Leaving the Bluetooth transmission range
Wireless calling and streaming are only possible in the Bluetooth

largely depends on environmental conditions such as wall thickness,
wall composition etc. With a free line of sight, the transmission
range of most smartphones and Bluetooth devices is up to 10 meters.
