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.

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: One embodiment is directed to a universal digital card (UDC) for use in a node of a distributed antenna system (DAS). The UDC is configured to convert data between an external interface format used to communicate on an external communication link and a fronthaul interface format natively used in the DAS. The UDC is configured to be selectively used either as: a donor card to communicatively couple the node to one or more base station entities via the external digital interface or a distribution card to communicatively couple the node to one or more non-DAS nodes, hubs, switches, or remote radio heads or one or more other DAS nodes access points. Other embodiments are disclosed.

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: One embodiment is directed to an open radio access network (O-RAN) distributed antenna system (DAS) that comprises a central access node (CAN) configured to communicatively couple at least one O-RAN distributed unit (O-DU) to the O-RAN DAS, where the O-DU is configured to communicate with a single O-RAN remote unit (O-RU) entity. The O-RAN DAS also includes a plurality of O-RAN remote units (O-RUs) communicatively coupled to the CAN over a fronthaul network, where the O-DU, CAN, and O-RUs are configured to natively use an O-RAN fronthaul interface to communicate fronthaul data over the fronthaul network. The CAN is configured to appear to the O-DU as the single O-RU entity for a cell served by the O-DU even though the CAN is configured to serve the cell using multiple O-RUs that form a simulcast group for that cell. One or more CANs can be used. Other embodiments are disclosed.

Abstract: An interface is provided for processing digital signals in a standardized format in a distributed antenna system. One example includes a unit disposed in a distributed antenna system. The unit includes an interface section and an output section. The interface section is configured for outputting a first complex digital signal and a second complex digital signal. The first complex digital signal is generated from a digital signal in a standardized format received from a digital base station. The output section is configured for combining the first complex digital signal and the second complex digital signal into a combined digital signal. The output section is also configured for outputting the combined digital signal. The combined digital signal comprises information to be wirelessly transmitted to a wireless user device.
