Bluetooth Technology Intro




The technology of Bluetooth is nothing new, but in



many respects it can still seem like more of a buzz



word rather than an accepted technology. You may



see the ads for Bluetooth enabled devices, although



you still may be wondering what it is.





Capabilities



The Bluetooth definition is a wireless technology



that is a worldwide specification for a small form



factor, low cost solution that will provide link



between mobile devices and other electronic



devices.





Similiar to 802.11 b/g wireless and many cordless



telephone systems, Bluetooth operates on 2.4 GHz



radio signals. The 2.4 GHz band seems to be a bit



crowded, with interferences between the devices a



bit hard to avoid. Telephones are now being offered



at the 5.8 GHz frequency band, which will help to



remedy this.





The technical specifications of Bluetooth will



indicate a maximum transfer rate of 723 kbps with



a range of 65 - 328 feet, all depending on the



class of that particular device. The speed is a



fraction of what is offered by wireless standards,



so it's obvious that Bluetooth doesn't really



pose a threat to replacing your wireless network.





Applications



There are numerous products that will take advantage



of Bluetooth capabilities, such as laptops, PDAs,



headphones, and even wireless printer adapters.





A lot of laptops out there will include an onboard



Bluetooth adapter which allows the system to



connect to any Bluetooth device right out of the



box. For computers that don't have an adaptor



built right in, there are several USB adaptors



available for Bluetooth.





For an awesome technology, Bluetooth is actually



hard to compete with. For short range wireless,



Bluetooth is easily one of the best. The standard



for Bluetooth keeps getting better and better,



making it a wireless technology that will be around



for years and years to come.
