In the last few years, there has been much being mentioned and overheard about a wireless networking solution known as Bluetooth technology. And, even though it seems to have become a pretty common term, many people are still in the dark about what Bluetooth mobile wireless technology is and what it does.
It is a wireless technology networking communication method for short ranges. In the last few years it has been used to replace many different cables that connect either portable electronic devices, such as cell phones, or fixed electronics, such as desktop computers, to other devices. Many people are grateful to be freed from the tangle of wires that previously were needed for their electronic gadgets to communicate with each other.
Three of the greatest benefits of Bluetooth technology enabled devices are: low power usage, robustness and low cost. A Bluetooth mobile wireless technology system will be made up of an RF receiver, a base-band and a protocol stack. This simple setup provides the communication connection of different enabled devices and the exchange of various classes of data among such devices.
The RF (Radio Frequency) is a physical layer that operates on the ISM band, which is unlicensed, at 2.4GHz. There is also a frequency hop transceiver that is employed which helps to limit both interference and fade.
Unlike most of the other wireless standards today, the Bluetooth mobile wireless technology allows product developers both a link layer and an application layer, each with sets of definitions. This enables support for both voice and data applications.
It is the set of specifications that is unique to it, that allows for a definition of uniform structures. This in turn is what makes it possible for such a wide range of wireless devices to connect with each other and to share data and communicate. This level of interactivity between such an array of different types of devices was not feasible, at least not on a level that could be widely used, before the Bluetooth wireless protocol was introduced.
In just a few years, it know-how has gained global acceptance to such a degree that any of its enabled device, operating virtually anywhere in the world, is able to communicate with another Bluetooth device within the correct proximity. All its enabled electronics connect and communicate wirelessly via short-range networks which are called piconets.
Each device in a piconet that is operating with this latest technology specifications, can simultaneously connect and share data with up to seven other devices within an individual piconet. Each Bluetooth wireless device can also be connected to multiple piconets at the same times. Because piconets are dynamic and are established automatically as its enabled devices move into and out of the proximity boundaries, this is a very flexible and powerful feature of the Bluetooth system.
One of the greatest strengths of the Bluetooth knowledge, is that such an enabled device is capable of handling both voice and data transmissions at the same time without interfering with either communication. This feature means that users can enjoy a variety of convenient solutions concurrently such as: using a hands-free headset for voice calls; sending documents to a printer or fax; synchronizing a laptop or PDA; and using various mobile phone applications.
In addition to being able to get away from a myriad of wires to tangle you up, Bluetooth technology has also been designed to be surprisingly easy to setup and implement. Virtually all Bluetooth wireless devices connect with each other automatically and when it's time to share data, that is also a very straightforward task. |
