Enabling Reliable First-Responder Communications

Given heightened awareness around national and local security, new federal regulations mandate the provision of reliable wireless communications to ensure public safety. In the event of an emergency, it's critical for first-responders to be able to have access to radio communications anywhere and everywhere, including inside buildings.

​How Does DAS for Public Safety Differ?

Extending in-building wireless (DAS) communications for public safety works substantially the same as a standard DAS for cellular service. The main difference is in how the donor signal is received from the public safety cell site.

Rather than a base station transceiver (BTS)  installed in the head-end equipment room, an antenna is installed at the building rooftop to receive the donor signal from the public safety cell site.

The RF signal is sent to a bi-directional amplifier, and on to the head-end equipment which converts the RF signals to digital pulse signals. Digital signals are sent via fiber cabling to fiber remotes and antennas located through the building. Multiple cellular and public safety technologies can be supported on a single DAS.
