Coverage Where You Need It

Distributed Antenna Systems (DAS) FAQs

Choosing the right Distributed Antenna System involves more than improving signal strength. Explore answers to common questions about DAS design, coverage, installation, public safety, and long-term performance.

• What is a Distributed Antenna System (DAS)?

  A Distributed Antenna System (DAS) is a network of antennas that distributes cellular and public safety radio signals throughout a building. It improves wireless coverage in areas where traditional signals are weak or unavailable.

• When does a building need a DAS?

  Buildings with poor indoor cellular reception, dense construction materials, underground spaces, or public safety radio requirements often benefit from a DAS. Large facilities such as hospitals, warehouses, manufacturing plants, schools, stadiums, and office buildings are common candidates.

• What's the difference between DAS and cellular boosters?

  Signal boosters amplify an existing cellular signal and are best suited for smaller spaces. DAS solutions distribute wireless coverage throughout larger or more complex facilities and can support multiple carriers and public safety communications.

• Can DAS improve public safety communications?

  Yes. Public safety DAS solutions, often referred to as ERRCS (Emergency Responder Radio Coverage Systems), help extend emergency radio coverage throughout a building, supporting first responders during critical events. Requirements vary based on local codes, NFPA and IFC standards, and AHJ approval.

• Will DAS work with all cellular carriers?

  Many DAS solutions are designed to support multiple wireless carriers, although the specific carriers supported depend on the system design and carrier participation. We evaluate your facility's requirements to recommend the right solution.
  

• How is a DAS designed?

  Every DAS begins with an assessment of your building's size, construction materials, occupancy, and existing wireless coverage. That information is used to engineer a system that delivers reliable coverage where it's needed most.

• Does a DAS require ongoing maintenance?

  Like any critical building system, a DAS should be periodically inspected and tested to verify performance. Ongoing maintenance helps ensure reliable coverage as your facility and wireless needs evolve.
  

• Can a DAS be installed in an existing building?

  Yes. DAS solutions can be deployed in both new construction and existing facilities. The installation approach depends on your building's layout, infrastructure, and operational requirements to minimize disruption.
