Bluetooth is a wireless technology standard launched in 1998 that allows for instant wireless connectivity between mobile devices like phones, laptops, and other electronics within 10 meters of each other. It uses short-range radio signals to exchange data and voice transmissions without needing a direct line of sight. Bluetooth eliminates the need for wired connections and allows devices to automatically synchronize and connect when in range. Potential applications include unlocking doors, automatically checking into hotels, and wirelessly printing between rooms.

ABSTRACT
Wireless communication revolutionalized the entire world.
t t dd
Bluetooth is one of the newest technologies whose main strength is its ability to
simultaneously handle both data and voice transmissions.
ssuu
Bluetooth is a new technology and standard, launched in 1998. It is
essentially, a small microchip, which uses a short-range radio link to exchange
information, enabling wireless connectivity between mobile phones, mobile PCs and
other peripherals. When two Bluetooth enabled products come within 10 meters of each
w. .
other, they will automatically connect and synchronize. Because the technology uses a
w
short-range radio link, it means that line of sight is not required for it to function.
Bluetooth wireless technology eliminates the need for numerous
wired connections to other devices. Connections are instant and are maintained even if
ww
the devices do not have a clear line of sight. The range of each Bluetooth enabled device
ww
is around 10 meters but optionally reaches distances of up to 100 meters with an
amplifier.

The possibilities for Bluetooth are huge. When arriving home, your
PDA (Personal Digital Assistant) synchronizes with your house and the front door
unlocks, preferential lighting comes on and any other pre-set configurations become
om
active. Approaching your car, the door unlocks, the radio tunes itself to your preferred
station and preset preferences become active.. As you arrive at the reception of your
hotel, you are automatically checked in. Your room number and electronic key are
transferred to your PDA. As you approach your room, you will be able to unlock the door
via your PDA. Bluetooth is regulated by governments worldwide.
i.c
Bluetooth also uses a short packet length, which is another benefit.
This technology is suited for low-power, low-cost radio implementations and is used in
some wireless LAN products.
og
Software has developed something called ProximityMail which uses
Bluetooth to create a spontaneous "Relay Area Network" (RAN) in which users can
exchange text messages via PDA’s without the e-mail addresses of mobile phone
numbers within ad-hoc networks. Using this new technology, it will soon be possible to
nty
send a print command from your computer to the printer in the next room, via radio link
directly through the wall!
