With different electrical devices produced everyday, the problem of connecting things is becoming more and more complex. The system that comprises the computers and other electronic devices makes use of varieties of connecting wires, cables and the likes. These parts communicate trough light beams, lasers, radio signals and infrared. However, the problem with this devices and technologies is often the connection between each component. Thus, most systems are not used to their full extent due to complexities.

To simplify things, a solution was created to streamline the process of connections- bluetooth.

Bluetooth is wireless and automatic and offers users with varieties of excellent features that has recreated the art of connection. It has revolutionized the standard method of connecting things that virtually anything can be connected on a single system. From computers to mobile phones and from keyboards to headphones by means of wireless, automatic and inexpensive connection.

Other than the bluetooth technology, there are other ways of connecting things. Take for example the infrared or IR. It allows low frequency light waves which the eye can no longer interpret to transmit signals to another component. The technology is easy to create and cost of incorporating the IR device into a system is in barest minimum. Yet it has limited operations that seldom obstructs the process of connection.

Infrared technology is one to one process. Due to this limitation, you may only send signals from one component to another, like the case of the television set and the remote control. The same is true between laptops and desktops. You may only transmit signals between the two but not with another separate system, say a PDA through simultaneous actions.

It also works only on the line of sight principle wherein one has to point the infrared device directly to the host system to achieve a desirable result.

In spite of the fact that these two natures of infrared technology are obstacles to acquiring results, these same qualities have worked in advantage to connection. Because infrared devices need to be lined up directly on opposing locations, too little interference occurs between transmitters and receivers. The one to one principle on the other hand is designed to transmit signals only to the original recipient. Given that there are varieties of infrared recipients in a location, the intended recipient alone will receive the signal coming from a transmitter.

However, technology was not contented with what infrared offers. They resolved these limitations through creating the bluetooth solution.

Bluetooth technology works by transmitting signals via low frequency radio signals. The path of communication is approximately working on 2.45 gigahertz. The same frequency band is utilized in ISM devices.

The design of the technology was such that it has created a new system that does not interfere with the other devices that make use of the same frequency band (e.g. ISM). One way of doing this is the programming of the bluetooth technology to only transmit signals that has 1 milliwatt or less. Beyond this, other systems may be affected. By comparison, cell phones and other mobile devices send signals at a rate of 3 milliwatts and more.

The standard range of the bluetooth is around ten meters. This lessens the possibility that interference between device may occur. With this low transmission, it is still possible for the user to transmit bluetooth signals between obstructing walls.

Bluetooth in many ways have contributed much in connecting individual systems without being bothered by the bulk of the cables and wires.

The technology of Bluetooth wireless is a short
range communications method intended to replace
the cables that connect portable or fixed devices
while maintaining the highest levels of security.

The key features offered by Bluetooth include
low power and low cost. The specification in
Bluetooth defines a uniform structure for a wide
range of devices to communicate and connect with
one another.

The technology behind Bluetooth has achieved
global satisfaction such as enabled devices, almost
everywhere in the world. Bluetooth devices will
connect and communicate without wires through
short range and networks known as piconets.

Each device will simultaneously communicate with
up to seven other devices within a single piconet,
meaning that each device can also belong to
several piconets simultaneously. The piconets
are dynamically established as Bluetooth enabled
devices enter and leave the proximity of radio.

A fundamental to Bluetooth strength is the
ability to handle both data and voice transmissions
simultaneously. This will enable users to enjoy
varieties of innovative solutions such as hands
free talking, printing and fax capabilities,
and other applications.

Specifications
Unlike other standards of wireless, the Bluetooth
specification gives product developers both a
link layer and application layer definitions,
which will help support data and voice applications.

Spectrum
The Bluetooth technology operates in the industrial
and scientific band at 2.4 to 2.485 GHz, using a
spread spectrum, frequency hopping signal.

Interference
The adaptive frequency hopping of Bluetooth
technology was designed to reduce interference
between wireless technologies that share the 2.4
GHz spectrum. Adaptive frequency hopping (AFH)
works well within the spectrum to take full
advantage of the frequency available.

AFH hopping allows for more efficient transmission
within the spectrum, which provides users with
greater performance even if they are using other
technologies along with Bluetooth.

With Bluetooth being very popular with wireless, it’s
no wonder there are many applications available for
the technology. Below, you’ll find the applications
for Bluetooth.

1. Wireless networking between laptops and desktop
computers, or desktops that are in a confined space
and little bandwidth is needed.

2. Peripherals such as mice, keyboards, and printers.

3. Cell phones with Bluetooth technology have been
sold in large numbers, as they are able to connect to

menu, you can choose to either send a file or
browse devices, quickly and easily. Or, you can
click the sync button in iSync to update your
cell phone or Palm OS handheld.

The Mac and GSM/GPRS mobile phone with Bluetooth
work to make each other more useful. By using
iSync, you can keep your phone updated without
having to type any info, as you can keep the
information in the more manageable address book
on your Mac instead.

You can also use your Bluetooth enabled Mac to
print documents and digital images to select a
printer that also supports the technology of
Bluetooth. Or, you can also use a headset to
talk to your friends during an iChat session.

Your Mac also has the ability to use Bluetooth
technology to communicate with your Palm OS
handheld. This way, you can perform a HotSync
operation without using any cables. You can also
send your business card or calendar events directly
to someone else’s handheld usingthe technology of
Bluetooth.

