Distributed Antenna System in California
Distributed Antenna System guidance for California building owners, technicians, and integrators. State-specific ERRCS requirements, AHJ expectations, and next steps.
Distributed Antenna System support in California
A DAS (Distributed Antenna System) is the network of antennas and cabling that distributes radio signals throughout a building. In ERRCS applications, the DAS connects to bi-directional amplifiers (BDAs) and extends enhanced public safety signals to all areas of the building. The DAS typically includes donor antennas that capture outdoor signals, coaxial or fiber cabling, and indoor coverage antennas strategically placed throughout the structure.
BDA Systems supports owners, contractors, and technical teams throughout California. We align project scope with local AHJ expectations, adopted code language, and the practical realities of getting from failed testing to final approval.
Key Compliance Questions
- What is the difference between DAS and BDA?
- Can a commercial DAS serve as ERRCS?
- How many antennas does a DAS need?
