path can communicatively couple a transmit antenna to a base station. The uplink communication path can communicatively couple a receive antenna to the base station. In one aspect, the non-duplexer isolator sub-system can be electronically configured for isolating uplink signals traversing the uplink communication path from downlink signals. In another aspect, a non-duplexer isolator sub-system can be configurable in one or more mechanical steps selecting a frequency response. In another aspect, a non-duplexer isolator sub-system can include an active mitigation sub-system.

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: 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.
