What is it?
Bluetooth is a way of transmitting information between different devices using radio technology. It works when the devices, such as your mobile phone and your hands-free headset, are within short range, but they don't have to be in line-of-sight with each other.
How does it work?
According to the How Stuff Works website,when Bluetooth-capable devices come within range of one another, an electronic conversation takes place to determine whether they have data to share or whether one needs to control the other. Both devices must have Bluetooth turned on, but once it is, the electronic conversation happens automatically. You may then be asked to give permission for the two devices to communicate.
Why is Bluetooth useful?
Bluetooth connections are wireless and you can have several devices working together at once. For example, your computer may use Bluetooth to connect to your wireless mouse, keyboard and printer. Bluetooth uses little power.
What do you need to keep in mind if your children are using Bluetooth devices?
How Stuff Works says that in any wireless networking setup security is a concern. Devices can easily grab radio waves out of the air and with Bluetooth, the automatic nature of the connection means people could send you data without your permission. If your child has a Bluetooth-enabled mobile phone, there will probably be a preference setting for you to select 'trusted devices' - such as your hands-free headset - that can exchange data without asking permission. When any other device tries to establish a connection to the phone, the phone will ask permission before allowing the connection. Alternatively, you may want to turn off the Bluetooth function altogether, so the phone becomes 'invisible' to other users.
