A Distributed Antenna System (DAS) is a network of antennas that helps spread mobile coverage throughout buildings or large areas.
Whether it’s a small setup with just a few antennas or a network of hundreds, the design depends on the system size and how it connects to the mobile network. That might mean using a mobile repeater, or connecting directly to a mobile carrier’s Base Transceiver Station (BTS).
In Australia, DAS systems are typically designed to support multiple carriers like the monoliths of Telstra, Optus, and TPG (Vodafone) based on Mobile Carriers Forum (MCF) standards. Even smaller DAS installations that use repeaters can be designed to support all three carriers if installed correctly. That’s why it’s important to engage a qualified DAS design team early in the process, like Digicom Wireless.
You might hear terms like Passive DAS, Active DAS, and Hybrid DAS – but what do they mean? Here’s a quick deepdive into each: :
- Passive DAS uses “Passive” coaxial cables and splitters, so no power is needed at the antenna end.
- Active DAS uses a central unit to convert RF signals into fibre or Ethernet, sending them to “Active” powered antennas that convert the signal back to RF.
- Hybrid DAS combines both methods using high-power fibre remotes to deliver signal over fibre, which then feeds passive coaxial cables and splitters for flexible distribution.
Key Takeaways
- A DAS is the antenna system that distributes mobile signals indoors.
- Systems can be passive, hybrid, or active depending on size, layout, and coverage goals.
- The signal source could be a mobile repeater or a Base Transceiver Station (BTS) – your system size usually decides which.
