Range

The Bluetooth range of a single device varies from device to device and can be up to 50 meters outdoors. 2.4 GHz radio signals can be disrupted by water, concrete or other electronic devices. Due to these disturbances, the average range per device within buildings is reduced to about 5 meters. However, the range can be extended by connecting additional Connect Mesh devices (Mesh principle). This also further enhances the reliability of messages sent over the network. The distance between two devices should not exceed 5 meters.

Optimizations:

• Central positioning, so that signals can be transmitted or received in all directions.
• Avoid sources of interference such as metal, walls, water pipes, etc.
• Reduce electronic devices within the radio range

Absorption

Radio signals are absorbed and weakened when penetrating objects, the extent of which depends on the thickness, type, and density of the material. Higher moisture of the objects also has a dampening effect.

Reflection

Some materials have a reflective effect, i.e., radio signals are transmitted with significant losses or not at all, and reflected, particularly metallic surfaces have this property, for example, construction steel, metallic door frames, metal cabinets, metal foils of thermal insulation and metal-coated heat protection glass.
