How Does Bluetooth Work?
Bluetooth is a standard for tiny, cheap radio chips
that can be plugged into your devices. These chips were
designed to take all of the information that your wires
normally hold, and transmit it at a special frequency
to something called a receiver Bluetooth chip. This
information is then transmitted to your device.
We will talk more about the communication later on.
This idea was conceived by Ericsson, and was eagerly
adopted by a host of other companies. The potential
for more than communication between a simple computer
and printer was soon realized, and since then, Bluetooth
technology has evolved to encompass a myriad of devices.
The fact that a Bluetooth chip is inexpensive and low
on power consumption means that it can be placed anywhere.
Because of these features, the use of Bluetooth is
growing. It is being used to gain access to LANs, to
communicate with printers, mice and more. One of the
more innovative uses is with cellular phones. Certain
phones can now be used as wireless modems.
The Bluetooth Wireless Specification
Bluetooth technology is an established standard. The
Bluetooth frequency is on a 2.45 GHz band. It is a well-tested
technology that has been driven forward by a group of
industry-leading promoters known as the Bluetooth Special
Interest Group (otherwise known as SIG). The group was
organized by nine Bluetooth promoters: IBM, Intel, Nokia,
Toshiba, 3COM, Lucent, Microsoft, Motorola and Agere.
The SIG has increased dramatically in member size, and
has agreed on making Bluetooth a royalty-free standard.
This lowers the technical cost of producing Bluetooth
products and makes these items widely available.
Bluetooth Namesake
For those who like a bit of obscure knowledge to throw
around at dinner parties, here's a little tidbit: Bluetooth
technology got its name from a Danish king. That's
right. The tenth-century Danish Viking king Harald Blatand
(English translation of Blatand is literally "Bluetooth")
is known throughout history for uniting Norway and Denmark
under Christianity. Bluetooth technology unites different
electronic devices without the use of cables or wires,
hence the namesake. King Blatand was also known for
his love of blueberries, which turned his teeth a displeasing
bluish colour.
