Why do you
need Bluetooth?
Your computer is typically
connected by a table to various peripherals such as a mouse,
keyboard, printer, monitor, scanner, and more. These cables
create a confusing, tangles mess that limits our ability to
be mobile.
Additionally, televisions, VCRs, CD players, speakers,
telephones and various other electronic devices communicate
with each other using a variety of wires, cables, radio
signals and infrared light beams, and an even greater
variety of connectors, plugs and protocols.
Companies that manufacture electronic devices have realized
that the mind boggeling array of cables and connectors
involved in their products makes it difficult for even
experts to correctly set up a system. Setting up computers
and home entertainment systems becomes terrifically
complicated when the person buying the equipment has to
learn and remember all the details to connect all the parts.
In order to make home electronics more user friendly, a
better way was needed for all the electronic parts of our
life to communicate. That's where Bluetooth comes in.
Who invented Bluetooth?
Bluetooth was the brainchild of
Ericsson and has become a standard for a small, inexpensive
radio chip that can be plugged into mobile phones as well as
computers and their peripherals. A Bluetooth chip replaces
cables by taking the information normally carried by the
cable, and transmitting it at a special frequency to a
receiver Bluetooth chip, which will then give the
information received to the computer, phone,
or other electronic device.
What can Bluetooth do?
Bluetooth allows any sort of
electronic devices to make their own connections without
wires, cables or any direct action from a user. Bluetooth is
intended to be a standard that works at two levels. First,
it provides agreement at the physical level via a
radio-frequency standard. Secondly, it also provides
agreement at the next level up, where products have to agree
on when bits are sent, how many will be sent at a time and
how the parties in a conversation can be sure that the
message received is the same as the message sent.
Because Bluetooth is wireless, when you travel, you don't
have to worry about keeping track of a briefcase full of
cables to attach all of your components, and you can design
your office without wondering where all the wires will go.
It's not going to raise the cost of electronic devices
because it's inexpensive. The user of Bluetooth devices
doesn't need to do anything special to make them work. The
devices find one another and strike up a conversation
without any user input at all.
The projected low cost of a Bluetooth chip (around $5), and
its low power consumption, means you can literally place one
anywhere. Many ideas are coming forward such as Bluetooth
chips in freight containers to identify cargo when it
arrives or a headset that communicates with a mobile phone
in your pocket, or even in the other room. Or, how about
your refrigerator communicating with your computer to update
your grocery list when you run out of an item?
Who owns Bluetooth?
Bluetooth is not owned by one
individual company. Bluetooth is a specification for a
wireless technology, developed by members of the Bluetooth
Special Interest Group (SIG). The SIG, founded in February
1998, initially consisted of five companies - Ericsson,
Intel, Toshiba, Nokia & IBM. Today more than 1300 companies
have joined the SIG to work for an open standard for the
Bluetooth concept. By signing a zero cost agreement,
companies can join the SIG and qualify for a royalty-free
licence to build products based on the Bluetooth technology.
Why did
they name it Bluetooth?
Have you been wondering where
the name Bluetooth came from? Harald Blåtand (translated as
Bluetooth in English) was king of Denmark in the late 900s.
He united and controlled Denmark and Norway into a single
kingdom then introduced Christianity into Denmark. This
unity was inspiration for the name: uniting devices through
Bluetooth. |
