Bluetooth Basics

The technology of Bluetooth wireless is a short range communications method intended to replace the cables that connect portable or fixed devices while maintaining the highest levels of security. The key features offered by Bluetooth include low power and low cost. The specification in Bluetooth defines a uniform structure for a wide range of devices to communicate and connect with one another. The technology behind Bluetooth has achieved global satisfaction such as enabled devices, almost everywhere in the world. Bluetooth devices will connect and communicate without wires through short range and networks known as piconets. Each device will simultaneously communicate with up to seven other devices within a single piconet, meaning that each device can also belong to several piconets simultaneously. The piconets are dynamically established as Bluetooth enabled devices enter and leave the proximity of radio. A fundamental to Bluetooth strength is the ability to handle both data and voice transmissions simultaneously. This will enable users to enjoy varieties of innovative solutions such as hands free talking, printing and fax capabilities, and other applications. Specifications Unlike other standards of wireless, the Bluetooth specification gives product developers both a link layer and application layer definitions, which will help support data and voice applications. Spectrum The Bluetooth technology operates in the industrial and scientific band at 2.4 to 2.485 GHz, using a spread spectrum, frequency hopping signal. Interference The adaptive frequency hopping of Bluetooth technology was designed to reduce interference between wireless technologies that share the 2.4 GHz spectrum. Adaptive frequency hopping (AFH) works well within the spectrum to take full advantage of the frequency available. AFH hopping allows for more efficient transmission within the spectrum, which provides users with greater performance even if they are using other technologies along with Bluetooth.

Bluetooth Applications

With Bluetooth being very popular with wireless, it's no wonder there are many applications available for the technology. Below, you'll find the applications for Bluetooth. 1. Wireless networking between laptops and desktop computers, or desktops that are in a confined space and little bandwidth is needed. 2. Peripherals such as mice, keyboards, and printers. 3. Cell phones with Bluetooth technology have been sold in large numbers, as they are able to connect to computers, PDAs (Personal Data Assistant), and various other devices. The standard also includes the support for more powerful and longer range devices. 4. The transfer of files, images and MP3, between mobile phones. 5. Certain MP3 players and digital cameras to transfer files to and from computers. 6. Bluetooth technology headsets for smart phones and cell phones. 7. Data logging equipment that transmits data to a computer via Bluetooth technology. 8. Sony Playstation 3 and Nintendo Revolution will both use Bluetooth technology for their wireless controllers. For Bluetooth, there are literally hundreds of different applications and devices available for you to use or purchase. As you may already know, Bluetooth is the most popular wireless technology in the world. It's very reliable, very dependable, and very hard to crack into. There are many other applications for Bluetooth in development now, many of which plan to take the wireless age to the next level. Video game systems are using Bluetooth technology as well, for their wireless controllers. This is great news for gaming fans, as Bluetooth offers the best in wireless data transmission. If your curious about applications for Bluetooth that are still in development, you can search on the internet. You can find all sorts of information, especially when it comes to Bluetooth. As the future arrives, you can expect Bluetooth to bring bigger and better things. (word count 300) PPPPP

Bluetooth And Infared

With new electrical devices being produced every day, the problem of connecting things is becoming more and more complex in nature. The system that comprises computers and other electronics makes use of varieties of wires, cables, etc. These parts will communicate through light beams, lasers, radio signals, and infrared. The problem however, is the devices and technology is often the connection between each component. Therefore, most electronic systems aren't used to their full extent due to the problems and imperfections. To help simplify things, a solution was created - the solution of Bluetooth. Bluetooth is wireless and automatic, offering users a variety of features that have simplified the art of connection. Bluetooth has revolutionized the standard methods of connecting things to enabling almost anything to be connected to a single system. Aside from Bluetooth, there are other ways of connecting wireless devices. One example of such is the IR or infrared. Infrared allows low frequency light waves to transmit signals to another component. This technology is easy to create and the cost of putting the IR device into a system is rather low. Infrared technology is a one to one process. Due to the limitation, you may only send signals from one device to another, similar to a television set and remote control. You can only transmit signals between the two although not with a seperate system. Aside from the fact that these two natures of infrared are obstacles to acquiring results, these same qualities have worked in advantage to the connection. Infrared devices need to be lined up directly, meaning too little interference can occur between the transmitters and receivers. The technology behind Bluetooth works by transmitting signals through low frequency radio signals. The path of communication is working on 2.45 GHz, which is the same frequency band used in ISM devices. (word count 303) PPPPP
