Introduction
Distributed Antenna Systems (DAS) have become essential infrastructure for modern workplaces, enabling reliable mobile coverage, high data speeds, and seamless connectivity even in challenging environments. Australian businesses increasingly rely on robust in-building wireless solutions – making DAS critical for commercial buildings, hospitals, universities, hospitality venues, and large-scale facilities.
What is a Distributed Antenna System?
DAS is an integrated network of spatially-separated antennas connected to a common source, designed to enhance wireless signals indoors or across wide areas. Unlike single antenna solutions, DAS distributes RF signals via cabling and controllers, overcoming coverage gaps caused by concrete structures, metal beams, and other signal-blocking materials.
- Example Use Cases: Office towers, underground car parks, high-rise apartments, stadiums, hospitals.
How Does DAS Work in Australian Buildings?
DAS solutions involve strategically mapping out a facility’s wireless needs and positioning antennas to eliminate blackspots for mobile, Wi-Fi, or emergency services. Signals may come directly from telecommunications carriers, fibre, or local signal boosters:
- Head end equipment controls signal distribution
- Fibre or coaxial cables connect remote antennas
- Each antenna transmits wireless coverage to its zone
- The system integrates with building management and fire safety

Key Benefits for Australian Businesses
1. Reliable Mobile and Data Coverage
Businesses require uninterrupted mobile access for daily operations, client communications, staff safety, and emergency response. DAS ensures high-quality coverage for Telstra, Optus, Vodafone and carrier-agnostic networks.
2. Compliance & Safety
Regulations may mandate in-building wireless for emergency services (e.g., NSW planning requirements for fire safety communications). DAS supports compliance, fulfilling legal needs for commercial fitouts and public spaces.
3. Futureproofing Technology
DAS upgrades are scalable to accommodate 5G, IoT, and Wi-Fi advancements. Systems can adapt to tenant growth, technology refreshes, and evolving user demands without disruptive infrastructure works.

Types of DAS Solutions
Passive DAS
Passive DAS relies on coaxial cables, splitters, and couplers to distribute a wireless signal throughout the building, with no active (powered) components. This topology works well for small or medium-sized facilities where antennas and the signal source are relatively close. The upsides are low cost, minimal maintenance, and simple design—making it ideal for cost-conscious projects or straightforward layouts. Passive DAS systems are highly reliable, usually support a wide range of frequencies used by Australian mobile carriers, and can be expanded in future with basic hardware additions. However, signal degradation over long cable runs and limited capacity for complex, multi-storey buildings are drawbacks.
Active DAS
Active DAS uses powered equipment—such as remote radio units, amplifiers, and controllers—to boost, digitise, and manage wireless signals. Signals often travel between the source and antennas using optical fibre or Ethernet, which overcomes the distance restrictions of coaxial cabling and ensures strong, consistent coverage even in very large or architecturally complex buildings. Active DAS can be monitored remotely for troubleshooting and maintenance, offers the highest level of control, and integrates easily with advanced carrier networks and 5G services. Implementation costs and complexity are notably higher, and ongoing support may be needed for hardware, firmware, and system updates.
Hybrid DAS
Hybrid DAS systems combine elements of passive and active architectures for flexibility, performance, and cost control. Typically, hybrid DAS employs optical fibre or Ethernet “backbone” to transmit the signal over long distances to remote units (often on each floor), which then use passive coaxial cabling to distribute the signal locally. This design allows reliable, scalable coverage for medium to large buildings—eliminating the cable length restrictions of pure passive DAS, while reducing the number of expensive active components needed. Hybrid solutions are easier to retrofit in existing buildings and can be fine-tuned for various coverage needs. Installation is more complex, as it requires both fibre and coaxial management.
