A Brief Introduction To Bluetooth

Bluetooth was designed to allow low bandwidth wireless connections to become easy to use so even those who are new to wireless can use them. Version one.One of Bluetooth describes a low power, short range wireless networking technology that uses radio waves to send data at rates up to 720 kilobits a second.

Bluetooth Spec

The specification for Bluetooth supplies for different classes of radio that allow transmission ranges of up to 100 meters by boosting the radio power. The technology of Bluetooth isn't limited to line of sight transmission since it uses directional waves that are capable of transmitting through many obstructions.

Industry Standard

Bluetooth is an industry standard communication of wireless, meaning that it enables the connection of other devices as well, such as cell phones, computers, digital cameras, & other types of electronic devices. The specification of Bluetooth defines a radio system and a "stack" of protocol layers and profiles. The highest layer is the application layer, while the lowest layer is the radio.

The wireless technology of Bluetooth is positioned to revolutionize the personal connectivity market by providing freedom from inconvenient fixed type lines.

The specification for Bluetooth eliminates the need for cables by providing a small form factor, low cost wireless solution that will link computers, cell phones, and other electronics. Bluetooth also allows users to connect many ranges of devices fast and easily and expands communications capabilities as well.

The size of the Bluetooth radio is remarkable, as a Bluetooth radio can be built into 1 or two very small microchips then integrated into any electronic device where wireless operations would be an advantage.

Bluetooth also offers a robust link, which ensures that normal operating circumstances are not interrupted by interference from other signals that are operating in the same frequency band.

Also known for its worldwide operation, Bluetooth radio operates in the 2.four GHz frequency band, which is license free and reachable to any type of radio system in the world. No matter where you are in the world, you count on Bluetooth to work.

Security is also important. Offering advanced security mechanisms, Bluetooth ensures a high level of security. Therefore, authentification will prevent unauthorized acess to important data and make it very difficult to listen in.

Bluetooth also boasts power optimization. The radio is power friendly and the software for Bluetooth is very configurable, limiting the power consumption of equipment. The radio itself only consumes a small amount of power from a cellular phone.

Oliver Dvorak has worked with Bluetooth technology since it's inception, and is an expert in many kinds of Bluetooth devices. He runs a small information site about the subject at bluetooth.littletips.net. It includes a Bluetooth glossary

What is Bluetooth?

Bluetooth technology specifies a two-way, short-range radio link that enables communication between PCs, mobile phones, PDAs, and other computing, electronic, and home theatre equipment. With Bluetooth, you can easily synchronize contact or calendar data between a PDA and laptop, talk on a hands-free phone, or print without cables. It is a cable replacement technology like infrared, but offers many advantages over infrared.

The Bluetooth specification focuses on keeping costs low, power consumption minimal, and the size small. Its low power consumption means it can be used in battery-powered devices. Bluetooth offers faster data rates and greater transmission distances compared with infrared and there are no line-of-site restrictions. It operates at the 2.4 GHz radio frequency, ensuring worldwide operability.

History

Bluetooth is named after a 10th century Danish king, Harald Blatand (Harld Bluetooth) who was known for uniting warring groups in current-day Norway, Sweden, and Denmark. It was originally developed by Ericsson, but is now managed by the Bluetooth Special Interest Group (SIG).

The Bluetooth SIG is an industry group with members from the telecommunications, computing, and chip manufacturing industries. To date over 2000 companies are members. The Bluetooth SIG oversees a qualification program to ensure compliance with the standard and interoperability with other Bluetooth devices. Any device bearing the Bluetooth logo has successfully completed interoperability testing.

Technical Details

Speed: The gross data rate supported by Bluetooth is 1 Mbps. Actual data rates are 432 kbps for full-duplex and 721 kbps for asymmetric transmission.

Frequency: Bluetooth uses the unlicensed ISM (Industrial, Scientific, and Medical) band at 2.4 GHz. In most countries, this band is available. In a few countries it is reserved for military use, but even these countries are moving to make the band available for general use. Because Bluetooth shares the same frequency range as 802.11b WLAN products, these two technologies cannot operate in the same space under some conditions.

