    The Demand for DAS Systems in a 5G World

    In our modern world, filled with vast concrete buildings and countless cellular devices, the demand for DAS (Distributed Antenna Systems) has never been higher. As we transition from 4G to 5G, our digital landscape evolves, demanding seamless wireless connectivity that transcends structural and technological barriers.

    Distributed Antenna Systems are pivotal in supporting multi-band, multi-technology carriers across vast areas with minimal hardware—essentially, a signal source at one end and a distribution system at the other. DAS Solutions have diversified into several forms, including:

    • Off-Air Passive DAS
    • Off-Air Hybrid DAS
    • Small Cell Active DAS
    • Small Cell Hybrid DAS
    • BTS Active DAS
    • BTS Hybrid DAS

    Active and Passive DAS remains foundational, serving as the cornerstone for all variants.

    Exploring Active DAS Architecture

    In this blog, we will delve deeper into the architecture of an active DAS, examining its components, explaining why it's ideal for indoor wireless solutions, and exploring its benefits in enhancing capacity and coverage in large-scale public venues like airports and stadiums.

    Active DAS components

     

    Understanding Active DAS

    Active DAS operates as a network of distributed antenna-equipped radio units servicing both indoor and outdoor environments. It features diverse signal sources linked to a head-end unit, which in turn serves multi-band radio units. Active gain elements in both uplink and downlink directions distinguish active DAS systems.

    Five Key Components of Active DAS

    Component Description
    Signal Sources An active DAS is robust, yet it relies on external sources for its signals. These signals come from various sources like service provider feeds, Node-Bs, and small cells, all housed in the head-end equipment room. This setup allows multiple service providers to contribute their signals, creating a versatile multi-carrier active distributed antenna system.
    POI Tray

    Positioned between signal sources and the head-end unit, it consolidates RF signals, managing downlink signals often powered at 40 W to prevent excessive power loss and heat buildup.
    Head-End Unit

    Located in the equipment room, it connects to the POI using band-specific RF modules and coaxial cables. It enhances signals by filtering and amplifying based on frequencies, facilitating zone-wise signal distribution.
    Radio Units Receive, sort by frequency, amplify, and transmit signals via antennas. These units vary by transmission power and supported frequencies, powered by AC or DC sources.
    Fibre Optic Cables Essential for linking all DAS components, these cables are thin, flexible, and lightweight, minimizing signal loss. They support Single-Mode (SM) or Multi-Mode (MM) options based on signal type and transmission needs.

     

    Understanding these components highlights how Active DAS powers wireless networks in environments like airports or shopping complexes, ensuring seamless communication despite structural challenges.

    These components are essential for the proper functioning of an Active DAS network, enabling it to distribute wireless signals effectively across indoor or outdoor spaces. Each component plays a crucial role in signal transmission, amplification, distribution, and connectivity within the DAS infrastructure.
