Abstract: One embodiment is directed to a system to provide wireless coverage for a plurality of cells. The system comprises a virtualized headend and a plurality of remote units. The system is configured to operate as a distributed antenna system (DAS) when serving at least one of the cells. The plurality of remote units is configured to communicate with the virtualized headend using a switched Ethernet network. The virtualized headend is configured to communicate downlink user-plane data including frequency-domain IQ data and downlink control-plane data for a first cell served by at least one open radio access network (O-RAN) distributed unit (DU) to at least some of the remote units used to serve the first cell. At least some physical layer baseband processing for a wireless interface used to serve the first cell is performed by the virtualized headend or the remote units used to serve the first cell.

Abstract: Systems and methods for a modular access point are provided. In certain embodiments, a device includes a housing. Further, the device includes a baseband card (BBC) mounted within the housing, wherein the modular BBC has one or more interfaces. Additionally, the device includes one or more radio modules, wherein at least one radio module in the one or more radio modules is coupled to an interface in the one or more interfaces, wherein the one or more interfaces are capable of connecting to multiple different power classes of radio modules. Moreover, the device includes one or more additional components in communication with the modular BBC through the one or more interfaces that support the operation of a radio module in a respective power class.

Abstract: One embodiment is directed to an open radio access network to provide wireless coverage for a plurality of cells at a site and that comprises a virtualized headend comprising one or more base-station nodes and a plurality of unified remote units deployed at the site. Each of the unified remote units is able to support multiple functional splits, multiple wireless interface protocols, multiple generations of radio access technology, and multiple frequency bands. The unified remote units and functional split used to serve each cell can be changed (for example, on-the-fly as a part of an automatic or manual adaptation process that is a function of one or more monitored performance attributes of the open radio access network such as network bandwidth, network latency, processing load, or processing performance). The unified remote units can be implemented in a modular manner with a backplane to which different radio modules can be coupled.
