Active systems ensure optimised signal strength and uniform distribution.

Applications

DAS systems excel in environments where consistent indoor coverage is essential:

  • Commercial Buildings
    Ensuring smooth communication for employees and clients.
  • Hospitals
    Providing life-critical connectivity for healthcare staff and devices.
  • Shopping Centres
    Supporting shoppers and businesses with robust signals.
  • Transport Hubs
    Delivering reliable connections in airports, train stations, and bus depots.

What is Traditional DAS?

Traditional coaxial DAS are designed to enhance cellular signal coverage in large or complex environments, such as office buildings or stadiums. The system uses a central unit, typically a base station, that connects to multiple antennas distributed throughout the space. These antennas are connected to the central unit via coaxial cables, which carry the radio frequency (RF) signals between the source and the antenna locations. The antennas help to evenly distribute cellular signals, ensuring that mobile devices receive strong coverage even in areas with poor signal penetration.

Coaxial DAS relies on a centralised architecture where the signal is sent through the coaxial cable to each antenna, often resulting in significant cable runs and a more complex installation process. The system typically requires a large amount of hardware, including repeaters, splitters, and amplifiers, which can drive up costs and require more physical space for installation. The use of coaxial cables also limits scalability and flexibility in future upgrades, making it less efficient for expanding coverage in rapidly evolving environments compared to newer, more modular systems like fibre-based DAS.

DAS installations can be done in greenfield (new) and brownfield (existing) buildings. When approaching a DAS project, it is important to consider the building and the current technology available to complete the project.

FAQs

Have questions about DAS? We have the answers.

A Passive DAS distributes signals using coaxial cables, splitters, and antennas. It requires careful design to balance signal strength and minimise loss. In contrast, an Active DAS transmits signals via fibre and Ethernet to remote radio units, offering more flexibility in large or complex buildings. While Active DAS provides superior scalability, it is generally more expensive than Passive DAS.
High Power Active DAS employs fewer but larger remote units to cover extensive areas, making it well-suited for stadiums, campuses, and major commercial precincts. Low Power Active DAS, like the Ericsson Radio Dot System, is designed for in-building use, using compact remote units that provide an efficient and cost-effective solution for office spaces, hospitals, and hotels.
A DAS is deployed in various settings, including commercial offices, high-rises, hospitals, shopping centres, hotels, stadiums, underground car parks, and tunnels. The system ensures seamless mobile connectivity where natural signal penetration is weak or inconsistent. Where a building is not a good candidate for a DAS, a Cellular Repeater system might be a great option.
The process begins with a coverage assessment to identify weak signal areas and carrier requirements. A site survey follows, mapping out an optimal DAS design. Once carrier engagement and approvals are obtained, installation planning takes place, outlining cabling pathways and power needs. The final steps involve procuring necessary equipment and completing the installation and commissioning phase to ensure optimal performance.
The MCF Standard establishes guidelines for designing, deploying, and approving in-building mobile coverage solutions. The upcoming MCF 2025 standard aims to enhance carrier approval processes, improve system interoperability, and set clearer technical benchmarks for DAS and small cell installations in Australia. Compliance with these updated standards is expected to be a requirement for carrier-approved DAS projects in the near future.
