Information |
Bluetooth wireless technology provides accessible and up to date access to the global information network, even with different pieces of equipment.
The idea for Bluetooth was created in 1994 by the Swedish company Ericsson Mobile Communications. The name of Bluetooth was chosen by the inventors of this cable-free technology in
order to honor one of their ancestors, the Viking King Harald Blåtand who dedicated himself to the unity of the Scandinavian peoples in the 10th century. The unity of a cable-free network thus commemorates his achievements.
Information connections which up to now have been made by means of cables will in future be made without them, including computers, printers, mobile phones, laptops and
organizers.

Here's how it works: |
Bluetooth chips can be embedded in electronic devices.
Bluetooth chip
These chips have two-way transmitters which can communicate over short distances by means of radio waves.
The chips can transmit voices and data over short distances without the use of cables. The chips will have the following features:
-
Inexpensive
-
Usable internationally
-
High rate of transmission
-
Low degree of energy consumption
-
Ability to correct transmission errors
-
Safe encoding functions for sensitive documents
-
Devices with Bluetooth chips can be set to automatically find and contact each other when within range
Using Bluetooth Technology, BMW intends to make the automobile into a mobile information platform. The installation of a Bluetooth chip allows simple connections to be made from
navigation systems, audio systems and car telephones to other consumer appliances such as laptops, mobile phones and organizers.
With the Bluetooth standard, the customer can buy a new piece of equipment at any time and use it in the car without any additional installations.
 Here's what Bluetooth can
do:
 |
A mobile telephone with the appropriate technology could be used at home as a cordless telephone at regular network call rates, away from home as a mobile phone and within
range of another Bluetooth telephone as a walkie-talkie free of charge.
Or a Bluetooth headphone set automatically makes the connection to mobile phone, laptop, home telephone or car. |
|
Surfing on the Internet becomes easier, too.
You can get into cyberspace via laptop, telephone or mobile phone without any cables. |

In the office, the manager will no longer have to check his calendar with the secretary in the morning, the sales rep will not have to update his customer orders from the company
network, the service rep will not have to constantly compare her telephone book with the latest lists.
With Bluetooth, all computers connect up with each other as soon as you enter the office, taking care of all these tasks on their own. And at conferences, participants can exchange
documents between their computers without cable connections.

In the automobile, you can exchange travel route data and additional travel information between the navigation system and a laptop. You can then be reached outside the vehicle to do
other tasks. You can make telephone numbers and addresses from the organizer database available via the car telephone or the navigation system. You can update appointments and use the hands-free system of the mobile phone without cable
connections, or your kids can watch TV in the rear seat, listen to music on headphones or surf the Internet.

Bluetooth Specification is a de facto standard containing the information required to ensure that
diverse devices supporting the Bluetooth wireless technology can communicate with each other worldwide. The Core part specifies components such as the radio, baseband, link manager, service discovery protocol, transport layer, and
interoperability with different communication protocols. The Profiles part specifies the protocols and procedures required for different types of Bluetooth applications.
