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.
