Multi-protocol distributed wireless system architecture
First Claim
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.

Abstract
A open access signal distribution system in which a variety of wireless voice, data and other services and applications are supported. The open access systems makes use of a distributed Radio Frequency (RF) distribution network and associated network entities that enable the system operator to employ a wireless infrastructure network that may be easily shared among multiple wireless service providers in a given community. The open access system provides the ability for such operators and service providers to share the infrastructure regardless of the specific RF air interface or other signal formatting and/or managing messaging formats that such operators choose to deploy.
