In the event of a crisis, public safety personnel and first responders require reliable emergency responder radio coverage. Being able to communicate with public safety two-way radio systems in buildings is crucial for first responders to execute time-sensitive and mission-critical tasks to protect the public. Emergency Responder Radio Communications Systems (ERRCS) are often installed to provide these necessary means of communication. Avari Wireless's public safety digital Distributed Antenna System (DAS), known as the Avari® VitalLink™ Series, provides a reliable, high-performance, and high availability system designed to support both current and future public safety communication requirements. Avari's systems are enabling emergency communications indoors, which helps keep public safety personnel, first responders and the public alike safe.
