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.
