The radio signal can pass through walls, floors, and ceilings. The speaker, therefore, can be placed in different rooms in the home and still transmit sound. Signals can be transmitted over a range of up to 300 feet with some speakers, but the range varies depending on the brand.

Bluetooth speakers use a radio communication frequency so that the devices can be used without them being in the same visual line of sight. Portable wireless speakers have become very popular with consumers.
