How Does Bluetooth Work?

Bluetooth technology allows two electronic devices communicate wirelessly. These devices can be mobile phones, computers, MP3 players, PDAs, cameras, printers, etc. Most device communications are facilitated with cables. Today wireless communication has emerged and one of these technologies is Bluetooth.

Bluetooth got its name from Harald Bluetooth, the king of Denmark in the late 900.s he achieved many important triumphs including making peace between Denmark and Norway and the introduction of Christianity. Bluetooth is named after this king to show the importance of communication.

There are technical obstacles that make it hard to bring various devices together. The first concern in making two devices communicate is the physical means of communication (use of cables, infrared, radiowaves, etc.). Second, the two devices must speak the same language.

For Bluetooth to be enable communication between devices, these devices must have the Bluetooth technology included in its features. Bluetooth technology is wireless technology. Two devices in the vicinity can communicate with one another at higher speeds.

Bluetooth not only allows wireless communication between devices, it also does not need any human intervention to make such communication happen. This means that when the Bluetooth devices come into the same vicinity, they will recognize one another and start sending date.

A good example is a Bluetooth digital camera that transmits files to a Bluetooth enabled photo printer. A mobile phone can also pick phone calls when you are on the move and reroute the calls to your car’s audio system when driving so you can talk on the phone while driving – hands free.

Bluetooth was initially designed for use of mobile users. Being a mobile technology, it is small and very lightweight. It also is not expensive costing less than 50 dollars.

The device has instructions for communication. The power usage is very small. The distance that will allow communication between two devices is within 3 meters of 10 feet. Stronger versions are being introduced that use more energy and can communicate with another device up to 30 feet in diameter. The Bluetooth signals communicate at the 2.45 GHz frequency. Such frequency is greater than normal radio and TV waves.

Security is an important concern because the technology allows the device to communicate with any other device detected. The files located on a device with the technology can be corrupted and damaged when hacked or invaded by viruses. It is important for the user to understand the security features making it safe for use.
