Digital capacity centric distributed antenna system

Abstract

Disclosed herein is an architecture for a Digital Capacity Centric Distributed Antenna System (DCC-DAS) that dynamically manages and distributes resources in different locations where there is demand for capacity. The DCC-DAS also allows for the routing of resources to other applications such as location finding devices, jamming devices, repeaters, etc.
