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.
