Distributed Antenna System (DAS)
Commonly referred to as DAS, a Distributed Antenna System provides and/or expands network connectivity in areas where:
- Space may be limited, such as areas where traditional cell towers cannot be installed.
- There is high volume usage and networks can get congested or overwhelmed such as stadiums and other large event venues.
- Dead zones occur and coverage would be limited and/or non-existent otherwise.
A Distributed Antenna System uses a network of spatially separated antenna nodes, connected to a common source to provide wireless service coverage in a building, structure or limited geographic area. It can be deployed both indoors (iDAS) and outdoors (oDAS).
Emergency Radio Responder Communications Systems (ERRCS)
Many jurisdictions now require Emergency Radio Responder Communications Systems (ERRCS) coverage that are NFP or IFC-compliant as a prerequisite for getting a building occupancy permit. This network infrastructure works by re-transmitting essential emergency responder radio signals into a building or campus to strengthen the connection or signal. Plus, it allows emergency responders to maintain constant communication, even in hard to reach areas, such as stairwells and basements. It performs an important function which can help decrease critical response times and may even save lives.
Public Safety DAS
A public safety Distributed Antenna System (DAS) is one of the most popular and efficient ERRC systems available. This type of system uses a directional antenna, typically mounted on the roof of a building to receive the ERRCS donor signal. Then it disperses the signal via indoor omni-directional antennas to ensure constant access to ERRCS communication signals. It’s one of the best options available that’s reliable and routinely passes local Authority Having Jurisdiction (AHJ) coverage testing protocols.
