When the devices are in range of one another, the Bluetooth signal will be picked up and the user can then communicate with the other device. There are different categories of Bluetooth capabilities, which determines the range the Bluetooth can work at: [|mW] ([|dBm]) ||~ Range (approximate) || ~From Wikipedia: []~ A Class 1 Bluetooth would be a transceiver for other bluetooth devices. Sort of like a "hub" for other Bluetooth device to meet. Many Universities nowadays will have such transceivers for students to communicate with one another. A class 2 Bluetooth is found primarily in mobile phones, laptop computers, and other devices capable of sending and receiving shorter Bluetooth signals. A Class 3 Bluetooth, are not nearly as common as the class 2. They can be found in cars, hands-free handsets, and other very shortwave Bluetooth devices.
