How Bluetooth Works

Bluetooth is a wireless technology used for transmitting data over short distance. It can get used for a number of purposes from simple voice headsets to computer data transfers. This flexibility of usage explains why Bluetooth is such a widespread standard in modern computers, cellphones and even automobiles.

Bluetooth works in the 2400 to 2480 MHz range

The Bluetooth standard uses short wavelength radio transmissions in the 2400 to 2480 MHz range to transmit data. These frequencies are within the ISM band and are typically very short range. This is what gives Bluetooth headsets much of their appeal since the Bluetooth standard is very reliable at short ranges, and the headset never has to travel very far from the phone it is connected too.

Bluetooth creates a high security environment

Bluetooth is also highly popular because of the high level of security built into it. Rather than creating an open network like Wi-Fi, Bluetooth creates a personal area network, or PAN, to communicate. This system is designed to only communicate with the devices that are part of the creation of the network itself, giving the standard high security reliability. Outside intruders cannot push their way in like they can with other wireless standards.

The Bluetooth standard has gained widespread acceptance within the electronics industry due to its highly reliable, stable and secure wireless capabilities. While it does not have the range and draws more power than Wi-Fi, for short range applications the greater bandwidth and high security of Bluetooth is just unbeatable.
