My jaws dropped when I looked up the failure rate on wireless door sensors in a concrete building lobby
Did a deep dive into the data from a 2023 installation in a high-rise in Chicago and found out that over 30% of wireless sensors in those metal-heavy lobbies fail within the first 6 months - has anyone else hit this kind of surprise with signal interference?

Right? That 30% number is brutal, but honestly it makes total sense when you think about all the rebar and metal studs in those lobby walls. We had a similar issue in a building downtown, the concrete was basically a Faraday cage (blocked damn near everything) and killed the signal from the sensors that were closest to the structural columns.

Oh man, that brings back a memory. We had this old building downtown we were wiring up for a smart building project and the elevator shaft was basically a black hole for any wireless signal. We ended up having to run literal cables down the shaft just to get data from the sensors we put in the mechanical rooms. It was wild because the plans showed all this fancy open space but the actual concrete was like a thick wall of lead. I swear the architect must have been a fan of old school fallout shelters or something.
