Based on the article they are using the 920Mhz range which would imply a 10m range if current standard continue.
So active sensors for a warehouse (or house) to cover 10m bubbles would be pretty useful. Especially when you add something like an Bluetooth/WiFi/Z-Wave/Matter/etc bridge/mesh.
There is a very scare element to this though, as these chips could easily be used nefariously too though.
