A Bluetooth is a single digital wireless protocol that utilizes the short-ranged communications technology. It facilitates both voice and data transmissions over a short distance, usually from a mobile device. In turn, it creates a personal area network (Pans).

A Bluetooth is a single digital wireless protocol that utilizes the short-ranged communications technology. It facilitates both voice and data transmissions over a short distance, usually from a mobile device. In turn, it creates a personal area network (Pans). The intent behind the Bluetooth development is to provide a way in order to connect and exchange information between many devices. Examples would include mobile phones, telephones, computers and laptops, along with printers, digital cameras, videogame consoles and GPS receivers. This also comes with a secure and globally unlicensed Industrial, Scientific, and Medical (ISM) of 2.4 GHz of short ranged radio frequency bandwidth.

Hence, a 10th century Danish king, Harald Blatand, is where the "Bluetooth" got its name. Blatand I unified Denmark, Norway, and Sweden. The king had an affinity for teeth-staining blueberries, according to legend.

This device was first developed by Ericsson and was actually formalized in 1999, Bluetooth has then provided its own way of differentiating a device that is capable of communicating with other similar devices. This is through the sending data via a low cost and secure radio frequency. Its specifications were later developed and licensed by the so-called Bluetooth Special Interest Group (areas of telecommunication, computing, networking, and consumer electronics).

Moreover, the Bluetooth SIG, is currently releasing newer versions, along with several upgrades and backward compatibility. Bluetooth 1.2 is the most recent release. It includes the addition of an anonymity mode, which then masks the hardware address of the device in order to protect it from identity snooping and tracking. It also cuts the interference by avoiding crowded frequencies of adaptive frequency hopping.

Bluetooth headsets offer a convenient and user-friendly wireless connection. This is with the use of a Bluetooth-enabled cell phone. With its 30 feet range (10 meters) capacity, cell phones can talk with other headsets using this technology. Aside from this, PCs can talk to keyboards or printers as well.
