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.
