Technology Overview
 Bluetooth® is
the codename for a technology specification for low-cost, short-range
radio links between mobile PCs, mobile phones and other portable
devices, and connectivity to the Internet. The Bluetooth wireless
technology specification marks the first time that major players
in the converging communications and computer industries have defined
a radio standard that allows mobile phones, hand-held computers
and PCs to communicate wirelessly with each other without manual
intervention from the user. The specification's ability to meet
cost/performance needs for a whole raft of applications will be
a significant factor in its adoption. Bluetooth wireless technology
is lower in cost than alternative wireless standards and will also
often allow a lower cost replacement for cables and connectors,
particularly when accounting for installation and maintenance.
It is about to revolutionize the personal connectivity market by
providing freedom from wired connections.

The Bluetooth Name
The Bluetooth name itself comes from the 10th century Danish
Viking King, Harald Blåtand (Bluetooth in English),
who united and controlled Denmark and Norway, hence the inspiration
of the name, by uniting products through Bluetooth.
Harald apparently enjoyed eating Blueberries, to such an extent
that his teeth were stained blue!

Today people have their computer connected by cables to the keyboard,
as well as a printer, mouse, monitor and so on. For the average
user all these cables have become a real nuisance, whether at work,
in the home, and particularly when travelling. Most of us have
experienced the annoyance messing around with al these cables and
getting tangled up in the process. Bluetooth wireless technology
will fix this, as a cable-replacement technology.
A Bluetooth chip
replaces a cable by taking the information normally carried by
it, and transmitting the information at a special 2.4GHz frequency
to a receiver Bluetooth chip, which then gives the information
received to the computer, phone, printer, handheld, headset,
or whatever.
Many other possibilities are opened up with respect to transmitting
information as Bluetooth wireless technology allows the user to
transmit data from any one Bluetooth wireless equipped product
to another. You can transmit information between a computer and
a printer, a mobile phone to a printer, or even a printer to a
printer.
With this in mind the interest in Bluetooth wireless technology
has rocketed. It can be applied to a host of applications and equipment.
In some cases adding new features and usability. In other applications
Bluetooth wireless technology will revolutionize product design
and create new products and applications.
Bluetooth chips will be used in such things as robotics, interactive
toys, within the home, meter reading, it could identify cargo,
ease the use of digital cameras and MP3s, be used in vending machines,
act as a headset that communicates with a mobile phone in your
pocket, within audio speakers, or even a refrigerator automatically
ordering over the internet the weeks shopping.
Whatever the ideas, Bluetooth wireless technology is set to take
off. The objective of this site is to make it the first point of
reference for the Bluetooth technology designer community, and help
you easily and speedily integrate Bluetooth wireless functionality
into your chosen application.
