What are the requirements for a Bluetooth mesh device layout?

Theoretically, Bluetooth mesh devices can cover an indefinitely large space because they can function as trunks to transmit data to each other. The effective communication distance indoors between each two Bluetooth mesh devices is about 10 m. To ensure an effective Bluetooth mesh communication network, a Bluetooth mesh device that is powered by a socket must be available within the 10 m radius circle of another Bluetooth mesh device. Battery-powered devices, for example, low-power sensors, do not have data relay functions.
