The Future of Communication
Distributed antenna systems
Modern construction techniques and materials block or degrade internal and external wireless communications. Distributed antenna systems (DAS) were designed to extend wireless coverage within structures and enable radios and cell phones to work regardless of their position within the building.
Fire Codes and Ordinances
To meet the critical need of fire, police, and medical teams to communicate using “Emergency Responder Radios” inside large structures, communities are adopting the codebooks set forth by the International Code Council (International Fire Code) and the National Fire Protection Association (NFPA). In-building radio coverage requirements are met by taking the outside radio signal to a Bi-Directional Amplifier (BDA) device, and distributing it throughout the facility using a Distributed Antenna System (DAS).
DAS Design & Implementation
DAS design and implementation can be quite complex. There can be many variables in DAS requirements based on the municipality. Frequencies, battery backup requirements, coverage requirements, and more can all be different, even in neighboring cities.
DAS systems need to be designed and tested using specialized software and hardware. These systems must be installed and tested by FCC licensed technicians. They must be re-tested every year to maintain proper operation. Industrial Communications and our partners offer local expertise when navigating these regulations and implementing solutions.
We do annual certification testing for 800Mhz DAS
Cellular DAS
It has been estimated that 80% of cellular phone calls begin or end inside a building. A cellular DAS allows building owners to add value for their tenants and their employees by enabling the use of mobile devices throughout the building. A DAS can support multiple carriers and even improve the battery life of phones.
We conduct annual DAS certification with T Grid testing and coordinate the results with the local governing authorities.
