1. An open radio access network to provide wireless coverage for a plurality of cells at a site, the open radio access network comprising:
a virtualized headend comprising one or more base-station nodes; and
a plurality of unified remote units deployed at the site, each of which is associated with one or more antennas to wirelessly transmit and receive downlink and uplink radio frequency (RF) signals to and from user equipment;
wherein the plurality of unified remote units is configured to communicate with the one or more base-station nodes using a switched Ethernet network; and
wherein each unified remote unit comprises multiple downlink processing signal paths, multiple uplink processing signal paths, multiple downlink radio signal paths, and multiple uplink radio signal paths configured to support multiple fronthaul splits, multiple wireless interface protocols, multiple generations of radio access technology, and multiple frequency bands.
