Safety and communication go hand in hand. You can improve both at the same time with a distributed antenna system. If you manage a building, you should know the best practices for distributed antenna system design, so you can choose the right one for your space. Read about five different types to consider.

Active DAS

With an active distributed antenna system (DAS) design, you can use the same cables as you do for your internet. This involves a unit that grabs signals from nearby towers and distributes them through your building via ethernet and fiber optic cables. The signal is amplified by nodes or active antennas, so you don’t lose coverage when inside your building.

Passive DAS

A passive DAS uses coaxial cables, splitters, and couplers. The further you are from an antenna, the weaker your signal. Many people prefer passive DAS because it’s cheaper to install and maintain.

Hybrid DAS

Hybrid DAS also tends to cost less than active due to the number of nodes needed. The design combines passive and active systems, so both coaxial and fiber optic cables support your signal. The system doesn’t limit where you can increase frequencies on your campus.

Digital DAS

While most systems convert radio frequencies to analog, you can choose to convert them digitally. It’s more expensive, but offers a clearer signal. Plus, this system is less likely to encounter interference, meaning your signal will stay strong in heavy winds and rain.

Public Safety DAS

Some areas require a public safety DAS if you want to operate a business or building. The system helps first responders stay connected if there’s a crisis on your property. To achieve a properly functioning public safety system, it must meet the following requirements:

  • Cables must meet a two-hour fire rating
  • You must house equipment in a NEMA-4 compliant enclosure
  • You must use a battery backup
  • Must maintain a signal strength of at least -95 dBm
  • Must cover 90 to 99 percent of your property

Know the best practices for distributed antenna system design and pick the one your building needs. Passive and hybrid systems give you a wider range of coverage, while active DAS is the best at strengthening a signal. You can also digitize to improve your experience. Hire distributed antenna system companies, such as Harris Communications, to help you get started today.
