Multimedia Production

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 into a system is rather low.

Infrared technology is a one to one process.  Due
to the limitation, you may only send signals from one
device to another, similar to a television set and
remote control.  You can only transmit signals
between the two although not with a seperate system.

Aside from the fact that these two natures of
infrared are obstacles to acquiring results, these
same qualities have worked in advantage to the
connection.  Infrared devices need to be lined up
directly, meaning too little interference can occur
between the transmitters and receivers.

The technology behind Bluetooth works by transmitting
signals through low frequency radio signals.  The
path of communication is working on 2.45 GHz, which
is the same frequency band used in ISM devices.

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.  Being the first company
to certify a system with 2.0+EDR, Apple continues
to make great use of the Bluetooth technology.

Full support
In addition to the powerbook G4 portables, there
are other Bluetooth enabled computers available
from Apple, including the iBook, iMac G5, eMac,
and the Power Mac G5.

Making life easier
When you turn the Bluetooth feature on, your Mac
can easily perform a file transfer or even a
synchronization.  From the Bluetooth selection
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.

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.
