The relevance of redundancy during severe weather

[...]

Municipalities can prevent system failures through redundancy – the intentional duplication of critical functions of a system to increase reliability – which keeps mission-critical communications functioning, so public safety professionals can continue to serve the community.

Uninterruptible Power Supplies (UPS) provide an immediate, short-term power bridge that keeps critical equipment operating without interruption when commercial power is lost. This allows radio systems, network equipment, microwave links, and site controllers to continue functioning while backup generators start and stabilize.

Although they can be vulnerable to damage during a storm, microwave dishes maintain communication with law enforcement, fire, emergency medical services (EMS), and other public safety agencies. They provide reliable, high-speed, point-to-point, and point-to-multipoint communication links that connect remote transmitter sites to dispatch centers.

To ensure a reliable, clear transmission, maintenance and testing must be done regularly: investigate receiver alarms and faults when they occur, update software, evaluate battery life, and measure the accuracy and strength of the signal.

This level of redundancy helps ensure reliable communications during both routine operations and major emergencies, allowing first responders to focus on their mission rather than the radio system supporting them.
