1. A system for distributing radio frequency signals in a physical area in which multiple wireless service providers wish to provide service, the system comprising:

  • a first plurality of wireless base stations collocated at a hub location, the base stations receiving and transmitted radio frequency signals, with at least two of such base stations operating with radio frequency signals according to two different air interfaces;

    a base station interface, also located at the hub, for converting the radio frequency signals associated with the base stations to and from a transport signaling format;

    a shared transport medium, for transporting the converted signals from the hub location to a plurality of remote access node locations;

    a plurality of radio access nodes located at the remote access node locations, the radio access nodes each associated with a partial coverage area corresponding to only a portion of a total system coverage area, and the radio access nodes connected to the transport medium; and

    the radio access nodes further each comprising;

    a plurality of slice modules, with each slice module containing equipment for converting received radio frequency signals formatting according to a selected one of the air interfaces to the transport signal format and from the transport signal format to the selected one of the air interfaces.
