(Teddi: With this blog post, Vertiv provides valuable information about power protection for Distributed Antenna Systems, particularly in environments like Healthcare facilities and venues.)
Distributed Antenna Systems (DAS) distribute and amplify radio frequency signals throughout buildings and across similar small footprints, providing better coverage and higher bandwidth to guarantee reliable service even during peak usage events. DAS systems often are used at large events – like the Super Bowl – to ensure wireless providers can handle the large amount of data generated by attendees. Hospitals use DAS to make sure critical mobile calls and communications aren’t dropped and to ensure first responders can communicate reliably in emergencies.
Unlike the typical cellular DAS systems, newly-deployed public safety DAS systems must satisfy three main requirements to make sure the systems are always available and dependable.
The DAS must have a fully waterproof installation using NEMA enclosures. This ensures the equipment can withstand harsh environments or inclement weather. With a waterproof installation, a flood or downpour won’t disrupt communications in the building.
When public safety systems need to communicate, a power outage shouldn’t stand in the way. For this reason, DAS deployments require a battery, small UPS system or generator to provide backup power in the event of a utility outage. UPS systems provide transitional battery backup during power disturbances, so the DAS can continue to function normally while shifting the load to the generator.
Monitoring and Alarms
DAS isn’t a “set it and forget it” system. Maintenance, monitoring and alarm notifications make sure the system is available and running at peak efficiency 24 hours a day, seven days a week.
Public safety systems typically require more extensive in-building coverage than commercial networks. This means coverage in places that can create communication challenges, like stairwells, elevators, and parking structures.
