Distributed Antenna Systems (DAS): The In-Building Wireless Infrastructure Increasingly Required in Commercial Buildings

Distributed Antenna Systems (DAS) provide cellular and public safety wireless coverage inside large buildings where outdoor signals don't penetrate. Public safety DAS (per IFC and NFPA 1221) increasingly required by code. Cellular DAS supports occupant connectivity. Understanding DAS construction helps GCs coordinate this specialty low-voltage scope.
