For large facilities (3100-1000 Series), medium facilities (3100-1500 Series) and for small facilities (3100-5100 Series). CELLULAR DAS—PASSIVE SYSTEM • Typically used in smaller, less complex stand-alone buildings. 1. A distributed antenna system, or DAS, is a network of spatially separated antenna nodes connected to a common source via a transport medium that provides wireless service within a geographic area or structure.DAS antenna elevations are generally at or below the clutter level, and node installations are compact. The offeror shall design, install, and maintain a Distributed Antenna System (DAS) that provides voice and data cellular communications coverage for [agency]; a [X] square foot building. Codes and Requirements . Permanent external filters or attachments shall not be permitted. A BDA (Bi-Directional Amplifier) system is an in-building communication system that brings wireless signals into a structure from outside, amplifies those signals with a signal booster, and then evenly distributes the amplified signals throughout a structure via a Distributed Antenna System (DAS). Assembly/installation of all components shall comply with the National Electrical Code. In 2016, the code said that the signal has to be strong enough to provide a minimum audio quality of 3.0, which is defined as speech understandable with a slight effort, and which requires occasional repetition because of noise and distortion. Components utilized in the installation of the public safety radio enhancement system, such as repeaters, transmitters, receivers, signal boosters, cabling, and fiber-distributed antenna systems, shall be approved and shall be compatible with the public safety radio system. 5.2.4* System Radio Frequencies. Cables that connect public safety equipment should have a 2-hour fire rating – the same applies to the room containing all equipment.
