Bluetooth Range Estimator tool calculates range between two devices
It takes account of several representative environments by letting you input the key variables for calculating the effective range.
The tool lets you select, for example, a Bluetooth physical layer to see how it influences typical receiver sensitivity, and adjust for transmit power, transmit antenna fain and receiver antenna gain. The representative environments you can choose from are: Outdoor, Industrial, Office and Home.
The end result is a distance quoted in metres.

The most well-known Bluetooth use cases, including personal audio and wearables, have design requirements that dictate a shorter effective range. Developers of these traditional solutions have therefore chosen to implement the technology and their hardware in a manner that delivers a maximum range between 10-30 meters.
However, developers are also using Bluetooth to achieve a reliable connection range of more than a kilometre to support exciting new use cases. Some of these include industrial asset tracking, large-scale sensor networks, and even reliable remote control of Beyond-Visual-Range (BVR) drones. The Bluetooth Range Estimator will help improve understanding of Bluetooth range capabilities going forward.
