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.

Below, are 10 benefits and reasons to use Bluetooth
technology.

1. Wireless
As you probably already know, there are many benefits
and advantages to using wireless devices. Along with
improving safety as a result of eliminating wires
you don’t need, wireless also offers you plenty of
other advantages. When traveling with your laptop
or other wireless devices, you’ll no longer have to
worry about bringing connection cables.

push any buttons. When two or more devices enter
a range of up to 30 feet of each other, they will
automatically begin to communicate without you
having to do anything.

4. Standardized protocol
Bluetooth is standardized wireless, meaning that
a high level of compatibility among devices is
guaranteed. Bluetooth will connect devices to
each other, even if they aren’t the same model.

5. Low interference
Bluetooth devices almost always avoid interference
from other wireless devices. Bluetooth uses a
technique known as frequency hopping, and also
low power wireless signals.

6. Low energy consumption
As a result of Bluetooth using low power signals,
the technology requires very little energy and will
use less battery or electrical power as a result.
This is an excellent benefit for mobile devices,
as Bluetooth won’t drain the battery.

Bluetooth simplifies driving and talking on your
cell phone.

8. Instant PAN (Personal Area Network)
You can connect up to seven Bluetooth devices to
each other within a range of up to 30 feet, forming
a piconet or PAN. For a single room, you can
also set up multiple piconets.

9. Upgradeable
Upgradeable is the standard for Bluetooth. There
are newer versions of Bluetooth in the works,
which offer many new advantages and backward
compatible with older versions.

10. The technology stays
Bluetooth technology is a world wide, universal
wireless standard. With it being as popular as
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.

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 technology offers three different types
of defined ranges, based on output ranges. Class
1 devices are the most powerful, as they can have
up to 100 mW of power, with a regular antenna
giving them a range of around 130 – 330 feet.

The class 2 devices are lower power, offering up
to 2.5 mW of power. A regular antenna will give
them a range of around 50 – 100 feet. Class 3
devices use even less power, up to 1 mW of power
to be exact. With a regular antenna, they will
have a range of around 16 – 33 feet.

Even though you may not realize it, Bluetooth
wireless technology has never been intended for
anything other than short distance types of
communication. With Bluetooth wireless, the short
range is actually a benefit.

For one, the short range will reduce the change of
interference between your devices and those that
belong to others who are nearby. Overall, this
is a basic type of security, designed to protect
you and your devices.

Secondly, the lower power used for short range
means a longer battery life. Most Bluetooth
devices will get their power from a battery,
meaning that anything you can do to lengthen the
battery life is very important.

The wireless networking offered by Bluetooth is
actually among the best, even though it uses
short range communication. Bluetooth is used
with wireless controllers, the internet, and
even wireless headsets.

For the best in short range technology, Bluetooth
is extremely hard to beat. If you’ve never tried
Bluetooth before, now is the time. It’s the best
with wireless networking, especially for those
who enjoy hands free talking on their cell phone.

Other wireless technology such as Garmin GPS utilizes complex wireless systems that let you know where you are, on any place in the world.

Bluetooth In Action

In the United States, Bluetooth gets positively no
esteem. Bodily is however, becoming new and added
accepted in notebooks, PDAs, and especially cell
phones. Bluetooth will give wireless users a
conduct to transmit inconsequential amounts of data over short
distances.

Soon, Bluetooth is diverse stiff competition from
unseasoned wireless technology. Referred to in that UWB or
Ultra Wideband, true promises data transfer of up
to 480 MB a second – bout most current Bluetooth
devices transfer data up to 721 KB a second.

For the stage being, Bluetooth devices are just so
cropping up. Below, we will regarding at some of
the accessories offered stifle Bluetooth technology.

Language to the dashboard
