Bluetooth has a lot to offer with an increasingly
difficult market place. Bluetooth helps to bring
with it the promise of freedom from the cables and
simplicity in networking that has yet to be matched
by LAN (Local Area Network).
In the key marketplace, of wireless and handheld
devices, the closest competitor to Bluetooth is
infrared. Infrared holds many key features,
although the line of sight it provides doesn't go
through walls or through obstacles like that of the
Bluetooth technology.
Unlike infrared, Bluetooth isn't a line of sight and
it provides ranges of up to 100 meters. Bluetooth
is also low power and low processing with an
overhead protocol. What this means, is that it's
ideal for integration into small battery powered
devices. To put it short, the applications with
Bluetooth are virtually endless.
Disadvantages
Bluetooth has several positive features and one
would be extremely hard pressed to find downsides
when given the current competition. The only real
downsides are the data rate and security. Infrared
can have data rates of up to 4 MBps, which provides
very fast rates for data transfer, while Bluetooth
only offers 1 MBps.
For this very reason, infrared has yet to be
dispensed with completely and is considered by
many to be the complimentary technology to that
of Bluetooth. Infrared has inherent security due
to its line of sight.
The greater range and radio frequency (RF) of
Bluetooth make it much more open to interception and
attack. For this reason, security is a very key
aspect to the Bluetooth specification.
Although there are very few disadvantages, Bluetooth
still remains the best for short range wireless
technology. Those who have tried it love it, and
they know for a fact that Bluetooth will be
around for years to come.

Choosing A Bluetooth Headset
Creating a good wireless headset for Bluetooth is
actually difficult to do. The regular wired headsets
are easy to design - with ranging styles.
Bluetooth headsets can never be as small or as light
as wired headsets, simply because it needs to include
the battery and extra functions. This extra size
will impact how the headset mounts on or around
your ears.
Comfort
There seems to be two main styles of headsets for
Bluetooth. Some are held into place with a loop
around the ear. These styles are normally more
comfortable, although they may be less secure. The
others are held in place by being jammed into
your ear - and usually prove to be less comfortable.
Factors to consider
Cost
The cost is an obvious issue, something that you
really need to think about.
Ergonomics
1. Check to see if the device is easy to
quickly and conveniently put on your ear then take
it off again.
2. Are the control buttons on the headset
easy to use?
3. The headset should be comfortable to
wear for long phone calls.
4. Can you use it with a pair of glasses?
5. Check to see if you can wear it with
either ear.
6. When you aren't wearing it, you'll
need to se how you would carry it with you.
7. The weight is important as well, as you
don't want something that has the risk of falling
off.
Ease of use.
1. The commands and controls should be
easy to remember.
2. The volume level should be easy to
adjust.
3. The unit should turn on quickly.
4. The manual should be very well written
and easy for you to understand.
5. There should be a support number for
you to call if you should experience any types of
problems.
Features
1. You'll need to know about the battery,
the talk time, type, and how to tell when it is
going dead or fully charged.
2. How many devices can the unit be paired
with?
3. Compatability is also important, as
well as the warranty period.
4. Check the sound quality for both
sending and receiving audio.
5. What type of range does the headset offer
you?
Other important capabilities include voice tags,
last number redial, tranfer calls, 3 way calling,
link to other phones, call reject, and mute. You'll
also want to note if it looks attractive, and if
it's too big or too small.

Bluetooth Definition
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.

Bluetooth Basics
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.

Blue Tooth Technology
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.
