What Is Bluetooth Wireless Technology?

Bluetooth is a wireless technology that “unplugs” many devices that traditionally would operate via cables. This short range communications technology offers secure wireless connections that are for the most part low in power consumption and allow many devices to communicate with each other and over a network.

The goal was that any Bluetooth device can connect to any other Bluetooth device anywhere in the world. It is commonly accepted that this goal has been reached. This connectivity is achieved through dynamic short range networks that are referred to as Piconets. A single active Piconet, which comes into being when two or more Bluetooth devices get within proximity of each other, will allow up to seven other Bluetooth devices to freely communicate. This all happens invisibly to the users, and since a single device can be in more than one Piconet at a given time, there is no theoretical limit to the number of devices that can be networked.

Bluetooth wireless technology can handle both voice and data traffic. This gives users the freedom to utilize the popular “hands free” phone headsets, as well as wireless laptops, printers, PDAs and phones all that can access each other without networking cables.

Despite the wireless nature of this technology, there is seldom data loss due to interference. Bluetooth uses AFH, or Adaptive Frequency Hopping, to avoid or move away from frequencies that have a level of interference that would adversely affect the user experience. This process is behind the scenes and dynamic, so a user could be hopping through many frequencies without ever knowing it.
