  • Patent number: 9871163
    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.
