Bluetooth Connection Locations
Bluetooth is a wireless technology that uses radio waves in both fixed and mobile devices to send data over short distances.
- Open the SETTINGS app on your phone, then select BLUETOOTH.
- Verify that Bluetooth is enabled (the green button should indicate this).
- Verify that your Bluetooth device is turned on and in the discovery mode. Watch for it to appear below the Bluetooth settings on your device under MY DEVICES.
- To start the connection, tap the name of the device you wish to pair with. If the device you’re connecting to needs one, you might be prompted to enter a special code.
- Open the SETTINGS app on your phone, then select BLUETOOTH (or SETTINGS > CONNECTIONS > BLUETOOTH).
- Verify that your Bluetooth device is turned on and in the discovery mode. Watch for it to appear on your phone under AVAILABLE DEVICES.
Bluetooth Pairing with Phones
Bluetooth—named after a Danish king from the tenth century—transmits data directly between two devices via radio waves. Compared to Wi-Fi and cellular signals, which are two other popular methods of connecting devices, Bluetooth uses radio waves that are far weaker. Because less energy is required to produce weaker radio waves, Bluetooth is especially beneficial for battery-operated devices. Additionally, Bluetooth usually only functions over short distances—less than 30 feet, or roughly 9 meters—due to those weaker radio waves. Without the assistance of a router or any other device, a Bluetooth connection between two devices will continue to function as long as they are within range of one another. Around 2.4 GHz, 79 distinct radio frequencies are used by Bluetooth in a narrow band. When two devices are paired, they choose at random from among the 79 frequencies that are available to form a connection. After that connection is made, the devices repeatedly hop across these frequencies several times per second.
