What is Bluetooth

To connect one electronic device to another, one normally uses cables, wires, plugs and a vast number of other components which make the device quite complicated. For example a TV will normally connect to a VCR and a cable box. with a remote control for all three components. Or a CPU unit will have to be connected to a mouse, a keyboard, a printer and so on with many cables and plugs. Sometimes, it becomes so complicated that one wonders whether considering a degree in electrical engineering would not be too far out.

But recently, a new kind of wireless technology has been making waves in the info- tech industry . This is what is known as Bluetooth technology, it is wireless and automatic and has been changing lifestyles the world over.

What is BluetoothBluetooth is a standard developed by a group of electronics manufacturers that allow` any kind of electronic equipment to make its own connections, without wires, cables or any physical contact. Bluetooth works on global radio-frequency (RF) standards, which operates on the 2.4 GHz ISM band. So when you travel, you don`t have to worry about keeping track of a briefcase full of cables and components . Its also inexpensive and you don`t need to be an electrical engineer to figure out where the wires will go.

Actually, you don`t need to do anything really. The devices find one another and strike up a conversation without any user input at all.

Infra red also is a wireless technology and relatively cheap; but Bluetooth scores over this because it does not need a "line of sight".

In a roomful of devices which are all running on Bluetooth, will there be a mix up? The answer is no, because the manufacturer of each product ( cordless, pc, dvd, tv etc) has programmed each unit with an address for a particular type of device. When The base of say a cordless phone, is turned on, it sends radio signals asking for a response from other units with an address in a particular range. Since the handset of the cordless phone has a corresponding address , it will respond. Even if these devices receive a sienal from another device it will ignore them since it is not from within a known network. Once the network is established the devices begin "talking" amongst themselves.

Secondly, it helps the teacher to see whether the student has understood the lesson and thirdly, it helps the students to learn how to find and use more information on a subject. But most importantly it is the link between the school and home to show what progress is happening.
