What Is DAS?

DAS stands for distributed antenna system. DAS is used to provide enhanced cellular coverage where needed, accommodating heavily trafficked public areas, large events and even business networks.

How Does DAS Work?

These networks of antennas are distributed throughout a targeted area in order to improve performance of the network and provide additional cellular coverage. Strategic locations are selected for antenna installation, connected to a communications hub using fiber optic cable. This setup allows cellular signal processing by the cellular base station.

Distributed antenna systems consist of two key components: a signal source and a distribution system.

  • A DAS generally does not generate cellular signal; the system merely distributes it across an area. Therefore, the signal must be fed to the DAS from elsewhere. These sources typically include off-air from a roof antenna, onsite Base Transceiver System (BTS) or small cells.
  • Once the cellular signal is received, the DAS must distribute it throughout a space. Possible distribution systems include active with fiber optic or ethernet cable, passive, hybrid or digital.

The right type of distributed antenna system for an application depends on several factors. These include size, project time constrictions, signal quality and capacity versus coverage. 

Why Is DAS Needed?

Cellular signals are obstructed for a variety of reasons, including certain building materials, underground locations and even energy-efficiency building codes. Low-E windows and concrete walls designed to reduce energy loss in a facility are common blockers of cellular signals. When the signals coming from area cellular towers are limited or obstructed, users experience issues such as poor call quality, shorter device battery life and slow data transfer.

These issues can wreak havoc on business operations, disrupting communications and stifling productivity. Distributed antenna systems give businesses the coverage they need to continue operations without cellular disruptions.

When a high volume of cellular users exists in one place, such as at a sporting event, the existing cellular network may not have the bandwidth to support all users. This leads to stifled communications and unhappy patrons. Large DAS networks can be installed to expand capacity in order to adequately serve all users and prevent disruptions in cellular services.

DAS are used by cellular companies in areas where traditional cell tower installation is not possible. Since distributed antenna systems are much smaller, they are a better choice for use in congested areas with high volume. Strategic antenna placement helps these companies avoid user disruptions due to distance from cellular signals.

Who Uses DAS?

Distributed antenna systems are used both indoors and outdoors and are found useful to enhance cellular networks in areas such as:

  • Businesses
  • Hospitals
  • Hotels
  • Airports
  • Subway stations
  • Tunnels
  • Entertainment facilities
  • Arenas and stadiums
