What is BlueTooth?
It is an open specification
for short-range communications
of data and voice between
both mobile and stationary
devices. For instance,
it specifies how mobile
phones, WIDs, computers
and PDAs interconnect
with each other, with
computers, and with office
or home phones.
Bluetooth is a wireless
protocol that is used
to communicate from one
device to another in a
small area usually less
than 30 feet.
Operates in the un-licensed
2.4 GHz range.-
uses fast frequency-hopping
technology to avoid interference
from other radio signals
when it transmits packets
of data.
It communicates with
a 1 megabit connection
between 2 devices
for both a voice channel
and a 721k data channel.
The Bluetooth specification
calls for different profiles
such as voice and serial
emulation to be used by
devices to communicate.
However interoperability
needs to be tested to
confirm compatibility
of the higher level protocols
that use Bluetooth to
communicate between devices.
Version 1.0 requires
users to register the
connection between the
2 devices while
version 1.1 allows
a Bluetooth device to
communicate with up to
8 devices.
As of late 2000, only
a few Bluetooth-equipped
products have arrived
on the market. These are
generally Bluetooth
1.0b compliant, meaning
that they transmit and
receive data at 721kbps
with 128bit security
encryption.
Bluetooth's founding members
include Ericsson, IBM,
Intel, Nokia and Toshiba.
What are the common
devices that are enabled
with BlueTooth?
Bluetooth enables short-range
wireless connections between
desktop and notebook
computers, handhelds,
personal digital
assistants, mobile
phones, camera
phones, printers, digital
cameras, headsets, keyboards
and even a computer mouse.
Highly power efficient
Bluetooth uses a low-cost,
power efficient radio
technology to support
both point-to-point and
point-to-multipoint connections.
Keeps your notebook batteries
running longer (works
with low-power consumption)
Usage
You can surf the web
and send email using your
Bluetooth mobile phone
as a dial up, transfer
images, data, documents
even video clips between
your laptop and other
devices such as servers
and PDA.
Hence 2 laptops with
Bluetooth enabled can
exchange documents between
them.
You can also print to
a Bluetooth enabled printer.
You can add Bluetooth
wireless technology to
your existing notebook
computer, eliminating
the necessity for cable
connections with USB to
Bluetooth Dongle or Bluetooth
PCMCIA card.
