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
We want 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
Distributed Antenna System 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. The installation of these systems must be completed 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.

Let's TalkERRCS
An emergency responder radio communications system (ERRCS), also known as a public safety or first responder DAS (Distributed Antenna System), has become a mandate in-building requirement for many municipalities around the State and Country. This network essentially re-transmits fire or police radio frequencies from outside a building, where the signal is presumably stronger, into the building, where it usually is weaker or non-existent. These signals are imperative for the first responders to be able to communicate with their peers outside of the building during an emergency.
We do annual certification testing for 800Mhz DAS
Cellular Distributed Antenna System
It has been estimated that 80% of cellular phone calls begin or end inside a building. According to NENA, an estimated 240 million calls are made to 9-1-1 in the U.S. each year. In many areas, 80% (roughly 192M) or more are from wireless devices. 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. It will make the equipment you already pay for perform even better! We conduct annual DAS certification with T Grid testing and coordinate the results with the local governing authorities. If you have any questions, please contact us or give us a call.

What is PSERN and why do I have to provide a compatible system?
PSERN is the Puget Sound Emergency Radio Network, a voter-approved effort to replace our region’s aging emergency radio system with a modern, reliable network that provides greater coverage throughout King County.
When completed, the new system will be used by first responders — including police, fire and emergency medical personnel — in all 39 King County cities and throughout unincorporated King County.
* PSERN has extended certifications into 2024. Please contact us to get your DAS tuned to the proper frequencies for certification and get on our annual maintenance contract for recertifications.
PSERN is jointly owned by the City of Seattle, King County, Eastside Public Safety Communications Agency, and Valley Communications. An interlocal agreement outlines PSERN’s governance and operations. Every day throughout our region, first responders use outdated radio equipment. PSERN is building a modern system that provides the coverage and reliability needed to keep our communities safe.
The current system in use in the Puget Sound area is more than 20 years old and was designed in the mid-1990s to serve a smaller population across a smaller area. The existing system has gaps in coverage, does not account for our region’s recent growth, and forces first responders to use different channels to communicate during emergencies. With this in Mind the local agencies are mandating that all buildings that fall under the specified parameters must be compatible by December of 2020.
What steps do I need to take to meet the required compatibility?
If you would like to know if your system is or can be made compatible, please contact us to arrange a site visit so our engineers can provide a review and, if needed, a plan to become compatible and provide the certifications to the proper agencies.
