The wireless link adapter will need to be connected to your existing system/receiver with cables which are included. Guesstimating, these cables are maybe 3 or 4 feet long allowing you a little bit of movement for finding a good signal for your adapter. You will set it up to be used wirelessly from your wi-fi via the SoundTouch app. My router is maybe 30/35 feet away upstairs. Once set up, you can then use the app for Bluetooth connectivity with other devices.
