Advantages And Disadvantages

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.

10 Benefits Of 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.

2. Bluetooth is actually inexpensive
The technology of Bluetooth is cheap for companies
to implement, which results in lower costs for the
company. These savings are then passed from the
company on to you.

3. Bluetooth is automatic
Bluetooth doesn't have you set up a connection or
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.

7. Sharing voice and data
The standard for Bluetooth will allow compatible
devices to share data and voice communications.
This is great for mobile phones and headsets, as
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.
