Distributed Antenna System And Method
View pageUS Patent:
20130236180, Sep 12, 2013
Filed:
Aug 17, 2012
Appl. No.:
13/588717
Inventors:
Bung Chul Kim - Burbank CA, US
Younghoon Ko - Burbank CA, US
Younghoon Ko - Burbank CA, US
International Classification:
H04J 14/02
H04B 10/12
H04B 10/12
US Classification:
398 72, 398115
Abstract:
A distributed antenna system includes a plurality of remote units configured to service different regions of a service area, and a head-end unit configured to process and transmit downlink signals from base stations to the remote units over optical cables, and to process and transmit uplink signals from the remote units to the base stations, wherein the remote units are configured to adjust or filter a level of downlink signals from the head-end unit and to transmit the adjusted or filtered downlink signals to mobile stations, and to process and transmit uplink signals from mobile stations to the head-end unit over the optical cables.

Abstract:
An apparatus for implementing an adaptive sectorization in a DAS (Distributed Antenna System) is provided. In some embodiment of the present disclosure, a DAS that supports an adaptive sectorization has the flexibility of supporting multiple sectors simply with an extension of STM (Sectorization Module) without being affected by the hardware structure. Where no sector splitting is needed, the STM is replaced by a COM (Head-end Combining Module) to provide a simple structure for supporting the sectors.
