In the United States, Bluetooth gets absolutely no
respect. It is however, becoming more and more
common in notebooks, PDAs, and especially cell
phones. Bluetooth will provide wireless users a
way to transmit small amounts of data over short
distances.

Now, Bluetooth is facing stiff competition from
new wireless technology. Referred to as UWB or
Ultra Wideband, it promises data transfer of up
to 480 MB a second – while most current Bluetooth
devices transfer data up to 721 KB a second.

For the time being, Bluetooth devices are surely
cropping up. Below, we will look at some of
the accessories offered with Bluetooth technology.

Talking to the dashboard
When pairing it with a cell phone, the CCM Blue
Warrior car kit becomes a great speaker phone that
plugs into the power adapter of your vehicle. The
noise cancelling microphone will reduce background
noise efficiently, with the large buttons making
adjusting the speaker volume a snap. Although
the Blue Warrior is far from sexy or sleek, it’s
very practical.

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.Read the rest

With new electrical devices being produced every day,
the problem of connecting things is becoming more
and more complex in nature. The system that comprises
computers and other electronics makes use of varieties
of wires, cables, etc.

These parts will communicate through light beams,
lasers, radio signals, and infrared. The problem
however, is the devices and technology is often the
connection between each component. Therefore, most
electronic systems aren’t used to their full extent
due to the problems and imperfections.

To help simplify things, a solution was created -
the solution of Bluetooth. Bluetooth is wireless
and automatic, offering users a variety of features
that have simplified the art of connection. Bluetooth
has revolutionized the standard methods of connecting
things to enabling almost anything to be connected
to a single system.

Aside from Bluetooth, there are other ways of
connecting wireless devices. One example of such
is the IR or infrared. Infrared allows low frequency
light waves to transmit signals to another component.
This technology is easy to create and the cost of
putting the IR device… Read the rest

The technology of Bluetooth is nothing new, but in
many respects it can still seem like more of a buzz
word rather than an accepted technology. You may
see the ads for Bluetooth enabled devices, although
you still may be wondering what it is.

Capabilities
The Bluetooth definition is a wireless technology
that is a worldwide specification for a small form
factor, low cost solution that will provide link
between mobile devices and other electronic
devices.

Similiar to 802.11 b/g wireless and many cordless
telephone systems, Bluetooth operates on 2.4 GHz
radio signals. The 2.4 GHz band seems to be a bit
crowded, with interferences between the devices a
bit hard to avoid. Telephones are now being offered
at the 5.8 GHz frequency band, which will help to
remedy this.

The technical specifications of Bluetooth will
indicate a maximum transfer rate of 723 kbps with
a range of 65 – 328 feet, all depending on the
class of that particular device. The speed is a
fraction of what is offered by wireless standards,
so it’s obvious that Bluetooth… Read the rest
