Systems and methods for detecting events based on wireless signal degredation

A system for detecting an event within a building, the system comprising:

• a wireless network comprising a plurality of wireless devices distributed throughout the building and configured to:
• record a baseline signal characteristic that characterizes a wireless radio signal transmitted between transceivers of the plurality of wireless devices during a baseline time period;
• record a second signal characteristic that characterizes the wireless radio signal during a second time period after the baseline time period;
• a controller configured to:
• detect an event comprising at least one of a fire within the building or an increased level of water vapor within the building in response to a determination that the second signal characteristic is abnormal relative to the baseline signal characteristic;
• and
• trigger an alarm in response to detecting the event.

A method for detecting an event in a space in or around a building, the method comprising:

• recording a baseline signal characteristic that characterizes a wireless radio signal transmitted between transceivers of devices in the space during a baseline time period;
• recording a second signal characteristic that characterizes the wireless radio signal during a second time period after the baseline time period;
• detecting an event comprising at least one of a fire within the space or an increased level of water vapor within the space in response to a determination that the second signal characteristic is abnormal relative to the baseline signal characteristic;
• and
• triggering an alarm in response to detecting the event.
