Title: LTE CONCENTRATOR AND DISTRIBUTOR SYSTEM AND METHOD FOR COVERAGE EXTENSION
Abstract:
A Long Term Evolution (LTE) Concentrator and Distributor system and method extends geographical coverage while minimizing Evolved Node B (eNB) deployments. The system and method use a distributed array of Wide Band Receiver Transmitter (WBRT) devices (i.e., RF Heads, RFH, including antennas) connected via wide-band links to a central standard LTE eNB through a novel LTE Concentrator-Distributor (LTE-CD) which is an uplink (smart optimal) concentrator and downlink simulcast distributor. The eNB downlink signal (baseband or modulated RF) is distributed in synchronization (simulcast) through the LTE-CD to all WBRTs for downlink simulcast transmission to all UEs in the coverage area. The WBRTs receive uplink signals from user equipment, UE, devices in a coverage area, send the uplink signals (baseband or modulated RF) to the LTE-CD which optimally combines all received signals into one best uplink signal that is sent (in baseband or modulated RF) to the eNB.
