DAS Systems and critical communication
How to improve critical communication inside and outside a building?
In case of an emergency, having coverage inside and outside your building to communicate with other people and public safety teams is a matter of utmost urgency.
The problem with some buildings is that they are constructed with materials or are present in areas that block radio, cellular, and internet communication signals.
These conditions make critical communication difficult when needed most.
What’s critical communication?
Critical communication or mission-critical communication networks are used in case of emergencies so that first responders can communicate with each other successfully and proficiently.
Mission-critical communication networks consist of equipment, infrastructure, devices, and systems. They ensure that public safety teams such as EMTs, dispatchers, firefighters, and law enforcement, can stay connected, coordinated, and informed in real-time during rescue missions.
The role of ERRCS in improving critical communication
Let’s start by defining ERRCS. Emergency Responder Radio Communication Systems or ERRCS are in-building communication systems employed to amplify critical communication inside and outside a building.
Having an ERRCS in every residential structure is mandated by the NFPA and Authority Having Jurisdictions (AHJ).
ERRCS, also known as Public Safety DAS, uses smaller antennas (Distributed Antenna System or DAS) that allow first responders to maintain a steady transmission of communication with one another using two-way radio signals.
DAS Systems engineers install ERRCS in your building by joining a Bi-Directional Amplifier (BDA) system to the donor antenna.
The antenna receives signals that operate on private frequencies via first responder networks.
The BDA uses cable or fiber and receives external radio signals to connect to a DAS and amplify the signals of buildings located in areas with poor coverage.
A public safety DAS limits property damage and casualties by using high-speed data transfer of 1 gigabit per second, surpassing the average phone line transmission speed of 384 kilobits per second.
Whether it’s a natural disaster (tornadoes, hurricanes), a fire, or a medical emergency, public safety DAS gives first responders unequaled usage of their radios and allows them to plan and execute evacuation routes in buildings. But what about civilians?
The importance of Cellular Das in emergencies
What if a fire starts and you find yourself locked in the building’s 12th floor? Or find a loved one passed out in the building’s basement? You will need Wi-Fi 2-way communication to contact dispatchers for help.
Cellular DAS differs from Wi-Fi, it heightens cellular signals, facilitates internet communications, and gives you better cell phone reception whether you’re indoors or outdoors.
With Cellular DAS, the days when you could not communicate with your nest Wi-Fi point are over as it functions with Wi-Fi, voice calls, and data services like 5G, 4G/LTW, and 3G/HSPA+.
Installing DAS provides civilians with more coverage while handing them a lifeline that improves communication and allows them to stay connected with emergency services personnel during dire situations.
From the get-go, Cellular DAS Systems are designed with the purpose to improve communication by providing good signal strength. Because every building comes with specific challenges, our professional technicians will design bespoke DAS systems that rise to all of them.
Even though Cellular DAS systems don’t initially target public safety, they provide quality coverage with minimal latency, low packet loss, good voice quality, low jitter, and high throughput. In other words, they can literally save your life.
Whether you’re a first responder or a civilian, when danger strikes you will need an efficient way of communication to ensure your survival.
Our ERRCS and Cellular DAS systems are tailored to offer both parties a stable and persistent means of communication.
Your safety is our priority! The team of engineers at DAS Systems is available to design bespoke ERRCS and Cellular DAS Systems, test them, and install to improve critical communication during emergencies. Reach out for a consultation!
