Using Bluetooth, mobile phones, computers, and personal digital assistants (PDAs) can be conected in short-range without wire. Bluetooth is a global wireless communication standard that connects devices on a fixed distance. We can say this technically and explain that Bluetooth is a wireless technology standard that connects devices in short distance using short-wavelength UHF radio waves (in the ISM band from 2.4 to 2.485 GHz). Bluetooth was invented by telecom vendor Ericsson in 1994. It was initially made for alternative RS-232 data cables

History – This technology is named after the name unknown of the name of the harbor (in the mid-tenth century).
Maximum Range – The maximum range is 10 meters (33ft) [Class 2, most commonly found in mobile devices]

How Bluetooth works?

To connect Bluetooth devices, wireless waves use wires and cables. Any Bluetooth product, such as a small computer chip (transceiver chip-transmits and receives frequency) with a headset or watch Bluetooth radio, and software to connect it. When two Bluetooth devices have to be connected together they have to pair. Communication between Bluetooth devices is very short-range, which is called ad hoc networks known as Piconet. A Piconet is a network of devices. The network ranges from two to eight connected devices As soon as the Bluetooth devices enter the radio proximity or outflank, Piconets gets installed dynamically and automatically. When the network is established between devices, a device master and another device performs the role of the slave.

Bluetooth Technology Advantages: –

Best for short range communication
Not dependent on wires and cables
World wide acceptable standard

Bluetooth Technology Disadvantages: –

Made only for short range
Data transmission
Not suitable for high bandwidth
