(EN) SYSTEMS AND METHODS FOR A PASSIVE-ACTIVE DISTRIBUTED ANTENNA ARCHITECTURE
(FR) SYSTÈMES ET PROCÉDÉS POUR UNE ARCHITECTURE D'ANTENNES DISTRIBUÉES PASSIVE-ACTIVE
Abstract
(EN)
Systems and methods for a passive-active distributed antenna architecture are provided. In one example embodiment, a distributed antenna architecture comprises : a passive wireless coverage system in communication with a base station; an active wireless coverage system in communication with the base station; a conductor network comprising a plurality of cables coupled to at least one splitter-combiner device; and a DC power injector circuit coupled to the conductor network; wherein the DC power injector circuit injects a DC power signal onto the conductor network; wherein the passive wireless coverage system communicates analog radio frequency (RF) signals with the base station over the conductor network.
