What Is a Distributed Antenna System?

A DAS (Distributed Antenna System) is a network of antennas, cabling, and signal sources that rebroadcast cellular signal throughout a building.


It’s the gold standard for improving coverage in large or signal-impaired environments, especially where compliance or public safety is involved.
