I recently had a discussion with our DAS (Distributed Antenna Systems) business manager. The following post is excerpts of our conversation. Our conversation revolves around the requirement for Emergency Responder Radio Coverage in buildings (International Fire Code ICC Section 510) and National Fire Protection Association (NFPA 72). DAS systems along with signal boosters are used to provide first responder/public safety radio coverage in buildings and other structures.
Part 2 of 3
One example, we just had a project in LA where the customer started the project in 2012. He hadn’t thought about the DAS since even though it was in the scope in the beginning. They took it out of the scope and didn’t think about it, three years later literally the day before occupancy the fire marshal comes in and says you need a DAS system. The owner ended up having to pay extravagant fees because they could not occupy the building until the DAS system was put up and it took about 6 weeks to get the system in because it takes a long time to get specific amplifiers in low frequency bands such as VHF and UHF. In that case it probably cost the guy a couple extra hundred thousand dollars just because he waited when he could have planned up front. We run into this sort of situation, it seems like almost every day.
