摘要： 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.

摘要： 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.

摘要： 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.
