Bluetooth In Action

Oct 2009

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.

Tiny tuning box
Part MP3 player and part hands free phone, the
compact and lightweight Sony HBM-30 is an attractive
gadget that lets you accept calls with minimal
interruption of your tunes.  When you get an incoming
call it will automatically pause your music, then
you speak into the built in microphone that you
can wear around your neck or clip to your clothes.

The pen
With Nokia’s SU-1B digital pen, you can doodle and
make hand written notes in ink on a special pad
then transmit them from the pad to your Bluetooth
phone.  Being an alternative to typing on a cell
phone keypad, the pen is very handy, although a
pricey tool from MMS fans.

Snapshots
If you want to make slide shows with your camera
photos, the Nokia SU-2 image viewer will let you
disply your pictures on a TV or projector.  Simply
hook this square gray device to your TV’s input
with the built in cable, then beam the pictures
to the SU-2 from your Bluetooth enabled phone and
the photo fest will begin.

This device is a snap to set up and use, although
it displays resolutions of up to 640 by 480.  If
you have a newer phone that takes high resolution
photos, you won’t be able to use the Nokia SU-2
image viewer.

Keep in mind, the 640 by 480 pixel photos will
appear blocky on TV screens, no matter what you
do.  If your phone can send batches of photos, you
can create a slide show – although Nokia claims
you can use sequentially beamed shots as well.

Below, you’ll find a list of the most used terms in
Bluetooth technology.  They can serve as a look up,
or to help you learn more about Bluetooth terms in
general.

2 in 1 handset
The situation where a subscriber’s handset is acting
as a remote handset to a base unit that provides a
network connection.

3G
Third generation, referring to the next generation
of digital phone technology.

802.11 WLAN
A wireless LAN specification defined by the IEEE.

Access code
Each base band packet will start with an access code,
which can be one of 3 types – CAC, DAC, and IAC.

ACK
Acknowledge.

ACL
Asynchronous Connectionless Link.  This is one of the
two types of data links that are defined for Bluetooth.

ACO

Active mode
During the active mode, the unit will actively
participate on the channel.  The master will schedule
the transmission based on traffic demands from the
different slaves.

AP
Access point.

Authentification
The process of verifying who is at the opposite end
of the link.

Authentification device
A device whose identity has been verified during the
lifetime of the current link based on the
authentification procedure.

Baseband
This describes the specification of the digital
signal processing aspect of the hardware – the
controller – which carries out the baseband
protocols.

BB
Abreviation of baseband.

BD
Bluetooth device.

BER

Bluetooth Definition

Oct 2009

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.

different applications and devices available for you
to use or purchase.  As you may already know,
Bluetooth is the most popular wireless technology
in the world.  It’s very reliable, very dependable,
and very hard to crack into.

There are many other applications for Bluetooth in
development now, many of which plan to take the
wireless age to the next level.  Video game systems
are using Bluetooth technology as well, for their
wireless controllers.  This is great news for gaming
fans, as Bluetooth offers the best in wireless
data transmission.

If your curious about applications for Bluetooth
that are still in development, you can search on
the internet.  You can find all sorts of information,
especially when it comes to Bluetooth.  As the
