1. A system comprising:

  • a hub unit configured to receive a plurality of downlink radio frequency (RF) carriers from a plurality of base stations via a plurality of analog downlink signals;

    a plurality of radio access nodes, each of the plurality of radio access nodes located remotely from the hub unit and communicatively coupled to the hub unit;

    wherein the hub unit comprises a plurality of analog-to-digital converters to produce digital versions of the analog downlink signals;

    wherein the hub unit is configured to generate downlink digital data indicative of the downlink RF carriers using a plurality of channelizers;

    wherein the hub unit is configured to generate the downlink digital data from the digital versions of the analog downlink signals;

    wherein the hub unit is reconfigurable to selectively provide, to each of the plurality of radio access nodes, the downlink digital data associated with a respective two or more of the downlink RF carriers; and

    wherein each of the plurality of radio access nodes is configured to generate, from the downlink digital data provided to that radio access node, a plurality of analog downlink RF signals using a plurality of digital-to-analog converters, wherein the plurality of analog downlink RF signals comprises the two or more downlink RF carriers associated with the downlink digital data provided to that radio access node, wherein that radio access node radiates the plurality of analog downlink RF signals in a respective coverage area associated with that radio access node.
