BLUE TOOTH
Bluetooth is a radio standard primarily designed for low power consumption, with a short range (power class dependent: 1 meter, 10 meters, 100 meters) and with a low-cost transceiver microchip in each device.
Bluetooth lets these devices communicate with each other when they come in range, even if they are not in the same room, as long as they are within up to 100 meters of each other, dependent on the power class of the product.:
Bluetooth is an industrial specification for wireless personal area networks (PANs), also known as IEEE 802.15.1. Bluetooth provides a way to connect and exchange information between devices like personal digital assistants (PDAs), mobile phones, laptops, PCs, printers and digital cameras via a secure, low-cost, globally available short range radio frequency.
The name Bluetooth was born from the 10th century king of Denmark, King Harold Bluetooth (whose surname is sometimes written as Bluetooh), who engaged in diplomacy which led warring parties to negotiate with each other. The inventors of the Bluetooth technology thought this a fitting name for their technology which allowed different devices to talk to each other
Bluetooth applications
———————————-
* Wireless networking between desktops and laptops, or desktops in a confined space and where little bandwidth is required
* Bluetooth peripherals such as printers, mice, keyboards and digital pens.
* Bluetooth cell phones have been sold in large numbers, and are able to connect to computers, personal digital assistants (PDAs), certain automobile handsfree systems and various other devices. The standard also includes support for more powerful, longer-range devices suitable for constructing wireless LANs.
* Transfer of files (images, mp3s, etc) between mobile phones, Personal digital assistants (PDAs) and computers via OBEX
* Certain mp3 players and digital cameras to transfer files to and from computers
* Bluetooth headsets for mobile phones and smartphones
* Some testing equipment is Bluetooth enabled
* Some medical applications are under development
* Certain GPS receivers transfer NMEA data via Bluetooth
* Bluetooth car kits — In 2002 Audi, with the Audi A8, was the first motor vehicle manufacturer to install Bluetooth technology in a car, enabling the passenger to use a wireless in-car phone. Later, BMW added it as an option on its 3 Series, 5 Series, 7 Series and X5 vehicles. Since then, other manufacturers have followed suit, with many vehicles, including the 2004 Toyota Prius and the 2004 Lexus LS 430. The Bluetooth car kits allow users with Bluetooth-equipped cell phones to make use of some of the phone’s features, such as making calls, while the phone itself can be left in a suitcase or in the boot/trunk, for instance. Companies like Parrot or Motorola manufacture Bluetooth hands-free car kits for well-known brand car manufacturers.
* Certain data logging equipment transmits data to a computer via Bluetooth.
* For remote controls where infrared was traditionally used.
* Hearing aids — Starkey Laboratories have created a device to plug into some hearing aids [2]
* A number of unscrupulous advertising firms in the greater Los Angeles area debuted Bluetooth-enabled billboards along roads and highways, broadcasting advertisements to passing motorists’ Bluetooth-enabled cellular phones or PDAs, much to the motorists’ annoyance. [3]
* Nintendo’s Wii and Sony’s Playstation 3 will use Bluetooth technology for its wireless controllers. Also Hip Gear has already released a Bluetooth controller for the Xbox.
* Newer model Zoll Defibrilators for the purpose of transmitting Defibrilation Data and Patient Monitoring/ECG data between the unit and a reporting PC using Zoll Rescue Net software.
* The upcoming LEGO Mindstorms NXT will use Bluetooth as an alternative way to receive programs from the computer.
