Beaver Dam Community Hospital In-Building Safety Communication System
Fire Fighters, Police Officers or Emergency Medical Technicians, our front line workers, should not have to be
concerned with whether or not their “lifeline”, the two-way radio on their belt, will work when they are faced witha stressful, potentially life-threatening situation. Most public safety radio systems are not necessarily built for in-
building coverage and why an In-Building Public Safety Communication System is so critical. Please read the following case study on how NCI solved the in-building coverage issue at Beaver Dam Hospital.
PROBLEM: At a local community hospital, in Beaver Dam Wisconsin, the local fire and police departments had some
very legitimate concerns with the little to no radio communications service once public safety personnel entered the
facility, which happens almost daily.
SOLUTION: Nielson Communications was approached in the fall of 2018 by the hospital facilities manager, Marc
Teubert and City Fire Chief, John Kreuziger, to address the inadequate public safety radio coverage inside the
hospital. NCI was tasked to design an in-building communication system to solve the coverage issues.
NCI’s first step was to meet with the customer to determine their areas of coverage concern which was quite
prevalent throughout most of the hospital. “We had little to no radio coverage when personnel enter the hospital,
especially in the ER area.” said Deputy Chief Mathew Christian of the Beaver Dam Fire Department. This was a major
concern for the public’s safety as well as for the officers, EMT’s and fire fighters.
In order for the bi-directional amplifier manufacturer, Westell, to properly engineer an in-building bi-directional
amplifier (BDA) and a distributed antenna system (DAS) a design request survey was needed to be completed. This
requires a site survey by a certified RF technician to measure donor signal strength, signal from the nearest tower
site, and the indoor signal levels throughout the hospital to determine base levels.
All signal levels along with digital audio quality (DAQ) are recorded which is then sent to engineering along with the design request survey. Once Nielson Communications receives the design and bill of materials (BOM) a proposal was developed and presented to the facilities director and Chief Deputy for review, submittal for budgetary approval and the final approval.
Once NCI received the “thumbs up” from the facility director the equipment was ordered and installed within sixty
days. Upon completion NCI did a walk-through with the hospital facility director and the Police Chief to test signal
strength and digital audio quality which results were excellent.
The in-building public safety communication system consisted of a single VHF bi-directional amplifier (BDA) and
eleven in-door antennas which made up the distributed antenna system (DAS) located on each of the three floors of
Police, Fire and EMT’s can rest assured they will now have the communications they need within Beaver Dam
