Abstract
An open access signal distribution system in which a variety of wireless voice, data and other services and applications are supported. The open access system 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 amoung 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.