Security: Bluetooth is designed to be as secure as wire using authentication and 128-bit encryption. Applications can also build their own security on top of the Bluetooth connection.

Transmission distance: Bluetooth?s typical range is up to 10m. The range depends on the radio power class used. A class 2 radio has a typical range of 10m. More powerful classes support longer ranges and have higher output powers. Most devices use a class 2 radio and mobile devices, like mobile phones, where low power consumption is crucial, can only use a class 2 radio.

Architecture: With Bluetooth, up to 8 devices can be connected simultaneously. A piconet is the term for a collection of Bluetooth devices connected in an ad hoc fashion. All devices are peer units, but one device acts as a master and the other slaves for the duration of the piconet connection. Each piconet can support up to 3 full-duplex voice devices. Within a 10m area, there can be up to 10 piconets.

Applications

Bluetooth is becoming the preferred wireless technology in the WPAN (Wireless Personal Area Network). Personal applications include:

- Users can connect PCs to transfer files.
- Workers can collaborate on the same document using Microsoft NetMeeting.
- Users can connect to a printer without cables.
- Users can synchronize data between a handheld PDA and laptop.
- Users can listen to music via a wireless headset.
- Users can talk on their mobile phone with a wireless headset.
- Users can connect their laptops to the internet using their mobile phone?s GPRS or UMTS network.

Infrared And Bluetooth: Connecting Things Easier

With different electrical devices produced everyday, the problem of connecting things is becoming more and more complex. The system that comprises the computers and other electronic devices makes use of varieties of connecting wires, cables and the likes. These parts communicate trough light beams, lasers, radio signals and infrared. However, the problem with this devices and technologies is often the connection between each component. Thus, most systems are not used to their full extent due to complexities.

To simplify things, a solution was created to streamline the process of connections- bluetooth.

Bluetooth is wireless and automatic and offers users with varieties of excellent features that has recreated the art of connection. It has revolutionized the standard method of connecting things that virtually anything can be connected on a single system. From computers to mobile phones and from keyboards to headphones by means of wireless, automatic and inexpensive connection.

Other than the bluetooth technology, there are other ways of connecting things. Take for example the infrared or IR. It allows low frequency light waves which the eye can no longer interpret to transmit signals to another component. The technology is easy to create and cost of incorporating the IR device into a system is in barest minimum. Yet it has limited operations that seldom obstructs the process of connection.

Infrared technology is one to one process. Due to this limitation, you may only send signals from one component to another, like the case of the television set and the remote control. The same is true between laptops and desktops. You may only transmit signals between the two but not with another separate system, say a PDA through simultaneous actions.

It also works only on the line of sight principle wherein one has to point the infrared device directly to the host system to achieve a desirable result.

In spite of the fact that these two natures of infrared technology are obstacles to acquiring results, these same qualities have worked in advantage to connection. Because infrared devices need to be lined up directly on opposing locations, too little interference occurs between transmitters and receivers. The one to one principle on the other hand is designed to transmit signals only to the original recipient. Given that there are varieties of infrared recipients in a location, the intended recipient alone will receive the signal coming from a transmitter.

However, technology was not contented with what infrared offers. They resolved these limitations through creating the bluetooth solution.

Bluetooth technology works by transmitting signals via low frequency radio signals. The path of communication is approximately working on 2.45 gigahertz. The same frequency band is utilized in ISM devices.

The design of the technology was such that it has created a new system that does not interfere with the other devices that make use of the same frequency band (e.g. ISM). One way of doing this is the programming of the bluetooth technology to only transmit signals that has 1 milliwatt or less. Beyond this, other systems may be affected. By comparison, cell phones and other mobile devices send signals at a rate of 3 milliwatts and more.

The standard range of the bluetooth is around ten meters. This lessens the possibility that interference between device may occur. With this low transmission, it is still possible for the user to transmit bluetooth signals between obstructing walls.

Bluetooth in many ways have contributed much in connecting individual systems without being bothered by the bulk of the cables and wires.
