Fault-Tolerant Public Safety System

 
First responders require seamless service at all times and cannot afford to experience disruptions in communications for any reasons. Staying connected at ALL times is a baseline requirement for an Emergency Responder Radio Coverage System (ERRCS).

Although redundancy is not a mandatory requirement, it is one factor to be considered to minimize single point failures in a public safety wireless communications system to provide the desired reliability. The most basic form of network redundancy is duplicating the system in its entirety, 1:1 redundancy. Full system redundancy is ideal and very effective, but in many situations, it may not be an option due to space and cost.

In this article, an alternative and cost effective method will be described – a fault tolerant system.
