The present disclosure in some embodiments relates to an automatic configuration tool to configure and install a distributed antenna system and an installation guide using the same. According to an aspect of the present disclosure, a user or a designer is graphically provided with a user interface to define a shape of the distributed antenna system, and is provided with a configuration tool for generating a configuration file for a configuration of an actual distributed antenna system. According to another aspect of the present disclosure, there is suggested a distributed antenna system for providing an installation guide function by using a configuration file generated in the configuration tool.

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.

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.
