What should we keep in mind when installing Bluetooth beacons or sensors in a factory, 倉庫, or office building?
The most important rule is avoid direct contact with metal surfaces. Metal absorbs and reflects Bluetooth (2.4GHz) 信号, which can reduce signal strength by 50% or more—leading to poor coverage, lower positioning accuracy, or even failure to connect with gateways.
For best performance, mount devices on non-metallic surfaces such as concrete walls, drywall, wood, or plastic.
