INTRODUCTION
BLUETOOTH is a Wireless LAN Technology
Bluetooth is a wireless technology that allows enabled devices to sync and transfer information
It is designed for short range RF communication replacing the need for physical cables and infrared beams while maintaining security
It operates in the 2.4 GHz band
Key Features: Robustness, Low power consumption, Low Cost
BLUETOOTH Historical perspective
In 1876, Ericsson initiated Bluetooth technology movement to eliminate wire clutter in homes and offices.
February 1998 - SIG
(Ericsson Mobile, Intel, IBM,
Toshiba and Nokia Mobile)
Technology Overview
Bluetooth technology is the implementation of the protocol defined by IEEE . / 802.15
Wireless Personal Area Network (PAN) operable in an area of size of a room or . Hall
The Bluetooth protocol operates in the license-free ISM band at 2.4-2.4835 GHz. To avoid interfering with other protocols that use the 2.45 GHz band, it divides the band into 79 channels (each 1 MHz wide)
It changes channels up to 1600 times per second as it uses Frequency Hopping spread spectrum (FHSS).
Supports data speeds of as much as 721 Kbps & three voice channels
