How Does a Bluetooth Headset Work:

The Personal Area Network:

• The cornerstone of Bluetooth technology is the Personal Area Network, or PAN, which creates a short range network that is accessible by all devices using the Bluetooth protocol. This is why Bluetooth headsets can be used with computers, cell phones, or even a PlayStation 3. However, before this network can be formed, connections must be formed

Headset Connection:

• In order to get your headset to work with specific devices, you have to create an initial connection. This process is known as "syncing" When you sync your headset with a device capable of receiving Bluetooth information, then you are creating an invisible link between the two devices. This link can be a part of a larger PAN that includes other devices, or as is often the case with Bluetooth headsets designed for cell phone use, the PAN is a simple one way link that sends data from the headset to the phone

Information Sharing:

• A Bluetooth headset transmits information that comes through it to the phone, PC, or console that it is synced with. The information is then transmitted through the receiving device's own Bluetooth-specific transmission method to make sure that the information gets where it needs to go. Although the process sounds complex, information in this sort of network only flows one way, and the Bluetooth signal only facilitates the initial transfer of this data. Specialized protocols and software handle the rest

About Bluetooth Headsets:

Function:

• To begin using a Bluetooth headset with a cell phone, the two devices must be paired. Initially, this process usually requires the use of a PIN number or pass code for security purposes. After the devices have connected, they are able to exchange information

Identification:

• There are different versions of Bluetooth, so users must ensure that the devices they are trying to pair are compatible. Features include voice dialing, mute selection and last-number redial. With more recent versions, greater security, lower power consumption and faster transmission speeds are available

Types:

• There are many different models and styles of Bluetooth headsets, which, like cell phones, must be charged on a regular basis. Some models are made with a small boom microphone that extends from the headset toward the mouth. Others are made without the separate extended microphone and, as a result, are smaller. There are some that have a small LCD screen that functions as a caller ID display. Although the most common devices are mono, there are also stereo Bluetooth headsets, which resemble typical headphones. These come in handy when using the phone's music player

History:

• The name Bluetooth comes from a 10th-century Danish King named Harold Blatand, who helped unify the nations of Norway, Denmark and Sweden. Not only does the name Blatand translate to "Bluetooth" in English, the product unites different types of technology and electronics

Considerations:

• Some manufacturers have three modes of Bluetooth security: nonsecure, service level-enforced security and link-level enforced security. For others, there are two levels; trusted device and nontrusted device. Bluetooth also has 128-bit encryption

Benefits:

• In addition to functioning in cell phones, computers and computer accessories, Bluetooth has other capabilities. This technology is also used in automobiles and medical devices. Beyond the high functionality of Bluetooth devices, there are other benefits that make this technology so popular. It is simple, inexpensive, the devices are small and its power consumption is low
