Communication reliability in modern wireless fire alarms. Radio propagation in a burning building and measures to counteract signal fading

Most misconceptions about wireless fire alarms come from negative experiences with legacy systems that do not support the mesh network technology and are unable to provide multiple reserve connections to the devices. Modern solutions do not suffer from radio communication issues, implement various measures to ensure connection stability, and provide each device with several ways to deliver the signal. In normal conditions, wireless alarms are just as reliable as wired systems, and when it comes to operating in a burning building, radio communication provides an additional benefit as it can continue working even when a big part of the network is damaged by the fire.
