"BLUETOOTH represents a single chip, low cost, low power radio based network technology for Wireless Personal Area Networks (WPAN)"
Bluetooth wireless technology is a short-range communications system intended to replace the cables connecting portable and/or fixed electronic devices. It provides Wireless interconnections between low power, short range, small mobile devices (Palmtops, Laptops, PDAs, phones, etc) in close proximity (within a room, car, cabin, elevator…) Bluetooth technology
- Provides freedom from wires
- Supports creation of Adhoc piconets and Personal Area Networks(PAN) with limited coverage (within the range of 10 ms)
- Doesnot require Infrastructure support like Switches, Access Points, hubs, routers, etc. for establishing interconnectivity
- Connects Keyboard, mouse, printers, headphones, head sets with speakers etc. to PC without wires.
- To Interconnects hand held, portable, battery operated devices like mobile phones, hands free equipment with mobile phones, PDAs, mobile computers, communicators,, microphones, wireless speakers to home theatre systems
The Bluetooth core system consists of an RF transceiver and follows IEEE 802.15 standards. The system offers services that enable the connection of mobile devices and exchange of a variety of data (voice, music, graphics, text) between these devices.
Bluetooth consortium was formed by 5 companies in 1998 i.e. Ericsson, Intel, IBM, Nokia and Toshiba. Blue-tooth standard is adopted by over 1000 manufacturers of electronics appliances (Akai, Motorola, LG, Samsung, Nokia, for music, video, data, fax m/c ……)
