Bluetooth is a short-range wireless technology that allows electronic devices to connect and communicate without wires. It operates by establishing small personal area networks (piconets) between devices like computers, phones, and headphones. A piconet can have one master device communicating with up to seven slave devices using frequency hopping to switch rapidly between channels for increased security and reliability.

1. BLUETOOTH
Bluetooth is a universal
radio interface in 2.4 GHz
frequency band that enables
electronic devices to connect
& communicate wirelessly
via short range.

2. BLUETOOTH HISTORY
• Invented in 1994 by L.M.Ericsson,Sweden.
• Named after Harald Blaatand “Bluetooth” , King
of Denmark 940-981 AD.
• Currently Bluetooth trademark is owned by the
Bluetooth SIG, a consortium of companies
having stake in bluetooth.
• More than 2000 members today.

3. BLUETOOTH OPERATION
• Piconet (PAN) is the fundamental form of communication for
Bluetooth Wireless technology.
• Master & Slaves.
• The master Bluetooth device can communicate with up to 7
devices.
• Data can be transferred b/w the master & one other device.
• The master switches rapidly from device to another in a round-
robin fashion

4. A BLUETOOTH COMMUNICATION SCENARIO
All devices in a piconet use the same frequency-hopping pattern

5. HOW BLUETOOTH CREATES A
CONNECTION????
Bluetooth takes small-area
networking to the next level
by removing the need for
user intervention and
keeping transmission power
extremely low to
save battery power.

6. COMPUTER REQUIREMENTS & O.S SUPPORT:
• Apple has supported Bluetooth
since Mac OS X v10.2 which
was released in 2002.
• For Microsoft Windows XP