The implementation of Bluetooth by Apple is the
latest in a series of moves that have caused
great shift in the computer industry. Apple
established USB as the standard interface with
the launching of the first Mac back in 1998.

Since then, Apple established the 802.11 wireless
standard of networking with the launch of the
iBook and AirPort in 1999. During 2003, Apple
launched AirPort Extreme, which was based on
the new 802.11g high speed technology of wireless.

Now, Bluetooth helps to further strengthen the
dominant position of the Mac in wireless
communications, helping to preserve Apple’s
reputation for being the first to market with
innovative technology that integrates right into
the operating system.

Below, are 10 benefits and reasons to use Bluetooth

it is, you can count on it being around for years
to come. As more and more devices start to use
Bluetooth technology, more manufacturers will be
eager to make their products compatible. A chain
reaction will occur, making Bluetooth the standard
for cutting edge wireless.

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
GPS device for satellite navigation on your PDA,
laptop, or mobile. If you travel – this can be
really great to have.

Because it meets the basic needs of connectivity in
close range, Bluetooth has a very bright future
ahead of it. Bluetooth is actually the result of
initiatives from nine leading communications and
computer industry giants, including 3-COM, Sony,
Lucent, IBM, Nokia, Microsoft, etc.

Since the forming of the original group, more than
1,800 manufacturers around the world have joined
the initiative. According to reports, the Bluetooth
technology is expected to be built into more than
100 million devices, with over 670 million enabled
Bluetooth devices.

Resulting from the amazing success of WAP (Wireless
Application Protocol), the adoption of smart phones
and hand held devices, Bluetooth can easily have
an amazing impact on your day to day life. Bluetooth
is one of the key technologies that can help to
make the mobile information society happen, by
blurring the possibilities between home, the office,
and the outside world.

The seamless integration and connectivity that
Bluetooth promises will make it possible to explore
a wide range of interactive and highly transparent
personalized services which were actually quite
difficult to dream of simply because of the
complexity involved with making such devices
communicate with each other.

Many Bluetooth pilot products have already been
rolled into the market and backed by big vendors,
which is a healthy sign for the overall acceptance
of the technology. The support for Bluetooth isn’t
limited to companies that develop only Bluetooth
enabled products.

The applications for Bluetooth can have great
impacts on other industries as well. The adoption
of Bluetooth technology is expected to spread
throughout the industry of computers.

Unlike infrared technology, Bluetooth is used by
many different wireless devices. Bluetooth offers
exceptional quality for short range wireless, even
going through walls and obstructions. While
infrared is the biggest competitor at this time,
Bluetooth far surpasses it, proving to millions that
it is the wireless communication technology of the
present day and age.

In the beginning, Bluetooth started with version 1.0,
then gradually moved from there. The current
version is 2.0+EDR, with another version currently
in development. The technology behind the Bluetooth
specification always getting better and better,
which is why it’s so popular.

In the future, you can expect the technology
behind Bluetooth to get better. Bluetooth has
proven to be the wireless standard of the future,
offering you wireless connectability for hundreds
of different devices. For cell phones or other forms
of wireless connections, Bluetooth is the one
technology that you don’t want to find yourself
without.

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.

Bluetooth, Smartphones And Apple

Laptops are the firsts ones to use bluetooth technology. But technology is inevitable and today, more and more gadgets, such as smartphones uses the same technology to communicate with other devices.

Bluetooth And Apple The new Apple powerbook G4 are among the first computers to offer Bluetooth technology 2.0+EDR. The 2.0+EDR technology, which still backwards compatible with 1.0, is up to three times faster than previous versions, offering maximum data rate transfers of up to 3 MBps.

Now, Bluetooth helps to further strengthen the dominant position of the Mac in wireless communications, helping to preserve Apple’s reputation for being the first to market with innovative technology that integrates right into the operating system.

Constantly evolving, the technology of Bluetooth
started off as a basic wireless connection standard
but has since then been adapted and proven with many
different uses and functions.

A good example is Bluetooth for cell phones. It
enables mobile users to connect to their hands free
headset without using wires. Bluetooth technology
will also allow mobile phone users to connect
with their hands free kit as well.

Another handy use of Bluetooth is file sharing. It
allows the sharing of files between two cell phones,
between a cell phone and computer, which makes the
sharing of files a snap. If you have a cell phone
and computer, you can easily transfer data between
the two.

Say for example you wanted to put an MP3 on your
phone from your computer you could do it easily
with Bluetooth. All you would need is a Bluetooth
adapter for your computer. It doesn’t stop with the
swapping of files either,as you can use your computer
and phone to synchronise phone books, send SMS messages,
and much more.

Although Bluetooth may be dandy for cell phones,
it also comes in handy for the home office as well.
Utilizing Bluetooth is a great way to set up a
home office – two computers, a printer, and even a
scanner. They all can be connected using Bluetooth
technology with effective ranges of up to 10 meters.

The technology and devices of Bluetooth will be
around for years and years to come. As years go
by, Bluetooth will provide even better wireless
solutions for different applications. Even though
Bluetooth has a short range, it has that short
range for a reason. Bluetooth is easily the best
in wireless technology – which it continues to
prove time and time again.
