Bluetooth is a specification for the use of low
power radio communications to wireless phones,
computers, and other network wireless devices over
short distances. The name Bluetooth is actually
borrowed from Harald Bluetooth, a Denmark king
more than 1,000 years ago.

The technology of Bluetooth was primarily designed
to support simple wireless networking of devices
and peripherals, which includes cell phones, PDAs,
and wireless headsets. The wireless signals that
are transmitted by Bluetooth cover short distances
of up to 30 feet, generally communicating less
than 1 MPps (Mega Byte per second).

The networks of Bluetooth feature dynamic topology
called PAN or a piconet. The piconets contain a
minumum of two and a maximum of eight peer devices.
The devices will communicate using protocols that
are part of the specification.

Even though the Bluetooth standard will utilize
the same 2.4 GHz range as 802.11b and 802.11g,
the technology isn’t suitable for a Wi-Fi
replacement. When compared to Wi-Fi, Bluetooth
is much slower, limited in range, and actually
supports less devices.

For short range devices, Bluetooth is rapidly
becoming the best. The technology is more popular
with cell phones, as Bluetooth headsets are the
way to go these days. To use Bluetooth, your
cell phone will need to have it enabled, or an
infared device somewhere on the phone.

Upcoming devices are utilizing Bluetooth as well,
such as PS3 and the Nintendo Revolution. The
wireless controllers will be Bluetooth enabled,
which will give players the cutting edge.

If you own a cell phone or other wireless device,
you should look into Bluetooth. The technology
is nothing short of spectacular, making it
something that will be around for years and
years to come. As technology gets bigger and
bigger, you can expect Bluetooth to advance
as well.

The amazing technology of Bluetooth presents a great
way of exchanging data between two wireless devices.
Unlike telephones, there are no wires or messy
leads to worry about. You can enjoy wireless
communications with short distances of up to thirty
feet.

Bluetooth also offers interoperability, meaning that
you can use your portable Bluetooth device to connect
with existing Bluetooth points. This way, you won’t
have to carry a data lead or CDs of drivers around
with you everywhere you go. You can enjoy the best
of wireless without having to worry about installing
your software.

With today’s Bluetooth, you can use your PDA and cell
phone to surf the net or check emails as you travel.
If you are in the business field, this can be very
beneficial, especially if you like to check your
email throughout the day. Bluetooth will enable you
to check your email no matter where you are – which
is great news for those who like to travel.

Bluetooth will also enable to you to transfer files
as well, such as MP3 and photo to and from your mobile
device. Bluetooth dominates the world of short range
wireless, enabling you to do more than you may
have thought possible.

One of the best things to Bluetooth and something
everyone loves is the wireless headset. Bluetooth
offers wire free headsets for your cell phone or
computer, which is great for those who like to walk
around or talk on the phone in the car, without
having to worry about your hands getting in the way.

To make things even better, you can use a Bluetooth

The technology of Bluetooth will take small area
networking to the next level by removing the need
for user intervention and help keep transmission
power very low to preserve battery power. Each
transmission signal to and from your cellular
phone will use just 1 mw of power, giving you
plenty of space on your battery to talk.

Bluetooth is a networking standard that will
work on two levels:
1. It will provide agreement at the
physical level, as Bluetooth is a radio frequency
standard.
2. It will provide agreement at the level
of protocol, where products will have to agree
on when bits are sent, how many are sent, and how
the parties in conversation can be sure the message
recieved is the same one that was sent.

The major draws to Bluetooth is the fact that
it’s wireless, inexpensive, and automatic. There
are other ways to get around wires, including
infrared. Infrared uses light waves of a lower
frequency than the human eye can, and is normally
used in television remote controls.

The technology of Bluetooth is intended to get
around the problems that normally come with
infrared systems. The 1.0 older standard of
Bluetooth has a max transfer speed of 1 MB a
second, while the 2.0 Bluetooth standard can
manage up to 3.0 MB a second. To make things
better, 2.0 is compatible with 1.0 devices.

As a solution to wireless, Bluetooth will
eliminate the need for messy cords, keeping
everything nice and neat. It’s perfect for those
who like to talk on cell phones, as you no
longer need to hold the phone next to your
ear – which is great for those who travel a
lot.
