Resilient communication networks keep public safety agencies in touch despite power disruptions and extreme rain.
Storms and extreme weather conditions are a challenge for public safety. Think back on the following:
Since 2010, Europe alone has seen several rough years for the weather. Storms have raged across the continent, causing disruptions in country after country.
What are shock-proof networks? Download the Shock-proof networks white paper. It describes the challenges related to exceptional situations and actual solutions that have helped emergency services cope with extreme situations.
So how do the authority networks cope in the aftermath of severe storms, with power disruptions and extreme rain threatening to interrupt transmissions?
Resilient network design can mitigate transmission problems. The right design ensures that there's always an alternative route from each base station to the network switch.
Connecting the base stations in one or more loops of microwave links or leased lines, for instance, means that every base station has at least two transmission routes. If one link fails, the transmission is automatically rerouted.
But a violent storm can bring down more than one connection at a time, cutting off base stations from the network switch. In this case, resilient radio networks' base stations will continue to operate in fallback mode.
Fallback mode keeps users communicating - even when a storm cuts off their base station, and they're out of range from the rest of the network. Here's how it works on Airbus TETRA networks:
These measures - combined with extremely robust equipment - keep shock-proof networks in action when other networks may fail. That means that people who will manage the disruptions when the storm has passed can get on with their jobs whatever the weather.
