A TDD (Time Division Duplex) switching control apparatus in a DAS (Distributed Antenna System) is provided. The present disclosure in some embodiments provides an apparatus, in a TDD switching control of a distributed antenna system, for transmitting a switching signal by using correlation property between a PSS (Primary Synchronization Signal) and an SSS (Secondary Synchronization Signal) and a property of a matched filter.

TdDD switching control apparatus of the distributed antenna system

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.

Method and apparatus for programmable and configurable sector localization in distributed antenna system

Some embodiments of the present disclosure relate to an analog distributed antenna system, and its operating method, provided with an orthogonal frequency division multiplexing (OFDM) high-speed modem for use in transceiving control signals between a main unit and remote units in order to effectively control the remote units connected to the main unit.
